    55== Creating an Environment == 
    66 
    7 A new Trac environment is created using [wiki:TracAdmin trac-admin]: 
     7A new Trac environment is created using  [wiki:TracAdmin trac-admin]: 
    88{{{ 
    9 $ trac-admin /path/to/projectenv initenv 
     9$ trac-admin /path/to/myproject initenv 
    1010}}}

    1818the appropriate permissions. The same applies to the Subversion repository  
    1919Trac is eventually using, although Trac will only require read access as long  
    20 as you're not using the BDB file system.'' 
     20as you're not using the BDB file system. Also, it seems that project names 
     21with spaces can be problematic for authentication (see [trac:#7163]).'' 
    2122 
    2223== Database Connection Strings == 
    2324 
    24 Since version 0.9, Trac supports both [http://sqlite.org/ SQLite], 
    25 [http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] as 
    26 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. 
     25Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] and 
     26[http://www.postgresql.org/ PostgreSQL] database backends.  Preliminary 
     27support for [http://mysql.com/ MySQL] was added in 0.10.  The default is 
     28to use SQLite, which is probably sufficient for most projects. The database 
     29file is then stored in the environment directory, and can easily be  
     30[wiki:TracBackup backed up] together with the rest of the environment.

     32=== Embedded SQLite Connection String === 
    3133The connection string for an embedded SQLite database is: 
    3234{{{ 
     
    3436}}} 
    3537 
     38=== PostgreSQL Connection String === 
    3639If you want to use PostgreSQL or MySQL instead, you'll have to use a 
    3740different connection string. For example, to connect to a PostgreSQL 
     
    4144postgres://johndoe:letmein@localhost/trac 
    4245}}} 
     46''Note that due to the way the above string is parsed, the "/" and "@" characters cannot be part of the password.'' 
    4347 
    4448If PostgreSQL is running on a non-standard port (for example 9342), use: 
     
    4751}}} 
    4852 
     53On UNIX, you might want to select a UNIX socket for the transport, 
     54either the default socket as defined by the PGHOST environment variable: 
     55{{{ 
     56postgres://user:password@/database 
     57}}} 
     58or a specific one: 
     59{{{ 
     60postgres://user:password@/database?host=/path/to/socket/dir 
     61}}} 
     62 
    4963Note that with PostgreSQL you will have to create the database before running 
    5064`trac-admin initenv`. 
    5165 
    52 And make sure PostgreSQl DB name is "trac". What worked for me: 
    53 And didn't work uppercase trac-user-name 
     66See the [http://www.postgresql.org/docs/ PostgreSQL documentation] for detailed instructions on how to administer [http://postgresql.org PostgreSQL]. 
     67Generally, the following is sufficient to create a database user named `tracuser`, and a database named `trac`. 
    5468{{{ 
    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'; 
     69createuser -U postgres -E -P tracuser 
     70createdb -U postgres -O tracuser -E UTF8 trac 
     71}}} 
     72When 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 
     74Under some default configurations (debian) one will have run the `createuser` and `createdb` scripts as the `postgres` user.  For example: 
     75{{{ 
     76sudo su - postgres -c 'createuser -U postgres -S -D -R -E -P tracuser' 
     77sudo su - postgres -c 'createdb -U postgres -O tracuser -E UTF8 trac' 
    5878}}} 
    5979 
    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.) 
     80Trac uses the `public` schema by default but you can specify a different schema in the connection string: 
     81{{{ 
     82postgres://user:pass@server/database?schema=yourschemaname 
     83}}} 
     84 
     85=== MySQL Connection String === 
     86 
     87If you want to use MySQL instead, you'll have to use a 
     88different connection string. For example, to connect to a MySQL 
     89database on the same machine called `trac`, that allows access to the 
     90user `johndoe` with the password `letmein`, the mysql connection string is: 
     91{{{ 
     92mysql://johndoe:letmein@localhost:3306/trac 
     93}}}
