    v1 v1  
     1= The Trac Environment =
     3Trac uses a directory structure and a database for storing project data. The directory is referred to as the “environment”.
     5== Creating an Environment ==
     7A new Trac environment is created using [wiki:TracAdmin trac-admin]:
     9$ trac-admin /path/to/projectenv initenv
     12[wiki:TracAdmin trac-admin] will ask you for the name of the project, the
     13database connection string (explained below), and the type and path to
     14your source code repository.
     16''Note: The web server user will require file system write permission to
     17the environment directory and all the files inside. Please remember to set
     18the appropriate permissions. The same applies to the Subversion repository
     19Trac is eventually using, although Trac will only require read access as long
     20as you're not using the BDB file system.''
     22== Database Connection Strings ==
     24Since version 0.9, Trac supports both [ SQLite],
     25[ PostgreSQL] and [ MySQL] as
     26database backends.  The default is to use SQLite, which is probably sufficient
     27for most projects. The database file is then stored in the environment
     28directory, and can easily be [wiki:TracBackup backed up] together with the
     29rest of the environment.
     31The connection string for an embedded SQLite database is:
     36If you want to use PostgreSQL or MySQL instead, you'll have to use a
     37different connection string. For example, to connect to a PostgreSQL
     38database on the same machine called `trac`, that allows access to the
     39user `johndoe` with the password `letmein`, use:
     44If PostgreSQL is running on a non-standard port (for example 9342), use:
     49Note that with PostgreSQL you will have to create the database before running
     50`trac-admin initenv`.
     52And make sure PostgreSQl DB name is "trac". What worked for me:
     53And didn't work uppercase trac-user-name
     55sudo su - postgres -c createdb trac
     56sudo su - postgres -c psql trac
     57CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name';
     60== Source Code Repository ==
     62You'll first have to provide the ''type'' of your repository (e.g. `svn` for Subversion,
     63which is the default), then the ''path'' where the repository is located.
     65If you don't want to use Trac with a source code repository, simply leave the ''path'' empty
     66(the ''type'' information doesn't matter, then).
     68For some systems, it is possible to specify not only the path to the repository,
     69but also a ''scope'' within the repository. Trac will then only show information
     70related to the files and changesets below that scope. The Subversion backend for
     71Trac supports this; for other types, check the corresponding plugin's documentation.
     73Example of a configuration for a Subversion repository:
     76repository_type = svn
     77repository_dir = /path/to/your/repository
     80The configuration for a scoped Subversion repository would be:
     83repository_type = svn
     84repository_dir = /path/to/your/repository/scope/within/repos
     87== Directory Structure ==
     89An environment directory will usually consist of the following files and directories:
     91 * `README` - Brief description of the environment.
     92 * `VERSION` - Contains the environment version identifier.
     93 * `attachments` - Attachments to wiki pages and tickets are stored here.
     94 * `conf`
     95   * `trac.ini` - Main configuration file. See TracIni.
     96 * `db`
     97   * `trac.db` - The SQLite database (if you're using SQLite).
     98 * `plugins` - Environment-specific [wiki:TracPlugins plugins] (Python eggs)
     99 * `templates` - Custom environment-specific templates.
     100   * `site_css.cs` - Custom CSS rules.
     101   * `site_footer.cs` - Custom page footer.
     102   * `site_header.cs` - Custom page header.
     103 * `wiki-macros` - Environment-specific [wiki:WikiMacros Wiki macros].
     105  '''Note: don't confuse a Trac environment directory with the source code repository directory.
     106It happens that the above structure is loosely modelled after the Subversion repository directory
     107structure, but they are not and ''must not'' be located at the same place.'''
