    v2 v3  
    1 = Trac Storage - The Environment = 
    2  
    3 Trac uses a directory structure and a database for storing project data. 
    4  
    5 == Creating an Environment == 
    6  
    7 A new Trac environment is created using [wiki:TracAdmin trac-admin]: 
    8 {{{ 
    9 $ trac-admin /path/to/projectenv initenv 
    10 }}} 
    11  
    12 [wiki:TracAdmin trac-admin] will ask you for the name of the project, the 
    13 database connection string (explained below), and where your subversion 
    14 repository is located. 
    15  
    16   ''Note: The web server user will require file system write permission to 
    17 the environment directory and all the files inside. Please remember to set 
    18 the appropriate permissions. The same applies to the Subversion 
    19 repository, although Trac will only require read access as long as you're 
    20 not using the BDB file system.'' 
    21  
    22 == Database Connection Strings == 
    23  
    24 Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] and 
    25 [http://www.postgresql.org/ PostgreSQL] as database backends.  The default 
    26 is to use SQLite, which is probably sufficient for most projects. The database file 
    27 is then stored in the environment directory, and can easily be 
    28 [wiki:TracBackup backed up] together with the rest of the environment. 
    29  
    30 The connection string for an embedded SQLite database is: 
    31 {{{ 
    32 sqlite:db/trac.db 
    33 }}} 
    34  
    35 If you want to use PostgreSQL instead, you'll have to use a different 
    36 connection string. For example, to connect to a database on the same 
    37 machine called `trac`, that allows access to the user `johndoe` with 
    38 the password `letmein`, use: 
    39 {{{ 
    40 postgres://johndoe:letmein@localhost/trac 
    41 }}} 
    42  
    43 If PostgreSQL is running on a non-standard port (for example 9342), use: 
    44 {{{ 
    45 postgres://johndoe:letmein@localhost:9342/trac 
    46 }}} 
    47  
    48 Note that with PostgreSQL you will have to create the database before running 
    49 `trac-admin initenv`. 
    50  
    51 == Directory Structure == 
    52  
    53 An environment directory will usually consist of the following files and directories: 
    54  
    55  * `README` - Brief description of the environment. 
    56  * `VERSION` - Contains the environment version identifier. 
    57  * `attachments` - Attachments to wiki pages and tickets are stored here. 
    58  * `conf` 
    59    * `trac.ini` - Main configuration file. See TracIni. 
    60  * `db` 
    61    * `trac.db` - The SQLite database (if you're using SQLite). 
    62  * `plugins` - Environment-specific [wiki:TracPlugins plugins] (Python eggs) 
    63  * `templates` - Custom environment-specific templates. 
    64    * `site_css.cs` - Custom CSS rules. 
    65    * `site_footer.cs` - Custom page footer. 
    66    * `site_header.cs` - Custom page header. 
    67  * `wiki-macros` - Environment-specific [wiki:WikiMacros Wiki macros].
