    1 = Trac Storage - The Environment =
    2 Trac uses a directory structure and an embedded [http://www.sqlite.org/ SQLite] database as storage.
     1= The Trac Environment =
     2
     3Trac uses a directory structure and a database for storing project data. The directory is referred to as the “environment”.
    34
    45== Creating an Environment ==
    5 A new Trac environment is created using [wiki:TracAdmin trac-admin], like:
    66
     7A new Trac environment is created using [wiki:TracAdmin trac-admin]:
    78{{{
    89$ trac-admin /path/to/projectenv initenv
    910}}}
    1011
    11 [wiki:TracAdmin trac-admin] will ask you where your subversion repository is located and
    12 where it can find the trac templates directory (the default value should work for a typical install).
     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.

    14 '''Note:''' The web server user will require file system write permission to the environment
    15 directory and all the files inside. '''Remember to set the appropriate permissions.''
     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.''
    1621
    17 The same applies for the subversion repository files (unless using the [http://svn.collab.net/repos/svn/trunk/notes/fsfs FSFS Subversion backend], something we highly recommend.
     22== Database Connection Strings ==
    1823
     24Since version 0.9, Trac supports both [http://sqlite.org/ SQLite],
     25[http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ 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.
    1930
     31The connection string for an embedded SQLite database is:
     32{{{
     33sqlite:db/trac.db
     34}}}
     35
     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:
     40{{{
     41postgres://johndoe:letmein@localhost/trac
     42}}}
     43
     44If PostgreSQL is running on a non-standard port (for example 9342), use:
     45{{{
     46postgres://johndoe:letmein@localhost:9342/trac
     47}}}
     48
     49Note that with PostgreSQL you will have to create the database before running
     50`trac-admin initenv`.
     51
     52And make sure PostgreSQl DB name is "trac". What worked for me:
     53And didn't work uppercase trac-user-name
     54{{{
     55sudo su - postgres -c createdb trac
     56sudo su - postgres -c psql trac
     57CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name';
     58}}}
     59
     60(Just to remind you, if you don't have a sudo/su setup, you just need to do the createdb and psql statements. That threw me the first couple of times I read this.)
     61
     62== Source Code Repository ==
     63
     64You'll first have to provide the ''type'' of your repository (e.g. `svn` for Subversion,
     65which is the default), then the ''path'' where the repository is located.
     66
     67If you don't want to use Trac with a source code repository, simply leave the ''path'' empty
     68(the ''type'' information doesn't matter, then).
     69
     70For some systems, it is possible to specify not only the path to the repository,
     71but also a ''scope'' within the repository. Trac will then only show information
     72related to the files and changesets below that scope. The Subversion backend for
     73Trac supports this; for other types, check the corresponding plugin's documentation.
     74
     75Example of a configuration for a Subversion repository:
     76{{{
     77[trac]
     78repository_type = svn
     79repository_dir = /path/to/your/repository
     80}}}
     81
     82The configuration for a scoped Subversion repository would be:
     83{{{
     84[trac]
     85repository_type = svn
     86repository_dir = /path/to/your/repository/scope/within/repos
     87}}}

     108It happens that the above structure is loosely modelled after the Subversion repository directory
