How To Install LAMP Stack on CentOS 6

Install LAMP Stack on CentOS 6

In this tutorial, we will show you how to install LAMP Stack on CentOS 6. For those of you who didn’t know, LAMP represents a full-featured stack containing the most popular web server known as Apache, the most popular database server MySQL and the most popular open-source web programming language known as PHP. All components are free and open-source software, and the combination is suitable for building dynamic web pages.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step-by-step installation of LAMP (Linux Apache, MySQL, and PHP) on the CentOS 6 server.

Install LAMP Stack on CentOS 6

Step 1. First of all, make sure that all packages are up to date.

yum -y update

Step 2. Installing Apache on CentOS 6.

We will be installing Apache with yum, which is the default package manager for CentOS 6:

yum install httpd

Start Apache and add it to automatically start on your system start-up using:

chkconfig --levels 235 httpd on
service httpd start

You can verify that Apache is really running by opening your favorite web browser and entering the URL http://your-server's-ip-address and you need to open port 80 to make your web server accessible:

/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/etc/rc.d/init.d/iptables save

Step 3. Installing MySQL on CentOS 6.

Install MySQL with the following command to begin the install:

yum install mysql-server

After that add it to your system startup and start the MySQL server using the following commands:

chkconfig --levels 235 mysqld on
service mysqld start

By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL:

mysql_secure_installation

To log in to MySQL, use the following command (note that it’s the same command you would use to log into a MySQL database):

mysql -u root -p

Step 4. Installing PHP on CentOS 6.

Finally, run the commands below to install PHP along with other good-to-have modules:

yum install php php-mysql

nano /var/www/html/info.php
<?php
phpinfo();
?>
