4 TYPO3 is an open source PHP based web content management system released
5 under the GNU GPL. TYPO3 is copyright (c) 1999-2015 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 7
17 supports the following web browsers:
19 * Internet Explorer 9 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 7 are:
31 * Webserver capable of running PHP applications (Apache, Nginx, IIS or other)
33 * MySQL 5.5 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 5.5 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 2 (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 on your own, be aware not to use option
118 "--disable-ipv6", because this will break the IPv6 support and the according
124 ### Important note for upgrades from TYPO3 CMS versions **below 6.2 LTS**
126 It is not possible to upgrade any version below 6.2 LTS to 7 directly,
127 since some upgrade wizards are not available anymore on 7.
129 It is highly recommended to upgrade to 6.2 LTS first and continue with
130 a second upgrade to 7.
132 ### If SSH and symlinks are possible
134 If you have SSH access to your webserver and are able to create symlinks,
135 this is the recommended way of setting up TYPO3 so that it can easily
136 be upgraded later through the Install Tool:
138 * Uncompress the `typo3_src-7.0.x.tar.gz` file one level above the Document
139 Root of your Web server:
141 /var/www/site/htdocs/ $ cd ..
142 /var/www/site/ $ tar xzf typo3_src-7.0.x.tar.gz
145 * Create the symlinks in your Document Root:
148 ln -s ../typo3_src-7.0.x typo3_src
149 ln -s typo3_src/index.php index.php
150 ln -s typo3_src/typo3 typo3
153 * In case you use Apache, copy the .htaccess to your Document Root:
155 cp typo3_src/_.htaccess .htaccess
158 You end up with the follow structure of files:
162 htdocs/typo3_src -> ../typo3_src-7.0.x/
163 htdocs/typo3 -> typo3_src/typo3/
164 htdocs/index.php -> typo3_src/index.php
168 This allows you to upgrade TYPO3 later by simply replacing the symlink
169 with a newer version, or by using the integrated "Core Updater" which can
170 be found in the Install Tool.
172 ### Windows specifics
174 On Windows Vista and Windows 7, you can create symbolic links using
177 mklink /D C:\<dir>\example.com\typo3_src C:\<dir>\typo3_src-7.0.x
180 Users of Windows XP/2000 or newer can use the `junction` program by
181 Marc Russinovich to create links. It can be downloaded at
182 http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx
184 Windows users might need to copy `index.php` from the source directory to the
185 web site root directory in case the Windows version does not support links
188 TYPO3 Core upgrades through the Install Tool is not supported under
191 ### No SSH and symlinks possible (not recommended)
193 In case you only have FTP or SFTP access to your hosting environment, you
194 can still install TYPO3, but you won't easily be able to upgrade your
195 installation once a new patchlevel release is out.
197 Please note that this is not a recommended setup!
199 * Uncompress `typo3_src-7.0.x.tar.gz` locally
200 * Upload all files and subdirectories directly in your Document Root
201 (where files that are served by your webserver are located).
202 * In case your provider uses Apache:
203 * rename `_.htaccess` to `.htaccess`
205 You end up with this files in your Document Root:
219 Installation: further steps
220 ---------------------------
222 Now access the web server using a web browser. You will be redirected to the
223 Install Tool which will walk you through the steps for setting up TYPO3 for
226 It will check if your environment conforms to the minimum system requirements
227 and gives you some suggestions on what to change in case there are any
230 The Install Tool will create the required directory structure for you
231 (typo3conf, uploads, fileadmin, typo3temp).
233 Former versions of TYPO3 required the download of a "Dummy Package"
234 (or "Blank Package"). This is no longer required since version 6.2!
239 To ensure a secure installation, you have to make sure that you keep your
240 TYPO3 core and the extensions up to date.
242 * Subscribe to the announcement mailing list. This will inform you about new
243 releases of the TYPO3 core and security bulletins of core and community
245 http://lists.typo3.org/cgi-bin/mailman/listinfo/typo3-announce
247 * Use the scheduler task "Update Extension List (em)" to update the list of
248 available extensions regularly. You should check regularly, if new versions
249 of these extensions are available and apply these updates.
251 * Please refer to official TYPO3 Security Guide for further information
252 about security-related topics of TYPO3 CMS and the resources compiled by
254 http://docs.typo3.org/typo3cms/SecurityGuide/
255 http://typo3.org/teams/security/resources/
261 Q: Why do I get "500 Server error" when I navigate to my TYPO3 web site
262 immediately after installation?
264 A: If you are using Apache web server, check the Apache error log for specifics
265 on the error. The cause might be some missing module, or some syntax error
266 in your .htaccess file. The error log is usually located in /var/log/apache2
267 or /var/log/httpd. Check with your hosting provider if you are in doubt
268 where the logs are located.
271 Q: I went through the setup process and created an admin user. Why can't I log
274 A: If you use MySQL 5.x or newer, try setting it to "compatible" mode. Open the
275 TYPO3 Install Tool under http://example.com/typo3/install/ (where
276 example.com is the web site domain), navigate to "All configuration".
277 Find "setDBinit", and add this line to the top of the input field:
279 SET SESSION sql_mode=''
283 Q: Some modules or extensions make Apache crash on Windows. What is the cause?
285 A: Fluid uses complex regular expressions which require a lot of stack space
286 during the first processing. On Windows the default stack size for Apache
287 is a lot smaller than on unix. You can increase the size to 8MB (default on
288 unix) by adding to the httpd.conf:
290 <IfModule mpm_winnt_module>
291 ThreadStackSize 8388608
294 Restart Apache after this change.
