A LAMP stack is a collection of four different software (Linux, Apache, MySQL, and PHP) that programmers or web developers use to create and deploy websites or applications.
This tutorial will concentrate on how to install and configure the famous LAMP stack with PhpMyAdmin on the last release of RHEL and RHEL-based distributions such as CentOS, Oracle Linux, Rocky, and AlmaLinux.

Depending on the used distribution, use the following links to perform a minimal system installation, using a static IP Address for network configuration.

Step 1: Install Apache Web Server
1. After performing a minimal system installation and configuring your server network interface with a Static IP Address, go ahead and install Apache (httpd) service binary package provided from official repositories using the following yum command.
# yum install httpd
2. After finishing the Apache installation, use the following commands to manage Apache daemon since RHEL and CentOS both migrated their init scripts from SysV to Systemd – Why was init Replaced with Systemd in Linux?.
# systemctl start httpd # systemctl enable httpd # systemctl status httpd
3. On the next step, make sure to allow access to Apache by opening ports 80 and 443 on Firewall using firewall-cmd, which is the default command to manage Firewalld through daemon.
# firewall-cmd --add-service=http # firewall-cmd --add-service=https # systemctl restart firewalld
To apply consistency iptables rules on the firewall using the --permanent option and restart the firewalld service to take effect.
# firewall-cmd --permanent --add-service=http # firewall-cmd --permanent --add-service=https # systemctl restart firewalld
Some important Firewalld commands to manage the firewall as presented below:
# firewall-cmd --state # firewall-cmd --list-all # firewall-cmd --list-interfaces # firewall-cmd --get-service # firewall-cmd --query-service service_name # firewall-cmd --add-port=80/tcp
4. To verify Apache functionality open a remote browser and type your server IP Address using HTTP protocol on the URL, and a default page should appear like in the screenshot below.
http://server_IP
5. For now, the Apache DocumentRoot path it’s set to /var/www/html system path, which by default doesn’t provide any index file. If you want to see a directory list of your DocumentRoot path.
Open the Apache welcome configuration file and set the Indexes statement from – to + on LocationMatch directive, using the below screenshot as an example.
# vi /etc/httpd/conf.d/welcome.conf
6. After making changes, close the file, restart the Apache service to reflect changes, and reload your browser page to see the final result.
# systemctl restart httpd
Step 2: Install PHP Support for Apache
7. Before installing PHP dynamic language support for Apache, get a full list of available PHP modules and extensions using the following command.
# yum search php
8. Depending on what type of applications you want to use, install the required PHP modules from the above list, but for a basic MySQL/MariaDB support in PHP and PhpMyAdmin you need to install the following modules.
# yum install php php-mysql php-pdo php-gd php-mbstring
9. To get a full information list on PHP from your browser, create an info.php file on Apache Document Root using the following command, restart the httpd service, and direct your browser to the http://server_IP/info.php address.
# echo "<?php phpinfo(); ?>" > /var/www/html/info.php # systemctl restart httpd
10. If you get an error on PHP Date and Timezone, open the php.ini configuration file, search, and uncomment date.timezone statement, append your physical location, and restart the Apache daemon.
# vi /etc/php.ini
Locate and change date.timezone line to look like this, using PHP Supported Timezones list.
date.timezone = Continent/City
Step 3: Install and Configure MariaDB Database
11. The RHEL distribution switched from MySQL to MariaDB for its default database management system. To install the MariaDB database use the following command.
# yum install mariadb-server mariadb
12. After the MariaDB package is installed, start the database daemon and use the mysql_secure_installation script to secure the database (set a root password, disable remote login from the root, remove the test database, and remove anonymous users).
# systemctl start mariadb # systemctl enable mariadb # systemctl status mariadb # mysql_secure_installation
13. To test database functionality login to MariaDB using its root account and exit using a quit statement.
mysql -u root -p MariaDB > show databases; MariaDB > quit
Step 4: Install PhpMyAdmin to Manage MySQL
14. By default official repositories don’t provide any binary package for PhpMyAdmin Web Interface. If you are uncomfortable using the MySQL command line to manage your database you can install the PhpMyAdmin package by enabling the remi repository using the following command.
# yum install -y https://rpms.remirepo.net/enterprise/remi-release-9.rpm [On CentOS/RHEL 8] # yum install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm [On CentOS/RHEL 8] # yum install -y https://rpms.remirepo.net/enterprise/remi-release-7.rpm [On CentOS/RHEL 7]
After enabling the remi repository, next install PhpMyAdmin.
# yum install phpmyadmin
15. Next configure PhpMyAdmin to allow connections from remote hosts by editing phpmyadmin.conf file, located on the Apache conf.d directory, commenting on the following lines.
# vi /etc/httpd/conf.d/phpMyAdmin.conf
Add the “Require all granted” line under the “Require local” line as shown.
<Directory /usr/share/phpMyAdmin/> AddDefaultCharset UTF-8 Require local Require all granted </Directory>
16. To be able to log in to the PhpMyAdmin Web interface, restart the Apache Web service and direct your browser to the URL address.
# systemctl restart httpd http://server_IP/phpmyadmin/
Step 5: Enable LAMP System-Wide in Linux
17. If you need MariaDB and Apache services to be automatically started after reboot issue the following commands to enable them system-wide.
# systemctl enable mariadb # systemctl enable httpd
That’s all it takes for a basic LAMP installation on RHEL-based distributions. The next series of articles related to the LAMP stack will discuss how to create Virtual Hosts, generate SSL Certificates and Keys, and add SSL transaction support for Apache HTTP Server.
