 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:\Program\fzjh\nginx-1.15.2\nginx.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:\Program\fzjh\nginx-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)

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
