WordPress is a free and open source content management system (CMS) created by Matt Mullenweg and first released in 2003. WordPress has a vast and vibrant community that provides tens of thousands of free plugins and themes to allow the user to easily customize the appearance and function of their WordPress CMS. WordPress is licensed under the GPLv2.
The biggest feature of WordPress is its ease in configuration and administration. Setting up a WordPress site takes five minutes. The WordPress administration panel allows users to easily configure almost every aspect of their website including fetching and installing plugins and themes. WordPress provides effortless automatic updates.

WordPress requires PHP and MySQL to be installed and configured. See the LAMP wiki article for more information. During configuration, be aware that some WordPress features require PHP extensions that may not be turned on by default.
Installation using pacman
Install the package.
Go to wordpress.org and download the latest version of WordPress and extract it to your webserver directory. Give the directory enough permissions to allow your FTP user to write to the directory (used by WordPress).
cd /srv/http/whatever wget https://wordpress.org/latest.tar.gz tar xvzf latest.tar.gz
The configuration method used here assumes you are using WordPress on a local network.
Make sure your
/etc/hosts file is setup correctly. This will be important when accessing your WordPress CMS from a local network. Your
/etc/hosts file should look something like the following,
#<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 lithium.kaboodle.net localhost lithium ::1 lithium.kaboodle.net localhost lithium
You will need to create a config file for apache to find your WordPress install. Create the following file and edit it your favorite text editor:
Alias /wordpress "/usr/share/webapps/wordpress" <Directory "/usr/share/webapps/wordpress"> AllowOverride All Options FollowSymlinks Require all granted </Directory>
/wordpress in the first line to whatever you want. For example,
/myblog would require that you navigate to
http://hostname/myblog to see your WordPress website.
Also change the paths to your WordPress install folder in case you did a manual install. Do not forget to append the parent directory to the
php_admin_value variable as well as shown below.
Alias /myblog "/mnt/data/srv/wordpress" <Directory "/mnt/data/srv/wordpress"> AllowOverride All Options FollowSymlinks Require all granted </Directory>
Next edit the Apache configuration file and add the following:
httpd.service (Apache) using systemd.
MySQL can be configured using a plethora of tools, but the most common are the command-line or phpMyAdmin.
Using MariaDB command-line tool
First, login as root. You will be asked for your MariaDB root password:
$ mysql -u root -p
Then create a user and database:
wordpressis your Database Name and
wp-useris your User Name. You can change them if you wish. Also replace
choose_db_passwordwith your new Password for this database. You will be asked for these values along with
localhostin the next section.
MariaDB> CREATE DATABASE wordpress; MariaDB> GRANT ALL PRIVILEGES ON wordpress.* TO "wp-user"@"localhost" IDENTIFIED BY "choose_db_password"; MariaDB> FLUSH PRIVILEGES; MariaDB> EXIT
See WordPress.org official instructions for details.
See phpMyAdmin to install and configure phpMyAdmin.
In your web browser, navigate to your phpMyAdmin host and perform the following steps:
- Login to phpMyAdmin.
- Click "user" and then click "Add user".
- Give the pop up window a name and a password.
- Select "Create database with same name and grant all privileges".
- Click the "Add user" button to create the user.
Once you have spent a couple of hours setting up your http server, php, and mysql, it is finally time to let WordPress have its five minutes and install itself. So let us begin.
The WordPress installation procedure will use the URL in the address field of your web browser as the default website URL. If you have navigated to http://localhost/wordpress, your website will be accessible from your local network, but it will be broken in appearance and function.
- Navigate to
- Click the "Create a Configuration File" button.
- Click the "Let's go!" button.
- Fill in you database information created in the previous section
- Click "Submit".
If you installed WordPress from the Official repository, then this setup procedure will not have the correct permissions to create the wp-config.php file used by WordPress. You will have to do this step yourself as root using information WordPress will provide.
A page will appear saying WordPress can not write the wp-config.php file. Copy the text in the edit box and open
/usr/share/webapps/wordpress/wp-config.php as root in your text editor. Paste the copied text into the editor and save the file.
After that, you will have to change permissions of the /usr/share/webapps/wordpress/ and all the files inside it to user
http and group
http by using chown so that the webserver can access it.
Finally, Click "Run the install" and WordPress will populate the database with your information. Once complete, you will be shown "Success!" page. Click the login button to finish your installation.
Now would be a good time to access your website from all your devices to be sure your WordPress installation is setup correctly.
Installing a theme
Finding new themes
There are tens of thousands of themes available for WordPress. Searching on google for a good theme can be like wading through a river filled with trash. Good places for looking for themes include:
Install using the admin panel
Before installing a theme using the admin panel, you will need to setup an FTP server on your WordPress host. To maintain a high level of protection, you might set up a user on your system specifically for WordPress, give it the home directory of
<path to your WordPress install>/wp-content, disallow anonymous login, and allow no more users to log in than for WordPress (and obviously others as required by your setup).
Once the FTP server is setup, login to your WordPress installation and click "Appearance->Install Themes->Upload". From there select your zip file that contains your theme and click "Install Now". You will be presented with a box asking for FTP information, enter it and click "Proceed". You might need to update file ownership and rights if WordPress reports that it is unable to write to the directory. If you have been following along closely, you should now have an installed theme. Activate it if you wish.
Download the archive and extract into the wp-content/themes folder
# Example for a theme named "MyTheme" cd /path/to/wordpress/root/directory cd wp-content/themes
# get the theme archive and extract wget http://www.example.com/MyTheme.zip unzip MyTheme.zip
# remove the archive (optional) rm MyTheme.zip
Be sure to follow any additional instructions as provided by the theme author.
Select your new theme from the theme chooser ("Appearance->Themes")
Installing a plugin
The steps for installing a plugin are the same as they are for installing a theme. Just click the "Plugins" link in the left navigation bar and follow the steps.
Every now and then when you log into wordpress there will be a notification informing you of updates. If you have correctly installed and configured an FTP client, and have the correct filesystem permissions to write in the WordPress install path then you should be able to perform updates at the click of a button. Just follow the steps.
Alternatively, you can use SSH to update your installation with the SSH SFTP Updater Support plugin.
Appearance is broken (no styling)
Your WordPress website will appear to have no styling to it when viewing it in a web browser (desktop or mobile) that does not have its hostnames mapped to ip addresses correctly.
This occurs because you used a url with the hostname of your server, instead of an ip address, when doing the initial setup and WordPress has used this as the default website URL.
To fix this, you will either need to edit your /etc/hosts file or setup a proxy server. For an easy to setup proxy server, see Polipo, or if you want something with a little more configuration, see Squid.
Another option is changing a value in the database table of your WordPress, specifically the wp_options table. The fix is to change the siteurl option to point directly to the domain name and not "localhost".
