Nginx 重寫錯誤

Question

由於某些原因，www.server-1.com/forum 不會重新導向至 forum.server-1.com，而是重新導向至 www.server-2.com。當我刪除將www.server-1.com 重定向到www.server-2.com 的部分時，它就像一個魅力......好吧，不完全是，因為每當論壇get 之後的第一個斜線都會在過程中遺失。

# Redirect www.server-1.com/forum to forum.server-1.com
# Redirect www.server-1.com/forum/ to forum.server-1.com
# Redirect www.server-1.com/forums to forum.server-1.com
# Redirect www.server-1.com/forums/ to forum.server-1.com
# Redirect www.server-1.com to www.server-2.com
server {
  listen 80;

  server_name www.server-1.com;

  location = /forum {
    rewrite ^ http://forum.server-1.com redirect;
    break;
  }

  location /forum/ {
    rewrite ^/forum/(.*) http://forum.server-1.com$1 redirect;
    break;
  }

  location = /forums {
    rewrite ^ http://forum.server-1.com redirect;
    break;
  }

  location /forums/ {
    rewrite ^/forums/(.*) http://forum.server-1.com$1 redirect;
    break;
  }

  rewrite ^ http://www.server-2.com redirect;
}

# Redirect forum.server-1.com to www.server-3.com/forum (where the forum is hosted)
server {
  listen 80;

  server_name forum.server-1.com;

  rewrite ^(.*) http://www.server-3.com/forum$1 redirect;
}

# Redirect forums.server-1.com to forum.server-1.com
server {
  listen 80;

  server_name forums.server-1.com;

  rewrite ^(.*) http://forum.server-1.com$1 redirect;
}

# Redirect server-1.com and *server-1.com to www.server-1.com
server {
  listen 80;

  server_name server-1.com *.server-1.com;

  rewrite ^(.*) http://www.server-1.com$1 redirect;
}

nginx 不一定會依照指令在設定檔中出現的順序處理指令。伺服器級重寫指令將在位置選擇之前處理，這解釋了您所看到的行為。由於伺服器中的所有內容都只是重寫，因此您應該能夠使用它：

server {
  server_name www.server-1.com;

  rewrite ^/forums?(.*) http://forum.server-1.com$1 redirect;
  return 302 http://www.server-2.com/;
}
