Install Wordpress on a Linux virtual machine
WordPress is the most popular CMS (content management system) on the internet. It allows you to easily set up flexible blogs and websites on top of a MySQL backend with PHP processing. WordPress has seen incredible adoption and is a great choice for getting a website up and running quickly. After setup, almost all administration can be done through the web frontend.

You will need to perform the following tasks before you can start this guide:
- Create a new Ubuntu or Centos server
- Install a LEMP or LAMP stack: WordPress will need a web server, a database, and PHP in order to correctly function.
- Setting up a LEMP or LAMP stack (Linux, Apache, MySQL, and PHP) fulfills all of requirements.
To install and configure software for LEMP stack follow the tutorial Install a LEMP web server on a Linux virtual machine and or if you want to use LAMP stack follow the tutorial Install a LAMP web server on a Linux virtual machine
When you are finished the setup steps, log into your server as your sudo user and continue below.
Install WordPress on an Ubuntu VM
1) To install the WordPress package run the following command:
sudo apt install wordpress
2)After that you need to configure WordPress by using MySQL and PHP.
2.1) In a working directory, create a text file
wordpress.sql to configure the MySQL database for WordPress:
sudo sensible-editor wordpress.sql
2.2) Add the following commands, substituting a database password of your choice for yourPassword (leave other values unchanged). If you previously set up a MySQL security policy to validate password strength, make sure the password meets the strength requirements. Save the file.
CREATE DATABASE wordpress; GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,ALTER ON wordpress.* TO wordpress@localhost IDENTIFIED BY 'yourPassword';
2.3) Run the following command to create the database:
cat wordpress.sql | sudo mysql --defaults-extra-file=/etc/mysql/debian.cnf
2.4) Because the file
wordpress.sql contains database credentials, delete it after use:
sudo rm wordpress.sql
2.5) To configure PHP, run the following command to open a text editor of your choice and create the file
sudo sensible-editor /etc/wordpress/config-localhost.php
Copy the following lines to the file, substituting your WordPress database password for yourPassword (leave other values unchanged). Then save the file.
<?php define('DB_NAME', 'wordpress'); define('DB_USER', 'wordpress'); define('DB_PASSWORD', 'yourPassword'); define('DB_HOST', 'localhost'); define('WP_CONTENT_DIR', '/usr/share/wordpress/wp-content'); ?>
2.6) Move the WordPress installation to the web server document root:
sudo ln -s /usr/share/wordpress /var/www/html/wordpress sudo mv /etc/wordpress/config-localhost.php /etc/wordpress/config-default.php
2.7) Now you can complete the WordPress setup and publish on the platform. Open a browser and type in your IP address/wordpress. Substitute the public IP address of your VM. It should look similar to this image.
Install WordPress on a Centos VM
1) Login to your mysql server using the command:
mysql -u root -p
2) Then create a database by following the commands. For this tutorial we will create a database named “orders_newdatabasename” with a user “orders_dbuser” and password of “mynewpassword”.
You will have to write down this information since we will use it later on.
CREATE DATABASE wordpress_sample; CREATE USER wp_user@localhost IDENTIFIED BY 'wp_password'; GRANT ALL PRIVILEGES ON wordpress_sample.* TO wp_user@localhost; FLUSH PRIVILEGES; exit
3) Let us install php-gd first, this module is used to resize images so we can create a thumbnail. Let us try to fetch the package from CentOS repository:
sudo yum install php-gd
4) After that we will need to restart our httpd server so it can recognize the newly installed module:
sudo service httpd restart
6) Let us install Wget programm:
sudo yum install wget
5) Go to your /html folder before we download the latest wordpress files. The /html folder is the public facing folder of your webserver.
6) Download the last version of wordpress files:
7) Let us install unzip programm:
sudo yum install unzip
8) Unzip the wordpress files in the /var/www/html directory:
9) We need to restart httpd web server one more time for it to work by typing:
systemctl restart httpd
10) And then we set the appropriate permissions for the html directory and files to increase wordpress security and to avoid problems with permissions later on as we configure our wordpress.
sudo chown -R apache:apache /var/www/html/*
11) Now you can complete the WordPress setup and publish on the platform. Open a browser and type in your IP address/wordpress. Substitute the public IP address of your VM. It should look similar to this image.
