WordPress is a popular, free open-source blogging tool and content management system (CMS) based on PHP and MySQL. WordPress has seen incredible adoption rates and is a great choice for getting a website up and running quickly. After setup, almost all the administration can be done through the web frontend.

In this tutorial, you will learn how to install WordPress on a freshly created Ubuntu Bionic Beaver instance with LEMP (Linux + Nginx - pronounced “engine x” + MySQL + PHP). Nginx is an HTTP server that, compared to Apache, uses fewer resources and delivers pages much faster, especially static files.

Before you start

To complete the actions presented below, you must have:

A Scaleway account logged into the console
Owner status or IAM permissions allowing you to perform actions in the intended Organization
An SSH key
sudo privileges or access to the root user
Installed LEMP
An FQDN (Fully Qualified Domain Name) pointing to your Instance’s IP address
Secured your LEMP stack with TLS/SSL

Installing the stack

As a tutorial on LEMP is already available, you can follow the procedure at Installing LEMP on Ubuntu Bionic Beaver.

WordPress serves dynamic content and handles user authentication and authorization. TLS/SSL is the technology that allows you to encrypt the traffic from your site so that your connection is secure. To secure your connection, ensure that you complete the last stage of the tutorial linked above: Configuring SSL with Let’s Encrypt.

Configuring Nginx to serve WordPress

You need to configure Nginx to deliver traffic to the future WordPress installation. In the LEMP tutorial we created a server block for example.com, serving the default Nginx page from our domain example.com. Here, we will create a server block wordpress which will serve a WordPress site from our subdomain blog.example.com.

Create a new server block for Nginx:

nano /etc/nginx/sites-available/wordpress

Paste the following configuration. Make sure to replace the configuration at the server_name line with your domain.

server {
        listen 80;
        root /var/www/wordpress;
        index index.php index.html index.htm;
        server_name blog.example.com;
        location = /50x.html {
                root /usr/share/nginx/html;
        }
location / {
                # try_files $uri $uri/ =404;
                try_files $uri $uri/ /index.php?q=$uri&$args;
        }
        location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/run/php/php7.2-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
location = /favicon.ico {
        access_log off;
        log_not_found off;
        expires max;
}
location = /robots.txt {
        access_log off;
        log_not_found off;
}
# Cache Static Files For As Long As Possible
location ~*
\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$
{
        access_log off;
        log_not_found off;
        expires max;
}
# Security Settings For Better Privacy Deny Hidden Files
location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
}
# Return 403 Forbidden For readme.(txt|html) or license.(txt|html)
if ($request_uri ~* "^.+(readme|license)\.(txt|html)$") {
    return 403;
}
# Disallow PHP In Upload Folder
location /wp-content/uploads/ {
        location ~ \.php$ {
                deny all;
        }
}
}

Test the configuration to ensure that it will function correctly:

nginx -t

which returns

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Enable the server block by symlinking:

ln -s /etc/nginx/sites-available/wordpress /etc/nginx/sites-enabled/wordpress

Delete the Nginx default server block:

rm /etc/nginx/sites-enabled/default

Steps 6 and 7 optimize your Nginx configuration for WordPress:

Open the Nginx configuration file:

nano /etc/nginx/nginx.conf

Edit the following to optimize:

Tip

Ensure the number of worker processes is equal to the number of cores in your Instance.

user www-data;
worker_processes 1;
pid /run/nginx.pid;

Add use epoll to the events block

events {
worker_connections 4096;
multi_accept on;
use epoll;
}

Add client_max_body_size and server_tokens off directive. Set keepalive_timeout to 30 seconds.

      # Basic Settings
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 30;
types_hash_max_size 2048;
server_tokens off;
client_max_body_size  100m;
      # server_names_hash_bucket_size 64;
      # server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;

Make sure that the whole Gzip settings block is similar to

        # Gzip Settings
gzip on;
gzip_disable "msie6";
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

Restart the server:

service nginx restart

Configuring PHP

If you want to upload files weighing more than 2 MB to your WordPress site, you have to increase PHP upload size variables in php.ini.

Open the php.ini file:

nano /etc/php/7.2/fpm/php.ini

Press Ctrl+W and search for upload_max_filesize and set it to 100M.1. Open the php.ini file:

nano /etc/php/7.2/fpm/php.ini

Press Ctrl+W and search for upload_max_filesize and set it to 100M.

Restart PHP.

sudo service php7.2-fpm restart

Setting up the MySQL database

In this section, we will create the database user and tables.

Log into the MySQL shell using your MySQL root password.

mysql -u root -p

Create a WordPress database, along with a user in the database. First, let’s make the database (feel free to give it whatever name you like):

MariaDB [(none)]> CREATE DATABASE wordpress;

The output displays:

Query OK, 1 row affected (0.00 sec)

Create a new user. Replace the database, name, and password with whatever you prefer:

CREATE USER wordpressuser@localhost;

The output displays:

Query OK, 0 rows affected (0.00 sec)

Set a password for the new user:

SET PASSWORD FOR wordpressuser@localhost= PASSWORD("password");

The output displays:

Query OK, 0 rows affected (0.00 sec)

Grant all privileges to the new user. Without this command, the WordPress installer will not be able to start up:

GRANT ALL PRIVILEGES ON wordpress.* TO wordpressuser@localhost IDENTIFIED BY 'password';

The output displays:

Query OK, 0 rows affected (0.00 sec)

Refresh MySQL:

FLUSH PRIVILEGES;

The output displays:

Query OK, 0 rows affected (0.00 sec)

Exit the MySQL shell:

exit

Installing the WordPress files

Navigate to the site root directory:

cd /var/www/

Download the latest version of WordPress:

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

Extract it from the archive:

tar -xzvf latest.tar.gz

Give the permissions of /var/www/wordpress to www-data user. It will allow future automatic updating of WordPress plugins and file editing with SFTP.

chown -R www-data:www-data wordpress/
usermod -a -G www-data www-data

Completing the installation through the web interface

Now that the server configuration is complete, we can finish up the installation through the web interface.

In your web browser, navigate to your server’s domain name or public IP address:

http://server_domain_or_IP/wordpress/

Select your language.

You are asked to enter your database information. Before doing so, go back to the terminal to complete the next steps.

Open the WordPress configuration file from your terminal:

nano /var/www/wordpress/wp-config-sample.php

Edit the information for your database under MySQL settings, to replace the default values with those you configured while setting it up. In our case, it looks like this:
```
  // ** 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', 'wordpressuser' );
  /** MySQL database password */
  define( 'DB_PASSWORD', 'password' );
  /** MySQL hostname */
  define( 'DB_HOST', 'localhost' );
  /** Database charset to use in creating database tables. */
  define( 'DB_CHARSET', 'utf8' );
  /** The database collate type. Do not change this if in doubt. */
  define( 'DB_COLLATE', '' );
```
Save and exit the file, then return to your web browser.
Enter the database information for WordPress:
Complete the five-minute WordPress installation process.
Log in. Your dashboard displays.
