想让配置修改过的mysql能在机器关机或重启时能先停止mysql进程，防止数据异常
在/etc/init.d/下添加脚本，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 执行 chkconfig test_shutdown on
