2 标红位置修改为自己的文件路径

  nginx="/usr/local/nginx/sbin/nginx" 修改成nginx执行程序的路径。

  NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" 修改成配置文件的路径。

3 保存脚本文件后设置文件的执行权限:

  chmod a+x /etc/init.d/nginx

通过该脚本启动停止nginx服务

  /etc/init.d/nginx start

  /etc/init.d/nginx stop

使用chkconfig进行管理,将nginx服务加入chkconfig管理列表

  chkconfig --add /etc/init.d/nginx

6 使用service对nginx进行启动,停止。重启等操作

  service nginx start
  service nginx stop

7 设置终端模式开机启动

  chkconfig nginx on

8 如果出现/bin/sh^M:损坏的解释器: 没有那个文件或目录 错误

  原因是这个脚本是在windows环境下编写的,所以换行符不一致导致错误发生,换行结尾符是\n\r,但是在linux下是\n,所以在每个换行的地方会多出来个\r
