Configure Postgresql for my Rails Application

Hi there, This post I want to write as a log of my success on configuring Postgresql database to production for my Rails application.

Let’s get started. I’ve installed Postgresql 8.4 through apt-get.

The first step I do is to change the password of ‘postgres’ user.

Run the command on root shell.

 passwd postgres 

And I usually allow remote access into my Postgresql database. So, I have to edit the file ‘/etc/postgresql/8.4/main/pg_hba.conf’ by seeing this line.

 local all all ident 

and change it to…

 local all all md5 

Then restart the service.

 /etc/init.d/postgresql-8.4 restart 

The second step I usually do is to install the admin pack.

 su - postgres psql template1 < /usr/share/postgresql/8.4/contrib/adminpack.sql psql -d template1 -c "ALTER USER postgres WITH PASSWORD 'newpassword';" 

The next step is to create a new database and user to be used by your application. Assume the application is named ‘Social Dating’.

 createdb socialdatingdb createuser socialdatinguser --pwprompt psql socialdatingdb GRANT ALL TO socialdatinguser 

Then you can test CRUD on the database with…

 psql -U socialdatinguser -W socialdatingdb 

Enjoy Postgresql!
