PostgreSQL (pronounced “post-gress-Q-L”). PostgreSQL is an open source object-relational database system. It is powerful and highly scalable SQL-compliant database management system. It is developed at the University of Califonia at Berkeley Computer Science Department.

In this article I will describe how you can install PostgreSQL 10 on CentOS/RHEL and Fedora 26/25 system.

Install PostgreSQL Repository

First of all you have to install PostgreSQL yum repository on your system. To install PostgreSQL yum repository type the below command:

On CentOS/RHEL - 7
# rpm -Uvh

On CentOS/RHEL - 6
# rpm -Uvh

PostgreSQL 10 Installation

After installing PostgreSQL repository on your system, type the below command to install the PostgreSQL 10:

# yum install postgresql10-server postgresql10

Initialize PGDATA

If you are using PostgreSQL first time it is require to initialize it. Type the below command to do this:

# /usr/pgsql-10/bin/postgresql-10-setup initdb

It will take some time to initialize your PostgreSQL. PGDATA environment variable contains the path of data directory.

Default PostgreSQL data directory path is : /var/lib/pgsql/10/data/

Start PostgreSQL Server

Now start your PostgreSQL server typing below command and enable PostgreSQL service at the system boot time.

For CentOS/RHEL 7 and Fedora

# systemctl start postgresql-10.service
# systemctl enable postgresql-10.service

For CentOS/RHEL 6

# service postgresql-10 start
# chkconfig postgresql-10 on

Verify PostgreSQL Server Installation

After installing PostgreSQL server on system now lets login to access it:

# su - postgres -c "psql"

psql (10.0)
Type "help" for help.

You can also create password for user postgres for security purpose.
