Step 1 – Enable Yum Repository

The two most popular rpm repositories REMI and EPEL have most of the updated packages. They are also providing the latest packages for LAMP setup. Enable both repositories on your system using the following commands on your CentOS 7 system.

rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

Step 2 – Install Apache Server

Apache or HTTP is the most popular web server used on Linux based systems. Let’s install Apache web server using the following command by enabling EPEL and REMI yum repositories.

yum --enablerepo=epel,remi install httpd

Now start httpd service and enable to start on boot using commands.

systemctl start httpd.service
systemctl enable httpd.service

Step 3 – Install MySQL Server

First add MySQL yum repository in your system using the following command. You may also visit repo.mysql.com to find repository rpms for other operating systems. The below command will work with CentOS and RedHat 7.

rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

Now install MySQL server and other dependency packages.

yum install mysql-server

The installer generated a temporary password for MySQL root user and copied to log file. You can find this password using the below command.

# grep "A temporary password" /var/log/mysqld.log  | tail -n1

Apply security on newly installed MySQL server. This will also prompt you to change the temporary password with new password.

systemctl start mysqld.service
mysql_secure_installation

Now restart MySQL service and enable to start on system boot.

systemctl restart mysqld.service
systemctl enable mysqld.service

Step 4 – Install PHP

Now install php packages with enabling epel and remi repositories using following command.

yum --enablerepo=epel,remi-php71 install php

Now install required php modules. Use following command to list available modules and install it.

yum --enablerepo=epel,remi-php71 list php-*
 yum install php-mysql php-xml php-xmlrpc php-soap php-pgsql php-gd

After installing php and other php modules restart Apache service.

systemctl restart httpd.service

Step 5 – Allow Port in Firewall

Finally open firewall ports for HTTP (80) and HTTPS (443) services using the following command.

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Step 6 – Check Installed Version

Let’s check the installed versions of packages on the system using following commands one by one.

php -v

PHP 7.1.11 (cli) (built: Oct 25 2017 10:24:28) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

httpd -v

Server version: Apache/2.4.6 (CentOS)
Server built:   Oct 19 2017 20:39:16

mysql -V

mysql  Ver 14.14 Distrib 5.7.20, for Linux (x86_64) using  EditLine wrapper

Now you have successfully configured LAMP setup on your CentOS or RedHat 7 system.
