方式一：两个域名分开写
server { listen 80; server_name example.org; return 301 http://www.example.org$request_uri; } server { listen 80; server_name www.example.org; ... }
方式二：两个域名写一起
server { listen 80; server_name example.com www.example.com; # 跳转到www if ($host = 'example.com' ) { rewrite ^(/.*)$ http://www.example.com$1 permanent; } }
或者
server { listen 80; server_name example.com www.example.com; # 跳转到www if ($host ~ '^example.com'){ return 301 https://www.example.com$request_uri; } }
