5 This document is a part of the TYPO3 project. TYPO3 is an open source web
6 content management system released under the GNU GPL. TYPO3 is copyright
7 (c) 1999-2009 by Kasper Skaarhoj.
9 This document describes the system requirements for TYPO3 and the installation
10 routine.
13 ===============================================================================
14 System requirements
15 ===============================================================================
17 TYPO3 requires a web server with a PHP installation and a database. While TYPO3
18 can be configured to run on many web servers with different databases, this
19 document assumes that Apache and MySQL will be used. This document does not
20 cover using TYPO3 with other databases or web servers.
22 The following configuration is the minimum required:
23 - a web server capable of running PHP
24 - PHP 5.3.0 or newer with the following extensions:
25 - filter
26 - GD2
27 - JSON
28 - mysql
29 - pcre
30 - session
31 - SPL
32 - SOAP
33 - standard
34 - xml
35 - zlib
36 Some extensions can be optionally compiled into PHP. A list of loaded
37 extensions can be checked using the phpinfo() function.
38 - memory_limit set to at least 64M in php.ini
39 - MySQL 5.0 or newer
40 - 200 MB of disk space
41 - AllowOverride in the Apache configuration includes "Indexes" and "FileInfo"
42 (see FAQ below)
44 The following configuration is recommended:
45 - Apache 2.x
46 - mod_expires and mod_rewrite enabled in the Apache configuration
47 - PHP 5.3.0 or newer with the following extensions:
48 - cURL
49 - filter
50 - GD2
51 - hash
52 - JSON
53 - mbstring
54 - mysql
55 - pcre
56 - session
57 - SOAP
58 - SPL
59 - standard
60 - xml
61 - zlib
62 Some extensions can be optionally compiled into PHP. A list of loaded
63 extensions can be checked using the phpinfo() function.
64 - Safe mode is not supported, thus it must not be activated
65 - memory_limit set to 128M or more in php.ini
66 - MySQL 5.1 or newer
67 - GraphicsMagick or ImageMagick v6 or newer
68 - 200 MB or more of disk space
69 - AllowOverride in the Apache configuration includes "Indexes" and "FileInfo"
70 (see FAQ below)
72 TYPO3 uses /dev/urandom or /dev/random on Unix-like platforms for security
73 purposes. Access to these files is highly recommended and increases TYPO3
74 security. Make sure to add "/dev/random:/dev/urandom" to open_basedir
75 settings if you use it. If these paths are unavailable, TYPO3 will attempt to
76 simulate random number generation. This is less secure, causes performance
77 issues and warnings in the TYPO3 system log.
79 ===============================================================================
80 Obtaining TYPO3
81 ===============================================================================
83 To get TYPO3, navigate to the following location:
84 http://typo3.org/download/packages/
86 TYPO3 consists of two packages: source and dummy. The source package contains
87 files that are the same for every TYPO3 web site. The dummy package contains
88 files unique to each TYPO3 installation.
90 To install TYPO3, both packages must be downloaded.
93 ===============================================================================
94 Installation: simple (not recommended!)
95 ===============================================================================
97 This procedure is not recommended because it makes upgrades harder. However, it
98 can be the only option if you hosting company does not provide SSH access to
99 the web server.
101 To install TYPO3, unpack the source package locally. Unpacking will produce a
102 directory with a name like typo3_src-x.y.z, where x, y and z correspond to the
103 TYPO3 version. For example, the TYPO3 x.y.z source package will create a
104 directory named typo3_src-x.y.z.
106 Next unpack the dummy package. This will create a directory with the name
107 dummy-x.y.z. Now create a new directory and copy all files and folders from
108 within typo3_src-x.y.z and dummy-x.y.z into this new directory.
110 Use a FTP or SFTP program or any other available way to upload all files to
111 the web server.
113 Change permissions of the directories and files. The following directories and
114 files should be read-only for the web server:
115 t3lib/
116 typo3/
117 index.php
119 All other directories should be writable for the web server. If in doubt,
120 contact your hosting company and ask them to assist in adjusting permissions.
123 ===============================================================================
124 Installation: recommended
125 ===============================================================================
127 To install TYPO3, unpack the source package outside of the web site root
128 directory on your server. The location must be accessible to the web server.
