 v1 }}} [wiki:TracAdmin trac-admin] will ask you for the name of the project, the database connection string (explained below), and the type and path to your source code repository. [wiki:TracAdmin trac-admin] will ask you for the name of the project and the database connection string (explained below). ''Note: The web server user will require file system write permission to ''Note: 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 Subversion repository Trac is eventually using, although Trac will only require read access as long as you're not using the BDB file system. Also, it seems that project names with spaces can be problematic for authentication (see [trac:#7163]).'' 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. Also, it seems that project names with spaces can be problematic for authentication (see [trac:#7163]).'' ''Note: "initenv" when using svn repository does not imply that trac-admin will perform "svnadmin create" for the specified repository path. You need to perform the "svnadmin create" prior to trac-admin initenv if you're creating a new svn repository altogether with a new trac environment, otherwise you will see a message "Warning: couldn't index the repository" when initializing the environment.'' == Database Connection Strings == [wiki:TracBackup backed up] together with the rest of the environment. === Embedded SQLite Connection String === The connection string for an embedded SQLite database is: === SQLite Connection String === The connection string for an SQLite database is: {{{ sqlite:db/trac.db }}} where db/trac.db is the path to the database file within the Trac environment. === PostgreSQL Connection String === == Source Code Repository == You'll first have to provide the ''type'' of your repository (e.g. svn for Subversion, which is the default), then the ''path'' where the repository is located. Since version 0.12, a single Trac environment can be connected to more than one repository. There are many different ways to connect repositories to an environment, see TracRepositoryAdmin. This page also details the various attributes that can be set for a repository (like type, url, description). If you don't want to use Trac with a source code repository, simply leave the ''path'' empty (the ''type'' information doesn't matter, then). In Trac 0.12 trac-admin no longer asks questions related to repositories. Therefore, by default Trac is not connected to any source code repository, and the ''Browse Source'' toolbar item will not be displayed. You can also explicitly disable the trac.versioncontrol.* components (which are otherwise still loaded) {{{ [components] trac.versioncontrol.* = disabled }}} For some systems, it is possible to specify not only the path to the repository, For some version control systems, it is possible to specify not only the path to the repository, but also a ''scope'' within the repository. Trac will then only show information related to the files and changesets below that scope. The Subversion backend for Trac supports this; for other types, check the corresponding plugin's documentation. Example of a configuration for a Subversion repository: Example of a configuration for a Subversion repository used as the default repository: {{{ [trac] * db * trac.db - The SQLite database (if you're using SQLite). * htdocs - directory containing web resources, which can be referenced in Genshi templates. '''''(0.11 only)''''' * htdocs - directory containing web resources, which can be referenced in Genshi templates.

'''Caveat:''' ''don't confuse a Trac environment directory with the source code repository directory.'' This is a common beginners' mistake. It happens that the structure for a Trac environment is loosely modelled after the Subversion repository directory structure, but those are two disjoint entities and they are not and ''must not'' be located at the same place. ---- See also: TracAdmin, TracBackup, TracIni, TracGuide
