INSTALLING TYPO3

TYPO3 is an open source PHP based web content management system released under the GNU GPL. TYPO3 is copyright (c) 1999-2016 by Kasper Skaarhoj.

This document describes:

  • System requirements for TYPO3
  • Installation routine
  • Upgrade routine

Client browser support

The TYPO3 backend is accessed through a web browser. TYPO3 v8 supports the following web browsers:

  • Internet Explorer 11 and later
  • Microsoft Edge
  • Google Chrome (Windows, MacOS X, Linux)
  • Firefox (Windows, MacOS X, Linux)
  • Safari on MacOS X
  • and other compatible modern browsers

Server system requirements

TYPO3 requires a web server with a PHP environment and a database. The minimum system requirements for running TYPO3 v8 are:

  • Webserver capable of running PHP applications (Apache, Nginx, IIS or other)
  • PHP 7
  • MySQL 5.5 up to 5.7 or compatible
  • more than 200 MB of disk space

Note: If you use any other webserver than Apache, make sure you add the necessary configuration normally provided in the various .htaccess files inside the TYPO3 core. This configuration is security relevant, therefore only experienced server administrators should create such configuration.

MySQL environment

TYPO3 works with MySQL in the above mentioned versions. It will also work on compatible "drop-in" replacements like MariaDB or Percona. The InnoDB engine is required to be enabled.

MySQL required privileges

The MySQL user needs a least the following privileges on the TYPO3 database:

  • SELECT, INSERT, UPDATE, DELETE
  • CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES

It is recommended to also grant the following privileges:

  • CREATE VIEW, SHOW VIEW
  • EXECUTE, CREATE ROUTINE, ALTER ROUTINE

PHP environment

  • memory_limit set to at least 64M
  • max_execution_time set to at least 30 (240 seconds recommended)
  • AllowOverride in the Apache configuration includes "Indexes" and "FileInfo" (see FAQ below)

PHP required extensions

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:

    • filter
    • hash
    • openssl
    • pcre >= 8.30
    • session
    • soap
    • SPL
    • standard
    • xml
    • zip
    • zlib
  • These might have to be installed separately:

    • gd
    • json
    • mysqli

Recommended setup

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 7.0 or later
    • memory_limit set to at least 128M
    • max_execution_time set to at least 240
    • max_input_vars set to at least 1500
  • Additional PHP extensions:

    • PHP opcode cache, i.e.: apc, xcache, eaccelerator, Zend Optimizer, wincache (in case of an IIS installation)
    • apcu caching (with at least 100 MB of memory available)
    • curl
    • mbstring
    • FreeType 2 (usually included within the PHP distribution)
    • bcmath or gmp (needed if you'd like to use the openid system extension)
    • fileinfo (mandatory for proper file type detection)
  • 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. If you compile PHP on your own, be aware not to use option "--disable-ipv6", because this will break the IPv6 support and the according unit tests.

Installation

Important note for upgrades from TYPO3 CMS versions below 7 LTS

It is not possible to upgrade any version below 7 LTS to 8 directly, since some upgrade wizards are not available anymore on 8.

It is highly recommended to upgrade to 7 LTS first and continue with a second upgrade to 8.

If SSH and symlinks are possible

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-8.x.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-8.x.x.tar.gz
  • Important: If you use GIT to fetch the sources, don't forget to run the following commands, otherwise your installation won't work!
cd typo3_src
composer install --no-dev
cd ..
  • Create the symlinks in your Document Root:
  cd htdocs
  ln -s ../typo3_src-8.x.x typo3_src
  ln -s typo3_src/index.php
  ln -s typo3_src/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-8.x.x/
  htdocs/typo3_src -> ../typo3_src-8.x.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.

Windows specifics

On Windows Vista and newer you can create symbolic links using the mklink tool:

  mklink /D C:\<dir>\example.com\typo3_src C:\<dir>\typo3_src-8.x.x
  mklink C:\<dir>\example.com\index.php C:\<dir>\typo3_src-8.x.x\index.php

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.

No SSH and symlinks possible (not recommended)

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 patch-level release is out.

Please note that this is not a recommended setup!

  • Uncompress typo3_src-8.x.x.zip 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 the file _.htaccess to .htaccess.

You end up with this files in your Document Root:

 .htaccess
 ChangeLog
 GPL.txt
 index.php
 INSTALL.md
 LICENSE.txt
 NEWS.txt
 README.md
 typo3/

Installation: further steps

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).

TYPO3 Security

To ensure a secure installation, you have to make sure that you keep your TYPO3 core and the extensions up to date.

Installation FAQ

1

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.

2

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=''

3

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.
