    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.
     4Trac is written in the Python programming language and needs a database, [https://sqlite.org/ SQLite], [https://www.postgresql.org/ PostgreSQL], or [https://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://jinja.pocoo.org Jinja2] templating system, though Genshi templates are supported until Trac 1.5.1.
    55
    66Trac can also be localized, and there is probably a translation available in your language. If you want 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.
    77
    8 If you're interested in contributing new translations for other languages or enhancing the existing translations, then please have a look at [trac:wiki:TracL10N TracL10N].

    1010What follows are generic instructions for installing and setting up Trac. While you may find instructions for installing Trac on specific systems at [trac:TracInstallPlatforms TracInstallPlatforms], please '''first read through these general instructions''' to get a good understanding of the tasks involved.
    … …  
    1616To install Trac, the following software packages must be installed:
    1717
    18  * [http://www.python.org/ Python], version >= 2.6 and < 3.0
    19    (note that we dropped the support for Python 2.5 in this release)
    20  * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
    21  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     18 * [https://www.python.org/ Python], version >= 3.5
     19 * [https://pypi.org/project/setuptools setuptools], version > 5.6
     20 * [https://pypi.org/project/Jinja2 Jinja2], version >= 2.9.3
    2221
    2322You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    … …  
    2524==== For the SQLite database #ForSQLite
    2625
    27 As you must be using Python 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
    28 
    29 Optionally, you may install a newer version of [http://pypi.python.org/pypi/pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.
     26You already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).

     28Optionally, you may install a newer version of [https://pypi.org/project/pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.
    3029
    3130==== For the PostgreSQL database #ForPostgreSQL
    3231
    3332You need to install the database and its Python bindings:
    34  * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    35  * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
     33 * [https://www.postgresql.org/ PostgreSQL], version 9.1 or later
     34 * [https://pypi.org/project/psycopg2 psycopg2], version 2.5 or later
    3635
    3736See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
    … …  
    3938==== For the MySQL database #ForMySQL
    4039
    41 Trac works well with MySQL, provided you follow the guidelines:
    42 
    43  * [http://mysql.com/ MySQL], version 5.0 or later
    44  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
     40Trac works well with MySQL, provided you use the following:
     41
     42 * [https://mysql.com/ MySQL], version 5.0 or later
     43 * [https://pypi.org/project/PyMySQL PyMySQL]
    4544
    4645Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.
    … …  
    5049==== Subversion
    5150
    52 [http://subversion.apache.org/ Subversion], 1.6.x or later and the '''''corresponding''''' Python bindings.
    53 
    54 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. [trac:TracSubversion] points you to [http://alagazam.net Alagazam], which works for me under Python 2.6.)
    55 
    56 For troubleshooting information, see the [trac:TracSubversion#Troubleshooting TracSubversion] page.
     51[https://subversion.apache.org/ Subversion], 1.14.x or later and the '''''corresponding''''' Python bindings.

    5855{{{#!div style="border: 1pt dotted; margin: 1em"
    5956**Note:**
    6057* Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], nor does it work yet with the newer `ctype`-style bindings.
    61 * If using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].

    8887==== Other Python Packages
    8988
    90  * [http://babel.edgewall.org Babel], version 0.9.6 or >= 1.3,
     89 * [http://babel.pocoo.org Babel], version >= 2.2,
    9190   needed for localization support

    93    for WikiRestructuredText.
    94  * [http://pygments.org Pygments] for
    95    [TracSyntaxColoring syntax highlighting].
    96  * [http://pytz.sf.net pytz] to get a complete list of time zones,
    97    otherwise Trac will fall back on a shorter list from
    98    an internal time zone implementation.
     91 * [http://pytz.sourceforge.net pytz] to get a complete list of time zones,
     92   otherwise Trac will fall back on a shorter list from
     93   an internal time zone implementation. Installing Babel
     94   will install pytz.
     95 * [http://docutils.sourceforge.net docutils],
     96   version >= 0.14, for WikiRestructuredText.

