In this article, we will examine the installation of PostgreSQL on linux, which attracts attention with its large-scale data management and increases the market share in the last years.
We will perform RPM based installation for enterprise linux based systems such as RedHat / Centos / Scientefic. In addition, we will compile from generic source code.
Installation on Redhat
|
1 2 3 |
yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-redhat10-10-2.noarch.rpm yum install postgresql10 yum install postgresql10-server |
The following commands are executed to start Postgres and open it automatically on boot progress.
|
1 2 3 |
/usr/pgsql-10/bin/postgresql-10-setup initdb systemctl enable postgresql-10 systemctl start postgresql-10 |
Installation completed then we can connect to postgresql now. To check whether it is runing properly or not you can execute following commands. (5432 default TCP port for postgreSQL)

[root@yesrib ~]# netstat -ntlp |grep 5432 tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 17795/postmaster tcp6 0 0 :::5432 :::* LISTEN 17795/postmaster sudo su - postgres -bash-4.2$ psql psql (10.3) Type "help" for help. |

Success. You can now start the database server using:
