| 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 9431), 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]. |