    110115It is assumed throughout this guide that you have elevated permissions as the `root` user or by prefixing commands with `sudo`. The umask `0002` should be used for a typical installation on a Unix-based platform.
    111116
    112 === Using `easy_install`
    113 Trac can be installed from PyPI or the Subversion repository using [http://pypi.python.org/pypi/setuptools setuptools].
    114 
    115 A few examples:
    116 
    117  - Install the latest stable version of Trac:
    118  {{{#!sh
    119 $ easy_install Trac
    120 }}}
    121  - Install latest development version:
    122  {{{#!sh
    123 $ easy_install http://download.edgewall.org/trac/Trac-latest-dev.tar.gz
    124 }}}
    125    Note that in this case you won't have the possibility to run a localized version of Trac;
    126    either use a released version or install from source
    127 
    128 More information can be found on the [trac:wiki:setuptools setuptools] page.
    129 
    130 {{{#!div style="border: 1pt dotted; margin: 1em"
    131 **Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation. More information may be found in [#DeployingTrac Deploying Trac].
    132 }}}
    133 
    134117=== Using `pip`
    135 'pip' is an easy_install replacement that is very useful to quickly install python packages.
    136 To get a Trac installation up and running in less than 5 minutes:
    137 
    138 Assuming you want to have your entire pip installation in `/opt/user/trac`
    139 
    140  -
    141  {{{#!sh
    142 pip install trac psycopg2
    143 }}}
    144 or
    145  -
    146  {{{#!sh
    147 pip install trac mysql-python
    148 }}}
    149 
    150 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (`libpq-dev`) or MySQL (`libmysqlclient-dev`) bindings.
    151 
    152 pip will automatically resolve all dependencies (like Genshi, pygments, etc.), download the latest packages from pypi.python.org and create a self contained installation in `/opt/user/trac`.
    153 
    154 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)
    155 
    156 Additionally, you can install several Trac plugins (listed [https://pypi.python.org/pypi?:action=browse&show=all&c=516 here]) through pip.
    157 
    158 === From source
    159 Using the python-typical setup at the top of the source directory also works. You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. `Trac-1.0.tar.gz`) from the [trac:TracDownload] page, or you can get the source directly from the repository. See [trac:TracRepositories#OfficialSubversionrepository TracRepositories] for details.
    160 
    161 {{{#!sh
    162 $ python ./setup.py install
    163 }}}
    164 
    165 ''You will need root permissions or equivalent for this step.''
    166 
    167 This will byte-compile the Python source code and install it as an .egg file or folder in the `site-packages` directory
    168 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as `htdocs` and `templates`.
    169 
    170 If you install from source and want to make Trac available in other languages, make sure Babel is installed. Only then, perform the `install` (or simply redo the `install` once again afterwards if you realize Babel was not yet installed):
    171 {{{#!sh
    172 $ python ./setup.py install
    173 }}}
    174 Alternatively, you can run `bdist_egg` and copy the .egg from `dist/` to the place of your choice, or you can create a Windows installer (`bdist_wininst`).
     118`pip` is the modern Python package manager and is included in Python distributions. `pip` will automatically
     119resolve the //required// dependencies (Jinja2 and
     120setuptools) and download the latest packages from pypi.org.
     121
     122You can also install directly from a source package. You can obtain the source in a tar or zip from the [trac:TracDownload] page. After extracting the archive, change to the directory containing `setup.py` and run:
     123
     124{{{#!sh
     125$ pip install .
     126}}}
     127
     128`pip` supports numerous other install mechanisms. It can be passed the URL of an archive or other download location. Here are some examples:
     129
     130* Install the latest stable version from a zip archive:
     131{{{#!sh
     132$ pip install https://download.edgewall.org/trac/Trac-latest.zip
     133}}}
     134* Install the latest development version from a tar archive:
     135{{{#!sh
     136$ pip install https://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     137}}}
     138* Install the unreleased 1.4-stable from subversion:
     139{{{#!sh
     140$ pip install svn+https://svn.edgewall.org/repos/trac/branches/1.2-stable
     141}}}
     142* Install the latest development preview (//not recommended for production installs//):
     143{{{#!sh
     144$ pip install --find-links=https://trac.edgewall.org/wiki/TracDownload Trac
     145}}}
     146
     147The optional dependencies can be installed from PyPI using `pip`:
     148{{{#!sh
     149$ pip install babel docutils pygments textile
     150}}}
     151
     152The optional dependencies can alternatively be
     153specified using the `extras` keys in the setup file:
     154{{{#!sh
     155$ pip install Trac[babel,rest,pygments,textile]
     156}}}
     157
     158`rest` is the extra that installs the `docutils`
     159dependency.
     160
     161Include `mysql` or `psycopg2-binary` in the
     162list if using the MySQL or PostgreSQL database.
     163
     164Additionally, you can install several Trac plugins from PyPI (listed [https://pypi.org/search/?c=Framework+%3A%3A+Trac here]) using pip. See TracPlugins for more information.
    175165
    176166=== Using installer
    … …  
    180170=== Using package manager
    181171
    182 Trac may be available in your platform's package repository. Note however, that the version provided by your package manager may not be the latest release.
    183 
    184 === Advanced `easy_install` Options
    185 
    186 To install Trac to a custom location, or find out about other advanced installation options, run:
    187 {{{#!sh
    188 easy_install --help
    189 }}}
    190 
    191 Also see [http://docs.python.org/2/install/index.html Installing Python Modules] for detailed information.
    192 
    193 Specifically, you might be interested in:
    194 {{{#!sh
    195 easy_install --prefix=/path/to/installdir
    196 }}}
    197 or, if installing Trac on a Mac OS X system:
    198 {{{#!sh
    199 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.6/site-packages
    200 }}}
    201 
    202 {{{#!div style="border: 1pt dotted; margin: 1em"
    203 **Mac OS X Note:** On Mac OS X 10.6,  running `easy_install trac` will install into `/usr/local` and `/Library/Python/2.6/site-packages` by default.
    204 
    205 The `tracd` and `trac-admin` commands will be placed in `/usr/local/bin` and will install the Trac libraries and dependencies into `/Library/Python/2.6/site-packages`, which is Apple's preferred location for third-party Python application installations.
    206 }}}
     172Trac may be available in your platform's package repository. However, your package manager may not provide the latest release of Trac.

