在前面实验（[https://blog.csdn.net/qq\_35887546/article/details/104731132][https_blog.csdn.net_qq_35887546_article_details_104731132]）的基础上实现动静分离

实验流程如下：

# 1.修改配置文件 #

在server1：

[root@server1 ~]# vim /etc/haproxy/haproxy.cfg 
    
     61 # main frontend which proxys to the backends
     62 #---------------------------------------------------------------------
     63 frontend  westos *:80							#编辑前端和后端策略
     64     acl url_static       path_beg       -i /images				#表示url地址以/images开头时即认为时静态地址
     65     acl url_static       path_end       -i .jpg .gif .png		#表示url地址以.jpg .gif .png 结尾时即认为时静态地址
    
     66 
     67     use_backend static          if url_static
     68     default_backend             app				#其他默认为动态地址
     69 
     70 #---------------------------------------------------------------------
     71 # static backend for serving up images, stylesheets and such
     72 #---------------------------------------------------------------------
     73 backend static								#编辑静态策略
     74 #    balance     roundrobin
     75     server      static 172.25.63.3:80 check			#指定server3为静态页面服务器
     76 
     77 ##---------------------------------------------------------------------
     78 # round robin balancing between the various backends
     79 #---------------------------------------------------------------------
     80 backend app								  #编辑动态策略
     81     balance     roundrobin
     82     server  web1 172.25.63.2:80 check
     83     server  web2 172.25.63.1:8000 check
     84 #    server  app3 127.0.0.1:5003 check
     85 #    server  app4 127.0.0.1:5004 check
     86 
     87 listen admin *:8080
     88         stats enable
     89         stats uri /status       #监控页面地址
     90         stats auth admin:westos #管理帐号和密码
     91         stats refresh 5s        #刷新频率
     92 
     93 #listen westos *:80     #监听的实例名称，地址和端口
     94 #       balance roundrobin      #负载均衡算法
     95 #       server web1 172.25.63.2:80 check
     96 #       server web2 172.25.63.3:80 check

# 2.配置动态页面服务器server1 #

将server1配置为另外一台apache服务器：

[root@server1 ~]# yum install httpd -y
    [root@server1 ~]# cd /var/www/html/
    [root@server1 html]# vim index.html
    
    server1
    
    
    [root@server1 html]# vim /etc/httpd/conf/httpd.conf 		#由于server1同样也是haproxy代理服务器，为了防止端口冲突，将server1的htppd端口改为8000
    
     42 Listen 8000
    
    [root@server1 html]# systemctl start httpd				#注意，selinux必须关闭，要不然启动会报错

# 3.配置静态页面服务器server3 #

在sercer3apache发布目录放入测试文件：

[root@server3 html]# pwd
    /var/www/html
    [root@server3 html]# mkdir images
    [root@server3 html]# cd images/
    [root@server3 images]# ls
    123.jpg

# 4.测试 #

首先在server1重启haproxy服务：

[root@server1 html]# systemctl restart haproxy.service

## 测试动态页面 ##

在客户端：

[root@foundation63 ~]# curl 172.25.63.1
    server2
    [root@foundation63 ~]# curl 172.25.63.1
    server1
    [root@foundation63 ~]# curl 172.25.63.1
    server2
    [root@foundation63 ~]# curl 172.25.63.1
    server1

说明动态页面测试成功

## 测试静态页面 ##

在客户端浏览器访问`http://172.25.63.1/images/`：
