PostgreSQL is an open-supply relational database control system that has helped to form the sector of software improvement with advanced, SQL-compliant. The fundamental gain of the use of PostgreSQL is that it calls for very minimal preservation efforts due to its stability. The programs primarily based totally on PostgreSQL have a low value of possession in assessment with different database control systems. It’s designed to be extensible in a manner that you could outline your very own records types, index types, functional languages, etc. PhpPgAdmin is a web-primarily based totally GUI software that makes it easy for administering your PostgreSQL databases. phpPgAdmin will allow you to add, cast off and manipulate databases, tables, and entries; run particular SQL queries, backup the database, search and import record, and lots more. In this educational we discover ways to deploy phpPgAdmin on CentOS 7.
Before beginning the set up of PotgreSQL and phpPgAdmin ensure which you have root get entry to in your CentOS server and your are linked to the internet for downloading the packages. After login in your server, run the command under to replace your centos 7 server with the state-of-the-art patches.
# yum update
If you going to install PostgreSQL and phpPgAdmin on a production surroundings with firewall and SELinux enabled, then ensure to permit the subsequent default ports in order to be used for postgreSQL and apache.
# firewall-cmd --permanent --add-port=5432/tcp # firewall-cmd --permanent --add-port=80/tcp # firewall-cmd --reload
# setsebool -P httpd_can_network_connect_db 1
Let’s begin the Installation
By default Centos 7 comes with PostgreSQL Version 9.2.1 that may be set up with the aid of using the usage of the easy yum command whilst the contemporary latest PostgreSQL Version is 9.4.5. So, on this tutorial, we are able to be putting in the latest model of PostgreSQL by the usage of the PostgreSQL Yum Repository. To get the latest yum repository for the latest PostgreSQL package deal open the PostgreSQL Download Page or copy the hyperlink and run the under wget command.
# wget http://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-redhat94-9.4-1.noarch.rpm
Now install the rpm file with below commands
# rpm -i pgdg-redhat94-9.4-1.noarch.rpm # yum install postgresql94-server postgresql94-contrib
After jogging the above command there might be variety of the subsequent package might be established consisting of few dependencies. To continue the set up technique press the “Y” key to maintain as shown.

run the below command to initialize the database

Start the Database service
To begin the PostgreSQL provider and to configure it for auto-permit at boot up run the subsequent commands after which test the status, it must be up and enabled.
# systemctl start postgresql-9.4 # systemctl enable postgresql-9.4
Now install the phpPgAdmin
Run the below command to install phpPgAdmin and http
yum install phpPgAdmin httpd

Now don’t think too much and do as I say. But be careful if you are on production server
# vim /etc/httpd/conf.d/phpPgAdmin.conf
# vim /var/lib/pgsql/9.4/data/pg_hba.conf
# vim /var/lib/pgsql/9.4/data/postgresql.conf
# vim /etc/phpPgAdmin/config.inc.php
// Hostname or IP address for server. Use '' for UNIX domain socket. // use 'localhost' for TCP/IP connection on this computer $conf['servers']['host'] = 'localhost'; // Database port on server (5432 is the PostgreSQL default) $conf['servers']['port'] = 5432; $conf['owned_only'] = true;
Now restart the both services
# systemctl restart postgresql-9.4 # systemctl restart httpd
Access the web console
Let’s open the below URL to access the phpPgAdmin console as shown below.
Now login with your DB and password…
