101 <p>If you have basic knowledge of using FTP and are sure your hosting service or server will run phpBB3 you can use these steps to quickly get started. For a more detailed explanation you should skip this and go to <a href="#require">section 2</a> below.</p>
102
103 <ol>
104 <li>Decompress the phpBB3 archive to a local directory on your system.</li>
105 <li>Upload all the files contained in this archive (retaining the directory structure) to a web accessible directory on your server or hosting account.</li>
106 <li>Change the permissions on config.php to be writable by all (666 or -rw-rw-rw- within your FTP Client)</li>
107 <li>Change the permissions on the following directories to be writable by all (777 or -rwxrwxrwx within your FTP Client):<br />
108 <code>store/</code>, <code>cache/</code>, <code>files/</code> and <code>images/avatars/upload/</code>.</li>
109 <li>Using your web browser visit the location you placed phpBB3 with the addition of install/index.php or pointing directly to install/, e.g. http://www.mydomain.com/phpBB3/install/, http://www.mydomain.com/forum/install/ etc.</li>
110 <li>Click the <em>INSTALL</em> tab, follow the steps and fill out all the requested information.</li>
111 <li>Change the permissions on config.php to be writable only by yourself (644 or -rw-r--r-- within your FTP Client)</li>
112 <li>phpBB3 should now be available, please <strong>MAKE SURE</strong> you read at least <a href="#postinstall">Section 6</a> below for important, security related post-installation instructions.</li>

133 <p>phpBB3 has a few requirements which must be met before you are able to install and use it.</p>
134
135 <ul>
136 <li>A webserver or web hosting account running on any major Operating System with support for PHP</li>
137 <li>A SQL database system, <strong>one of</strong>:
138 <ul>
139 <li>MySQL 3.23 or above (MySQLi supported)</li>
140 <li>PostgreSQL 7.3+</li>
141 <li>SQLite 2.8.2+</li>
142 <li>Firebird 2.0+</li>
143 <li>MS SQL Server 2000 or above (directly or via ODBC)</li>
144 <li>Oracle</li>
145 </ul>
146 </li>
147 <li><strong>PHP 4.3.3+ (>=4.3.3, >4.4.x, >5.x.x, >6.0-dev (compatible))</strong> with support for the database you intend to use.</li>
148 <li>getimagesize() function need to be enabled.</li>
149 <li>These optional presence of the following modules within PHP will provide access to additional features, but they are not required.
150 <ul>
151 <li>zlib Compression support</li>
152 <li>Remote FTP support</li>
153 <li>XML support</li>
154 <li>Imagemagick support</li>
155 <li>GD Support</li>
156 </ul>
157 </li>
158 </ul>

175
176 <div class="content">
177
178 <p>Installation of phpBB3 will vary according to your server and database. If you have <em>shell access</em> to your account (via telnet or ssh for example) you may want to upload the entire phpBB3 archive (in binary mode!) to a directory on your host and unarchive it there.</p>
179
180 <p>If you do not have shell access or do not wish to use it you will need to decompress the phpBB3 archive to a local directory on your system using your favourite compression program, e.g. winzip, rar, zip, etc. From there you must FTP <strong>ALL</strong> the files it contains (being sure to retain the directory structure and filenames) to your host. Please ensure that the cases of filenames are retained, do <strong>NOT</strong> force filenames to all lower or upper case doing so will cause errors later.</p>
181
182 <p>All .php, .inc, .sql, .cfg, .html and .txt files should be uploaded in <strong>ASCII</strong> mode, while all graphics should be uploaded in <strong>BINARY</strong> mode. If you are unfamiliar with what this means please refer to your FTP client documentation. In most cases this is all handled transparantly by your ftp client but if you encounter problems later you should be sure the files where uploaded correctly as described here.</p>
183
184 <p>phpBB3 comes supplied with english as its standard language. However a number of separate packs for different languages are available. If you are not a native english speaker you may wish to install one or more of these packages before continuing. The installation process below will allow you to select a default language from those available (you can of course change this default at a later stage). For more details of language packs, where to obtain them and how to install them please see the <a href="README.html#i18n">README</a>.</p>
185
186 <p>Once all the files have been uploaded to your site you should point your browser at this location with the addition of <code>install/</code>. For example if your domain name is <em>www.mydomain.tld</em> and you placed phpBB3 in a directory /phpBB3 off your web root you would enter <em>http://www.mydomain.tld/phpBB3/install/</em> or (alternatively) <em>http://www.mydomain.tld/phpBB3/install/index.php</em> into your browser. When you have done this you should see the phpBB3 Installation screen appear.</p>
187
188 <h4>Introduction:</h4>
189
190 <p>The installation screen gives you a short introduction into phpBB. It allows you to read the license phpBB3 is released under (General Public License) and provides information about how you can receive support. To start the installation, use the <em>Install</em> button.</p>
191
192 <h4>Requirements</h4>
193
