After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

After that, run the commands below to secure MariaDB server.

sudo mysql_secure_installation

    root /var/www/html/processwire;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
        try_files $uri $uri/ /index.php?it=$uri&$args;
