# Nginx 無痛升級
我不最終不確定這個方案，因為在切換不同的伺服器的話，chorme 或者 其他的瀏覽器，除非發生url 的跳轉 等等之類的相關因素 ，是無法 即時更新伺服器的，目前有待深入研究不過初始架構就是 基於 負載平衡這樣，好想趕快學寫伺服器腳本等等之類的喔，

在這張圖 初步規畫與實現 非常簡單,

1. 在http节点下，添加upstream节点。

upstream favtomcat {

server 192.168.1.1:8080 weight = 1;  

server 10.0.6.108:7080 weight = 4;  

server 10.0.6.108:7080 backup;  

}

2. 将server节点下的location节点中的proxy_pass配置为：http:// + upstream名称，即“

http://favtomcat”.
location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://favtomcat;
}