194 <p>The first page you will see after starting the installation is the Requirements list. phpBB3 checks automatically whether everything that it needs to run properly is installed on your server. You need to have at least the minimum PHP version installed, and at least one database available to continue the installation. Also important, is that all shown folders are available and do have the correct permissions. Please see the description of each section to find out whether they are optional or required for phpBB3 to run. If everything is in order, you can continue the installation with <em>Start Install</em>.</p>
195
196 <h4>Database settings</h4>
197
198 <p>You now have to decide which database to use. See the <a href="#require">Requirements section</a> for information on which databases are supported. If you do not know your database settings, please contact your host and ask for them. You will not be able to continue without them. You need:</p>
199
200 <ul>
201 <li>The Database Type - the database you will be using.</li>
202 <li>The Database server hostname or DSN - the address of the database server.</li>
203 <li>The Database server port - the port of the database server (most of the time this is not needed).</li>
204 <li>The Database name - the name of the database on the server.</li>
205 <li>The Database username and Database password - the login data to access the database.</li>
206 </ul>
207
208 <div class="indent">
209 <p><strong>Note:</strong> if you are installing using SQLite, you should enter the full path to your database file in the DSN field and leave the username and password fields blank. For security reasons, you should make sure that the database file is not stored in a location accessible from the web.</p>
210 </div>
211
212 <p>You don't need to change the Prefix for tables in database setting, unless you plan on using multipe phpBB installations on one database. In this case you can use a different prefix for each installation to make it work.</p>
213
214 <p>After you entered your details, you can continue with the Proceed to next step button. Now phpBB3 will check whether the data you entered will lead to a successful database connection and whether tables with the same prefix already exist.</p>
215
216 <p>A <em>Could not connect to the database</em> error means that you didn't enter the database data correctly and it is not possible for phpBB to connect. Make sure that everything you entered is in order and try again. Again, if you are unsure about your database settings, please contact your host.</p>
217
218 <p>If you installed another version of phpBB before on the same database with the same prefix, phpBB will inform you and you just need to enter a different database prefix.</p>
219
220 <p>If you see the Successful Connection message, you can continue to the next step.</p>
221
222 <h4>Administrator details</h4>
223
224 <p>Now you have to create your administration user. This user will have full administration access and he/she will be the first user on your forum. All fields on this page are required. You can also set the default language of your forum on this page. In a vanilla phpBB3 installation we only include English. You can download further languages from <a href="http://www.phpbb.com/">www.phpbb.com</a>, and add them before installing or later.</p>
225
226 <h4>Configuration file</h4>
227
228 <p>In this step, phpBB will try to write the configuration file automatically. The forum needs the configuration to run properly. It contains all database settings, so without it, phpBB will not be able to access the database.</p>
229
230 <p>Usually writing the configuration file automatically works fine. But in some cases it can fail due to wrong file permissions, for instance. In this case, you need to upload the file manually. phpBB asks you to download the config.php file and tells you what to do with it. Please read the instructions carefully. After you have uploaded the file, use <em>Done</em> to get to the last step. If <em>Done</em> returns you to the same page as before, and does not return a success message, you did not upload the file correctly.</p>
231
232 <h4>Advanced settings</h4>
233
234 <p>The Advanced settings allow you to set some parameters of the board configuration. They are optional, and you can always change them later. So if you are not sure what these settings mean, proceed to the final step and finish the installation.</p>
235
236 <p>If the installation was successful, you can now use the Login button to visit the Administration Control Panel. Congratulations, you have installed phpBB3 successfully. But there is still work ahead!</p>
237
238 <p>If you are unable to get phpBB3 installed even after reading this guide, please look at the support section to find out where you can ask for further assistance.</p>
239
240 <p>At this point if you are converting from phpBB 2.0.x, you should refer to the <a href="#convert">conversion steps</a> for further information. If not, you should remove the install directory from your server as you will only be able to access the Administration Control Panel whilst it is present.</p>

252
253 <div class="paragraph">
254 <div class="inner"><span class="corners-top"><span></span></span>
255
256 <div class="content">
257
