PostgreSQL configuration for VHFFS
VHFFS needs a PostgreSQL database to store its data. We urge you to learn how to use PostgreSQL, because you are going to use it a lot along with VHFFS.
# apt-get install postgresql
# su - postgres -c "createuser -P vhffs" 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
su - postgres -c "createdb -O vhffs vhffs"
root@vhffs:~# su - postgres postgres@vhffs:~$ psql postgres=# \l List of databases Name | Owner | Encoding | Collation | Ctype | Access privileges -----------+----------+----------+-------------+-------------+----------------------- [...] vhffs | vhffs | UTF8 | en_US.UTF-8 | en_US.UTF-8 | (4 rows)
If not, you have to create a new PostgreSQL cluster with the UTF-8 encoding. If the VHFFS database was the only database of the previous cluster not using UTF8, you can of course destroy the cluster.
Having several PostgreSQL clusters running will change slightly the psql command lines along this guide, but we consider that if you need several clusters that you know what you are doing and know what you need to change.
Configure the file
/etc/postgresql/8.4/main/pg_hba.conf to allow the vhffs user to access the vhffs database. By default localhost is allowed to connect to all databases using a password auth.
Then, initialize the database:
~/vhffs-4.4# psql vhffs vhffs -h localhost Password for user vhffs: psql (8.4.7) SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256) Type "help" for help. vhffs=> \i vhffs-backend/src/pgsql/initdb.sql
