| 5 | | Trac is written in the Python programming language and needs a database, [http://sqlite.org/ SQLite], [http://postgresql.org/ PostgreSQL], [http://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://genshi.edgewall.org Genshi] templating system. |
| 6 | | |
| 7 | | 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. |
| 8 | | |
| 9 | | See TracUpgrade for instructions on how to upgrade an existing installation. |
| 10 | | |
| 11 | | |
| 12 | | == Quick Install a Released Version == |
| 13 | | For a quick install, first make sure you have [http://python.org/download Python] (2.3-2.6) and [http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install easy_install]. |
| 14 | | |
| 15 | | Then enter (''omitting 'sudo' if not applicable'') |
| 16 | | {{{ |
| 17 | | sudo easy_install Trac |
| 18 | | }}} |
| 19 | | to install Trac, SQLite, and Genshi. |
| 20 | | |
| 21 | | |
| 22 | | == Requirements == |
| 23 | | The hardware requirements for running Trac obviously depend on the expected data volume (number of wiki pages, tickets, revisions) and traffic. Very small projects will run fine with a 500MHz processor and 128MB RAM using SQLite. In general, the more RAM, the better. A fast hard disk also helps. |
| 24 | | |
| | 4 | Trac 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 | |
| | 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 **first** have installed the optional package [#OtherPythonPackages Babel]. Lacking Babel, you will only get the default english version, as usual. If you install Babel later on, you will need to re-install Trac. |
| | 7 | |
| | 8 | If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [trac:wiki:TracL10N TracL10N]. |

| | 12 | [[PageOutline(2-3,Installation Steps,inline)]] |
| | 13 | |
| | 14 | == Dependencies == |
| | 15 | === Mandatory Dependencies |
| 27 | | * [http://www.python.org/ Python], version >=2.3 (<3.0) |
| 28 | | * 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). |
| 29 | | * For RPM-based systems you might also need the `python-devel` and `python-xml` packages. |
| 30 | | * See instructions in [trac:wiki:TracOnWindows/Python2.5 TracOnWindows/Python2.5] |
| 31 | | * [wiki:setuptools], version >= 0.6 |
| 32 | | * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.5 (was version >= 0.4.1 on previous 0.11 release candidates) |
| 33 | | * You also need a database system and the corresponding python drivers for it. |
| 34 | | The database can be either SQLite, PostgreSQL or MySQL. |
| 35 | | * Optional if some plugins require it: [http://www.clearsilver.net/ ClearSilver] |
| 36 | | |
| 37 | | ==== For SQLite ==== |
| | 18 | * [http://www.python.org/ Python], version >= 2.4 and < 3.0 |
| | 19 | (note that we dropped the support for Python 2.3 in this release) |
| | 20 | * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6 |
| | 21 | * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6 |
| | 22 | |
| | 23 | You also need a database system and the corresponding python bindings. |
| | 24 | The database can be either SQLite, PostgreSQL or MySQL. |
| | 25 | |
| | 26 | ==== For the SQLite database #ForSQLite |
| 50 | | That way, the latest SQLite version will be downloaded and built into the |
| 51 | | bindings. |
| 52 | | |
| 53 | | If you're still using SQLite 2.x, you'll need pysqlite 1.0.x, although this |
| 54 | | package is not easy to find anymore. For SQLite 3.x, try not to use |
| 55 | | pysqlite 1.1.x, which has been deprecated in favor of pysqlite 2.x. |
| 56 | | |
| 57 | | See additional information in [trac:PySqlite PySqlite]. |
| 58 | | |
| 59 | | ==== For PostgreSQL ==== |
| 60 | | |
| | 38 | This will extract the SQLite code and build the bindings. |
| | 39 | |
| | 40 | To install SQLite, your system may require the development headers. Without these you will get various GCC related errors when attempting to build: |
| | 41 | |
| | 42 | {{{ |
| | 43 | $ apt-get install libsqlite3-dev |
| | 44 | }}} |
| | 45 | |
| | 46 | SQLite 2.x is no longer supported, and neither is !PySqlite 1.1.x. |
| | 47 | |
| | 48 | A known bug !PySqlite versions 2.5.2-4 prohibits upgrade of trac databases |
