nginx 将所有通配符子域重写为 www.site.com [英] nginx rewrite all wildcard subdomains to www.site.com

问题描述

使用 nginx，我想将 example.com 的所有子域重定向到 www.example.com.

Using nginx, I want to redirect all subdomains of example.com to www.example.com.

我在这里看到重定向将非 www 重定向到 www 或反之亦然，但我也希望 www2.site.com blabla.site.com 被重定向.我有一个域的通配符 dns.

I have seen redirects here to redirect non-www to www or vise versa, but I also want www2.site.com blabla.site.com to be redirected. I have a wildcard dns for the domain.

对于 apache，这可以通过以下方式轻松完成:

For apache this can be done easily with following:

RewriteCond %{HTTP_HOST} !www.example.com [NC]
RewriteRule (.*) http://www.example.com%{REQUEST_URI} [R=301,L]

以下似乎有效，但根据 ifisevil 页面，不建议这样做.

The below seem to work, but it is not recommended according to the ifisevil page.

if ($http_host !~ "www.site.com"){
    rewrite ^(.*)$ http://www.example.com$request_uri redirect;
}

推荐答案

在 nginx 中做到这一点的最佳方法是结合两个服务器块:

The best way to do this in nginx is with a combination of two server blocks:

server {
  server_name *.example.org;
  return 301 $scheme://example.org$request_uri;
}

server {
  server_name www.example.org;

  #add in further directives to serve your content
}

我已经在我的笔记本电脑上测试过这个，因为你报告它不起作用.我在本地得到以下结果(在将 www2.test.localhost 和 www.test.localhost 添加到我的 /etc/hosts 之后，以及nginx 配置位，并重新加载 nginx):

I have tested this on my laptop, since you reported it not working. I get the following result locally (after adding www2.test.localhost and www.test.localhost to my /etc/hosts, along with the nginx config bit, and reloading nginx):

$ curl --head www2.test.localhost
HTTP/1.1 301 Moved Permanently
Server: nginx/1.2.6
Date: Thu, 07 Mar 2013 12:29:32 GMT
Content-Type: text/html
Content-Length: 184
Connection: keep-alive
Location: http://www.test.localhost/

所以是的，这绝对有效.

So yes, this definitely works.
