How To Install LEMP Stack on AlmaLinux 8

Install LEMP Stack on AlmaLinux 8

In this tutorial, we will show you how to install LEMP Stack on AlmaLinux 8. For those of you who didn’t know, LEMP is a combination of free, open-source software. The acronym LEMP refers to the first letters of Linux (Operating system), Nginx Server, MySQL (database software), and PHP principal components to build a viable general-purpose webserver.

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 and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the LEMP Stack on an AlmaLinux 8.

Install LEMP Stack on AlmaLinux 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update
sudo dnf install epel-release

Step 2. Installing Nginx on AlmaLinux 8.

Now we run the following command to install the Nginx webserver:

sudo dnf install nginx

Once it is installed, you can start and enable the Nginx service using the following command:

sudo systemctl start nginx
sudo systemctl enable nginx

Check Nginx version:

nginx -v

Next, verify that the webserver is running and accessible by accessing your server’s IP address:

http://your-server-ipadress

Step 3. Installing MariaDB on AlmaLinux 8.

MariaDB is a popular database server. The installation is simple and requires just a few steps as shown:

sudo dnf install mariadb-server mariadb

Once the installation is complete, start to enable it to start on system start-up using:

sudo systemctl restart mariadb
sudo systemctl status mariadb
sudo systemctl enable mariadb

By default, MariaDB is not hardened. You can secure MariaDB 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 MariaDB:

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

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

mysql -u root -p

Step 4. Installing PHP on AlmaLinux 8.

To Install PHP-FPM by running the following command:

sudo dnf install php php-mysqlnd php-fpm php-opcache php-gd php-xml php-mbstring

Once the installation is complete, start and enable php-fpm to start on boot with the below commands:

sudo systemctl start php-fpm
sudo systemctl enable php-fpm

By default, PHP-FPM runs as the apache user. Since we are using an Nginx web server, we need to change the following line:

$ nano /etc/php-fpm.d/www.conf

user = apache
group = apache

Change them to:

user = nginx
group = nginx

Save the file and restart both Nginx and PHP-FPM for the changes to come into effect:

sudo systemctl restart nginx
sudo systemctl restart php-fpm

To test the PHP installation, creating an info.php file in the /usr/share/nginx/html/ path:

sudo nano /usr/share/nginx/html/info.php

Append the following lines and save the file:

<?php
phpinfo();
?>

That’s it, now you can access it using your server IP:

http://your-ip-address/info.php

Step 5. Configure Firewall.

Now we add HTTP and HTTPS ports in firewall using the following command:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Congratulations! You have successfully installed LEMP. Thanks for using this tutorial for installing LEMP (Nginx, MariaDB, and PHP) Stack on your AlmaLinux 8 system. For additional help or useful information, we recommend you check the official LAMP website.
