php - The server cannot be pinged, but msyql can connect directly. What is the reason?

It should not be a server problem. My colleagues’ computers can all be pinged

telnet and ping are not working

    ping can be turned off. Failure to ping does not mean that the server is not online.

    mysql is a tcp protocol, ping is an igmp protocol, and you can set separate passing rules in the firewall, such as disabling igmp
