Installing and configuring Postgresql 9.4 on Debian 8

Tags:

Install the postgresql server package:

#apt-get install postgresql-9.4

Create cluster (if it haven't created automatically):

#pg_createcluster 9.4 main --start

Next we need to allow connects from remote sources.

Edit /etc/postgresql/9.4/main/postgresql.conf and set listen_addresses to '*'.

Restart the Postgresql service:

#service postgresql Restart

Now we should create database user.

#su postgres
#psql

postgres=# CREATE USER db_user_name WITH PASSWORD 'secret_password';

Create new database and grant access to it to our user.

postgres=# CREATE DATABASE "db_name"
  WITH OWNER "db_user_name"
  ENCODING 'UTF8'
  LC_COLLATE = 'en_US.UTF-8'
  LC_CTYPE = 'en_US.UTF-8'
  TEMPLATE = template0;

Now we have database with UTF8 collation, it is time to allow connect from remote sources. Our user is the owner of the schema.

Edit /etc/postgresql/9.4/main/pg_hba.conf and add line

host    all   db_user_name    0.0.0.0/0               md5

after the line:

host    all   all             127.0.0.1/32            md5

Save file and restart the service.

Now we can connect to our server from remote computer.
