[root@centos7-1 nginx-1.12.0]# vim /etc/init.d/nginx

#!/bin/bash

# chkconfig: - 99 20

PROG="/usr/local/nginx/sbin/nginx"               //主程序路径

PIDF="/usr/local/nginx/logs/nginx.pid"           //PID存放路径

case "$1" in

  start)

    $PROG

    ;;

  stop)

    kill -s QUIT $(cat $PIDF)              //根据PID中止nginx进程

    ;;

  restart)

    $0 stop

    $0 start

    ;;

  reload)

    kill -s HUP $(cat $PIDF)              //根据进程号重载配置

    ;;

  *)

        echo "Usage: $0 {start|stop|restart|reload}"

        exit 1

esac

exit 0

[root@centos7-1 nginx-1.12.0]# chmod +x /etc/init.d/nginx
