添加nginx为系统服务(service nginx start/stop/restart)

1、在/etc/init.d/目录下编写脚本，名为nginx

  1 #!/bin/sh 
  2 # 
  3 # nginx - this script starts and stops the nginx daemon 
  4 # 
  5 # chkconfig:   - 85 15 
  6 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ 
  7 #               proxy and IMAP/POP3 proxy server 
  8 # processname: nginx 
  9 # config:      /etc/nginx/nginx.conf 
 10 # config:      /etc/sysconfig/nginx 
 11 # pidfile:     /var/run/nginx.pid 
 12 
 13 # Source function library. 
 14 . /etc/rc.d/init.d/functions 
 15 
 16 # Source networking configuration. 
 17 . /etc/sysconfig/network 
 18 
 19 # Check that networking is up. 
 20 [ "$NETWORKING" = "no" ] && exit 0
