LAMP is a complete package to run any web application on a server. LAMP signifies the Linux, Apache HTTP,  MariaDB and Php. Apache HTTP is used as the web server for hosting of an application whereas MariaDB is used as systematic data storage of application & Php is popular server-side scripting language which is used for web development as well bridging the gap between application and the database.

Step 5. Install MariaDB in your Machine by running bellow command from your terminal.

# yum install mariadb-server -y

Step 6. Start MariaDB Service.

# service mariadb start

Step 7. Configure MariaDB server by using below command.

# mysql_secure_installation

In order to log into MariaDB to secure it, we’ll need the current password for the root user. If you’ve just installed MariaDB, and you haven’t set the root password yet, the password will be blank, so you should just press enter here.

Enter current password for root (enter for none):

Note: – Press Enter to proceed further.
  
OK, successfully used password, moving on…Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation.


Set root password? [Y/n] y


New password:  
                               Specify New Password for MariaDB

Re-enter new password:              Confirm Password by specifying again
 
Password updated successfully!
Reloading privilege tables..
… Success!
By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a production environment.
  
Remove anonymous users? [Y/n] y
… Success!Normally, root should only be allowed to connect from ‘localhost’. This ensures that someone cannot guess at the root password from the network.
  
Disallow root login remotely? [Y/n] y

… Success!By default, MariaDB comes with a database named ‘test’ that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.
 
Remove test database and access to it? [Y/n] y

– Dropping test database…
… Success!
– Removing privileges on test database…
… Success!Reloading the privilege tables will ensure that all changes made so far will take effect immediately.
 
Reload privilege tables now? [Y/n] y
… Success!Cleaning up…All done! If you’ve completed all of the above steps, your MariaDB installation should now be secure.
Thanks for using MariaDB!

Step 8.  Execute below lines to get PHP 7 Repository in your system.

# yum install epel-release -y
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
# rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

Step 9. Install Php 7 by running bellow command from your terminal.

# yum install php70w php70w-mbstring php70w-json php70w-gd php70w-mcrypt php70w-mysql -y

Step 10. The document root of the webserver is /var/www/html. Now we will create  PHP file (info.php) in  /var/www/html/ directory and call it through a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.

# vi /var/www/html/info.php

<?php
phpinfo();
?>

Step 11.Restart Web Server.

# service httpd restart

Step 12. Finish up by visiting your php info page.The page should look like this.

http://ip/info.php
