How to Install PostgreSQL 10 on CentOS 6 / RHEL 6


PostgreSQL is an object-relational database management system (ORDBMS) available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. It is released under the PostgreSQL License, which is a MIT-style license and is thus free and open source software.

PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of community volunteers employed and supervised by companies such as Red Hat and EnterpriseDB. It implements the majority of the SQL:2008 standard, is ACID-compliant, is fully transactional (including all DDL statements), has extensible data types, operators, and indexes, and has a large number of extensions written by third parties.

The vast majority of Linux distributions have PostgreSQL available in supplied packages. Mac OS X starting with Lion has PostgreSQL server as its standard default database in the server edition and PostgreSQL client tools in the desktop edition.

Here is the tutorial about installing PostgreSQL 10 on CentOS 6 / RHEL 6.

Open Terminal ( Applications  —>  System Tools  —> Terminal).

Switch to the root user.

$ su -

Install PostgreSQL 10

PostgreSQL publishes rpm packages for all Linux platforms, and their packages are fresher than those in the other repository. We need to add the repository on our machine by installing repo rpm. 

### 32 Bit ###

# rpm -Uvh

### 64 Bit ###

# rpm -Uvh

Install PostgreSQL 10.

# yum install postgresql10 postgresql10-server

Configure PostgreSQL 10

Initialize the PostgreSQL.

# service postgresql-10 initdb

PostgreSQL normally listens on the localhosts only, if would you like to enable the PostgreSQL to listen on all ip addresses; edit the /var/lib/pgsql/10/data/postgresql.conf .

# vi /var/lib/pgsql/10/data/postgresql.conf

Go to Connections and Communications section, find the “listen_address” variable. Uncomment the “listen_addresses” and place “*” instead of “localhost”

Before editing:

#listen_addresses = "localhost"

After editing:

listen_addresses = "*"

Add your network to access database remotely; Edit /var/lib/pgsql/9.1/data/pg_hba.conf .

# vi /var/lib/pgsql/9.1/data/pg_hba.conf

Add the following line according to your network configuration with md5 password authentication (Enable remote access of database).

# Local networks
host	all	all	     xx.xx.xx.xx/xx	md5
# Example
host	all	all	md5
host    all     all        md5

Restart the PostgreSQL server.

# service postgresql-10 restart
# chkconfig postgresql-10 on

Confirm the PostgreSQL listening.

# netstat -ant | grep 5432
tcp        0      0  *               LISTEN
tcp6       0      0 :::5432                 :::*                    LISTEN

Create Database

Login as postgres user.

# su -l postgres

Create the database called “test”

-bash-4.2$ createdb test

Login into the database.

-bash-4.2$ psql test

Create a new user called “raj” to manage the databases.


Login with the superuser.

$ psql -h dbserver -d test -U raj

That’s All.
