How to Install WordPress on Ubuntu 20.04

Prerequisites:

Creating the new database.

Log into MySQL with the following command.

mysql

First, we'll create a new database.

MariaDB [(none)]> CREATE DATABASE wordpress_db;

Next, create a new MySQL user account that we will use to operate on WordPress's new database, with username "wordpress_user".

MariaDB [(none)]> CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'password';

Link the user and DB together by granting our user access to the database.

MariaDB [(none)]> GRANT ALL PRIVILEGES ON wordpress_db.* to wordpress_user@'localhost';

Flush the privileges so that MySQL knows about the user permissions we just added.

MariaDB [(none)]> FLUSH PRIVILEGES;

Exit out of the MySQL command prompt by typing.

MariaDB [(none)]> exit

Output:

root@vps:~# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 55
Server version: 10.3.22-MariaDB-1ubuntu1 Ubuntu 20.04

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Query OK, 0 rows affected (0.002 sec)

MariaDB [(none)]> exit
Bye

Download and install WordPress

Download Wordpress.

 wget -O /tmp/wordpress.tar.gz https://wordpress.org/latest.tar.gz

Unzip the downloaded WordPress file.

tar -xzvf /tmp/wordpress.tar.gz -C /var/www/

Change the permission of the site directory.

chown -R www-data.www-data /var/www/wordpress

Configure Nginx

Configure Nginx VirtualHost file /etc/nginx/conf.d/default.conf.

nano /etc/nginx/conf.d/default.conf

Copy the below content and save into the file.

server {
    listen 80;
    listen [::]:80;
    root /var/www/wordpress;
    index  index.php index.html index.htm;

    client_max_body_size 100M;
    autoindex off;
    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
         include snippets/fastcgi-php.conf;
         fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
    }
}   

Next, test to make sure that there are no syntax errors in any of your Nginx files.

nginx -t

If there aren’t any problems, restart Nginx to enable your changes.

systemctl reload nginx
