Trac Installation Guide for 0.12dev
Table of Contents
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 Babel. Pay attention to the extra steps for localization support in the Installing Trac section below. Lacking Babel, you will only get the default english version, as usual.
If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at TracL10N.
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 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.
To install Trac, the following software packages must be installed:
- Python, version ≥ 2.4 (we dropped the support for Python 2.3 in this release)
- setuptools, version ≥ 0.6
- Genshi, trunk, from svn, minimum required revision is [G1072], current [G1092] works fine as well.
You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
For the SQLite database
If you're using Python 2.5 or 2.6, you already have everything you need.
If you're using Python 2.4 and need pysqlite, you can download from google code the Windows installers or the tar.gz archive for building from source:
$ tar xvfz <version>.tar.gz $ cd <version> $ python setup.py build_static install
That way, the latest SQLite version will be downloaded and built into the bindings.
SQLite 2.x is no longer supported. For SQLite 3.x, the pysqlite 1.1.x bindings are also no longer supported, use pysqlite 2.x.
See additional information in PySqlite.
For the PostgreSQL database
You need to install the database and its Python bindings:
See DatabaseBackend for details.
For the MySQL database
Trac can now work quite well with MySQL, provided you follow the guidelines.
It is very important to read carefully the MySqlDb page before creating the database.
Version Control System
- 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 TracSubversion page/
Please note: if using Subversion, Trac must be installed on the same machine. Remote repositories are currently not supported.
- A CGI-capable web server (see TracCgi), but usage of Trac as a cgi script is highly discouraged, better use one of the following options,
- a FastCGI-capable web server (see TracFastCgi), or
- an AJP-capable web server (see TracOnWindowsIisAjp), or
- Apache with
Other Python Packages
- Babel, version ≥ 0.9.4, needed for localization support
- docutils, version ≥ 0.3.9 for WikiRestructuredText.
- Pygments for syntax highlighting. SilverCity and/or Enscript may still be used but are deprecated and you really should be using Pygments.
- pytz to get a complete list of time zones, otherwise Trac will fall back on a shorter list from an internal time zone implementation.
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.
Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the 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!).
One way to install Trac is using
With setuptools you can install Trac from the subversion repository; for example,
to install release version 0.12dev do:
But of course the python-typical setup at the top of the source directory also works:
$ python ./setup.py install
See SubversionRepository for details about getting the source.
Note 1: you'll need root permissions or equivalent for this step.
Note 2: installing from source is the preferred method if you want to have a localized version of Trac
This will byte-compile the python source code and install it as an .egg file or folder in the
of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
If 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
$ python ./setup.py compile_catalog -f
-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)
To install Trac to a custom location, or find out about other advanced installation options, run:
Also see Installing Python Modules for detailed information.
Specifically, you might be interested in:
or, if installing Trac to a Mac OS X system:
easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
Note: 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
The above will place your
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.
Creating a Project Environment
A 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.
A new environment is created using trac-admin:
$ trac-admin /path/to/myproject initenv
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 source code repository, the 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.
Also note that the values you specify here can be changed later by directly editing the TracIni configuration file.
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:
chown -R apache.apache /path/to/myproject
Running the Standalone Server
After having created a Trac environment, you can easily try the web interface by running the standalone server tracd:
$ tracd --port 8000 /path/to/myproject
Then, fire up a browser and visit
http://localhost:8000/. You should get a simple listing of all environments that tracd knows about. Follow the link to the environment you just created, and you should see Trac in action. If you only plan on managing a single project with trac you can have the standalone server skip the environment list by starting it like this:
$ tracd -s --port 8000 /path/to/myproject
Running Trac on a Web Server
Trac also supports AJP which may be your choice if you want to connect to IIS.
Generating the Trac cgi-bin directory
In 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 trac-admin.
There is, however, a bit of a chicken-and-egg problem. The 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:
mkdir -p /usr/share/trac/projects/my-project trac-admin /usr/share/trac/projects/my-project initenv trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy mv /tmp/deploy/* /usr/share/trac
Setting up the Plugin Cache
Some 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.
The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac. The basic procedure is described in the Adding Authentication section on the TracCgi page. To learn how to setup authentication for the frontend you're using, please refer to one of the following pages:
- TracStandalone if you use the standalone server,
- TracCgi if you use the CGI or FastCGI methods.
- TracModPython if you use the mod_python method.
Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.
Keep in mind that anonymous (not logged in) users can by default access most but not all of the features. You will need to configure authentication and grant additional permissions to authenticated users to see the full set of features.
