GitHub页面的Nginx代理？

Question

我们有一个博客,我们在github上与Jekyll一起主持; 它在那里:http://blog.superfeedr.com

理想情况下,我希望它在http://superfeedr.com/blog/,因为我们需要添加一些AJAX,我们需要避免"同源策略"问题.

我们在"主"网络服务器上使用Nginx,我有以下设置:

location /blog/ {

proxy_pass http://blog.superfeedr.com/;
    proxy_redirect     off;
    proxy_max_temp_file_size 0;

    client_max_body_size       10m;
    client_body_buffer_size    128k;

    proxy_connect_timeout      90;
    proxy_send_timeout         90;
    proxy_read_timeout         90;

    proxy_buffer_size          4k;
    proxy_buffers              4 32k;
    proxy_busy_buffers_size    64k;
    proxy_temp_file_write_size 64k;
}

不幸的是,正如你可以看到你去http://superfeedr.com/blog/这显然不起作用.奇怪的是,我们被重定向到Github的主页.

PS:显然,我们可以在我们的主服务器上托管博客,但目标是将其托管在不同的主机上,以便我们几乎可以保证它在网站停机时在线...

首先,nginx不会将host头发送到blog.superfeedr.com.这使它发送所有必需的标题:

proxy_set_header   Host                    blog.superfeedr.com;
proxy_set_header   X-Host                 blog.superfeedr.com;
proxy_set_header   X-Real-IP             $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;

其次,需要一些网址重写.由于一些奇怪的原因,这取决于您使用的nginx的版本.无论如何,对于0.6.x(对我来说是0.6.32),这应该工作:

    location /blog {
                rewrite  ^/blog(.*)$ /$1 last;
                error_page 402 = @blog;
                return 402;
    }
    location @blog {
        proxy_pass http://blog.superfeedr.com;

        # the rest of proxying parameters should be here

         proxy_set_header   Host                    blog.superfeedr.com;
         proxy_set_header   X-Host                 blog.superfeedr.com;
         proxy_set_header   X-Real-IP $remote_addr;
         proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
    }

您还需要涵盖博客所引用的所有路径(例如,css,图像等)

location /css {
    error_page 402 = @blog;
    return 402;
}

对于0.7.59:

        location /blog {
                set $blog 1;
                rewrite  ^/blog(.*)$ /$1 last;
        }
        location /css {
                set $blog 1;
                error_page 402 = @blog;
                return 402;
        }
        location / {
                if ($blog) {
                        error_page 402 = @blog;
                        return 402;
                }
                # here is where default settings for / should be
                root /usr/local/www/nginx/;
        }
        location @blog {
                proxy_pass http://blog.superfeedr.com;

                # the rest of proxying parameters should be here

                proxy_set_header   Host                   blog.superfeedr.com;
                proxy_set_header   X-Host                 blog.superfeedr.com;
                proxy_set_header   X-Real-IP $remote_addr;
                proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        }