129 Unpacking will produce a directory with a name like typo3_src-x.y.z, where x,
130 y and z correspond to the TYPO3 version. For example, the TYPO3 4.3.0 source
131 package will create a directory named typo3_src-4.3.0.
133 Unpack the dummy package in the temporary location on the server. This will
134 create a dummy-x.y.z directory. Move all files and directories from the
135 dummy-x.y.z directory to the web site root directory.
137 Linux, Unix and Mac OS X users should use the tar.gz packages and unpack them
138 using:
139 tar xzf source-x.y.z
140 tar xzf dummy-x.y.z
142 Windows users can use Windows built-in unpacker on unpack ZIP versions of
143 packages.
145 On Linux, Unix or Mac OS X systems create a symbolic link named typo3_src
146 pointing to the source package:
147 ln -s /var/www/typo3_src-4.3.0 /var/www/example.com/typo3_src
149 On Windows Vista or Windows 7 create a symbolic link named typo3_src
150 pointing to the source package:
151 mklink /D C:\<dir>\typo3_src-4.3.0 C:\<dir>\example.com\typo3_src
153 Users of Windows XP/2000 can use the "junction" program by Marc Russinovich to
154 create links. The program can be obtained at:
155 http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx
157 Next create links for the typo3/ and t3lib/ directories:
158 cd /var/www/example.com
159 ln -s typo3_src/t3lib
160 ln -s typo3_src/typo3
162 Linux, Unix and Mac OS X users also create a symbolic link to index.php
163 ln -s typo3_src/index.php
165 Windows users must copy index.php from the source directory to the web site
166 root directory because Windows does not support links for files.
168 Change permissions and ownership of the directories. This usually requires the
169 "sudo" command. Assuming that the web server user is in the group named
170 "apache", execute the following commands in the web site root directory:
171 sudo chgrp -R apache fileadmin typo3temp typo3conf uploads
172 sudo chmod -R g+rwX,o-w fileadmin typo3temp typo3conf uploads
174 If "sudo" is not available, ask your hosting company to change the permissions.
177 ===============================================================================
178 Setting up TYPO3
179 ===============================================================================
181 To set up TYPO3, navigate to your web site. The TYPO3 installer will run in the
182 1-2-3 mode to easily guide you through the installation.
185 ===============================================================================
186 Troubleshooting
187 ===============================================================================
189 For troubleshooting read the FAQ below. If your problem is not listed, feel
190 free to ask questions in the TYPO3 mailing lists:
191 http://typo3.org/community/mailing-lists/
194 ===============================================================================
195 FAQ
196 ===============================================================================
198 Q: Why do I get "500 Server error" when I navigate to my TYPO3 web site
199 immediately after installation?
200 A: Make sure that AllowOverride allows "Indexes" and "FileInfo" in the Apache
201 configuration. If you cannot ensure this, rename .htaccess files to
202 _.htaccess. TYPO3 will run but considerably slower.
203 Here is the list of the files to rename:
204 typo3/contrib/.htaccess
205 typo3/gfx/.htaccess
206 typo3/mod/user/ws/.htaccess
207 typo3/sysext/.htaccess
208 typo3/sysext/t3skin/stylesheets/.htaccess
209 If the error does not disappear, web server error logs should help. For
210 Apache, the error log is usually located in /var/log/apache2 or
211 /var/log/httpd. Check with your hosting provider if you are in doubt where
212 the logs are located.
214 Q: Backend or Installer looks strange, no images just black and white?
215 A: Maybe you missed some configuration in your .htaccess file.
216 Have a look at typo3_src/misc/advanced.htaccess to find the options
217 you might need.
219 Q: I went through the setup process and created an admin user. Why can't I log
220 in now?
221 A: If you use MySQL 5.x or newer, try setting it to "compatible" mode. Open the
222 TYPO3 Install tool under http://example.com/typo3/install/ (where example.com
223 is the web site domain), navigate to "All configuration". find "setDBinit",
224 and add this line to the top of the input field:
225 SET SESSION sql_mode='MYSQL40'
227 Q: What do I have to do regarding security?
228 A: You have to make sure that you keep your TYPO3-core and the extensions
229 up to date.
230 * Subscribe to the announcement mailing list. This will inform you about new
231 releases of the TYPO3 core and security bulletins of core and community
232 extensions.
