How to Install LAMP Stack on AlmaLinux 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 which 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.

Install Apache Web Server

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

dnf install httpd httpd-tools


[root@server ~]# dnf 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


[root@server ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server
     Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

       Docs: man:httpd.service(8)
   Main PID: 1085 (httpd)
     Status: "Total requests: 0; Idle/Busy workers 100/0;Requests/sec: 0; Bytes served/sec:   0 B/sec"

             ├─1086 /usr/sbin/httpd -DFOREGROUND
             ├─1087 /usr/sbin/httpd -DFOREGROUND

To make your pages available to 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


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

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

And restart tht Web Server to reflect the changes made.

systemctl restart httpd

From your browser,


Replace the IP_address with the actual IP address.


Install PHP

If you would like to install a different version of PHP from remi repository, please refer Install PHP wiki.

We will install the EPEL Repository,

rpm -Uvh

To install PHP on AlmaLinux, use the command below.

dnf install php

We will need other PHP modules as well,

yum install -y 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

Now restart your web server so that Apache knows that it will be serving PHP requests as well.

systemctl restart httpd 

Test your PHP, by creating a simple info.php file with a phinfo() in it. The file should be placed in the directory root for your web server, which is /var/www/html.

To create the file use:

echo "<?php phpinfo() ?>" > /var/www/html/info.php

Now again, access http://localhost/info.php or http://yourserver-ip-address/info.php. You should see a page similar to below one.


Install MariaDB Server

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

dnf install mariadb-server mariadb


[root@server ~]# dnf install mariadb-server mariadb

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


[root@server ~]# systemctl status mariadb
● mariadb.service - MariaDB 10.5 database server
     Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)
     Active: active (running) since Fri 2022-05-20 18:07:30 CEST; 4s ago

    Process: 6665 ExecStartPost=/usr/libexec/mariadb-check-upgrade (code=exited, status=0/SUCCESS)
   Main PID: 6653 (mariadbd)

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



[root@server ~]# 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):
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


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