    … …  
    215181}}}
    216182
    217 [TracAdmin trac-admin] will prompt you for the information it needs to create the environment: the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for any of these options, just press `<Enter>` to use the default value. 
     183[TracAdmin trac-admin] will prompt you for the information it needs to create the environment: the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for any of these options, just press `<Enter>` to use the default value.
    218184
    219185Using the default database connection string will always work as long as you have SQLite installed. For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    220186
    221187Also note that the values you specify here can be changed later using TracAdmin or directly editing the [TracIni conf/trac.ini] configuration file.
    222 
    223 {{{#!div style="border: 1pt dotted; margin: 1em"
    224 **Filesystem Warning:** 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, or HFS+ on OSX), 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. The best advice is to opt for a platform with sub-second timestamp resolution, regardless of the Trac version.
    225 }}}
    226188
    227189Finally, 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:

    240 {{{#!div style="border: 1pt dotted; margin: 1em"
    241 **Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation.
    242 
    243 If running `tracd`, the environment variable can be set system-wide or for just the user that runs the `tracd` process. There are several ways to accomplish this in addition to what is discussed here, and depending on the distribution of your OS.
    244 
    245 To be effective system-wide a shell script with the `export` statement may be added to `/etc/profile.d`. To be effective for a user session the `export` statement may be added to `~/.profile`.
    246 {{{#!sh
    247 export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
    248 }}}
    249 
    250 Alternatively, the variable can be set in the shell before executing `tracd`:
    251 {{{#!sh
    252 $ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
    253 }}}
    254 
    255 If running the Apache web server, !Ubuntu/Debian users should add the `export` statement to `/etc/apache2/envvars`. !RedHat/CentOS/Fedora should can add the `export` statement to `/etc/sysconfig/httpd`.

