• PostgreSQL server version 7.4 or above must be running either on the local machine or remotely over a TCP/IP port. You should use the --locale=C option when initializing the server with initdb.

• Create user accounts.

• Configure access privileges.

• Restart PostgreSQL server.

• [Linux] Open a shell as user postgres. E.g.

[user@localhost]$ su
[root@localhost]$ su postgres
[postgres@localhost]$

• Create a database user lexdb who will manage the database. E.g. [Linux]

{{{[postgres@localhost]$ createuser -U postgres --createdb --no-adduser lexdb CREATE USER}}}

• [Optional] If you wish to use password authentication add the -P option.

• Create a user account for yourself (substitute your shell login for USERNAME below). E.g. [Linux]

{{{[postgres@localhost]$ createuser -U postgres --no-createdb --no-adduser USERNAME CREATE USER}}}

• [Optional] If you wish to use password authentication add the -P option.

• Ensure the access privilege configuration file [Linux] $PGDATA/pg_hba.conf contains the following lines:

{{{# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

local all all trust host all all 127.0.0.1 255.255.255.255 trust}}}

• [Optional] If you wish to use password authentication replace trust with md5.

• TCP/IP must be enabled. Uncomment the line for TCP/IP in [Linux] $PGDATA/postgresql.conf so that it reads:

     tcpip_socket = true

• By default the server will run on port 5432. To use another port set the PSQL environment variable PGPORT.

• Allow remote access to the server by adding lines of the following form to access privilege configuration file [Linux] $PGDATA/pg_hba.conf:

host    all         all        IP_ADDRESS    255.255.255.255     md5

• [Optional] If you wish to use password authentication replace trust with md5.

• TCP/IP must be enabled. Uncomment the line for TCP/IP in [Linux] $PGDATA/postgresql.conf so that it reads:

     tcpip_socket = true

• By default the server will run on port 5432. To use another port set the environment variable PGPORT.
