How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Arch Linux

About LAMP

The LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache, MySQL, and PHP. Arch Linux uses the powerful Pacman installer which can download all of the most recent, required packages for each program with one command.

Set Up

The steps in this tutorial require the user to have root privileges. You can see how to set that up here in steps 3 and 4.

Step One—Install Apache

Apache is a free open source software that runs over 50% of the world’s web servers.

Before installing any of the LAMP programs, we should update the package manager:

sudo pacman -Syu

Once the update is complete, we can install Apache:

sudo pacman -S apache

After Apache is installed, we need to make a couple of changes in the configuration.

Open up the apache configuration file:

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

Comment out the unique_id_module (you can use ctrl w to find it quickly):

#LoadModule unique_id_module modules/mod_unique_id.so

Restart Apache:

sudo systemctl restart httpd

During the apache restart, you may get a notice that says the following:

httpd: apr_sockaddr_info_get() failed for droplet1
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
                                                                         [DONE]

Although this alert does not interfere with the apache launch, you can easily eliminate it if you like by adding your hostname to your configuration.

Open up the hosts file:

sudo nano /etc/hosts

Add your hostname to the end of the line beginning with 127.0.0.1:

127.0.0.1       localhost.localdomain   localhost droplet1

Subsequent restarts of Apache will no longer display that message. With that, Apache is now installed on your server. Directing your browser to your server’s IP address (http://12.34.56.789) will display an auto-index directory. You can quickly try out a sample page by adding an index.html file to Arch’s document root directory, located within “srv/http”:

sudo nano /srv/http/index.html
<html>
<title>Welcome</title>
<body>
<h2>Hello, Welcome to Arch</h2>
</body>
</html>

You can visit the placeholder page by going to your server’s IP address in your browser.

How to Find your Server’s IP address

You can run the following command to reveal your server’s IP address.

curl -s icanhazip.com

Step Two—Install MySQL

MySQL is a powerful database management system used for organizing and retrieving data.

Since March 2013, MariaDB has become the default implementation of MySQL in Arch repositories. Installing the package "mysql" will automatically drop in MariaDB as a replacement. See the original announcement for more details.

To install MySQL, open terminal and type in these commands:

sudo pacman -S mysql

Hit enter if it asks you anything, unless you know you don't want the defaults.

Once you have installed MySQL, start it running

sudo systemctl start mysqld

Finish up by running the MySQL set up script:

sudo mysql_secure_installation

The process will ask you for your current MySQL root password (not to be confused with your server password) and, since it has not yet been set, simply press enter.

When prompted, “Set root password?” type Y, and afterwards enter in your new MySQL root password.

After that it’s easiest just to say Yes to all the options. At the end, MySQL will reload and implement the new changes.

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y                                            
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

Once you're done installing MySQL, finish the LAMP stack by installing PHP.

Step Three—Install PHP

PHP is an open source web scripting language that is widely used to build dynamic webpages.

To install PHP, open terminal and type in this command.

sudo pacman -S php php-apache

PHP should also be added to the apache configuration file:

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

Paste in this text block within the config.

# Use for PHP 5.x:
LoadModule php5_module       modules/libphp5.so
AddHandler php5-script php
Include conf/extra/php5_module.conf

Step Four—See your PHP Config and Add Programs to Startup

After LAMP is completely installed, we can take a look and see the PHP details by creating a quick php info page

To set this up, first create a new blank file:

sudo nano /srv/http/info.php

Add in the following line:

<?php
phpinfo();
?>

Then Save and Exit.

Restart apache so that all of the changes take effect:

sudo systemctl restart httpd

Visit your php info page (make sure you replace the example ip address with your correct one): http://12.34.56.789/info.php

Your screen should then look like this:

PHP info

To close out the LAMP installation, open up the configuration file of Arch’s innitscripts and add the apache server and MySQL daemons to the list of programs that run upon server startup:

sudo systemctl enable mysqld httpd

Congratulations, you have now installed the LAMP server on Arch Linux!

On Manjaro (I don’t know if it applies to another Arch distro) when you install MySQL (MariaDB) you cannot directly start the dbms via sudo systemctl start mysqld. Previous to do it, you’ll need to run mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql to create the MySQL tables in the corresponding directory.

After that, follow the guide as normal.

As of recent using MariaDb in Arch it is importan to install and initialize MariaDB date directory using $ sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

before running sudo mysql_secure_installation

UPDATE for PHP7 In /etc/httpd/conf/httpd.conf, comment the line: #LoadModule mpm_event_module modules/mod_mpm_event.so

and uncomment the line: LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

The above is required, because libphp7.so included with php-apache does not work with mod_mpm_event, but will only work mod_mpm_prefork instead.

Then replace:


Use for PHP 5.x:

LoadModule php5_module modules/libphp5.so AddHandler php5-script php Include conf/extra/php5_module.conf


With


Use for PHP 7.x:

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


REF: https://wiki.archlinux.org/index.php/Apache_HTTP_Server#PHP

In the instalation’s step of mariadb before run the command “sudo systemctl start mysqld” gone need run “mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql” . Tried run without it but no work. I’m using Antergos Linux 64-bit

Thank you!

Hi ,

I installed apache http server and everything going well. I’m using Sublime Text 2 as my text editor.So when i going to save some file after editing it with sublime text it says that "Unable to save file to /svr/http/*** " … I think it happening beacaus of permission problem. I’m using my pc as a normal user (not as the root).how can i solve this.

Thanks !

@mirzalazuardi @asb Having same issue, only difference is:

[root@x]# systemctl status httpd.service
● httpd.service - Apache Web Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; ***disabled***)
apachectl configtest

Comes back clean.

I’ve isolated it to only the line

LoadModule php5_module       modules/libphp5.so

Edit: Weird so I ran configtest again and I got an error: “Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe.” Easy fix:

/etc/httpd/conf/httpd.conf
# This line was causing problems, comment it or remove:
# LoadModule mpm_event_module modules/mod_mpm_event.so

# Add in this line:
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

arch wiki

@mirzalazuardi: Run apachectl configtest It should give you an idea of what the issue might be.

why my apache wont running after added line?

LoadModule php5_module modules/libphp5.so AddHandler php5-script php Include conf/extra/php5_module.conf

here error messages :

[luckymeerza@hostname ~]$ sudo systemctl restart httpd Job for httpd.service failed. See ‘systemctl status httpd.service’ and ‘journalctl -xn’ for details.

if I remove those 3 lines, apache running well, but apache doesnt interpret my php file.

Thanks, hoping for your support
