220.127.116.11 SHUTDOWN Statement
This statement stops the MySQL server. It requires the
Com_shutdown status variable tracks the number of
SHUTDOWN statements. Because status variables are initialized for each server startup and do not persist across restarts,
Com_shutdown normally has a value of zero, but can be nonzero if
SHUTDOWN statements were executed but failed.
Another way to stop the server is to send it a
SIGTERM signal, which can be done by
root or the account that owns the server process.
SIGTERM enables server shutdown to be performed without having to connect to the server. See Section 4.10, “Unix Signal Handling in MySQL”.
