C#负载均衡 windows下实现简单负载均衡(无实际意义)

 转载自 https://www.cnblogs.com/edisonchou/p/4126742.html#!comments 

 因博主说的不太清楚,搭了半天才搞明白

然后自己简化总结了一下方案

手快的话三分钟搭好

一:站点

 没有直接搭建iis

用的vs自带的iis

现在有三个站点:

http://localhost:8050

http://localhost:8060

http://localhost:8070

 分别名为 "第一台web服务器"|"第二台web服务器"|"第三台web服务器"

二: 搭建Nginx

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

我解压后放在了

"E:Programfzjh ginx-1.15.2 ginx.exe"

之后打开cmd,依次输入

E: //然后回车,目的是跳转到E盘

cd E:Programfzjh ginx-1.15.2                     //跳转到当前exe所在的文件目录

start nginx.exe

然后打开Http://localhost

没什么意外应该显示

 

这说明nginx已经启动成功

然后修改conf目录下的nginx.conf

我的配置给大家伙先展示下,随后再贴出要改的地方

最后需要在cmd里重启nginx:

nginx -s reload

(注:不能用记事本打开nginx.conf,我用的是windows自带的写字板,但是粘贴之后保存也会出错,最后只能纯手打了)

        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ .php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ .php$ {

        #    fastcgi_pass   127.0.0.1:9000;

        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

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


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    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

 

大体上就是upsteams 的name 与proxy_pass的值对应,(但要多加一个http://)

然后 index的默认页面要和你的站点的默认页面对应

最后,重启nginx后(nginx -s reload)再去访问http://localhost/

简单的负载均衡就这样子实现了

不过据说

IIS 做负载均衡最好是用Windows Server 自带的组件NLB

或者就是简单的iis自带的server frame

所以这个nginx就是当玩玩了

不过中小型的网站也是可以用这个的,

最起码搭着简单啊
