Solve the inexplicable problem of MySQL violently - restart the service!

The author debugged a msql footstep file, the result is that the query is sometimes correct, sometimes incorrect, inexplicable, and there will be a problem of repeated data, and it is very slow.I had no choice but to restart mysql. After restarting, I found that the speed was not slow, and the data was correct!Inexplicable.It seems that the free community version may be a bit of a hidden danger, so remember, if there is a puzzling sql problem, restart the service and try.

Restart command under linux

 service mysqld restart

Remember
