MariaDB/MySQL

1
sudo mysql --defaults-file=/etc/mysql/debian.cnf
2

3
create database wpdb;

NGINX

1
sudo apt install nginx-light

At this point I am not ashamed to admit that I’m using VMs on my desktop (VirtualBox). And, for some reason my browser won’t show plain HTTP. That’s why my configuration is HTTPS all the way! I don’t like surprises just for case study, so I made the port as the same as the VirtualBox port forwarding.

The SSL config is snakeoil-ui, a snakeoil snippet changed to use my own valid SSL certs. As I said, no surprise!

1
server {
2
        listen 10443 ssl default_server;
3
        listen [::]:10443 ssl default_server;
4
        include snippets/snakeoil-ui.conf;
5
        root /var/www/html;
6
        index index.html index.htm index.nginx-debian.html index.php;
7

8
        server_name example.org;
9

10
        location / {
11
                try_files $uri $uri/ /index.php$is_args$args;
12
        }
13

14
        location ~ \.php$ {
15
                include snippets/fastcgi-php.conf;
16
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
17
        }
18

19
        location ~ /\.ht {
20
                deny all;
21
        }
22
}

I changed server_name from _ to example.org, a valid FQDN. WP Cassify uses $server_name as its identifier to CAS. It made CAS failed redirected back into our WP site.