258 <p>If you are currently using a stable release of phpBB3 updating to this version is straightforward. You would have downloaded one of four packages and your choice determines what you need to do. <strong>Please Note</strong>: That before updating we heavily recommend you do a <em>full backup of your database and existing phpBB3 files</em>! If you are unsure how to achieve this please ask your hosting provider for advice.</p>
259
260 <p><strong>Please make sure you update your phpBB3 source files too, even if you run the <code>database_update.php</code> file.</strong></p>
261
262 <a name="update_full"></a><h3>4.i. Full package</h3>
263
264 <p>The full package is normally meant for new installations only, but if you want to replace all source files this package comes in handy.</p>
265
266 <p>First you should make a copy of your existing <em>config.php</em> file, keep it in a safe place! Next delete all the existing phpBB3 files, you may want to leave your <code>files/</code> and <code>images/</code> directory in place. You can leave alternative styles in-place too. With this complete you can upload the new phpBB3 files (see <a href="#install">New installation</a> for details if necessary). Once complete copy back your saved <em>config.php</em>, replacing the new one. Another method is to just <strong>replace</strong> the existing files with the files from the full package - though make sure you do <strong>not</strong> overwrite your config.php file.</p>
267
268 <p>You should now run <code>install/database_update.php</code> which, depending on your previous version, will make a number of database changes. You may receive <em>FAILURES</em> during this procedure, they should not be a cause for concern unless you see an actual <em>ERROR</em>, in which case the script will stop (in this case you should seek help via our forums or bug tracker).</p>
269
270 <p>Once the install/database_update.php has completed you may proceed to the Administration Control Panel and check remove the install directory as advised.</p>
271
272 <a name="update_files"></a><h3>4.ii. Changed files only</h3>
273
274 <p>This package is meant for those wanting to only replace changed files from a previous version to the latest version. This package normally contains the changed files from up to five previous versions.</p>
275
276 <p>This package contains a number of archives, each contains the files changed from a given release to the latest version. You should select the appropriate archive for your current version, e.g. if you currently have <samp>3.0.0</samp> you should select the phpBB-3.0.0_to_3.0.1.zip/tar.gz file.</p>
277
278 <p>The directory structure has been preserved enabling you (if you wish) to simply upload the contents of the archive to the appropriate location on your server, i.e. simply overwrite the existing files with the new versions. Do not forget that if you have installed any MODs these files will overwrite the originals possibly destroying them in the process. You will need to re-add MODs to any affected file before uploading.</p>
279
280 <p>As for the other update procedures you should run <b>install/database_update.php</b> after you have finished updating the files. This will update your database schema and increment the version number.</p>
281
282 <a name="update_patch"></a><h3>4.iii. Patch file</h3>
283
284 <p>The patch file package is for those wanting to update through the patch application, and being compfortable with it.</p>
285
286 <p>The patch file is one solution for those with many Modifications (MODs) or other changes who do not want to re-add them back to all the changed files if they use the method explained above. To use this you will need command line access to a standard UNIX type <strong>patch</strong> application. If you do not have access to such an application but still want to use this update approach, we strongly recommend the <a href="update_auto">Automatic update package</a> explained below. It is also the preferred update method.</p>
287
288 <p>A number of patch files are provided to allow you to update from previous stable releases. Select the correct patch, e.g. if your current version is 3.0.0 you need the phpBB-3.0.0_to_3.0.1.patch file. Place the correct patch in the parent directory containing the phpBB3 core files (i.e. index.php, viewforum.php, etc.). With this done you should run the following command: <strong>patch -cl -d [PHPBB DIRECTORY] -p1 < [PATCH NAME]</strong> (where PHPBB DIRECTORY is the directory name your phpBB Installation resides in, for example phpBB3, and where PATCH NAME is the relevant filename of the selected patch file). This should complete quickly, hopefully without any HUNK FAILED comments.</p>
289
290 <p>If you do get failures you should look at using the <a href="#update_files">Changed files only</a> package to replace the files which failed to patch, please note that you will need to manually re-add any Modifications (MODs) to these particular files. Alternatively if you know how you can examine the .rej files to determine what failed where and make manual adjustments to the relevant source.</p>
291
292 <p>You should of course delete the patch file (or files) after use. As for the other update procedures you should run <code>install/database_update.php</code> after you have finished updating the files. This will update your database schema and data (if appropriate) and increment the version number.</p>
293
294 <a name="update_auto"></a><h3>4.iv. Automatic update package</h3>
295
