More about LAMP
LAMP is nothing but a software bundle or a platform consisting of Linux operating system, Apache web-server, MySQL database server and PHP (or Perl/Python)scripting language. The LAMP stack is used for building heavy-duty dynamic web sites entirely out of free and open-source software. In this tutorial, I'm going to explain how to Linux, Apache, MySQL/MariaDB (drop in replacement for MySQL), PHP (LAMP) stack On CentOS 7 or RHEL 7.
Assumptions
- I'm assuming that you've installed basic RHEL 7 or CentOS 7 server. Open the Terminal app and type the following command as root user.
- You must be familiar with the yum command
- You must know your Server's IP address. Use the following command to find your server's ip address for eth0 interface:
ifconfig eth0
OR
ip a show eth0
OR
ip addr list eth0 | awk '/inet /{sub(/\/[0-9]+/,"",$2); print $2}'
OR
ifconfig eth0 | awk '/inet /{print $2}'
10.41.143.156 - I'm going to use IP address 10.41.143.156 for testing purpose. Feel free to replace this IP address with your actual private or public IP address.
Enough talk, let's set up LAMP stack.
Step #1: Install Apache on a CentOS 7 / RHEL 7 server

Enable the httpd service at boot time
To make sure the httpd service start automatically at the boot time, enter:
Sample outputs:
sudo systemctl enable httpd.service
Sample outputs:
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
The following command will disable the httpd service at the boot time:
Sample outputs:
sudo systemctl disable httpd.service
Sample outputs:
rm '/etc/systemd/system/multi-user.target.wants/httpd.service'
Start the httpd service on a CentOS/RHEL v7.x
sudo systemctl start httpd.service
At this stage, you can point your web-browser to your server's IP address such as http://10.41.143.156). The following page should display on screen:
Stop the httpd service on a CentOS/RHEL v7.x
sudo systemctl stop httpd.service
Restart the httpd service on a CentOS/RHEL v7.x
sudo systemctl restart httpd.service
Finding the httpd service status on a CentOS/RHEL v7.x
To verify that the httpd service is running, enter:
Sample outputs:
systemctl is-active httpd.service
Sample outputs:
active
Gracefully restart the httpd service on a CentOS/RHEL v7.x
sudo apachectl graceful
Test httpd/Apache configuration file for errors on a CentOS/RHEL v7.x
sudo apachectl configtest
Sample outputs:
Syntax OK
httpd service default configuration
- Default config file: /etc/httpd/conf/httpd.conf
- Configuration files which load modules : /etc/httpd/conf.modules.d/ directory (e.g. PHP)
- Select MPMs (Processing Model) as loadable modules [worker, prefork (default)] and event:/etc/httpd/conf.modules.d/00-mpm.conf
- Default ports: 80 and 443 (SSL)
- Default log files: /var/log/httpd/{access_log,error_log}
Step #2: Install MariaDB on a CentOS 7 / RHEL 7 server
MariaDB An enhanced, drop-in replacement for MySQL server. RHEL/CentOS v7.x shifts from MySQL to MariaDB for its database management system needs. Type the following yum command to install MariaDB server:
To start mariadb, type:
To make sure the mariadb service start automatically at the boot time, enter:
Sample outputs:
sudo yum install mariadb-server mariadb
To start mariadb, type:
sudo systemctl start mariadb.service
To make sure the mariadb service start automatically at the boot time, enter:
sudo systemctl enable mariadb.service
Sample outputs:
ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'
To stop/restart and disable mariadb service use the following commands:
sudo systemctl stop mariadb.service #<-- Stop mariadb server sudo systemctl restart mariadb.service #<-- Restart mariadb server sudo systemctl disable mariadb.service #<-- Disable mariadb server sudo systemctl is-active mariadb.service #<-- Is mariadb server running?
Securing MariaDB
Type the following command:
Sample outputs:
sudo /usr/bin/mysql_secure_installation
Sample outputs:
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! 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): PRESS-ENTER-KEY 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: YOUR-NEW-PASSWORD-HERE Re-enter new password: YOUR-NEW-PASSWORD-HERE 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!
Test MariaDB installation
Type the following command
Sample outputs:
mysql -u root -p
Sample outputs:
Step #3: Install PHP on a CentOS/RHEL v7.x
To install PHP and modules such as gd/msyql type the following yum command:
You must restart the httpd (Apache) service, enter:
To search all other php modules, type:
Sample outputs:
sudo yum install php php-mysql php-gd php-pear
You must restart the httpd (Apache) service, enter:
sudo systemctl restart httpd.service
To search all other php modules, type:
sudo yum search php-
Sample outputs:
php-cli.x86_64 : Command-line interface for PHP php-common.x86_64 : Common files for PHP php-gd.x86_64 : A module for PHP applications for using the gd graphics library php-ldap.x86_64 : A module for PHP applications that use LDAP php-mysql.x86_64 : A module for PHP applications that use MySQL databases php-odbc.x86_64 : A module for PHP applications that use ODBC databases php-pdo.x86_64 : A database access abstraction module for PHP applications php-pear.noarch : PHP Extension and Application Repository framework php-pecl-memcache.x86_64 : Extension to work with the Memcached caching daemon php-pgsql.x86_64 : A PostgreSQL database module for PHP php-process.x86_64 : Modules for PHP script using system process interfaces php-recode.x86_64 : A module for PHP applications for using the recode library php-soap.x86_64 : A module for PHP applications that use the SOAP protocol php-xml.x86_64 : A module for PHP applications which use XML php-xmlrpc.x86_64 : A module for PHP applications which use the XML-RPC protocol
To find more info about a module type:
To install php module called php-pgsql type:
sudo yum info php-pgsql
To install php module called php-pgsql type:
sudo yum install php-pgsql
Test PHP on your server
Create a file called /var/www/html/test.php as follows:
Append the following code:
sudo vi /var/www/html/test.php
Append the following code:
<?php phpinfo(INFO_GENERAL); ?>
Save and close the file. Point your web-browser to your server's IP address such as http://10.41.143.156/test.php (feel free to replace the 10.41.143.156 with your actual IP address):
http://10.41.143.156/test.php
Sample outputs:
