How to redirect domain aliases through Nginx?

Question

Nginx

The domain has several aliases.
server_name site1.ru site2.ru site3.ru

I need to redirect site1.ru/page for example to google.com
And site2.ru/landing Redirect to yandex.ru

if ($http_host = 'site1.ru') {
    rewrite ^(.*) https:/google.com permanent;
  }

if ($http_host = 'site2.ru') {
    rewrite ^(.*) https://yandex.ru permanent;
  }

Is there another option to get by with one block?

Answer 1

Why do with one block if your processing is different? Ceteris paribus, it is better to make separate server blocks than to crutch with ifs.