296 <p>This update method is the preferred method for updating. This package allows detecting changed files automatically and merges changes if needed.</p>
297
298 <p>The automatic update package is holding - contrary to the others - only the update informations for updating the last released version to the latest available version. These package is meant for use with the automatic update tool.</p>
299
300 <p>To perform the update, either follow the instructions from the <code>Administration Control Panel->System</code> Tab - this should point out that you are running an outdated version and will guide you through the update - or follow the instructions listed below.</p>
301
302 <ul>
303 <li>Go to the <a href="http://www.phpbb.com/downloads/">downloads page</a> and download the latest update package listed there, matching your current version.</li>
304 <li>Upload the archives contents to your phpBB installation - only the install folder is required. Upload the whole install folder, retaining the file structure.</li>
305 <li>After the install folder is present, phpBB3 will go offline automatically.</li>
306 <li>Point your browser to the install directory, for example <samp>http://www.example.com/phpBB3/install/</samp></li>
307 <li>Choose the "Update" Tab and follow the instructions</li>
308 </ul>
309
310 <p> </p>
311
312 <a name="update_all"></a><h3>4.v. All package types</h3>
313
314 <p>If you have non-English language packs installed you may want to see if a new version has been made available. A number of missing strings may have been added which, though not essential, may be beneficial to users. Please note that at this time not all language packs have been updated so you should be prepared to periodically check for updates.</p>

329
330 <div class="content">
331
332 <p>This paragraph explains the steps necessary to convert your existing phpBB2 installation to phpBB3.</p>
333
334 <a name="prereq"></a><h3>5.i. Requirements before converting</h3>
335
336 <p>Before converting we heavily recommend you do a <em>full backup of your database and files</em>! If you are unsure how to achieve this please ask your hosting provider for advice. You basically need to follow the basic instructions given for <a href="#install">New installations</a>. Please <strong>do not</strong> overwrite any old files - install phpBB3 at a different location.</p>
337
338 <p>Once you made a backup of everything and also have a brand new phpBB3 installation, you can now begin the conversion.</p>
339
340 <p>Note that the conversion requires CREATE and DROP privileges for the phpBB3's database user account.</p>
341
342 <a name="conversion"></a><h3>5.ii. Converting</h3>
343
344 <p>To begin the conversion visit the install folder of your phpBB3 installation (the same as you have done for installing). Now you will see a new tab <em>Convert</em>. Click this tab.</p>
345
346 <p>As with install the conversion is automated. Your previous 2.0.x database tables will not be changed as well as the original 2.0.x files remaining unaltered. The conversion is actually only filling your phpBB3 database tables and copying additional data over to your phpBB3 installation. This has the benefit that if something goes wrong you are able to either re-run the conversion or continue a conversion, while your old board is still accessible. We really recommend you disable your old installation while converting, else you may have inconsistent data after the conversion.</p>
347
348 <p>Please note that this conversion process may take quite some time and depending on your hosting provider this may result in it failing (due to web server or other timeout issues). If this is the case you should ask your provider if they are willing to allow the convert script to temporarily exceed their limits (be nice and they will probably be quite helpful).</p>
349
350 <p>Once completed your board should be immediately available. If you encountered errors you should report the problems to our bug tracker or seek help via our forums (see <a href="README.html">README</a> for details).</p>

352 <a name="postreq"></a><h3>5.iii. Things to do after conversion</h3>
353
354 <p>After successful conversion there may be a few items you need to do - apart from checking if the installation is accessible and everything displayed correctly.</p>
355
356 <p>The first thing you may want to do is going to the administration control panel and checking every configuration item within the general tab. Thereafter you may want to adjust the forum descriptions/names if you entered HTML there. You also may want to access the other administrative sections, e.g. adjusting permissions, smilies, icons, ranks, etc.</p>
357
358 <p>Within the conversion the search index has not been created or transferred. This means after conversion you are not able to find any matches if you want to search for something. We recommend you rebuild your search index within <code>Admin -> Maintenance -> Database -> Search Index</code>.</p>
359
360 <p>After verifying the settings in the ACP, you can delete the install directory to enable the board. The board will stay disabled until you do so.</p>
361
362 <p>Once you are pleased with your new installation you may want to give it the name of your old installation, changing the directory name. With phpBB3 this is possible without any problems - but you may still want to check your cookie settings within the administration panel, if the cookie path need to be adjusted prior to renaming.</p>
