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.
1. This guide is written for a non-root user. Commands that require elevated privileges are prefixed with
2. Update your system:
Apache Install and Configure
Install Apache 2.4:
sudopacman -Syu apache
Edit the httpd-mpm.conf Apache configuration file in
/etc/httpd/conf/extra/to adjust the resource use settings.
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
StartServers 4 MinSpareServers 20 MaxSpareServers 40 MaxRequestWorkers 200 MaxConnectionsPerChild 4500
- Edit the
httpd-default.conffile to turn KeepAlive off.
/etc/httpd/conf/extra/httpd-default.conf 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.conf and edit the line
DocumentRoot /srv/http to define the default document root:
2. Uncomment the line that reads Include
conf/extra/httpd-vhosts.conf near the end of the
3. Open httpd-vhosts.conf, under the extra folder. Edit the example virtual hosts block to resemble the ones below, replacing example.com with your domain.
/etc/httpd/conf/extra/httpd-vhosts.conf <VirtualHost *:80> ServerAdmin firstname.lastname@example.org 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 the second website.
ErrorLog and CustomLog entries are suggested for more fine-grained logging but are not required. If they are defined (as shown above), the logs directories must be created before you restart Apache.
4. 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
5. 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.
MySQL 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.
1. Install the
mariadb, mariadb-clients and libmariadbclient packages:
sudo pacman -Syu mariadb mariadb-clients libmariadbclient
2. Install the MariaDB data directory:
sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
3. Start MySQL and set it to run at boot:
sudo systemctl start mysqld.service sudo systemctl enable mysqld.service
4. Run mysql_secure_installation, a program that helps secure MySQL. mysql_secure_installation gives 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
1. Log into MySQL:
mysql -u root -p
-u specifies the user, and
will prompt you for the password.
2. You will see the MariaDB prompt. Create a database and create and grant a user permissions on the database:
CREATE DATABASE databasename; GRANT ALL ON databasename.* TO 'username' IDENTIFIED BY 'password';
3. To quit MariaDB type:
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.
1. Install PHP:
sudo pacman -Syu php php-apache
2. Edit /etc/php/php.ini for better error messages and logs, and upgraded performance.
/etc/php/php.ini 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
Ensure that all lines noted above are uncommented. A commented line begins with a semicolon (;).
3. Create the log directory for PHP and give the Apache user ownership:
sudo mkdir /var/log/php sudo chown http /var/log/php
4. Enable the PHP module in the /etc/httpd/conf/httpd.conf file by adding the following lines in the appropriate sections:
/etc/httpd/conf/httpd.conf # 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.so by adding a # in front, and add the line LoadModule mpm_prefork_module modules/mod_mpm_prefork.so:
/etc/httpd/conf/httpd.conf #LoadModule mpm_event_module modules/mod_mpm_event.so LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
5. Restart the Apache:
sudo systemctl restart httpd.service
