  • Trac Install

    v3 v4  
    44Trac 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.
    55
    6 Since 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.

    10 What 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 [trac:TracInstallPlatforms 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.

    65 It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database.
     57Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.

    6759=== Optional Dependencies
    … …  
    7264 * [http://subversion.apache.org/ Subversion], 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings. 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.
    7365
    74 There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. (Good luck finding precompiled SWIG bindings for any Windows package at that listing. TracSubversion points you to [http://alagazam.net Algazam], which works for me under Python 2.6.)

    7567
    7668Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    7769
    78 
    7970'''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].

    8777A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.

    116 '''Attention''': The various available versions of these dependencies are not necessarily interchangeable, 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] or [trac:IrcChannel].
    117 
    118 Please 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!).

    121110== Installing Trac ==
    122111=== Using `easy_install`
    123 One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    124 With setuptools you can install Trac from the Subversion repository;

    126114A few examples:
    … …  
    159147All commands (`tracd`, `trac-admin`) are available in `/opt/user/trac/bin`. This can also be leveraged for `mod_python` (using `PythonHandler` directive) and `mod_wsgi` (using `WSGIDaemonProcess` directive)
    160148
    161 Additionally, you can install several Trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.

    164150
    165151=== From source
    166 Of course, using the python-typical setup at the top of the source directory also works.
    167 
    168 You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. `Trac-1.0.tar.gz`), or you can get the source directly from the repository (see [trac:SubversionRepository] for details).

    176160This will byte-compile the Python source code and install it as an .egg file or folder in the `site-packages` directory
    … …  
    206190The 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.

    209192== Creating a Project Environment ==
    210193
    211 A [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.

    212195
    213196A new environment is created using [wiki:TracAdmin trac-admin]:
    … …  
    225208Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    226209
    227 When selecting the location of your environment, make sure that the filesystem on which the environment directory resides supports sub-second timestamps (i.e. **not** `ext2` or `ext3` on Linux), as the modification time of the `conf/trac.ini` file will be monitored to decide whether an environment restart is needed or not. A too coarse-grained timestamp resolution may result in inconsistencies in Trac < 1.0.2 (though the best advice is to opt for a platform with sub-second timestamp resolution when possible regardless of the version of Trac you are running).

    228211
    229212Finally, 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:
