##### 执行上述资源清单

### 找出 IP
[root@master kubernetes]# kubectl get pod -o wide
NAME                       READY  RESTARTS   AGE    IP          NODE     NOMINATED NODE  
wp-mysql57                  2/2      0       70m    10.2.3.17   node03   <none>          
nginx-565785f75c-hn9ql      1/1      0       106m   10.2.3.13   node03   <none>          


### 利用集群做出反向代理
[root@node02 ~]# yum install nginx -y
[root@node02 ~]# rm /etc/nginx/conf.d/*
[root@node02 ~]# vim /etc/nginx/conf.d/wp。conf
server {  
    listen 80;  
    server_name _;  
  
    location / {    
        proxy_pass http://10.2.3.17:80;  
        proxy_set_header Host $host;  
        proxy_set_header X-Real-IP $remote_addr;  
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  
        proxy_set_header X-Forwarded-Proto $scheme;  
  
        # 可选：如果你需要处理WebSocket连接  
        proxy_http_version 1.1;  
        proxy_set_header Upgrade $http_upgrade;  
        proxy_set_header Connection "upgrade";  
  
        # 其他代理设置...  
    }  
  
    # 其他location块...  
  
    # 错误页面处理  
    error_page 500 502 503 504 /50x.html;  
    location = /50x.html {  
        root /usr/share/nginx/html;  
    }  
}
