使用Varnish配置多个站点 [英] Configure multiple sites with Varnish

问题描述

我们有一个服务器，需要服务多个域，虽然varnish例如。 example1.com，example2.com和example3.com

We have a server which needs to serve multiple domains though varnish e.g. example1.com, example2.com and example3.com

我们当前的.vcl文件如下所示：

Our current .vcl file looks like this:

sub vcl_recv {
  set req.http.Host = "example1.com";    
  lookup;
}

如何为正确的传入请求设置正确的req.http.Host

How do I set the correct req.http.Host for the correct incoming request?

推荐答案

您可以以这种方式支持多个前端网域：

You can support multiple frontend domains this way:

 backend example1 {
     .host = "backend.example1.com";
     .port = "8080";
 }
 backend example2 {
      .host = "backend.example2.com";
      .port = "8080";
 }
 sub vcl_recv {
    if (req.http.host == "example1.com") {
        #You will need the following line only if your backend has multiple virtual host names
        set req.http.host = "backend.example1.com";
        set req.backend = example1;
        return (lookup);
    }
    if (req.http.host == "example2.com") {
        #You will need the following line only if your backend has multiple virtual host names
        set req.http.host = "backend.example2.com";
        set req.backend = example2;
        return (lookup);
    }
 }
