How Install PostgreSQL database in Ubuntu 9.04

It is very simple to install postgreSQL in Ubuntu. Just run the following command in the command prompt

sudo apt-get install postgresql

This will install the latest postgreSQL and Now your are ready to use it.

But lets do some important configurations (that I did). The PostgreSQL configuration files are stored in the /etc/postgresql//main directory. In my case, I install PostgreSQL 8.3.  So there are in /etc/postgresql/8.3/main

1. Enable TCP/IP connections

By default, connection via TCP/IP is disabled. PostgreSQL supports multiple client authentication methods. By default, IDENT authentication method is used for postgres and local users

To enable TCP/IP connections, edit the file /etc/postgresql/8.3/main/postgresql.conf

Locate the line #listen_addresses = 'localhost'  and uncomment it.

To allow other computers to connect to your PostgreSQL server replace 'localhost' with the IP Address of your server.

2. Set a password for the postgres user


Run the following command at a terminal prompt to connect to the default PostgreSQL template database

 sudo -u postgres psql template1

Then run following SQL command at the psql prompt to configure the password for the user postgres. 

ALTER USER postgres with encrypted password 'your_password';

Remember to restart the PostgreSQL service to initialize the new configuration

Enter the following to restart
 

sudo /etc/init.d/postgresql-8.3 restart
