Web Stack (LAMP)

A LAMP (Linux, Apache, MySQL, PHP) stack is a common web stack used to prepare servers for hosting web content. This guide shows you how to install a LAMP stack an KOOMPI OS.

This guide is written for a non-root user. Commands that require elevated privileges are prefixed with sudo. If you’re not familiar with the sudo command, you can check our Users and Groups guide.

In order to install lamp server, you need to run the command in terminal:

pi -Syu

Don’t forget to update your system before installing this.

Apache Install & Configure

In order to install apache, you have to run command below:

pi -S apache

And then follow the next steps below:

  1. First you need to edit /etc/httpd/conf/httpd.conf file,
  2. sudo nano /etc/httpd/conf/httpd.conf
  3. Then, searchring and commenting out the following line. If it is not commenting, yet
  4. And after that save close files:

Here is the following line, you need to comment:

  #LoadModule unique_id_module modules/mod_unique_id.so

Enable Apache Service

To start your service at boot in http, you can run this command:

systemctl enable httpd

Restart Apache Service

you can restart your serviceon http by:

systemctl restart httpd

Verifying Apache

You can verify whether Apache is running or not with command:

systemctl status httpd

The output of server that we can’t run yet

● httpd.service - Apache Web Server
     Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled)
     Active: inactive (dead)

Output of sample server that is ready to use:

● httpd.service - Apache Web Server

Test Apache

First, Let create a sample page in the Apache root directory. For Example: /srv/http.

nano /srv/http/index.html

Add the following line:

   Welcome to OSTechNix test page


Now, open your web browser and navigate to http://localhost or http://IP-address. You will be pleased with Apache server Test page.

Extent Details

To set Apache to start at boot:

sudo systemctl enable httpd.service

To make a backup:

cp /etc/httpd/conf/extra/httpd-mpm.conf ~/httpd-mpm.conf.backup

Before changing any configuration files, it is advised that you make a backup of the file.

MariaDB Or MySql

Run the following command to install MariaDB:

pi -S mysql

After you run the command above, you will be asked whether to install MariaDB or Percona server, just hit enter and then type “Y” and press enter again. The default selection i.e MariaDB will be installed on your KOOMPI OS and the output will be like this,

[[email protected] ~]$ sudo pacman -S mysql
:: There are 2 providers available for mysql:
:: Repository extra
   1) mariadb
:: Repository community
   2) percona-server

You need to initialize the MariaDB data directory prior to starting the service. To do so, run:

sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

Then issue the following command to enable and start MariaDB service.

systemctl enable mysqld
systemctl start mysqld

You can verify whether MariaDb is running or not using command:

systemctl status mysqld

Setup MySQL/MariaDB root user password

As you may know, It is recommended to setup a password for database root user.

Run the following command to setup MariaDB root user password:


MariaDB has been installed and ready to use. PHP

To install PHP in Arch Linux, run:

pi -S php php-apache

Then PHP is installed, we need to configure Apache PHP module.

To do so, edit /etc/httpd/conf/httpd.conf file,

sudo nano /etc/httpd/conf/httpd.conf

Find the following line and comment it out:

  #LoadModule mpm_event_module modules/mod_mpm_event.so

Then, add the following lines at the bottom, Save and close the file.:

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
LoadModule php7_module modules/libphp7.so
AddHandler php7-script php
Include conf/extra/php7_module.conf

Testing PHP

Now create a test.php file in the Apache root directory.

sudo nano /srv/http/test.php

Add the following lines:


Restart httpd service.

systemctl restart httpd

Open up your web browser and navigate to http://ip-address/test.php
