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
