  1. Open SSH session to your Ubuntu 18.04 server using root or any ‘sudo’ enabled user.
  2. A domain/subdomain pointing to the WordPress installation.
  3. Domain/subdomain DNS A-record locating to server’s IP address. (To get the IP, Check the control panel of Ubuntu server).

Note: In this tutorial, we are using abc.com as domain name for an instance. In your case, do make sure to replace the abc.com with your own domain name, where you see.

Step 1: Update Ubuntu 18.04

Before you start to install Nginx/Lemp, it’s suggested to update your server with latest updates. Here are the commands to do that.

sudo apt-get update 
sudo apt-get upgrade

Step 2: Install WordPress with Nginx on Ubuntu 18.04

Once the server packages are up-to-date, you can follow further steps to install WordPress with Nginx using MySQL, and PHP.

Step 2.1: Install Nginx

In Ubuntu, Nginx is available in default repositories and can be installed easily with the the command below.

sudo apt-get install nginx

After the Nginx is installed, it’s suggested to stop, start and enable Nginx service to assure its initialization after ever server boots. Below are the commands to run

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Step 2.2: Install MySQL

Since wordpress needs a Database to work with, we suggest to use MySQL. To install it, run the commands.

sudo apt-get install mysql-server

While the installation is done, you will be asked to input your password for MySQL. Do make sure to input a strong password. And hit enter to re-enter the password again.

With above executed commands, MySQL is installed with default settings, but you need to make it more secure with further commands below.

sudo mysql_secure_installation

After running above command, you will be asked to answer various questions to assure your security. We suggest you to do as mentioned below.

  • Feed the current password for root (Press enter for none), Press Enter key.
  • Set Root password? [Y/m]: Y
  • New Password: Enter your password here
  • Re-enter new password: Repeat your password once again
  • 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

Once done, restart MySQL server’s

sudo systemctl restart mysql.service

Step 2.3: Install PHP 7.1 and Essential WordPress Modules

WordPress CMS requires PHP. In order to install PHP 7.1 it’s required to add a third party repository. To do so, run the commands below to add the repository and upgrade to PHP 7.1

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

The above command will add repository to Ubuntu server, next is to upgrade to PHP 7.1

sudo apt update

Now, run the commands mentioned to install PHP 7.1 FPM and other related modules.

sudo apt install php7.1-fpm php7.1-common php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-gd php7.1-xml php7.1-intl php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-zip php7.1-curl

Now, run the commands below to open PHP-FPM default file.

sudo nano /etc/php/7.1/fpm/php.ini

In the default file, do some modifications in the following lines and save the file. We suggest you to fee below settings to make WordPress easily in server.

file_uploads = On
allow_url_fopen = On
memory_limit = 256M
upload_max_filesize = 100M
cgi.fix_pathinfo=
max_execution_time = 360
date.timezone = America/Chicago

Step 2.4: Create Database for WordPress

In order to create database for wordpress, you first need to login to MySQL, below is the command to run. When asked, enter your root password.

sudo mysql -u root -p

Now, create a databse with below command. We have created a database named “servonode” in the example below.

CREATE DATABASE servonode;

Create a database user for the database with name “servonodeuser” with a new password

CREATE USER 'servonodeuser'@'localhost' IDENTIFIED BY 'new_password_here';

Next is to grant full access to created user over created database.

GRANT ALL ON servonode.* TO 'servonodeuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Lastly, save the changes and quit MySQL.

FLUSH PRIVILEGES;
EXIT;

Step 2.5: Download WordPress Latest Release and Save The Files Under A Directory

In order to download WordPress latest release, visit the WordPress site and download the latest version. Then extract the downloaded file and move it into a new WordPress root directory (servonode is taken here as example).

cd /tmp && wget https://wordpress.org/latest.tar.gz
tar -zxvf latest.tar.gz
sudo mv wordpress /var/www/servonode

Set correct permissions to assigned root directory for wordpress to work properly.

sudo chown -R www-data:www-data /var/www/servonode/
sudo chmod -R 755 /var/www/servonode/

Step 2.6: Nginx HTTP Server Configuration

You need now to configure Nginx site configuration file for WordPress. This file is essential to control how users can access your wordpress content, just run the commands below to create a new WordPress configuration file called “servonode.conf”

sudo nano /etc/nginx/sites-available/servonode.conf

Just copy the code content below and paste it into the configuration file and save it. Do not forget to replace the highlighted value with your own domain and directory root location.

server {
listen 80;
listen [::]:80;
root /var/www/servonode;
index index.php index.html index.htm;
server_name example.com www.example.com;

client_max_body_size 100M;

location / {
try_files $uri $uri/ /index.php?$args; 
}

location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}

Save the modified file and exit.

Step 2.8: Restart Nginx Service

Once the configuration file is configured and enabled, it’s suggested to restart Nginx with the commands below.

sudo systemctl restart nginx.service

or 

sudo service nginx restart

Step 2.9: Configure Wp-config.php

Here’s the command to rename wp-config-sample.php to wp-config.php and feed the data we have created above to configure WordPress configuration file.

sudo mv /var/www/servonode/wp-config-sample.php /var/www/servonode/wp-config.php

Now, execute the following command to open and edit WordPress configuration file.

sudo nano /var/www/servonode/wp-config.php

Once the file is opened, feed the data like database name, database user name, and password as highlighted in the section below.

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

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

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

/** MySQL hostname */
define('DB_HOST', 'localhost');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');
