nginx-动静分离

zhangfushuai 2021-05-24 09:14 原文

1.根据URI实现负载均衡

1.1架构设计
用户请求（URI）处理请求服务器站点目录功能
/upload 10.0.0.8:80 /html/www/upload upload服务器
/static 10.0.0.7:80 /html/www/static static静态服务器
/ 10.0.0.9:80 /html/www 默认
1.2服务器设置
1.2.1web02进行环境部署
[root@web01-172.16.1.8 ~]# mkdir /html/www/upload -p
[root@web01-172.16.1.8 ~]# echo "upload-web集群-10.0.0.8" >>  /html/www/upload/shuai.html
[root@web01-172.16.1.8 ~]# cat /html/www/upload/shuai.html
upload-web集群-10.0.0.8
[root@web02-172.16.1.8 /etc/nginx/conf.d]# vim blog.conf
server{
    listen    80;
    server_name   www.ashuai.com;

    location / {
        root  /html/www/;
           index shuai.html index.html;
   }
}

1.2.2web01进行环境部署

[root@web01-172.16.1.7 ~]# mkdir /html/www/static -p
[root@web01-172.16.1.7 ~]# echo "static-web集群-10.0.0.7" >>  /html/www/static/shuai.html
[root@web01-172.16.1.7 ~]# cat /html/www/static/shuai.html
static-web集群-10.0.0.7
[root@web01-172.16.1.7 /etc/nginx/conf.d]# vim blog.conf
server{
    listen    80;
    server_name   www.ashuai.com;
​
    location / {
        root  /html/www/;
        index  shuai.html  index.php;
    }
}

1.2.3web03进行环境部署

[root@web01-172.16.1.7 ~]# mkdir /html/www -p
[root@web01-172.16.1.7 ~]# echo "default-web集群-10.0.0.9" >>  /html/www/shuai.html
[root@web01-172.16.1.7 ~]# cat /html/www/shuai.html
default-web集群-10.0.0.9
[root@web03-172.16.1.9 /etc/nginx/conf.d]# vim blog.conf
server{
    listen    80;
    server_name   www.ashuai.com;
​
    location / {
        root  /html/www;
        index shuai.html  index.html;
    }
}

1.2.4配置负载均衡

[root@lb01-10.0.0.5 /etc/nginx/conf.d]# vim proxy.conf
upstream upload {
server 10.0.0.8:80;
}
upstream static {
server 10.0.0.7:80;
}
upstream default {
server 10.0.0.9:80;
}
server {
listen 80;
server_name www.ashuai.com;
location /upload {
proxy_pass http://upload;
proxy_set_header Host $host;
}
location /static {
proxy_pass http://static;
proxy_set_header Host $host;
}
location / {
proxy_pass http://default;
proxy_set_header Host $host;
}
}
[root@lb01-10.0.0.5 /etc/nginx/conf.d]# nginx -s reload
​

2.根据用户访问的终端显示不同页面

http_user_agent

2.1 架构设计
用户请求端处理请求服务器站点目录
iPhone 10.0.0.8:80 /html/www/
google 10.0.0.7:80 /html/www/
360 10.0.0.9:80 /html/www
2.2服务器设置
2.2.1web01环境部署
echo "iphone_access 10.0.0.7" >/html/www/shuai.html

2.2.2web02环境部署

echo "google_access 10.0.0.8" >/html/www/shuai.html

2.2.3web03环境部署

echo "360browser_access 10.0.0.7" >/html/www/shuai.html

2.2.4编写负载均衡配置文件

  [root@lb01-10.0.0.5 /etc/nginx/conf.d]# cat proxy.conf
upstream  iphone  {              
  server  10.0.0.7:80;
}
upstream google {              
  server  10.0.0.8:80;
}
upstream default {              
  server  10.0.0.9:80;
}



server  {
listen 80;
server_name www.ashuai.com;
location / {
    if ($http_user_agent ~*  iphone){
  
       proxy_pass http://iphone;


}

    if ($http_user_agent ~*  Chrom){

       proxy_pass http://google;


}

       proxy_pass http://default;       
       proxy_set_header Host $host;
 }
}
