环境：根据https://blog.csdn.net/qq_27384769/article/details/81232447配置

方法一：根据目录实现动静分离

在web01创建image并上传一张图片作为静态页面

[root@web01 /]# cd /var/www/www/
[root@web01 www]# pwd
/var/www/www
[root@web01 www]# mkdir image
[root@web01 www]# ls
image  index.html
[root@web01 www]# cd image/
[root@web01 image]# yum -y install lrzsz  #用于文件上传工具
[root@web01 image]# ls
nginx.jpg       #上传一张图片

测试web01请求页面是否能正常访问

在web02创建一个dynamic测试页作为动态请求页面

把web01上的image的内容同步到web02上

[root@web02 /]# cd /var/www/www/
[root@web02 www]# pwd
/var/www/www
[root@web02 www]# mkdir dynamic
[root@web02 www]# ls
dynamic  index.html
[root@web02 www]# echo dynamic > dynamic/index.html

测试

修改LB的配置文件  /usr/local/nginx/conf/nginx.conf

upstream static_pools {
    server 192.168.119.130:80;
}
upstream dynamic_pools {
   server 192.168.119.133:80;
}

    server {
        listen       80;
        server_name  www.test.com;
        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://dynamic_pools;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location /image {
            proxy_pass http://static_pools;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
[root@lb01 /]# nginx -s reload

在客户端测试

修改客户机/etc/hosts

C:\Windows\System32\drivers\etc\hosts

192.168.119.128    www.test.com

 访问

静态页面

动态页面

方法二：根据扩展名实现动静分离

由于测试环境没有做lnmp所以不适用这个代码 使用下面的代码

upstream static_pools {
    server 192.168.119.130:80;
}
upstream dynamic_pools {
   server 192.168.119.133:80;
}

    server {
        listen       80;
        server_name  www.test.com;
        location / {
            root   html;
            index  index.html index.htm;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location ~ .*.(gif|jpg|jpeg|png|bmp|swf|css|js)$ {
            proxy_pass http://static_pools;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location ~ .*.(php|php3|php5)$ {
           proxy_pass http://dynamic_pools;
           proxy_set_header Host $host;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        }

    }

 使用正则匹配（这里使用这个）

upstream static_pools {
    server 192.168.119.130:80;
}
upstream dynamic_pools {
   server 192.168.119.133:80;
}

    server {
        listen       80;
        server_name  www.test.com;
        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://dynamic_pools;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location ~ .*.(gif|jpg|jpeg|png|bmp|swf|css|js)$ {
            proxy_pass http://static_pools;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
