INSTALLING TYPO3 ================ 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 Client browser support ---------------------- 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 Server system requirements -------------------------- 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 ### MySQL environment 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. ### PHP environment * 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) ### 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: * fileinfo * filter * hash * openssl * pcre * 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 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) * 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. Installation ------------ ### 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-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. ### Windows specifics On Windows Vista and Windows 7, you can create symbolic links using the `mklink` tool: ``` mklink /D C:\
