姑且称之为a.sh 在 /home/nginx 目录下
daemon
通过放入hook文件， 在对应的目录下touch start \ stop \restart 文件 ， 实现应用的启停
#!/bin/sh
number=`ps -ef | grep "/home/nginx/daemon/nginx_daemon" | grep -v grep | head -n 1 | wc -l`
if [ $number -lt 1 ];then
#do something
fi
while [ 1 -eq 1 ]
do
if [ -f "/home/nginx/daemon/start" ]; then
rm -rf /home/nginx/daemon/start
/home/nginx/a.sh start
fi
if [ -f "/home/nginx/daemon/stop" ]; then
rm -rf /home/nginx/daemon/stop
/home/nginx/a.sh stop
fi
if [ -f "/home/nginx/daemon/restart" ]; then
rm -rf /home/nginx/daemon/restart
/home/nginx/a.sh restart
fi
sleep 5
done
