Configure WINDOW10 to remotely connect to a database on a virtual machine (Mysql,redis)

The above is a modification to be made on the server

/**
* This time to connect MySQL if still unsuccessful, the server will be reported to reject the connection. Error is
* (Message from server: "Host ' 192.168.11.1 ' isn't allowed to connect to this MySQL server")
* or direct connection is successful.
* This time we're going to open the server's 3306 interface: (note Be sure to turn on the firewall and then open 3306 ports)
* 1, Firewall open 3306 port (sudo ufw allow 3306)
* 2. Turn on Firewall View status: (A, sudo ufw enable B, sudo ufw default deny)
* 3. View firewall status (sudo UFW status)
* OR View port status directly (show global variables like ' port ';)
*

Tips (Tip: You can open the telent of window 10 first

In Control Panel > Programs > (Dropdown page to last) programs and features > turn on and turn off Windows features on the left > turn on telent Service)

Then (win+ R key) can use the telent way to try to spell the server port first.
