Complete guide to installing wordpress 5 on Ubuntu 16.04 server.

Introduction

A complete guide to installing wordpress on your Ubuntu 16.04 server via command line. Includes installing the LAMP stack - Linux, Apache, MySql, and PHP needed to install wordpress.

Requirements

Ubuntu 16.04 server installed and configured with sudo (administrator privileges).

It's as easy as copying and pasting each of the commands.

Step 1 - Install Apache2

Update the Ubuntu package manager

sudo apt-get update

• Enter your sudo (admin password) when prompted.

Install Apache

sudo apt-get install apache2

• Enter 'Y' to agree to disk space requirements.
• You can ignore the warning about Global name server.

Test that apache is up and running by entering your server's IP address in a browser and you should see the Ubuntu Apache2 Default page

Step 2 - Install MySQL

Install MySQL version 5.7

sudo apt-get install mysql-server

• Enter Y to agree to disk space requirements.
• Choose a password for MySQL. Make it strong and unique.
• Re-enter password to confirm.

Secure MySQL

mysql_secure_installation

Enter MySQL root user password (from the step above)

Answer questions about securing MySQL settings

1. Configuring validate password plugin - no (answering yes can create errors down the road)
2. Change the password for root? no (but it's up to you)
3. Remove anonymous users? yes
4. Disable remote login? yes
5. Remove test database? yes
6. Reload privilege tables now? yes

Step 3 - Install PHP

Install PHP 7.0

sudo apt-get install php7.0 libapache2-mod-php7.0 php7.0-mysql php7.0-curl php7.0-mbstring php7.0-gd php7.0-xml php7.0-xmlrpc php7.0-intl php7.0-soap php7.0-zip 

• Enter Y to agree to disk space requirements.

we can test that PHP is installed correctly by replacing the index.html file with an index.php file

Navigate to the HTML directory

cd /var/www/html/

Create and edit a new php file

sudo nano index.php

Copy and paste this php script into the open editor.

<?php phpinfo(); ?>

• Press Ctrl-o to save your changes.
• Press Enter
• Press Ctrl-x to exit the editor.

Delete the index.html file.

sudo rm index.html

Restart Apache to be sure your changes have taken effect.

sudo systemctl restart apache2

Now when you enter your server's IP adress in your browser you should see The PHP page with the version (7.0) that your server is running.

Step 4 - Now you're ready to install wordpress

You should still be in the HTML directory /var/www/html/

We will download The latest version of WordPress

sudo wget -c http://wordpress.org/latest.tar.gz

Extract file into /wordpress/ directory (it creates the wordpress directory when it extracts the file)

sudo tar -xzvf latest.tar.gz

Set permissions for the wordpress directory you just created.

sudo chown -R www-data:www-data /var/www/html/wordpress

Step 6 - Create a database in MySQL for WordPress

Login to MySQL

mysql -u root -p

• Enter the MySQL root password created in step 3 above.

Create a new MySQL database for WordPress installation.

• wordpress_db is the name of your database (can be anything).

CREATE DATABASE wordpress_db;

• wordpress_user is a new user_name (your choice) and PASSWORD is the password for the user (make it strong and unique).

GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost' IDENTIFIED BY 'PASSWORD';

Enable the changes to the new user.

FLUSH PRIVILEGES;

Exit MySQL

exit;

Move into the wordpress directory /var/www/html/wordpress

cd wordpress

Rename the the sample configuration file.

sudo mv wp-config-sample.php wp-config.php

Open and edit the wp-config file.

sudo nano wp-config.php

Update the file with your database information from the beggining of this step (step 6)

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress_db');

/** MySQL database username */
define('DB_USER', 'wordpress_user');

/** MySQL database password */
define('DB_PASSWORD', 'PASSWORD');

• Press Ctrl-o to save your changes.
• Press Enter
• Press Ctrl-x to exit the editor. Restart Apache and MySQL

systemctl restart apache2

• Enter your sudo (admin) password

systemctl restart mysql

• Enter your sudo (admin) password

You're all done. You can go to your server's IP address in a browser of your choice and follow the on screen instructions to finish the installation.