    264208
    265 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:

    273217 - [TracFastCgi FastCGI]
    274  - [wiki:TracModWSGI Apache with mod_wsgi] 
     218 - [wiki:TracModWSGI Apache with mod_wsgi]
    275219 - [TracModPython Apache with mod_python]
    276  - //[TracCgi CGI] (should not be used, as the performance is far from optimal)//
    277 
    278 Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS. Other deployment scenarios are possible: [trac:TracNginxRecipe nginx], [http://projects.unbit.it/uwsgi/wiki/Example#Traconapacheinasub-uri uwsgi], [trac:TracOnWindowsIisIsapi Isapi-wsgi] etc.

    280224==== Generating the Trac cgi-bin directory #cgi-bin
    281225
    282 In order for Trac to function properly with FastCGI you need to have a `trac.fcgi` file and for mod_wsgi a `trac.wsgi` file. These are Python scripts which load the appropriate Python code. They can be generated using the `deploy` option of [TracAdmin trac-admin].
    283 
    284 There is, however, a bit of a chicken-and-egg problem. The [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:
    285 {{{#!sh
    286 mkdir -p /usr/share/trac/projects/my-project
    287 trac-admin /usr/share/trac/projects/my-project initenv
    288 trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    289 mv /tmp/deploy/* /usr/share/trac
    290 }}}
    291 Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     226Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
     227[[TracAdminHelp(deploy)]]
     228
     229Grant the web server execution right on scripts in the `cgi-bin` directory.
     230
     231For example, the following yields a typical directory structure:
     232{{{#!sh
     233$ mkdir -p /var/trac
     234$ trac-admin /var/trac/<project> initenv
     235$ trac-admin /var/trac/<project> deploy /var/www
     236$ ls /var/www
     237cgi-bin htdocs
     238$ chmod ugo+x /var/www/cgi-bin/*
     239}}}

    293241==== Mapping Static Resources
    … …  
    295243Without additional configuration, Trac will handle requests for static resources such as stylesheets and images. For anything other than a TracStandalone deployment, this is not optimal as the web server can be set up to directly serve the static resources. For CGI setup, this is '''highly undesirable''' as it causes abysmal performance.
    296244
    297 Web servers such as [http://httpd.apache.org/ Apache] allow you to create //Aliases// to resources, giving them a virtual URL that doesn't necessarily reflect their location on the file system. We can map requests for static resources directly to directories on the file system, to avoid Trac processing the requests.

We can map requests for static resources directly to directories on the file system, to avoid Trac processing the requests.
    298246
    299247There are two primary URL paths for static resources: `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible at the `/chrome/<plugin>` path.
    300248
    301 A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
    302 
    303 The resources are extracted using the [TracAdmin trac-admin]` <environment> deploy` command:
    304 [[TracAdminHelp(deploy)]]
    305 
    306 The target `<directory>` will contain an `htdocs` directory with:
     249A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command (discussed in the previous section) must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     250
     251The `deploy` command creates an `htdocs` directory with:
    307252 - `common/` - the static resources of Trac
    308253 - `site/` - a copy of the environment's `htdocs/` directory
    … …  
    322267Assuming the deployment has been done this way:
    323268{{{#!sh
    324 $ trac-admin /var/trac/env deploy /path/to/shared/trac
     269$ trac-admin /var/trac/<project> deploy /var/www
    325270}}}
    326271
    … …  
    366311}}}
    367312
    368 Another alternative to aliasing `/trac/chrome/common` is having Trac generate direct links for those static resources (and only those), using the [[TracIni#trac-section| [trac] htdocs_location]] configuration setting:

    387332Trac uses HTTP authentication. You'll need to configure your webserver to request authentication when the `.../login` URL is hit (the virtual path of the "login" button). Trac will automatically pick the `REMOTE_USER` variable up after you provide your credentials. Therefore, all user management goes through your web server configuration. Please consult the documentation of your web server for more info.
    388333
    389 The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
