This page adapts the instructions on Metasploit Wiki:Postgres setup to Fedora.
Starting postgres
user@magnolia:$ sudo -s root@magnolia:$ /etc/init.d/postgresql initdb root@magnolia:$ /etc/init.d/postgresql start
Becoming the postgres user
root@magnolia:# su postgres
Creating a database user
postgres@magnolia:$ createuser msf_user -P Enter password for new role: Enter it again: Shall the new role be a superuser? (y/n) n Shall the new role be allowed to create databases? (y/n) n Shall the new role be allowed to create more new roles? (y/n) n
Allowing password authentication to access postgres on localhost
Edit "/var/lib/pgsql/data/pg_hba.conf", change:
host all all 127.0.0.1/32 ident
to
host all all 127.0.0.1/32 md5

Creating a database
postgres@magnolia:$ createdb --owner=msf_user msf_database
Configure Metasploit
Start the framework, then enter the following commands:
msf> db_driver postgresql msf> db_connect msf_user:yourpassword@127.0.0.1:5432/msf_database msf> db_hosts
Enable the database on startup
$ cat > ~/.msf3/msfconsole.rc db_driver postgresql db_connect msf_user:yourpassword@127.0.0.1:5432/msf_database db_workspace -a MyProject ^D
Troubleshooting
If you run into issues, or need to modify the user or database, you can always use the psql command to do this. Asusming you're using IDENT authentication (default on Fedora and RHEL), you'll have to become the 'postgres' user before you can modify users or databases with psql. (see Becoming the postgres user above)
To list databases
postgres@magnolia:$ psql -l
To assign ownership of a database
To change the owner of a database, pass the following command to psql: "ALTER DATABASE name OWNER TO new_owner" For example:
postgres@magnolia:$ psql -c "ALTER DATABASE msf_database OWNER TO msf_user;"
To add or change the password for a user
To change the password for a postgres user, pass the following command to psql: "ALTER USER username WITH ENCRYPTED PASSWORD 'passwd';" For example:
postgres@magnolia:$ psql -c "ALTER USER msf_user WITH ENCRYPTED PASSWORD 'omgwtfbbq';"
To drop a database
Postgres provides a handy 'dropdb' command.
postgres@magnolia:$ dropdb msf_database
To drop a user
Postgres provides a handy 'dropuser' command.
postgres@magnolia:$ dropuser msf_user
Other useful postgres tips
psql is a handy tool if you need to modify anything inside the postgres system. If you prefer a graphical tool, pgadmin3 is quite good. For more information, see the (extensive) documentation here: http://www.postgresql.org/docs/manuals/
