    45Trac is written in the Python programming language and needs a database, [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL], or [http://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://genshi.edgewall.org Genshi] templating system.
    56
    6 What follows are generic instructions for installing and setting up Trac and its requirements. While you can find instructions for installing Trac on specific systems at TracInstallPlatforms on the main Trac site, please be sure to '''first read through these general instructions''' to get a good understanding of the tasks involved.
    7 
    8 == Short - Install a released version ==
    9 For the quick install, make sure you have [http://python.org Python-2.5], [http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install easy_install] and SQlite-3.3.4 installed (or above).
    10 {{{
    11 sudo easy_install Trac==0.11
    12 }}}
    13 
    14 == Requirements - also older versions possible ==
    15 
     7Since version 0.12, Trac can also be localized, and there's probably a translation available for your language. If you want to be able to use the Trac interface in other languages, then make sure you have installed the optional package [#OtherPythonPackages Babel]. Pay attention to the extra steps for localization support in the [#InstallingTrac Installing Trac] section below. Lacking Babel, you will only get the default english version, as usual.
     8
     9If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at ["TracL10N"].

     11What follows are generic instructions for installing and setting up Trac and its requirements. While you may find instructions for installing Trac on specific systems at TracInstallPlatforms on the main Trac site, please be sure to '''first read through these general instructions''' to get a good understanding of the tasks involved.
     12
     13
     14== Prerequisites ==
     15=== Mandatory Prerequisites
    1616To install Trac, the following software packages must be installed:
    1717
    18  * [http://www.python.org/ Python], version >= 2.3
    19    * if using mod_python together with xml-related things, use python-2.5. expat is namespaced there and does not cause apache to crash any more(see [http://www.dscpl.com.au/wiki/ModPython/Articles/ExpatCausingApacheCrash here] for details).
    20    * For RPM-based systems you might also need the `python-devel` and `python-xml` packages.
    21    * See instructions in ["TracOnWindows/Python2.5"]
     18 * [http://www.python.org/ Python], version >= 2.4 (we dropped the support for Python 2.3 in this release)
    2219 * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6
    23  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.4.1
    24  * You also need a database system and the corresponding python drivers for it.
    25    The database can be either SQLite, PostgreSQL or ''MySQL (experimental)''.
    26  * optional if some plugins require it: [http://www.clearsilver.net/ ClearSilver]
    27 
    28 === For SQLite ===
    29 
    30  * [http://www.sqlite.org/ SQLite], version 3.3.4 and above preferred.
    31  * If not using Python-2.5: [http://pysqlite.org/ PySQLite], version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x), version 2.3.2 preferred. For details see PySqlite
    32 
    33 ''Note: It appears that PySQLite 2.x is required for Trac 0.9+/SQLite 3.x if you plan to use the 'trac-post-commit-hook.py' script available from the 'contrib' section of the source repository.''
    34 
    35 ''Note: Users of Mac OS X please take care; the Apple-supplied SQLite contains additional code to support file locking on network filesystems like AFP or SMB. This is not presently (3.3.6) in the mainline sources, so if you build your own SQLite from source it will not function correctly on such filesystems - typically it gives the error "{{{database is locked}}}". [http://www.alastairs-place.net/2006/07/sqlite_and_mac/ A patch] is available for version 3.3.6, based on Apple's code, otherwise you're probably best off using the Apple supplied version (presently 3.1.3).''
    36 
    37 === For PostgreSQL ===
    38 
     20 * [http://genshi.edgewall.org/wiki/Download Genshi], [genshi:source:trunk trunk], from svn, minimum required revision is [G1072], current [G1092] works fine as well.
     21
     22You also need a database system and the corresponding python bindings.
     23The database can be either SQLite, PostgreSQL or MySQL.
     24
     25==== For the SQLite database #ForSQLite
     26
     27If you're using Python 2.5 or 2.6, you already have everything you need.
     28
     29If you're using Python 2.4 and need pysqlite, you can download from
     30[http://code.google.com/p/pysqlite/downloads/list google code] the Windows
     31installers or the tar.gz archive for building from source:
     32{{{
     33$ tar xvfz <version>.tar.gz
     34$ cd <version>
     35$ python setup.py build_static install
     36}}}
     37 
     38That way, the latest SQLite version will be downloaded and built into the
     39bindings.
     40
     41SQLite 2.x is no longer supported. For SQLite 3.x, the pysqlite 1.1.x
     42bindings are also no longer supported, use pysqlite 2.x.
     43
     44See additional information in [trac:PySqlite PySqlite].
     45
     46==== For the PostgreSQL database #ForPostgreSQL
     47
     48You need to install the database and its Python bindings:
    3949 * [http://www.postgresql.org/ PostgreSQL]
    40  * [http://initd.org/projects/psycopg2 psycopg2] or [http://pypgsql.sourceforge.net/ pyPgSQL]
    41 
    42 '''Warning''': PostgreSQL 8.3 uses a strict type checking mechanism. To use Trac with the 8.3 Version of PostgreSQL, you will need [http://trac.edgewall.org/changeset/6512 trac-0.11] or later.
    43 
    44 === For MySQL ===
    45 
    46 '''Warning''': MySQL support is currently ''still'' experimental. That means it works for some people, but several issues remain, in particular regarding the use of unicode and the key length in the repository cache. See MySqlDb for more detailed information.
    47 
    48  * [http://mysql.com/ MySQL], version 4.1 or later
