步骤：

1 [root@localhost ~]# vim /usr/local/nginx-1.12.0/conf/nginx.conf[root@localhost ~]# cp /usr/local/nginx-1.12.0/conf/nginx.conf /usr/local/nginx-1.12.0/conf/nginx1.conf[root@localhost ~]# vim /usr/local/nginx-1.12.0/conf/nginx1.conf[root@localhost ~]# vim /usr/local/nginx-1.12.0/html/index.html[root@localhost ~]# cd /usr/local/nginx-1.12.0/sbin/[root@localhost sbin]# /usr/local/nginx-1.12.0/sbin/nginx -c /usr/local/nginx-1.12.0/conf/nginx.conf[root@localhost sbin]# /usr/local/nginx-1.12.0/sbin/nginx -c /usr/local/nginx-1.12.0/conf/nginx1.conf

修改nginx.conf

    upstream songwei{        server 192.168.16.39:8080;        server 192.168.16.110:8080;#在http和server之间加入这个模块        server 192.168.16.121:8080;    }##后面的serever也得改

nginx.conf的server

    server {        listen       80;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {           proxy_pass http://songwei;           # root   html;           #index  index.html index.htm;        }

修改nginx1.conf（第一个从机）因为我主机作为代理服务器和从机1，所以这样设置

    server {        listen       8080;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {           root   html;           index  index.html index.htm;        }

修改nginx.conf（第二个从机）

  server {        listen       8080;#只修改这里        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {            root   html;            index  index.html index.htm;        }

同理修改第三个从机的nginx.conf

修改index.html

然后重启就ok