| | 49 | from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and |
| | 50 | older. See [trac:#9434] for more detail. |
| | 51 | |
| | 52 | See additional information in [trac:PySqlite]. |
| | 53 | |
| | 54 | ==== For the PostgreSQL database #ForPostgreSQL |
| | 55 | |
| | 56 | You need to install the database and its Python bindings: |
| 62 | | * [http://initd.org/projects/psycopg2 psycopg2] |
| 63 | | * See [trac:wiki:DatabaseBackend#Postgresql DatabaseBackend] |
| 64 | | |
| 65 | | '''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. |
| 66 | | |
| 67 | | ==== For MySQL ==== |
| 68 | | |
| 69 | | * [http://mysql.com/ MySQL], version 4.1 or later ([http://askmonty.org/wiki/index.php/MariaDB MariaDB] might work as well) |
| 70 | | * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later |
| 71 | | |
| 72 | | See [trac:MySqlDb MySqlDb] for more detailed information. |
| 73 | | It is ''very'' important to read carefully that page before creating the database. |
| 74 | | |
| 75 | | == Optional Requirements == |
| | 58 | * [http://pypi.python.org/pypi/psycopg2 psycopg2] |
| | 59 | |
| | 60 | See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details. |
| | 61 | |
| | 62 | |
| | 63 | ==== For the MySQL database #ForMySQL |
| | 64 | |
| | 65 | Trac can now work quite well with MySQL, provided you follow the guidelines. |
| | 66 | |
| | 67 | * [http://mysql.com/ MySQL], version 5.0 or later |
| | 68 | * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later |
| | 69 | |
| | 70 | It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database. |
| | 71 | |
| | 72 | === Optional Dependencies |
| 79 | | '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently not supported (although Windows UNC paths such as {{{\\machine_name\path\to\svn}}} do work). |
| 80 | | |
| 81 | | * [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 [trac:TracSubversion TracSubversion] |
| 82 | | * 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). |
| 83 | | * 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`. |
| 84 | | * There are [http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 pre-compiled bindings] available for win32. |
| 85 | | * Support for other version control systems is provided via third-parties. See [trac:PluginList PluginList] and [trac:VersioningSystemBackend VersioningSystemBackend]. |
| | 76 | ===== Subversion ===== |
| | 77 | * [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. |
| | 78 | |
| | 79 | 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.) |
| | 80 | |
| | 81 | Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings. [Is there a ticket for implementing ctype bindings?] |
| | 82 | |
| | 83 | |
| | 84 | '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported]. |
| | 85 | |
| | 86 | |
| | 87 | ===== Others ===== |
| | 88 | |
| | 89 | Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersioningSystemBackend]. |
| 88 | | * A CGI-capable web server (see TracCgi), or |
| 89 | | * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or |
| 90 | | * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp]), or |
| 91 | | * [http://httpd.apache.org/ Apache] with [http://code.google.com/p/modwsgi/ mod_wsgi] (see [wiki:TracModWSGI] or http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac) or |
| 92 | | * 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. |
| 93 | | * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython) |
| 94 | | * When installing mod_python the development versions of Python and Apache are required (actually the libraries and header files) |
| 95 | | |
| 96 | | 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 [trac:wiki:TracModPython2.7 TracModPython2.7]). This guide hasn't been updated since 0.84, so it may or may not work. |
| 97 | | |
| 98 | | ==== Other Python Utilities ==== |
| 99 | | * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 for WikiRestructuredText. |
| 100 | | * [http://pygments.pocoo.org Pygments] for '''syntax highlighting''', although [http://silvercity.sourceforge.net/ SilverCity] >= 0.9.7 and/or [http://gnu.org/software/enscript/enscript.html GNU Enscript] are also possible. Refer to TracSyntaxColoring for details. |
