1.准备站点目录

for i in {android,iphone,firefox,chrome,default} ;do mkdir /html/terminal/${i} && echo $i >/html/terminal/${i}/index.html ;done

2.准备配置文件

[root@RainGod conf.d]# cat android.conf  chrome.conf  default.conf  firefox.conf  iphone.conf  
server{
        listen 91;
        root /html/terminal/android;
        index index.html;
}
server{
        listen 92;
        root /html/terminal/chrome;
        index index.html;
}
server{
        listen 93;
        root /html/terminal/default;
        index index.html;
}
server{
        listen 94;
        root /html/terminal/firefox;
        index index.html;
}
server{
        listen 95;
        root /html/terminal/iphone;
        index index.html;
}

3.准备负载均衡 配置文件

[root@RainGod conf.d]# cat terminal.conf 
upstream firefox {
        server 127.0.0.1:94;
    }
    upstream chrome {
        server 127.0.0.1:92;
    }
    upstream iphone {
        server 127.0.0.1:95;
    }
    upstream android {
        server 127.0.0.1:91;
    }
    upstream default {
        server 127.0.0.1:93;
    }

#//server根据判断来访问不同的页面
server {
    listen       80;
    server_name  terminal.yangyijing.cn;
    access_log /var/log/nginx/terminal_access.log main;
    error_log  /var/log/nginx/terminal_error.log warn;

    #safari浏览器访问的效果
    location / {
#        if ($http_user_agent ~* "Safari"){
#        proxy_pass http://dynamic_pools;
#        }     
    #firefox浏览器访问效果
        if ($http_user_agent ~* "Firefox"){
        proxy_pass http://firefox;
        }
    #chrome浏览器访问效果
        if ($http_user_agent ~* "Chrome"){
        proxy_pass http://chrome;
        } 
        
    #iphone手机访问效果
        if ($http_user_agent ~* "iphone"){
        proxy_pass http://iphone;
        }
    
    #android手机访问效果
        if ($http_user_agent ~* "android"){
        proxy_pass http://android;
        }
    
    #其他浏览器访问默认规则
        proxy_pass http://default;
        include proxy_params;
        }
    }

访问测试
