mysql 8 comes with mysqlx plugin listening on all interfaces by default

[zeisss]

Not sure if this something you want to fix in the your defaults, but this was quite surprising to us:

Mysql 8 comes with a plugin called "mysql x" that openes a second server socket (port * 10 by default) on all interfaces (in our case: the public internet).

Given that this role sets the bind-address by default to localhost, it might also wants to set the mysqlx-bind-address to something more restrictive and/or disable it default.

I second that. I wish there was a way to disable the mysqlx with ansible variable to add to config file
mysqlx=0 as this is certainly a security risk:

ss -tulpn
Netid     State      Recv-Q     Send-Q         Local Address:Port           Peer Address:Port     Process     
...
tcp       LISTEN     0          151                127.0.0.1:3306                0.0.0.0:*                    
tcp       LISTEN     0          70                         *:33060                     *:*

This should definitely get fixed, please reopen! @geerlingguy

Ubuntu/Debian defaults to localhost

> grep bind /etc/mysql/mysql.conf.d/mysqld.cnf 
bind-address		= 127.0.0.1
mysqlx-bind-address	= 127.0.0.1

This role should really default to 127.0.0.1 on both bind addresses instead of 0.0.0.0.
