下nginx搭建筑大可用,高并发的wcf集群

 3. client端的次第搭建

 

 

釜底抽薪智:打开解决方案NuGet包管理器,卸载一个让“Microsoft.CodeDom.Providers.DotNetCompilerPlatform”的保险,之后还编译网站,发现Bin目录下没有roslyn文件夹了!

   

坐windows的简单尊机械的ip地址是192.168.23.187,192.168.23.188,所以安排的上注意一下config中的baseAddress地址。

多年来新提升了Visual Studio
2017,创建的Web项目Bin目录中大多了一个受roslyn的文书夹,该文件夹导致网站在某些服务器上颁发出错

[root@localhost nginx]# cd conf
[root@localhost conf]# ls
fastcgi.conf            koi-utf             nginx.conf           uwsgi_params
fastcgi.conf.default    koi-win             nginx.conf.default   uwsgi_params.default
fastcgi_params          mime.types          scgi_params          win-utf
fastcgi_params.default  mime.types.default  scgi_params.default
[root@localhost conf]# vim nginx.conf

不过于服务器上安装.net4.6晚依旧提示编译出错。

 

 

无异于:准备的素材

  1. 话不多说,一贪图胜千言,图备受之服务器都是运用vmware虚拟化,如下图:

由网上搜了转,Roslyn是初出之动态编译工具

 

 

   
nginx我怀念大家于是之尚是于多的,去官网下载最新的尽管哼【nginx-1.13.6】:http://nginx.org/en/download.html,下载后,就是正常的三板斧安装!!!

 

    

 

《2》 App.Config代码

    既然是测试,肯定就是概括的顺序,代码就不全让闹了。

 

 

 

  1. centos上的nginx搭建
[root@localhost nginx-1.13.6]# ./configure --prefix=/usr/myapp/nginx
[root@localhost nginx-1.13.6]# make && make install

第二:环境搭建

《1》
HomeService实现类代码如下(输出当前server的ip地址,方便查看):

冀本篇对君有帮助~~~~
  附完整源代码:cluster.zip   
 

你的载重机制粒度很粗劣的语,优先采取nginx就好搞定,既可以实现复杂均衡,又足以兑现双机热备,以极端小之代码量实现我们的作业,下面具体享受下。

 

     

 

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <configuration>
 3   <startup>
 4     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
 5   </startup>
 6   <system.serviceModel>
 7     <behaviors>
 8       <serviceBehaviors>
 9         <behavior name="">
10           <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
11           <serviceDebug includeExceptionDetailInFaults="false" />
12         </behavior>
13       </serviceBehaviors>
14     </behaviors>
15     <services>
16       <service name="WcfService.HomeService">
17         <endpoint address="/HomeService" binding="basicHttpBinding" contract="WcfService.IHomeService">
18           <identity>
19             <dns value="localhost" />
20           </identity>
21         </endpoint>
22         <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
23         <host>
24           <baseAddresses>
25             <add baseAddress="http://192.168.23.187:8733" />
26           </baseAddresses>
27         </host>
28       </service>
29     </services>
30   </system.serviceModel>
31 </configuration>

    然后在nginx的装置目录下面找到conf文件,修改中的nginx.conf 配置。

《2》
然后就是client端程序添加服务引用,因为添加了host映射,所以服务引用地址便是”http://cluster.com"。
代码如下:

   
详细部署如下,注意下面“标红”的地方,权重按照1:5底方式展开调用,关于任何的布,大家好在网上搜一下哪怕得了。

192.168.23.190 cluster.com

《1》 第一项事便是拿 192.168.23.190
映射到本机的host中错过,因为劳动不提供被第三方以,所以加host还是蛮自在的。

终极来施行以下顺序,看看1000不行巡回中,是匪是以权重1:5
的措施对后端的wcf进行调用的???

       
很多动静下基于wcf的扑朔迷离均衡且首选zookeeper,这样可拥有再好的控制粒度,但zk对C#
不老和谐,实现起来相对来说比较麻烦,实际情形下,如果

《3》在所有的Client葡京网上娱乐场的Hosts文件被多host映射:【192.168.23.190
cluster.com】,方便通过域名的款式拜访nginx所当服务器的ip地址。

瞧没有,是无是坏牛逼,我只是待经过cluster.com进行劳动走访,nginx会自动为自己复杂均衡,这就算是我们开中非常简单化的wcf复杂均衡。