| 101 | | * [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. |
| 102 | | |
| 103 | | '''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]. |
| | 92 | A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below. |
| | 93 | |
| | 94 | Alternatively you configure Trac to run in any of the following environments. |
| | 95 | * [http://httpd.apache.org/ Apache] with |
| | 96 | - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and |
| | 97 | http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac |
| | 98 | - [http://modpython.org/ mod_python 3.3.1], deprecated: see TracModPython) |
| | 99 | * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi) |
| | 100 | * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web |
| | 101 | server (see [trac:TracOnWindowsIisAjp]) |
| | 102 | * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script |
| | 103 | is highly discouraged''', better use one of the previous options. |
| | 104 | |
| | 105 | |
| | 106 | ==== Other Python Packages ==== |
| | 107 | |
| | 108 | * [http://babel.edgewall.org Babel], version >= 0.9.5, |
| | 109 | needed for localization support[[BR]] |
| | 110 | ''Note: '' If you want to be able to use the Trac interface in other languages, then make sure you first have installed the optional package Babel. Lacking Babel, you will only get the default english version, as usual. If you install Babel later on, you will need to re-install Trac. |
| | 111 | * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 |
| | 112 | for WikiRestructuredText. |
| | 113 | * [http://pygments.pocoo.org Pygments] for |
| | 114 | [wiki:TracSyntaxColoring syntax highlighting]. |
| | 115 | [http://silvercity.sourceforge.net/ SilverCity] and/or |
| | 116 | [http://gnu.org/software/enscript/enscript.html Enscript] may still be used |
| | 117 | but are deprecated and you really should be using Pygments. |
| | 118 | * [http://pytz.sf.net pytz] to get a complete list of time zones, |
| | 119 | otherwise Trac will fall back on a shorter list from |
| | 120 | an internal time zone implementation. |
| | 121 | |
| | 122 | '''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] or [trac:IrcChannel]. |
| 108 | | |
| 109 | | One way to install Trac is using `setuptools`. |
| 110 | | With setuptools you can install Trac from the subversion repository; for example, |
| 111 | | to install release version 0.11 do: |
| 112 | | {{{ |
| 113 | | easy_install http://svn.edgewall.org/repos/trac/tags/trac-0.11 |
| 114 | | }}} |
| 115 | | |
| 116 | | But of course the python-typical setup at the top of the source directory also works: |
| | 128 | === Using `easy_install` |
| | 129 | One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools]. |
| | 130 | With setuptools you can install Trac from the subversion repository; |
| | 131 | |
| | 132 | A few examples: |
| | 133 | |
| | 134 | - install Trac 0.12: |
| | 135 | {{{ |
| | 136 | easy_install Trac==0.12 |
| | 137 | }}} |
| | 138 | |
| | 139 | - install latest development version 0.12dev: |
| | 140 | {{{ |
| | 141 | easy_install Trac==dev |
| | 142 | }}} |
| | 143 | Note that in this case you won't have the possibility to run a localized version of Trac; |
| | 144 | either use a released version or install from source |
| | 145 | |
| | 146 | === Using `pip` |
| | 147 | 'pip' is an easy_install replacement that is very useful to quickly install python packages. |
| | 148 | To get a trac installation up and running in less than 5 minutes: |
| | 149 | |
| | 150 | Assuming you want to have your entire pip installation in /opt/user/trac |
| | 151 | |
| | 152 | - |
| | 153 | {{{ |
| | 154 | pip -E /opt/user/trac install trac psycopg2 |
| | 155 | }}} |
| | 156 | or |
| | 157 | - |
| | 158 | {{{ |
| | 159 | pip -E /opt/user/trac install trac mysql-python |
| | 160 | }}} |
| | 161 | |
| | 162 | Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings. |
| | 163 | |
| | 164 | pip will automatically resolve all dependencies (like Genshi, pygments, etc.) and download the latest packages on pypi.python.org and create a self contained installation in /opt/user/trac |
| | 165 | |
