How to Install a LAMP Stack on Arch Linux
Updated by Alex Fornuto Written by Alex Fornuto
Install and Configure LAMP (Linux, Apache, MySQL, PHP) on an Arch Linux Server
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 Arch Linux server.
Since Arch does not come in specific versions, this guide is up-to-date as of the December 2015 Arch update.
NoteThis guide is written for a non-root user. Commands that require elevated privileges are prefixed with
sudo. If you’re not familiar with the
sudocommand, you can check our Users and Groups guide.
Before You Begin
Update your system:
sudo pacman -Syu
Install and Configure
Install Apache 2.4:
sudo pacman -Syu apache
httpd-mpm.confApache configuration file in
/etc/httpd/conf/extra/to adjust the resource use settings. The settings shown below are a good starting point for a Linode 2GB:
Before changing any configuration files, it is advised that you make a backup of the file. To make a backup:
cp /etc/httpd/conf/extra/httpd-mpm.conf ~/httpd-mpm.conf.backup
1 2 3 4 5 6 7
<IfModule mpm_prefork_module> StartServers 4 MinSpareServers 20 MaxSpareServers 40 MaxRequestWorkers 200 MaxConnectionsPerChild 4500 </IfModule>
httpd-default.conffile to turn KeepAlive off.
Set Apache to start at boot:
sudo systemctl enable httpd.service
Add Name-Based Virtual Hosts
Virtual hosting can be configured so that multiple domains (or subdomains) can be hosted on the server. These websites can be controlled by different users, or by a single user, as you prefer. There are different ways to set up virtual hosts; however, we recommend the method below.
httpd.confand edit the line
DocumentRoot /srv/httpto define the default document root:
Uncomment the line that reads
Include conf/extra/httpd-vhosts.confnear the end of the
httpd-vhosts.conf, under the
extrafolder. Edit the example virtual hosts block to resemble the ones below, replacing
example.comwith your domain.
1 2 3 4 5 6 7 8 9 10 11 12
<VirtualHost *:80> ServerAdmin email@example.com ServerName example.com ServerAlias www.example.com DocumentRoot /srv/http/example.com/public_html/ ErrorLog /srv/http/example.com/logs/error.log CustomLog /srv/http/example.com/logs/access.log combined <Directory /> Order deny,allow Allow from all </Directory> </VirtualHost>
Remove the second example in the file, or use it configure a second website.
CustomLogentries are suggested for more fine-grained logging, but are not required. If they are defined (as shown above), the
logsdirectories must be created before you restart Apache.
Create the directories referenced in the configuration above:
sudo mkdir -p /srv/http/default sudo mkdir -p /srv/http/example.com/public_html sudo mkdir -p /srv/http/example.com/logs
After you’ve set up your virtual hosts, issue the following command to run Apache for the first time:
sudo systemctl start httpd.service
You should now be able to access your website. If no files are uploaded you will see an Index of / page.
Should any additional changes be made to a configuration file restart Apache:
sudo systemctl restart httpd.service
Install and Configure
By default, Arch Linux provides MariaDB as a relational database solution. MariaDB is an open source drop-in replacement for MySQL, and all system commands that reference
mysql are compatible with it.
sudo pacman -Syu mariadb mariadb-clients libmariadbclient
Install the MariaDB data directory:
sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
Start MySQL and set it to run at boot:
sudo systemctl start mysqld.service sudo systemctl enable mysqld.service
mysql_secure_installation, a program that helps secure MySQL.
mysql_secure_installationgives you the option to set your root password, disable root logins from outside localhost, remove anonymous user accounts, remove the test database and then reload the privilege tables:
Create a Database
Log into MySQL:
mysql -u root -p
-u <user>specifies the user, and
-pwill prompt you for the password.
You will see the MariaDB prompt. Create a database and create and grant a user permissions on the database:
CREATE DATABASE webdata; GRANT ALL ON webdata.* TO 'webuser' IDENTIFIED BY 'password';
In this example
webdatais the name of the database,
webuseris the username, and
passwordis the user’s password. Note that database usernames and passwords do not correlate to system user accounts.
With Apache and MySQL installed, you are now ready to move on to installing PHP to provide scripting support for your web application.
PHP makes it possible to produce dynamic and interactive pages using your own scripts and popular web development frameworks. Many popular web applications like WordPress are written in PHP. If you want to develop your websites using PHP, you must first install it.
sudo pacman -Syu php php-apache
/etc/php/php.inifor better error messages and logs, and upgraded performance. These modifications provide a good starting point for a Linode 2GB:
1 2 3 4 5
error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR log_errors = On error_log = /var/log/php/error.log max_input_time = 30 extension=mysql.so
NoteEnsure that all lines noted above are uncommented. A commented line begins with a semicolon (;).
Create the log directory for PHP and give the Apache user ownership:
sudo mkdir /var/log/php sudo chown http /var/log/php
Enable the PHP module in the
/etc/httpd/conf/httpd.conffile by adding the following lines in the appropriate sections:
1 2 3 4 5 6 7 8 9 10 11
# Dynamic Shared Object (DSO) Support LoadModule php7_module modules/libphp7.so AddHandler php7-script php # Supplemental configuration # PHP 7 Include conf/extra/php7_module.conf # Located in the <IfModule mime_module> AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps
In the same file, comment out the line
LoadModule mpm_event_module modules/mod_mpm_event.soby adding a
#in front, and add the line
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so:
#LoadModule mpm_event_module modules/mod_mpm_event.so LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
Restart the Apache:
sudo systemctl restart httpd.service
