Nginx：將網站遷移到新域名

Question

我有一個運行WordPress的網站example.com。現在，我想搬到這個博客子域blog.example.com，但我也想以下幾點：

example.com --> static page (not wordpress) 

blog.example.com --> new address to the blog 
blog.example.com/foo --> handled by wordpress 

example.com/foo --> permanent redirect to blog.example.com/foo 

所以，我想這下配置：

server { 
      server_name example.com; 

      location =/{ 
        root /home/path/to/site; 
      } 

      location/{ 
        rewrite ^(.+) http://blog.example.com$request_uri? permanent; 
      } 
    } 

在這種情況下重定向可以正常使用。不幸的是，example.com也重定向到blog.example.com。

Answer 1

它轉向的原因是因爲當它試圖加載索引文件example.com，它執行內部重定向到/index.html，這是由您的重寫位置處理。爲了避免這種情況，你可以使用try_files：

server { 
    server_name example.com; 

    root /home/path/to/site; 

    location =/{ 
    # Change /index.html to whatever your static filename is 
    try_files /index.html =404; 
    } 

    location/{ 
    return 301 http://blog.example.com$request_uri; 
    } 
} 

Answer 2

只要兩個域的根將指向不同的目錄，你會需要兩個server指令 - 這樣的事情：

server { 
     # this is the static site 
     server_name example.com; 

     location =/{ 
       root /home/path/to/static/page; 
     } 

     location /foo { 
       return 301 http://blog.example.com$request_uri; 
     } 
} 

server { 
     # this is the WP site 
     server_name blog.example.com; 

     location =/{ 
       root /home/path/to/new_blog; 
     } 

     .... some other WP redirects ..... 
}
