本文介绍了一个用于启动、停止及重新加载 Nginx 的 shell 脚本。该脚本通过简单的命令实现了对 Nginx 服务的有效管理，并指定了配置文件的位置。适用于需要快速部署和管理 Nginx 服务的场景。

#!/bin/bash
#
# nginx      This shell script takes care of starting and stopping
#            standalone nginx.

# config: /usr/local/nginx/conf/nginx.conf

# Source function library.

. /etc/rc.d/init.d/functions

 RETVAL=0
 prog="nginx"

start() {
      #start nginx
      [ -x /usr/local/nginx/sbin/nginx ] || exit 4
      [ -z /usr/local/nginx/conf/nginx.conf ] && exit 6
      echo -n $"Starting $prog: "
      daemon /usr/local/nginx/sbin/nginx 2>/dev/null
      RETVAL=$?
      echo
      return $RETVAL     
}

stop () {
     #stop nginx
     echo -n $"Shutting down $prog: "
     daemon /usr/local/nginx/sbin/nginx -s stop 2>/dev/null
     RETVAL=$?
     echo
     return $RETVAL
}

reload () {
     #reload  nginx
     echo -n $"Reload the config of $prog: "
     daemon /usr/local/nginx/sbin/nginx -s reload 2>/dev/null
     RETVAL=$?
     echo
     return $RETVAL
}