    49  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later
    50 
    51 === Optional Requirements ===
     50 * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     51
     52See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     53
     54
     55==== For the MySQL database #ForMySQL
     56
     57Trac can now work quite well with MySQL, provided you follow the guidelines.
     58
     59 * [http://mysql.com/ MySQL], version 5.0 or later
     60 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
     61
     62It is '''very''' important to read carefully the  [trac:MySqlDb MySqlDb] page before creating the database.
     63
     64=== Optional Prerequisites
    5265
    5366==== Version Control System ====
    5467
    55 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently not supported.
    56 
    57  * [http://subversion.tigris.org/ Subversion], version >= 1.0. (versions recommended: 1.2.4, 1.3.2 or 1.4.2) and the '''''corresponding''''' Python bindings. For troubleshooting, check TracSubversion
    58    * Trac uses the [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 SWIG] bindings included in the Subversion distribution, '''not''' [http://pysvn.tigris.org/ PySVN] (which is sometimes confused with the standard SWIG bindings).
    59    * If Subversion was already installed without the SWIG bindings, on Unix you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`.
    60    * There are [http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 pre-compiled bindings] available for win32.
    61  * Support for other version control systems is provided via third-parties. See PluginList and VersioningSystemBackend.
     68===== Subversion =====
     69 * [http://subversion.apache.org/ Subversion], 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings. Actually older versions starting from 1.0, like 1.2.4, 1.3.2 or 1.4.2, etc. should still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page/
     70
     71There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings
     72
     73
     74'''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
     75
     76
     77===== Others =====
     78
     79Support for other version control systems is provided via third-parties. See [trac:PluginList PluginList] and [trac:VersioningSystemBackend VersioningSystemBackend].
    6280
    6381==== Web Server ====
    64  * A CGI-capable web server (see TracCgi), or
     82 * A CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
     83   is highly discouraged''', better use one of the following options,
    6584 * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or
    66  * [http://httpd.apache.org/ Apache] with [http://code.google.com/p/modwsgi/ mod_wsgi] (see [wiki:TracModWSGI])
    67     * This should work with Apache 1.3, 2.0 or 2.2 and promises to deliver more performance than using mod_python. A little less mature than mod_python.
    68  * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython)
    69     * When installing mod_python the development versions of Python and Apache are required (actually the libraries and header files)
    70 
    71 For those stuck with Apache 1.3, it is also possible to get Trac working with [http://www.modpython.org/ mod_python 2.7] (see [wiki:TracModPython2.7 TracModPython2.7]). This guide hasn't been updated since 0.84, so it may or may not work.
    72 
    73 ==== Other Python Utilities ====
    74  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 for WikiRestructuredText.
    75  * [http://pygments.pocoo.org Pygments] for [wiki:TracSyntaxColoring syntax highlighting], also [http://silvercity.sourceforge.net/ SilverCity] and/or [http://gnu.org/software/enscript/enscript.html Enscript] may still be used.
    76     * Note that !SilverCity 0.9.6 has a [http://sourceforge.net/tracker/index.php?func=detail&aid=1424436&group_id=45693&atid=443739 bug] that breaks Python syntax highlighting in Trac. Until an update is made available, we recommend using version 0.9.5.
    77  * [http://pytz.sf.net pytz] to get a complete list of time zones, otherwise Trac will fall back on a shorter list from an internal time zone implementation.
    78 
    79 '''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the MailingList or IrcChannel.
    80 
    81 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [wiki:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there ''probably concern older versions of Trac than the one you're installing'' (there are even some pages that are still talking about Trac 0.8!).
     85 * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
     86   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp]), or
     87 * [http://httpd.apache.org/ Apache] with
     88   - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and
     89     http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac
     90   - [http://modpython.org/ mod_python 3.3.1], see TracModPython)
     91   
     92
     93==== Other Python Packages ====
     94
     95 * [http://babel.edgewall.org Babel], version >= 0.9.4,
     96   needed for localization support
     97 * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9
     98   for WikiRestructuredText.
     99 * [http://pygments.pocoo.org Pygments] for
     100   [wiki:TracSyntaxColoring syntax highlighting].
     101   [http://silvercity.sourceforge.net/ SilverCity] and/or
     102   [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
     103   but are deprecated and you really should be using Pygments.
     104 * [http://pytz.sf.net pytz] to get a complete list of time zones,
     105   otherwise Trac will fall back on a shorter list from
     106   an internal time zone implementation.
     107
     108'''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the [trac:MailingList MailingList] or [trac:IrcChannel IrcChannel].
     109
     110Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [trac:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there ''probably concern older versions of Trac than the one you're installing'' (there are even some pages that are still talking about Trac 0.8!).
     111
    82112
    83113== Installing Trac ==
     
