TYPO3 is an open source PHP based web content management system released under the GNU GPL. TYPO3 is copyright (c) 1999-2013 by Kasper Skaarhoj.
This document describes:
- System requirements for TYPO3
- Installation routine
- Upgrade routine
The TYPO3 backend is accessed through a web browser. TYPO3 CMS 6.2 LTS supports the following web browsers:
- Internet Explorer 8 and later
- Google Chrome (Windows, MacOS, Linux)
- Firefox (Windows, MacOS, Linux)
- Safari on MacOS
- and other compatible modern browsers
TYPO3 requires a web server with a PHP environment and a database. The minimum system requirements for running TYPO3 CMS 6.2 LTS are:
- Webserver capable of running PHP applications (Apache, Nginx, IIS or other)
- PHP >5.3.7 up to 5.5 (PHP 5.4 or later recommended)
- MySQL 5.1 up to 5.6 or compatible (no "strict mode", see below)
- more than 200 MB of disk space
TYPO3 works with MySQL in the above mentioned versions. It will also work on compatible "drop-in" replacements like MariaDB or Percona.
Note that MySQL "strict mode" is currently not supported by TYPO3. If your MySQL server is configured with either STRICT_TRANS_TABLES or STRICT_ALL_TABLES (especially true with MySQL 5.6, as this is a new default), you need to configure setDBinit in the Install Tool. See question 2 in the "Installation FAQ" below for more information.
- memory_limit set to at least 64M
- max_execution_time set to at least 30s (240s recommended)
- register_globals disabled
- disabled safe_mode (not supported)
- disabled magic_quotes (not supported)
- AllowOverride in the Apache configuration includes "Indexes" and "FileInfo" (see FAQ below)
Your PHP needs to support the following extensions. Install will check if these are available.
-
These are usually part of the standard PHP package on most distributions:
- fileinfo
- filter
- hash
- openssl
- pcre
- session
- soap
- SPL
- standard
- xml
- zip
- zlib
-
These might have to be installed separately:
- gd
- json
- mysqli
There are plenty of possible setups for high performance TYPO3 installations (i.e. using Varnish Cache, Nginx, PHP-FPM, etc). Consider this resource for more ideas or suggestions: http://wiki.typo3.org/Performance_tuning
This is a basic recommended setup for best performance and increased functionality:
-
Apache with mod_expires and mod_rewrite enabled
-
MySQL 5.5 or newer
-
GraphicsMagick or ImageMagick v6 or newer installed on the server
-
PHP
- version 5.4 or later
- memory_limit set to at least 128M
- max_execution_time set to at least 240s
-
Additional PHP extensions:
- PHP opcode cache, i.e.: apc, xcache, eaccelerator, Zend Optimizer, Zend OPcache, wincache (in case of an IIS installation)
- apc caching (with at least 100 MB of memory available)
- curl
- mbstring
- FreeType (usually included within the PHP distribution)
- bcmath or gmp (needed if you'd like to use the openid system extension)
-
PHP access to /dev/urandom or /dev/random on Unix-like platforms for increased security. Make sure to add "/dev/random:/dev/urandom" to open_basedir settings if you use it. If these paths are unavailable, TYPO3 will attempt to simulate random number generation. This is less secure, reduces performance and throws out warnings in the TYPO3 system log.
-
TYPO3 works with PHP's IPv6 support, which is enabled by default since PHP 5.3. If you compile PHP 5.3 on your own, be aware not to use option "--disable-ipv6", because this will break the IPv6 support and the according unit tests.
It is not possible to upgrade any version below 4.5 LTS to 6.2 LTS directly, since some upgrade wizards are not available anymore on 6.2 LTS.
It is highly recommended to upgrade to 4.5 LTS first and continue with a second upgrade to 6.2 LTS.
If you have SSH access to your webserver and are able to create symlinks, this is the recommended way of setting up TYPO3 so that it can easily be upgraded later through the Install Tool:
- Uncompress the
typo3_src-6.2.x.tar.gz
file one level above the Document Root of your Web server:
/var/www/site/htdocs/ $ cd ..