363
364 <a name="convprob"></a><h3>5.iv. Common conversion problems</h3>
365
366 <p><strong>Broken non-latin characters</strong> The conversion script assumes that the database encoding in the source phpBB2 matches the encoding defined in the <code>lang_main.php</code> file of the default language pack of the source installation. Edit that file to match the database's encoding and re-start the conversion procedure.</p>
367
368 <p><strong>http 500 / white pages</strong> The conversion is a load-heavy procedure. Restrictions imposed by some server hosting providers can cause problems. The most common causes are: too low values for the php settings <code>memory_limit</code> and <code>max_execution_time</code>. Limits on the allowed CPU time are also a frequent cause for such errors, as are caps on the number of database queries allowed. If you cannot change such settings, then contact your hosting provider or run the conversion procedure on a different computer. The phpBB.com forums are also an excellent location to ask for support.</p>
369
370 <p><strong>Password conversion</strong> Due to the utf-8 based handling of passwords in phpBB3, it is not always possible to transfer all passwords. For passwords "lost in translation" the easiest workaround is to use the "forgotten password" function.</p>
371
372 <p><strong>Path to your former board</strong> The converter expects the relative path to your old board's files. So, -for instance - if the new board is located at <code>http://www.yourdomain.com/forum</code> and the phpBB3 is located at <code>http://www.yourdomain.com/phpBB3</code>, then the correct value would be <code>../forum</code>. Note that the webserver user must be able to access the source installation's files.</p>
373
374 <p><strong>Missing images</strong> If your default board language's language pack does not include all images, then some images might be missing in your installation. Always use a complete language pack as default language.</p>
375
376 <p><strong>Smilies</strong> During the conversion you might see warnings about image files where the copying failed. That can happen if the old board's smilies have the same file names as those on the new board. Copy those files manually after the conversion, if you want to continue using the old smilies.</p>

395 <p>Once you have successfully installed phpBB3 you <strong>MUST</strong> ensure you remove the entire install/ directory. Leaving the install directory in place is a <em>very serious potential security issue</em> which may lead to deletion or alteration of files, etc. Please note that until this directory is removed, phpBB3 will not operate and a warning message will be displayed. Beyond this <strong>essential</strong> deletion, you may also wish to delete the docs/ directories if you wish.</p>
396
397 <p>With these directories deleted you should proceed to the administration panel. Depending on how the installation completed you may have been directed there automatically. If not, login as the administrator you specified during install/conversion and click the <strong>Administration Panel</strong> link at the bottom of any page. Ensure that details specified in <code>Admin -> General</code> are correct!</p>
398
399 <a name="avatars"></a><h3>6.i. Uploadable avatars</h3>
400
401 <p>phpBB3 supports several methods for allowing users to select their own <em>avatar</em> (an avatar is a small image generally unique to a user and displayed just below their username in posts).</p>
402
403 <p>Two of these options allow users to upload an avatar from their machine or a remote location (via a URL). If you wish to enable this function you should first ensure the correct paths for uploadeable avatars is set in <code>Admin -> General -> Board Configuration -> Avatar settings</code>. By default this is <em>images/avatars/uploads</em> but you can set it to whatever you like, just ensure the configuration setting is updated. You must also ensure this directory can be written to by the webserver. Usually this means you have to alter its permissions to allow anyone to read and write to. Exactly how you should do this depends on your ftp client or server operating system.</p>
404
405 <p>On UNIX systems for example you set the directory to a+rwx (or ugo+rwx or even 777). This can be done from a command line on your server using chmod or via your FTP client (using the Change Permissions, chmod or other Permissions dialoge box, see your FTP clients documentation for help). Most FTP clients list permissions in the form of User (Read, Write, Execute), Group (Read, Write, Execute) and Other (Read, Write, Execute). You need to tick all of these boxes to set correct permissions.</p>
406
407 <p>On Windows system you need to ensure the directory is not write-protected and that it has global write permissions (see your servers documentation or contact your hosting provider if you are unsure on how to achieve this).</p>
408
409 <p>Please be aware that setting a directories permissions to global write access is a potential security issue. While it is unlikely that anything nasty will occur (such as all the avatars being deleted) there are always people out there to cause trouble. Therefore you should monitor this directory and if possible make regular backups.</p>