    85115One way to install Trac is using `setuptools`.
    86116With setuptools you can install Trac from the subversion repository; for example,
    87 to install release version 0.11b2 do:
    88 {{{
    89 easy_install http://svn.edgewall.org/repos/trac/tags/trac-0.11b2
     117to install release version 0.12dev do:
     118{{{
     119easy_install http://svn.edgewall.org/repos/trac/trunk
    90120}}}
    91121
     
    94124$ python ./setup.py install
    95125}}}
    96 
    97 ''Note: you'll need root permissions or equivalent for this step.''
     126See SubversionRepository for details about getting the source.
     127
     128''Note 1: you'll need root permissions or equivalent for this step.'' [[br]]
     129''Note 2: installing from source is the preferred method if you want to have a localized version of Trac'' [[br]]
    98130
    99131This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
     
    102134The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server.
    103135
     136If you want to make Trac available in other languages, make sure you have installed Babel and then run this additional step before doing the `install` (or simply redo the `install` afterwards):
     137{{{
     138$ python ./setup.py compile_catalog -f
     139}}}
     140(the `-f` flag is needed as long as some translations are marked ''fuzzy'', i.e. incomplete, which will most probably be the case during the whole development period, as  strings are continuously added or modified)
     141
     142
    104143=== Advanced Options ===
    105144
     
    119158easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    120159}}}
     160Note: If installing on Mac OS X 10.6 running {{{ easy_install http://svn.edgewall.org/repos/trac/trunk }}} will install into /usr/local and /Library/Python/2.6/site-packages by default
    121161
    122162The above will place your `tracd` and `trac-admin` commands into `/usr/local/bin` and will install the Trac libraries and dependencies into `/Library/Python/2.5/site-packages`, which is Apple's preferred location for third-party Python application installations.
    123163
     164
    124165== Creating a Project Environment ==
    125166
    126 A [wiki:TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable configuration file and various other files and directories.
     167A [TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable [TracIni configuration file], and various other files and directories.
    127168
    128169A new environment is created using [wiki:TracAdmin trac-admin]:
     
    131172}}}
    132173
    133 [wiki:TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project, the type and the path to an existing [wiki:TracEnvironment#SourceCodeRepository source code repository], the [wiki:TracEnvironment#DatabaseConnectionStrings database connection string], and so on. If you're not sure what to specify for one of these options, just leave it blank to use the default value. The database connection string in particular will always work as long as you have SQLite installed. Leaving the path to the source code repository empty will disable any functionality related to version control, but you can always add that back when the basic system is running.
    134 
    135 Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file.
    136 
    137 ''Note: The user account under which the web server runs will require write permissions to the environment directory and all the files inside.  On Linux, with the web server running as user apache and group apache, enter:''
    138 
    139   chown -R apache.apache /path/to/myproject
    140 
     174[TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for one of these options, just press `<Enter>` to use the default value.
     175
     176Leaving the database connection string empty in particular will always work as long as you have SQLite installed.
     177For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     178
     179Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterward, or the version control support can be disabled completely if you don't need it.
     180
     181Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
     182
     183Finally, make sure the user account under which the web front-end runs will have '''write permissions''' to the environment directory and all the files inside. This will be the case if you run `trac-admin ... initenv` as this user. If not, you should set the correct user afterwards. For example on Linux, with the web server running as user `apache` and group `apache`, enter:
     184{{{
     185# chown -R apache.apache /path/to/myproject
     186}}}

    152198}}}
    153199
    154 
    155200== Running Trac on a Web Server ==
    156201
    157202Trac provides three options for connecting to a "real" web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python.
    158203
    159 If you're not afraid of running development code, you can also try running Trac on [wiki:TracModWSGI mod_wsgi]. This should deliver even better performance than mod_python, but the module is not considered stable just yet.
     204
     205Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS.
     206
     207==== Generating the Trac cgi-bin directory ====
     208
     209In order for Trac to function properly with FastCGI or mod_python, you need to have a trac.cgi file. This is an executable which loads the appropriate Python code. It can be generated using the `deploy` option of [wiki:TracAdmin trac-admin].
     210
     211There is, however, a bit of a chicken-and-egg problem. The [wiki:TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this:
     212{{{
     213mkdir -p /usr/share/trac/projects/my-project
     214trac-admin /usr/share/trac/projects/my-project initenv
     215trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
     216mv /tmp/deploy/* /usr/share/trac
     217}}}
     218
     219==== Setting up the Plugin Cache ====
     220
     221Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the PYTHON_EGG_CACHE environment variable. Refer to your server documentation for detailed instructions.
