我已经做了所有的search，但没有运气。 我试图找出如何为用户创build一个名称空间，说user.mysite.com，并有redirect到他/她的文件夹（mysite.com/user）。 有没有办法使nginx转发所有子域到他们各自的文件夹？ 我这样做的原因是因为我希望能够使这样的子域名，而不必重新启动nginx。
我的nginx.conf文件看起来像这个FYI。
server { # add www. if ($host ~ ^(?!www)) { rewrite ^/(.*)$ http://www.$host/$1 permanent; } server_name www.mydomain.com; access_log /var/log/nginx/mydomain.com.access.log; error_log /var/log/nginx/mydomain.com.error.log; root /usr/share/nginx/mydomain.com/; index index.php index.html index.htm; # use fastcgi for all php files location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # deny access to apache .htaccess files location ~ /\.ht { deny all; } } 这是我发现将所有子域名redirect到www.mydomain.com的一小段代码。 如果它可以redirect到各自的目录，而不是我所需要的。
# remove subdomain if ($host ~ "^www\.(.*?)\.(.{3,}\.([az]{2}\.[az]{2}|[az]{2,4}))$") { set $host_without_sub $2; rewrite ^/(.*)$ http://www.$host_without_sub/$1 permanent; }
再过了一整天的search结果，我发现这个gem：
