In this tutorial, we will show you how to install and configure WordPress on Debian 9. For those of you who didn’t know, WordPress is the most popular open-source blogging and CMS platform worldwide, powering a quarter of all websites on the Internet today. It is based on PHP and MySQL and packs a ton of features that can be extended with free and premium plugins and themes. WordPress is the simplest way to create your website or blog.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation of WordPress on a Debian 9 (Stretch) server.
Install WordPress on Debian 9 Stretch
Step 1. Before we install any software, it’s important to make sure your system is up to date by running these following apt-get commands in the terminal:
apt-get update apt-get upgrade
Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.
A Debian 9 LAMP server is required. If you do not have LAMP installed, you can follow our guide here.
Step 3. Installing WordPress.
The first thing to do is to go to WordPress’s download page and download the latest stable version of WordPress, At the moment of writing this article it is version 4.9.8:
Unpack the WordPress archive to the document root directory on your server:
unzip -q latest.zip -d /var/www/html/ cd wordpress cp -a * ..
We will need to change some folder permissions:
chown www-data:www-data -R /var/www/html/
Step 4. Configuring MariaDB for WordPress.
By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set the root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:
Configure it like this:
- Set root password? [Y/n] y - Remove anonymous users? [Y/n] y - Disallow root login remotely? [Y/n] y - Remove test database and access to it? [Y/n] y - Reload privilege tables now? [Y/n] y
Next, we will need to log in to the MariaDB console and create a database for WordPress. Run the following command:
mysql -u root -p
This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server, you need to create a database for WordPress installation:
CREATE DATABASE wordpress character set utf8 collate utf8_bin; GRANT ALL PRIVILEGES on wordpress.* to 'wpuser'@'localhost' identified by 'your_password'; FLUSH PRIVILEGES; exit
Step 5. Configuring WordPress
In this step we will configure the main configuration file of WordPress, where we need to configure its basic parameters so that it can be connected with the database and users:
mv wp-config-sample.php wp-config.php
Now open it using any of your favorite editors, to make any changes in the WordPress configuration file:
Here are the values that we need to update according to our previous database and user’s setup:
// ** MySQL settings - You can get this info from your web host ** // /** The name of the database for WordPress */ define('DB_NAME', 'wordpress'); /** MySQL database username */ define('DB_USER', 'wpuser'); /** MySQL database password */ define('DB_PASSWORD', 'your_password'); /** MySQL hostname */ define('DB_HOST', 'localhost');
Step 6. Accessing WordPress.
WordPress will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com or http://server-ip/ and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
