The same applies to the Subversion repository 19 19 Trac is eventually using, although Trac will only require read access as long 20 as you're not using the BDB file system.'' 20 as you're not using the BDB file system. Also, it seems that project names 21 with spaces can be problematic for authentication (see [trac:#7163]).'' 21 22 22 23 == Database Connection Strings == 23 24 24 Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] ,25 [http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] as26 database backends. The default is to use SQLite, which is probably sufficient 27 for most projects. The database file is then stored in the environment 28 directory, and can easily be [wiki:TracBackup backed up] together with the 29 rest of the environment.25 Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] and 26 [http://www.postgresql.org/ PostgreSQL] database backends. Preliminary 27 support for [http://mysql.com/ MySQL] was added in 0.10. The default is 28 to use SQLite, which is probably sufficient for most projects. The database 29 file is then stored in the environment directory, and can easily be 30 [wiki:TracBackup backed up] together with the rest of the environment. 30 31 32 === Embedded SQLite Connection String === 31 33 The connection string for an embedded SQLite database is: 32 34 {{{ … … 34 36 }}} 35 37 38 === PostgreSQL Connection String === 36 39 If you want to use PostgreSQL or MySQL instead, you'll have to use a 37 40 different connection string. For example, to connect to a PostgreSQL … … 41 44 postgres://johndoe:letmein@localhost/trac 42 45 }}} 46 ''Note that due to the way the above string is parsed, the "/" and "@" characters cannot be part of the password.'' 43 47 44 48 If PostgreSQL is running on a non-standard port (for example 9342), use: … … 47 51 }}} 48 52 53 On UNIX, you might want to select a UNIX socket for the transport, 54 either the default socket as defined by the PGHOST environment variable: 55 {{{ 56 postgres://user:password@/database 57 }}} 58 or a specific one: 59 {{{ 60 postgres://user:password@/database?host=/path/to/socket/dir 61 }}} 62 49 63 Note that with PostgreSQL you will have to create the database before running 50 64 `trac-admin initenv`. 51 65 52 And make sure PostgreSQl DB name is "trac". What worked for me: 53 And didn't work uppercase trac-user-name 66 See the [http://www.postgresql.org/docs/ PostgreSQL documentation] for detailed instructions on how to administer [http://postgresql.org PostgreSQL]. 67 Generally, the following is sufficient to create a database user named `tracuser`, and a database named `trac`. 54 68 {{{ 55 sudo su - postgres -c createdb trac 56 sudo su - postgres -c psql trac 57 CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name'; 69 createuser -U postgres -E -P tracuser 70 createdb -U postgres -O tracuser -E UTF8 trac 71 }}} 72 When running `createuser` you will be prompted for the password for the user 'tracuser'. This new user will not be a superuser, will not be allowed to create other databases and will not be allowed to create other roles. These privileges are not needed to run a trac instance. If no password is desired for the user, simply remove the `-P` and `-E` options from the `createuser` command. Also note that the database should be created as UTF8. LATIN1 encoding causes errors trac's use of unicode in trac. SQL_ASCII also seems to work. 73 74 Under some default configurations (debian) one will have run the `createuser` and `createdb` scripts as the `postgres` user. For example: 75 {{{ 76 sudo su - postgres -c 'createuser -U postgres -S -D -R -E -P tracuser' 77 sudo su - postgres -c 'createdb -U postgres -O tracuser -E UTF8 trac' 58 78 }}} 59 79 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.) 80 Trac uses the `public` schema by default but you can specify a different schema in the connection string: 81 {{{ 82 postgres://user:pass@server/database?schema=yourschemaname 83 }}} 84 85 === MySQL Connection String === 86 87 If you want to use MySQL instead, you'll have to use a 88 different connection string. For example, to connect to a MySQL 89 database on the same machine called `trac`, that allows access to the 90 user `johndoe` with the password `letmein`, the mysql connection string is: 91 {{{ 92 mysql://johndoe:letmein@localhost:3306/trac 93 }}} 61 94 62 95 == Source Code Repository == … … 98 131 * `db` 99 132 * `trac.db` - The SQLite database (if you're using SQLite). 100 * `plugins` - Environment-specific [wiki:TracPlugins plugins] (Python eggs) 101 * `templates` - Custom environment-specific templates. 133 * `htdocs` - directory containing web resources, which can be referenced in Genshi templates.
