爲什麼使用通配符能指一秒鐘「服務器名稱」確實打破我的nginx的配置

Question

這個配置正常工作按預期：

server { 
      listen  80; 
      server_name www.domain1.com domain1.com; 

      access_log /srv/www/domain1.com/logs/access.log; 

      location/{ 
       root /srv/www/domain1.com/public_html; 
       index index.html index.htm; 


    } 
    } 
    server { 
      listen  80; 
      server_name domain2.com www.domain2.com; 

      access_log /srv/www/domain2.com/logs/access.log; 

      location/{ 
       root /srv/www/domain2.com/public_html; 
       index index.html index.htm; 


    } 
    } 

訪問時http://domain2.com這個配置顯示從domain1的內容：

server { 
      listen  80; 
      server_name *.domain1.com; 

      access_log /srv/www/domain1.com/logs/access.log; 

      location/{ 
       root /srv/www/domain1.com/public_html; 
       index index.html index.htm; 


    } 
    } 
    server { 
      listen  80; 
      server_name *.domain2.com; 

      access_log /srv/www/domain2.com/logs/access.log; 

      location/{ 
       root /srv/www/domain2.com/public_html; 
       index index.html index.htm; 


    } 
    } 

我覺得我在兩種情況下都正確遵循docs。

什麼會導致在示例二中使用通配符的意外行爲？

Answer 1

*.domain2.com不符合domain2.com。這樣做：

server_name domain2.com *.domain2.com;
