想讓配置修改過的mysql能在機器關機或重啓時能先停止mysql進程，防止數據異常
在/etc/init.d/下添加腳本，如下：
#!/bin/sh
### BEGIN INIT INFO
# Provides: test_shutdown
# Required-Start: $syslog
# Should-Start: $time
# Required-Stop: $syslog
# Should-Stop: $time
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: test_shutdown
# Description: test_shutdown
### END INIT INFO
case "$1" in
start)
echo "start" >>/tmp/test.log
sleep 1;;
stop)
echo "begin stop" >>/tmp/test.log
su - test -c "/home/test/scripts/shutdown.sh"
echo "done stop" >>/tmp/test.log
;;
*)
echo "other" >>/tmp/test.log
esac
執行 chkconfig test_shutdown on
