MYSQL is frequently offline, and the normal solution after refreshing

Recently, a large number of servers frequently experience MYSQL disconnection and refresh failures. This problem occurs on windows hosts, and the solution found based on common official errors is invalid.

Symptom: Can't connect to MySQL server on 'localhost' (10061)

Cause: Microsoft released the TCP/IP update Patch (KB967723) on September 23, September 9. If the server enables automatic updates or the software for Automatic Updates is downloaded and updated, this problem occurs.

Some may ask why the patch on the 9th has not been detected yet?

As we all know, the server does not restart every day. Some servers may restart once a month or a year or a half. Some may restart the server after January 1, September 9, so the patch takes effect (I personally think so ).

Patch uninstall method: log on to the server and go to control panel-add and delete programs-(check "show updates" at the top ")

You can see the updated KB967723 patch in it, and uninstall it just like you want to uninstall common software. The uninstallation will prompt you. If the uninstallation may cause program running errors, it doesn't matter. Select "yes ", continue Uninstall.

After the uninstall is complete, the program server is running normally!

As to what vulnerabilities the patch patches fix and whether there will be server security risks after uninstalling the patch, this is the only way to solve this problem if MYSQL runs normally.