| | 166 | All 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) |
| | 167 | |
| | 168 | Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip. |
| | 169 | |
| | 170 | |
| | 171 | |
| | 172 | === From source |
| | 173 | Of course, using the python-typical setup at the top of the source directory also works. |
| | 174 | |
| | 175 | You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. Trac-0.12.tar.gz), or you can get the source directly from the repository (see [trac:SubversionRepository] for details). |
| | 176 | |
| 157 | | [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. |
| 158 | | |
| 159 | | Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file. |
| 160 | | |
| 161 | | ''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:'' |
| 162 | | |
| 163 | | chown -R apache.apache /path/to/myproject |
| | 225 | [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. |
| | 226 | |
| | 227 | Using the default database connection string in particular will always work as long as you have SQLite installed. |
| | 228 | For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point. |
| | 229 | |
| | 230 | Since 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. |
| | 231 | |
| | 232 | Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file. |
| | 233 | |
| | 234 | Finally, 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: |
| | 235 | {{{ |
| | 236 | # chown -R apache.apache /path/to/myproject |
| | 237 | }}} |
| 211 | | You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever files are committed to the repository. The description of the commit needs to contain one of the following formulas: |
| 212 | | * '''Refs #123''' - to reference this changeset in #123 ticket |
| 213 | | * '''Fixes #123''' - to reference this changeset and close #123 ticket with the default status ''fixed'' |
| 214 | | |
| 215 | | All you have to do is to edit the ''post-commit'' hook in your SVN repository and make it execute ''trac-post-commit-hook'' coming with Trac. |
| 216 | | |
| 217 | | If you are editing the ''post-commit'' hook for the first time you need to navigate to your SVN repository's hooks subfolder and rename existing there ''post-commit'' template: |
| 218 | | |
| 219 | | {{{ |
| 220 | | $ cd /path/to/svn/repository/hooks |
| 221 | | $ mv post-commit.tmpl post-commit |
| 222 | | $ chmod 755 post-commit |
| 223 | | }}} |
| 224 | | |
| 225 | | Next open it in any text editor and add a line with path to the Trac environment connected with this SVN repository and another line executing the ''trac-post-commit-hook'' script: |
| 226 | | |
| 227 | | {{{ |
| 228 | | REPOS="$1" |
| 229 | | REV="$2" |
| 230 | | TRAC_ENV="/path/to/your/trac/project" |
| 231 | | |
| 232 | | /usr/bin/python /usr/local/bin/trac-post-commit-hook -p "$TRAC_ENV" -r "$REV" |
| 233 | | }}} |
| 234 | | |
| 235 | | Make sure that ''trac-post-commit-hook'' exists in above path with execution permissions for the same user which SVN is running from. This script can be found in contrib subfolder of your Trac distribution and the latest version can be always downloaded from [source:trunk/contrib/trac-post-commit-hook]. |
| 236 | | |
| 237 | | |
| 238 | | == Platform-specifics installations == |
| 239 | | |
| 240 | | * See [trac:TracInstallPlatforms TracInstallPlatforms] |
| 241 | | |
| | 285 | You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever changes are committed to the repository. The description of the commit needs to contain one of the following formulas: |
| | 286 | * '''`Refs #123`''' - to reference this changeset in `#123` ticket |
| | 287 | * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed'' |
| | 288 | |
| | 289 | This functionality requires a post-commit hook to be installed as described in [wiki:TracRepositoryAdmin#ExplicitSync TracRepositoryAdmin], and enabling the optional commit updater components by adding the following line to the `[components]` section of your [wiki:TracIni#components-section trac.ini], or enabling the components in the "Plugins" admin panel. |
| | 290 | {{{ |
| | 291 | tracopt.ticket.commit_updater.* = enabled |
| | 292 | }}} |
| | 293 | For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel. |
