How to Install LAMP Stack on Rocky Linux 9

A LAMP stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is actually an acronym that represents the Linux operating system, with the Apache web server. The site data is stored in a MySQL database, and dynamic content is processed by PHP.

Pre-requisites :

  • A system with Rocky Linux 9 installed and running.

  • root access to the system.

Install Apache Web Server

First, we will start by installing the Apache web server. To complete the installation, use the following command.

yum install httpd httpd-tools

Output:

[root@server ~]# yum install httpd httpd-tools

Once the installation is complete, enable Apache (to start automatically upon system boot), start the web server and verify the status using the commands below.

systemctl enable httpd

systemctl start httpd

systemctl status httpd

Output:

To make your pages available to the public, you will have to edit your firewall rules to allow HTTP and HTTPS requests on your web server by using the following commands.

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

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

firewall-cmd --reload

Output:

[root@server ~]# firewall-cmd --permanent --zone=public --add-service=http
success
[root@server ~]# firewall-cmd --permanent --zone=public --add-service=https
success
[root@server ~]# firewall-cmd --reload
success

Verify that the web server is running and accessible by accessing your server’s IP address.

echo "Hello there, Apache webserver is now running" > /var/www/html/index.html

And restart the Web Server to reflect the changes made.

systemctl restart httpd

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

To install yum utilities.

yum -y install yum-utils

To install remaining updates

yum update

To install PHP along with a few commonly used PHP extensions on your Rocky Linux 9 use the command below.

yum install -y php php-zip php-intl php-mysqlnd php-dom php-simplexml php-xml php-xmlreader php-curl php-exif php-ftp php-gd php-iconv php-json php-mbstring php-posix php-sockets php-tokenizer

Check PHP Version.

php -v

Once the installation is complete, enable MariaDB (to start automatically upon system boot), start the MariaDB, and verify the status using the commands below.

systemctl enable mariadb

systemctl start mariadb

systemctl status mariadb

Finally, you will want to secure your MariaDB installation by issuing the following command.

mysql_secure_installation

Output:

[root@server ~]# mysql_secure_installation

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):
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:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

Once secured, you can connect to MySQL and review the existing databases on your database server by using the following command.

mysql -e "SHOW DATABASES;" -p

Output:

[root@server ~]# mysql -e "SHOW DATABASES;" -p
Enter password:
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
+--------------------+

Done!
