    66Trac uses a directory structure and a database for storing project data. The directory is referred to as the '''environment'''.

    8 Trac supports [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] databases. With PostgreSQL and MySQL you have to create the database before running `trac-admin initenv`.

     19A base configuration can be specified using the `--inherit` or `--config` options. The `--inherit` option can be specified one or more times to utilize a [TracIni#GlobalConfiguration global configuration]. The options specified in a `--config` file will be used to override the defaults when initializing `trac.ini`. See below for an [#SourceCodeRepository example] of defining repositories in a configuration file.

    1921=== Useful Tips
    2022
    2123 - Place your environment's directory on a filesystem which supports sub-second timestamps, as Trac monitors the timestamp of its configuration files and changes happening on a filesystem with too coarse-grained timestamp resolution may go undetected in Trac < 1.0.2. This is also true for the location of authentication files when using TracStandalone.
    2224
    23  - The user under which the web server runs will require file system write permission to the environment directory and all the files inside. Please remember to set the appropriate permissions. The same applies to the source code repository, although the user under which Trac runs will only require write access to a Subversion repository created with the BDB file system; for other repository types, check the corresponding plugin's documentation.
    24  
    25  - `initenv` does not create a version control repository for the specified path. If you wish to specify a default repository using the optional arguments to `initenv` you must create the repository first, otherwise you will see a message when initializing the environment: //Warning: couldn't index the default repository//.

    2727 - Non-ascii environment paths are not supported.
    2828
    29  - TracPlugins located in a [TracIni#inherit-plugins_dir-option shared plugins directory] that is defined in an [TracIni#GlobalConfiguration inherited configuration] are not enabled by default, in contrast to plugins in the environment `plugins` directory. Hence, if they need to create extra tables, for example, the tables will not be created during environment creation and you'll need to [TracUpgrade#UpgradetheTracEnvironment upgrade the environment]. Alternatively you can avoid the need to upgrade the environment by explicitly enabling the plugin in the inherited configuration, or in a configuration file using the `--config` option. See TracAdmin#FullCommandReference for more information.

    4040You will need to specify a database connection string at the time the environment is created. The default is SQLite, which is sufficient for most projects. The SQLite database file is stored in the environment directory, and can easily be [wiki:TracBackup backed up] together with the rest of the environment.

    42 Note that if the username or password of the connection string (if applicable) contains the `:`, `/` or `@` characters, they need to be [http://meyerweb.com/eric/tools/dencoder/ URL encoded].

     107=== Changing Database Backend

     109The TracAdmin `convert_db` command allows migrating between SQLite, MySQL and PostgreSQL databases.

     113== Deleting a Trac Environment
     114
     115The Trac environment can be deleted using standard filesystem utilities to delete the directory that was passed to the `initenv` command. For an environment using SQLite, this will also delete the SQLite database, which resides on-disk in the environment `db` directory. For an environment using PostgreSQL or MySQL, you will need to use the associated database utilities to delete the database.

    107117== Source Code Repository
    108118
    109 A single environment can be connected to more than one repository. However, by default Trac is not connected to any source code repository, and the ''Browse Source'' navigation item will not be displayed.

    111 There are several ways to connect repositories to an environment, see TracRepositoryAdmin. A single repository can be specified when the environment is created by passing the optional arguments `repository_type` and `repository_dir` to the `initenv` command.
     121Repositories can be defined at the time of environment creation by specifying a configuration file to the `initenv` command using the `--config` or `--inherit` options. Cached repositories will be synchronized if the repository connector(s) are enabled. Example:
