     1= Trac Installation Guide for 0.11 =
     2[[TracGuideToc]]
     3
     4Trac 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.
     5
     6What 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 ==
     9For 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{{{
     11sudo easy_install Trac==0.11
     12}}}
     13
     14== Requirements - also older versions possible ==
     15
     16To install Trac, the following software packages must be installed:
     17
     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"]
     22 * [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
     39 * [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 ===
     52
     53==== Version Control System ====
     54
     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.
     62
     63==== Web Server ====
     64 * A CGI-capable web server (see TracCgi), or
     65 * 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
     71For 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
     81Please 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!).
     82
     83== Installing Trac ==
     84
     85One way to install Trac is using `setuptools`.
     86With setuptools you can install Trac from the subversion repository; for example,
     87to install release version 0.11b2 do:
     88{{{
     89easy_install http://svn.edgewall.org/repos/trac/tags/trac-0.11b2
     90}}}
     91
     92But of course the python-typical setup at the top of the source directory also works:
     93{{{
     94$ python ./setup.py install
     95}}}
     96
     97''Note: you'll need root permissions or equivalent for this step.''
     98
     99This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
     100of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
     101
     102The 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.
     103
     104=== Advanced Options ===
     105
     106To install Trac to a custom location, or find out about other advanced installation options, run:
     107{{{
     108easy_install --help
     109}}}
     110
     111Also see [http://docs.python.org/inst/inst.html Installing Python Modules] for detailed information.
     112
     113Specifically, you might be interested in:
     114{{{
     115easy_install --prefix=/path/to/installdir
     116}}}
     117or, if installing Trac to a Mac OS X system:
     118{{{
     119easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
     120}}}
     121
     122The 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.
     123
     124== Creating a Project Environment ==
     125
     126A [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.
     127
     128A new environment is created using [wiki:TracAdmin trac-admin]:
     129{{{
     130$ trac-admin /path/to/myproject initenv
     131}}}
     132
     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
     135Also 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
     141
     142== Running the Standalone Server ==
     143
     144After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
     145{{{
     146$ tracd --port 8000 /path/to/myproject
     147}}}
     148
     149Then, 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:
     150{{{
     151$ tracd -s --port 8000 /path/to/myproject
     152}}}
     153
     154
     155== Running Trac on a Web Server ==
     156
     157Trac 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.
     158
     159If 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.
     160
     161== Configuring Authentication ==
     162
     163The 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 [wiki:TracCgi#AddingAuthentication "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:
     164
     165 * TracStandalone if you use the standalone server, `tracd`.
     166 * TracCgi if you use the CGI or FastCGI methods.
     167 * TracModPython if you use the mod_python method.
     168
     169== Trac 0.11 & SVN on Mac OS X Leopard (10.5) ==
     170
     171 * TracOnLeopardServer
     172
     173== Using Trac ==
     174
     175Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.
     176
     177Keep 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 [wiki:TracPermissions permissions] to authenticated users to see the full set of features.
     178
