Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up-to-date.

sudo yum update -y

mysql --version

Start and enable MariaDB.

sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Run the mysql_secure_installation script to improve the security of your MariaDB installation.

sudo mysql_secure_installation

Log in to MariaDB as the root user.

    server_name stats.example.com;
    root /var/www/matomo;

    location / {
        try_files $uri /index.php$is_args$args;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

}

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo systemctl reload nginx.service

Install Matomo

Create a document root directory.

sudo mkdir -p /var/www/matomo

Change ownership of the /var/www/matomo directory to johndoe.
