nginx下强制跳转到www域名

#先监听 jerrychee.cn域名，然后转发到www下面
server {
  listen         80;
  server_name    jerrychee.cn;

  rewrite ^(.*) $scheme://www.$server_name$1 permanent;
}

#www.jerrychee.cn配置
server {
  listen       80;
  root         path;
  server_name  www.jerrychee.cn;
  
  location / {
    proxy_pass http://***.***.***.***:*****;
   }
}