/var/www/site/ $ tar xzf typo3_src-6.2.x.tar.gz
- Create the symlinks in your Document Root:
cd htdocs
ln -s ../typo3_src-6.2.x typo3_src
ln -s typo3_src/index.php index.php
ln -s typo3_src/typo3 typo3
- In case you use Apache, copy the .htaccess to your Document Root:
cp typo3_src/_.htaccess .htaccess
You end up with the follow structure of files:
typo3_src-6.2.x/
htdocs/typo3_src -> ../typo3_src-6.2.x/
htdocs/typo3 -> typo3_src/typo3/
htdocs/index.php -> typo3_src/index.php
htdocs/.htaccess
This allows you to upgrade TYPO3 later by simply replacing the symlink with a newer version, or by using the integrated "Core Updater" which can be found in the Install Tool.
On Windows Vista and Windows 7, you can create symbolic links using
the mklink
tool:
mklink /D C:\<dir>\example.com\typo3_src C:\<dir>\typo3_src-6.2.x
Users of Windows XP/2000 or newer can use the junction
program by
Marc Russinovich to create links. It can be downloaded at
http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx
Windows users might need to copy index.php
from the source directory to the
web site root directory in case the Windows version does not support links
for files.
TYPO3 Core upgrades through the Install Tool is not supported under Windows.
In case you only have FTP or SFTP access to your hosting environment, you can still install TYPO3, but you won't easily be able to upgrade your installation once a new patchlevel release is out.
Please note that this is not a recommended setup!
- Uncompress
typo3_src-6.2.x.tar.gz
locally - Upload all files and subdirectories directly in your Document Root (where files that are served by your webserver are located).
- In case your provider uses Apache:
- rename
_.htaccess
to.htaccess
- rename
You end up with this files in your Document Root:
.htaccess

Now access the web server using a web browser. You will be redirected to the Install Tool which will walk you through the steps for setting up TYPO3 for the first time.
It will check if your environment conforms to the minimum system requirements and gives you some suggestions on what to change in case there are any discrepancies.
The Install Tool will create the required directory structure for you (typo3conf, uploads, fileadmin, typo3temp).
Former versions of TYPO3 required the download of a "Dummy Package" (or "Blank Package"). This is no longer required since version 6.2!
To ensure a secure installation, you have to make sure that you keep your TYPO3 core and the extensions up to date.
-
Subscribe to the announcement mailing list. This will inform you about new releases of the TYPO3 core and security bulletins of core and community extensions. http://lists.typo3.org/cgi-bin/mailman/listinfo/typo3-announce
-
Use the scheduler task "Update Extension List (em)" to update the list of available extensions regularly. You should check regularly, if new versions of these extensions are available and apply these updates.

Q: Why do I get "500 Server error" when I navigate to my TYPO3 web site immediately after installation?
A: If you are using Apache web server, check the Apache error log for specifics on the error. The cause might be some missing module, or some syntax error in your .htaccess file. The error log is usually located in /var/log/apache2 or /var/log/httpd. Check with your hosting provider if you are in doubt where the logs are located.
Q: I went through the setup process and created an admin user. Why can't I log in now?
A: If you use MySQL 5.x or newer, try setting it to "compatible" mode. Open the TYPO3 Install Tool under http://example.com/typo3/install/ (where example.com is the web site domain), navigate to "All configuration". Find "setDBinit", and add this line to the top of the input field:
SET SESSION sql_mode=''
Q: Some modules or extensions make Apache crash on Windows. What is the cause?
A: Fluid uses complex regular expressions which require a lot of stack space during the first processing. On Windows the default stack size for Apache is a lot smaller than on unix. You can increase the size to 8MB (default on unix) by adding to the httpd.conf:
<IfModule mpm_winnt_module>
ThreadStackSize 8388608
</IfModule>
Restart Apache after this change.
