1. 准备3台虚拟机，关闭iptables、配置yum源、设置selinux为关闭

192.168.179.130
192.168.179.131
192.168.179.132

[root@localhost ~]# systemctl stop firewalld -----关闭防火墙
[root@localhost ~]# setenforce 0 -----关闭selinux
[root@localhost ~]# yum repolist -----yum源
已加载插件：fastestmirror

[root@localhost ~]# yum -y install gcc gcc-c++ pcre-devel zlib-devel -----安装依赖
[root@localhost ~]# tar xzf nginx-1.12.2.tar.gz 
[root@localhost ~]# cd nginx-1.12.2
[root@localhost nginx-1.12.2]# ./configure && make && make install

3. 配置nginx负载均衡，一台作负载均衡器，另外两台做rs

[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf -----修改配置文件

4. 配置nginx负载均衡调度算法为加权轮询

5. 加权轮询的比例为1：3

6. 给后端两台rs编写不同的测试访问页面

192.168.179.131

[root@localhost log]# cat /usr/local/nginx/html/index.html
web1

192.168.179.132

[root@localhost log]# cat /usr/local/nginx/html/index.html
web2

7. 启动nginx

[root@localhost ~]# /usr/local/nginx/sbin/nginx -----启动nginx

8. 测试nginx访问
