SHUTDOWN
This statement stops the MySQL server. It requires the
SHUTDOWN privilege.
SHUTDOWN provides an SQL-level
interface to the same functionality available using the
mysqladmin shutdown command or the
mysql_shutdown() C API function.
A successful SHUTDOWN sequence
consists of checking the privileges, validating the arguments,
and sending an OK packet to the client. Then the server is shut
down.
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 6.10, “Unix Signal Handling in MySQL”.
