4 TYPO3 is an open source PHP based web content management system released
5 under the GNU GPL. TYPO3 is copyright (c) 1999-2013 by Kasper Skaarhoj.
7 This document describes:
9 * System requirements for TYPO3
10 * Installation routine
13 Client browser support
14 ----------------------
16 The TYPO3 backend is accessed through a web browser. TYPO3 CMS 6.2 LTS
17 supports the following web browsers:
19 * Internet Explorer 8 and later
20 * Google Chrome (Windows, MacOS, Linux)
21 * Firefox (Windows, MacOS, Linux)
23 * and other compatible modern browsers
25 Server system requirements
26 --------------------------
28 TYPO3 requires a web server with a PHP environment and a database. The minimum
29 system requirements for running TYPO3 CMS 6.2 LTS are:
31 * Webserver capable of running PHP applications (Apache, Nginx, IIS or other)
32 * PHP >5.3.7 up to 5.5 (PHP 5.4 or later recommended)
33 * MySQL 5.1 up to 5.6 or compatible (no "strict mode", see below)
34 * more than 200 MB of disk space
38 TYPO3 works with MySQL in the above mentioned versions. It will also work on
39 compatible "drop-in" replacements like MariaDB or Percona.
41 Note that MySQL "strict mode" is currently not supported by TYPO3. If your
42 MySQL server is configured with either STRICT_TRANS_TABLES or
43 STRICT_ALL_TABLES (especially true with MySQL 5.6, as this is a new default),
44 you need to configure setDBinit in the Install Tool. See question 2 in the
45 "Installation FAQ" below for more information.
49 * memory_limit set to at least 64M
50 * max_execution_time set to at least 30s (240s recommended)
51 * register_globals disabled
52 * disabled safe_mode (not supported)
53 * disabled magic_quotes (not supported)
54 * AllowOverride in the Apache configuration includes "Indexes" and "FileInfo"
57 ### PHP required extensions
59 Your PHP needs to support the following extensions. Install will
60 check if these are available.
62 * These are usually part of the standard PHP package on most distributions:
76 * These might have to be installed separately:
83 There are plenty of possible setups for high performance TYPO3 installations
84 (i.e. using Varnish Cache, Nginx, PHP-FPM, etc). Consider this resource for
85 more ideas or suggestions: http://wiki.typo3.org/Performance_tuning
87 This is a basic recommended setup for best performance and increased
90 * Apache with mod_expires and mod_rewrite enabled
94 * GraphicsMagick or ImageMagick v6 or newer installed on the server
97 * version 5.4 or later
98 * memory_limit set to at least 128M
99 * max_execution_time set to at least 240s
101 * Additional PHP extensions:
102 * PHP opcode cache, i.e.: apc, xcache, eaccelerator, Zend Optimizer,
103 Zend OPcache, wincache (in case of an IIS installation)
104 * apc caching (with at least 100 MB of memory available)
107 * FreeType (usually included within the PHP distribution)
108 * bcmath or gmp (needed if you'd like to use the openid system extension)
110 * PHP access to /dev/urandom or /dev/random on Unix-like platforms for
111 increased security. Make sure to add "/dev/random:/dev/urandom" to
112 open_basedir settings if you use it. If these paths are unavailable, TYPO3
113 will attempt to simulate random number generation. This is less secure,
114 reduces performance and throws out warnings in the TYPO3 system log.
116 * TYPO3 works with PHP's IPv6 support, which is enabled by default since
117 PHP 5.3. If you compile PHP 5.3 on your own, be aware not to use option
118 "--disable-ipv6", because this will break the IPv6 support and the according
124 ### If SSH and symlinks are possible
126 If you have SSH access to your webserver and are able to create symlinks,
127 this is the recommended way of setting up TYPO3 so that it can easily
128 be upgraded later through the Install Tool:
130 * Uncompress the `typo3_src-6.2.x.tar.gz` file one level above the Document
131 Root of your Web server:
133 /var/www/site/htdocs/ $ cd ..
134 /var/www/site/ $ tar xzf typo3_src-6.2.x.tar.gz
137 * Create the symlinks in your Document Root:
140 ln -s ../typo3_src-6.2.x typo3_src
141 ln -s typo3_src/index.php index.php
142 ln -s typo3_src/typo3 typo3
145 * In case you use Apache, copy the .htaccess to your Document Root:
147 cp typo3_src/_.htaccess .htaccess
150 You end up with the follow structure of files:
154 htdocs/typo3_src -> ../typo3_src-6.2.x/
155 htdocs/typo3 -> typo3_src/typo3/
156 htdocs/index.php -> typo3_src/index.php
160 This allows you to upgrade TYPO3 later by simply replacing the symlink
161 with a newer version, or by using the integrated "Core Updater" which can
162 be found in the Install Tool.
164 ### Windows specifics
166 On Windows Vista and Windows 7, you can create symbolic links using
169 mklink /D C:\<dir>\example.com\typo3_src C:\<dir>\typo3_src-6.2.x
172 Users of Windows XP/2000 or newer can use the `junction` program by
173 Marc Russinovich to create links. It can be downloaded at
174 http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx
176 Windows users might need to copy `index.php` from the source directory to the
177 web site root directory in case the Windows version does not support links
180 TYPO3 Core upgrades through the Install Tool is not supported under
183 ### No SSH and symlinks possible (not recommended)
185 In case you only have FTP or SFTP access to your hosting environment, you
186 can still install TYPO3, but you won't easily be able to upgrade your
187 installation once a new patchlevel release is out.
189 Please note that this is not a recommended setup!
191 * Uncompress `typo3_src-6.2.x.tar.gz` locally
192 * Upload all files and subdirectories directly in your Document Root
193 (where files that are served by your webserver are located).
194 * In case your provider uses Apache:
195 * rename `_.htaccess` to `.htaccess`
197 You end up with this files in your Document Root:
211 Installation: further steps
212 ---------------------------
214 Now access the web server using a web browser. You will be redirected to the
215 Install Tool which will walk you through the steps for setting up TYPO3 for
218 It will check if your environment conforms to the minimum system requirements
219 and gives you some suggestions on what to change in case there are any
222 The Install Tool will create the required directory structure for you
223 (typo3conf, uploads, fileadmin, typo3temp).
225 Former versions of TYPO3 required the download of a "Dummy Package"
226 (or "Blank Package"). This is no longer required since version 6.2!
231 To ensure a secure installation, you have to make sure that you keep your
232 TYPO3 core and the extensions up to date.
234 * Subscribe to the announcement mailing list. This will inform you about new
235 releases of the TYPO3 core and security bulletins of core and community
237 http://lists.typo3.org/cgi-bin/mailman/listinfo/typo3-announce
239 * Use the scheduler task "Update Extension List (em)" to update the list of
240 available extensions regularly. You should check regularly, if new versions
241 of these extensions are available and apply these updates.
243 * Please refer to official TYPO3 Security Guide for further information
244 about security-related topics of TYPO3 CMS and the resources compiled by
246 http://docs.typo3.org/typo3cms/SecurityGuide/

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