How to Install WordPress on Ubuntu 18.04 LTE – LEMP Stack

This guide covers the step-by-step guide on how to Install WordPress on Ubuntu 18.04, 16.04, 14.04 LTE Server with LEMP Stack to help your website perform better and faster.

WordPress is a popular, Dynamic and blog-focused content management system. WordPress is by far the most famous and most used content management system for websites. There are 74,652,825 websites are using WordPress as a Content Management System for their websites and it is increasing day by day.

Many of the bloggers and webmasters like me are moving to SSD Cloud hosting for faster and better performance of their websites. So I decided to bring this tutorial, that would help you to install WordPress on SSD cloud, Ubuntu Server. Before you proceed, I would highly recommend to read and implement the Getting started guide and then secure your server. Once you complete both these steps then you can move to this WordPress Installation guide.

Steps to Install WordPress on Ubuntu

Before you begin to make sure you have two things configured:

1. Hostname

Check your hostname by typing the following command:

hostname
hostname –f

The first command will output your hostname, while the second command will output the fully qualified domain name (FQDN).

2. MySQL Database

Once you ensure that these two things are configured on your server, proceed to the next step and install MySQL Server by running the following command:

sudo apt-get install mysql-server

During the installation process, you will be prompted to set a root password. It is recommended that you choose a strong password.

Now harden the MySQL Server by running the mysql_secure_installation script.

sudo mysql_secure_installation

Now, login into your MySQL as a root user using the following command:

mysql -u root -p

Now enter the root login credentials to login into MySQL.

Once you enter into MySQL, create a database for your WordPress based website using the following command:

create database database-name;

Now, grant user privileges for the newly-created database. Replace user and password with the username and password you wish to use:

grant all on database-name.* to 'user' identified by 'password';

Now exit the MySQL:

quit

3. Deploy PHP with FastCGI

We all know that WordPress is PHP based and in order to deploy PHP applications, we need to implement the “PHP-FastCGI”. This will allow NGINX to properly handle and serve PHP based web applications and websites.

For PHP5-FPM

apt-get install php5-cli php5-cgi php5-fpm

For PHP7.0-FPM

sudo apt-get install php7.0-cli php7.0-cgi php7.0-fpm

Once you are done deploying PHP5-FPM or PHP7.0-FPM, you need to move further and install the NGINX web server.

4. NGINX Server Setup

Install NGINX by typing:

sudo apt-get install nginx

Now create a new config file for your websites:

sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/example.com

Now you need to open the config file, in our case, it is example.com, and edit it.

sudo vim /etc/nginx/sites-available/example.com

Now you need to configure this file, and your file should look like this:

server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/website1.com/public_html;
index index.php;
# Make site accessible from http://localhost/
server_name example.com www.example.com *.example.com;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ /index.php;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}

location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
# # With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}

You can keep the exact copy of the above content as well. But do not forget to update the Website Directory and Server Name (server_name).

Once you’ve created and configured the file you can move on.

Next, we need to link this config file to the sites-enabled directory. For that you need to run the following command:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Now, remove the default config file from the sites-enabled directory by typing:

sudo rm /etc/nginx/sites-enabled/default

Finally, restart the NGINX service

sudo service nginx restart

5. Changes Inside HOST file

Open the host file inside the etc directory and update your domain name inside the host file. It should look like something this:

6. Install WordPress

Create an src directory under your website’s directory and download the latest copy of WordPress. In this guide, I have chosen /var/www/exmaple.com/ as a home directory. So, create that directory if you do not have:

sudo mkdir /var/www/example.com/src/

Now, navigate inside the src directory.

cd /var/www/example.com/src/

Now set the owner of the new directory to be your web server’s user. In this instance, our web server is NGINX:

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

Now you need to download the latest version of WordPress and expand it:

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

sudo -u www-data tar -xvf latest.tar.gz

Now you need to move latest.tar.gz by renaming it as WordPress, followed by the date to store a pristine backup of the source files:

sudo mv latest.tar.gz wordpress-`date "+%Y-%m-%d"`.tar.gz

Copy the WordPress files to your public_html folder, then remove the empty WordPress folder in the src directory:

sudo cp -R wordpress
define('FS_METHOD', 'direct');

Once you are done, give WordPress permission to add and edit files in the public_html folder:

sudo chown -R www-data:www-data /var/www/example.com/public_html

Congratulations! Now, you have a successfully installed WordPress based website running.

Now you will be able to login into your new WordPress based website. Next, you can configure your website using a web-based interface.
