C#負載均衡 windows下實現簡單負載均衡(無實際意義)

 轉載自 https://www.cnblogs.com/edisonchou/p/4126742.html#!comments 

 因博主說的不太清楚,搭了半天才搞明白

然后自己簡化總結了一下方案

手快的話三分鍾搭好

 

一:站點

 沒有直接搭建iis

用的vs自帶的iis

 

現在有三個站點:

http://localhost:8050

http://localhost:8060

http://localhost:8070

 分別名為 "第一台web服務器"|"第二台web服務器"|"第三台web服務器"

 

二: 搭建Nginx

 從https://www.baidu.com/link?url=GKGrcD0YIrE7fvwXXDuhEY46Ni2eAmVNFBs_kD2tN1a&wd=&eqid=dc0997710000ae06000000035b738605下載

我解壓后放在了

 

"E:\Program\fzjh\nginx-1.15.2\nginx.exe"

之后打開cmd,依次輸入

E: //然后回車,目的是跳轉到E盤

cd E:\Program\fzjh\nginx-1.15.2\                     //跳轉到當前exe所在的文件目錄

start nginx.exe

然后打開Http://localhost

沒什么意外應該顯示

 

這說明nginx已經啟動成功

然后修改conf目錄下的nginx.conf

我的配置給大家伙先展示下,隨后再貼出要改的地方

最后需要在cmd里重啟nginx:

nginx -s reload

 

 

 

 

(注:不能用記事本打開nginx.conf,我用的是windows自帶的寫字板,但是粘貼之后保存也會出錯,最后只能純手打了)

    }

    #    location / {

    #    }
    #}

    #    listen       443 ssl;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

 

下面是需要改的地方

 

 

大體上就是upsteams 的name 與proxy_pass的值對應,(但要多加一個http://)

然后 index的默認頁面要和你的站點的默認頁面對應

最后,重啟nginx后(nginx -s reload)再去訪問http://localhost/

簡單的負載均衡就這樣子實現了

 

不過據說

IIS 做負載均衡最好是用Windows Server 自帶的組件NLB

或者就是簡單的iis自帶的server frame

所以這個nginx就是當玩玩了

不過中小型的網站也是可以用這個的,

最起碼搭着簡單啊
