nginx二级域名配置自动跳转到一级域名

rewrite配置内容：if ($http_host !~ "^www.aaa.com$") {

          rewrite^(.*)    http://www.aaa.com$1 permanent;
}

 

下方，nginx代理访问项目proxy_pass，及rewrite参考

server

{

    listen80;

    server_name www.aaa.com100.100.100.100;

    location/{if ($http_host !~ "^www.aaa.com$") {

          rewrite^(.*)    http://www.aaa.com$1 permanent;
}

        proxy_redirect off;

        proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://192.168.1.2:8000;
}

    access_log logs/aaa.com_access.log;
}
