自动部署Nginx和nfs并架设Nginx集群脚本

本人经过多次尝试,简单完成了自动部署Nginx和nfs脚本,并且能够自动部署web反向代理集群,下面详细的阐述一下本人的思路。(以下脚本本人处于初学阶段,写的并不是很完善,所以需要后期进行整理和修正,请高手能够多多指教。)

本脚本需要注意的是:

1、这是针对centOS6.8,32位操作系统写的脚本文件,如果想在cenOS7中运行,就需要有些改动

2、这个脚本需要先安装代理服务器部分,再安装反向代理服务器,因为涉及到共享文件夹挂载的问题,所以需要有先后顺序;

3、今后本人会对此脚本进行更新和完善,希望朋友们来相互交流。

 

#!/bin/bash 
login=0
server_leader='192.168.1.104'               #设置代理服务器IP地址;
server_web1='192.168.1.105:80 weight=3'     #设置第一台反向代理服务器地址并设置权重参数;
server_web2='192.168.1.106:80'              #设置第二台反向代理服务器地址;
server_web3='192.168.1.107:80'              #设置第三台反向代理服务器地址;
server_nfs='192.168.1.0'                    #设置nfs共享配置文件的网络地址;

function install_nginx(){                                                                         #命名安装nginx的函数;

    yum -y install nginx ;                                                                        #安装Nginx服务;
