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
section 2 below.

1. Decompress the phpBB3 archive to a local directory on your system.
2. Upload all the files contained in this archive (retaining the
   directory structure) to a web accessible directory on your server or
   hosting account.
3. Change the permissions on config.php to be writable by all (666 or -rw-rw-rw- within your FTP Client)
4. Change the permissions on the following directories to be writable by all (777 or -rwxrwxrwx within your FTP Client):
   
   store/, cache/, files/ and images/avatars/upload/.
5. 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.
6. Click the INSTALL tab, follow the steps and fill out all the requested information.
7. Change the permissions on config.php to be writable only by yourself (644 or -rw-r--r-- within your FTP Client)
8. phpBB3 should now be available, please MAKE SURE you read at least Section 6 below for important, security related post-installation instructions.

If you experienced problems or do not know how to proceed with any of the steps above please read the rest of this document.

phpBB3 has a few requirements which must be met before you are able to install and use it.

• A webserver or web hosting account running on any major Operating System with support for PHP
• A SQL database system, one of:
  
  • MySQL 3.23 or above (MySQLi supported)
  • PostgreSQL 7.3+
  • SQLite 2.8.2+
  • Firebird 2.1+
  • MS SQL Server 2000 or above (directly or via ODBC)
  • Oracle
  
  
• PHP 4.3.3+ (>=4.3.3, >4.4.x, >5.x.x, >6.0-dev (compatible)) with support for the database you intend to use.
• getimagesize() function need to be enabled.
• These optional presence of the following modules within PHP will
  provide access to additional features, but they are not required.
  
  • zlib Compression support
  • Remote FTP support
  • XML support
  • Imagemagick support
  • GD Support
  
  

If your server or hosting account does not meet the requirements above we are afraid phpBB3 is not for you.

Installation of phpBB3 will vary according to your server and database. If you have shell access
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.

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 ALL 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 NOT force filenames to all lower or upper case doing so will cause errors later.

All .php, .inc, .sql, .cfg, .html and .txt files should be uploaded in ASCII mode, while all graphics should be uploaded in BINARY
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.

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 README.

Once all the files have been uploaded to your site you should point your browser at this location with the addition of install/. For example if your domain name is www.mydomain.tld and you placed phpBB3 in a directory /phpBB3 off your web root you would enter http://www.mydomain.tld/phpBB3/install/ or (alternatively) http://www.mydomain.tld/phpBB3/install/index.php into your browser. When you have done this you should see the phpBB3 Installation screen appear.

Introduction:

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 Install button.

Requirements

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 Start Install.

Database settings

You now have to decide which database to use. See the Requirements section
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:

• The Database Type - the database you will be using.
• The Database server hostname or DSN - the address of the database server.
• The Database server port - the port of the database server (most of the time this is not needed).
• The Database name - the name of the database on the server.
• The Database username and Database password - the login data to access the database.

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.

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.

A Could not connect to the database 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.

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.

If you see the Successful Connection message, you can continue to the next step.

Administrator details

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 www.phpbb.com, and add them before installing or later.

Configuration file

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.

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 Done to get to the last step. If Done returns you to the same page as before, and does not return a success message, you did not upload the file correctly.

Advanced settings

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.

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!

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.

At this point if you are converting from phpBB 2.0.x, you should refer to the conversion steps
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.

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. Please Note: That before updating we heavily recommend you do a full backup of your database and existing phpBB3 files! If you are unsure how to achieve this please ask your hosting provider for advice.

Please make sure you update your phpBB3 source files too, even if you run the database_update.php file.

4.i. Full package

The full package is normally meant for new installations only, but
if you want to replace all source files this package comes in handy.

First you should make a copy of your existing config.php file, keep it in a safe place! Next delete all the existing phpBB3 files, you may want to leave your files/ and images/ directory in place. You can leave alternative styles in-place too. With this complete you can upload the new phpBB3 files (see New installation for details if necessary). Once complete copy back your saved config.php, replacing the new one. Another method is to just replace the existing files with the files from the full package - though make sure you do not overwrite your config.php file.

You should now run install/database_update.php which, depending on your previous version, will make a number of database changes. You may receive FAILURES during this procedure, they should not be a cause for concern unless you see an actual ERROR, in which case the script will stop (in this case you should seek help via our forums or bug tracker).

Once the install/database_update.php has completed you may proceed
to the Administration Control Panel and check remove the install
directory as advised.

4.ii. Changed files only

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.

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 3.0.6 you should select the phpBB-3.0.6_to_3.0.7-PL1.zip/tar.gz file.

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.

As for the other update procedures you should run install/database_update.php after you have finished updating the files. This will update your database schema and increment the version number.

4.iii. Patch file

The patch file package is for those wanting to update through the patch application, and being comfortable with it.

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 patch
application. If you do not have access to such an application but still
want to use this update approach, we strongly recommend the Automatic update package explained below. It is also the recommended update method.

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 3.0.5 you need the phpBB-3.0.6_to_3.0.7-PL1.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: patch -cl -d [PHPBB DIRECTORY] -p1 < [PATCH NAME]
(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.

If you do get failures you should look at using the Changed files only
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.

You should of course delete the patch file (or files) after use. As for the other update procedures you should run install/database_update.php
after you have finished updating the files. This will update your
database schema and data (if appropriate) and increment the version
number.

4.iv. Automatic update package

This update method is the recommended method for updating. This
package allows detecting changed files automatically and merges changes
if needed.

The automatic update package contains - contrary to the others -
only the information required to update the previous release version to
the latest available version. These packages are meant for use with the
automatic update tool.

To perform the update, either follow the instructions from the Administration Control Panel->System
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.

• Go to the downloads page and download the latest update package listed there, matching your current version.
• Upload the archives contents to your phpBB installation - only the
  install folder is required. Upload the whole install folder, retaining
  the file structure.
• After the install folder is present, phpBB3 will go offline automatically.
• Point your browser to the install directory, for example http://www.example.com/phpBB3/install/
• Choose the "Update" Tab and follow the instructions

4.v. All package types

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.

This paragraph explains the steps necessary to convert your existing phpBB2 installation to phpBB3.

5.i. Requirements before converting

Before converting we heavily recommend you do a full backup of your database and files!
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 New installations. Please do not overwrite any old files - install phpBB3 at a different location.

Once you made a backup of everything and also have a brand new phpBB3 installation, you can now begin the conversion.

Note that the conversion requires CREATE and DROP privileges for the phpBB3's database user account.

5.ii. Converting

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 Convert. Click this tab.

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.

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).

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 README for details).

5.iii. Things to do after conversion

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.

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.

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 Admin -> Maintenance -> Database -> Search Index.

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.

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.

5.iv. Common conversion problems

Broken non-latin characters The conversion script assumes that the database encoding in the source phpBB2 matches the encoding defined in the lang_main.php
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.

http 500 / white pages 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 memory_limit and max_execution_time.
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.

Password conversion 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.

Path to your former board The converter expects the relative path to your old board's files. So, - for instance - if the old board is located at http://www.yourdomain.com/forum and the phpBB3 installation is located at http://www.yourdomain.com/phpBB3, then the correct value would be ../forum. Note that the webserver user must be able to access the source installation's files.

Missing images 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.

Smilies 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.

Once you have successfully installed phpBB3 you MUST ensure you remove the entire install/ directory. Leaving the install directory in place is a very serious potential security issue
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 essential deletion, you may also wish to delete the docs/ directories if you wish.

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 Administration Panel link at the bottom of any page. Ensure that details specified in Admin -> General are correct!

6.i. Uploadable avatars

phpBB3 supports several methods for allowing users to select their own avatar (an avatar is a small image generally unique to a user and displayed just below their username in posts).

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 Admin -> General -> Board Configuration -> Avatar settings. By default this is images/avatars/uploads
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.

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.

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).

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.
