How to redirect a URL in Nginx

nginx, redirect, url-rewriting

Solution

Best way to do what you want is to add another server block:

server {
        #implemented by default, change if you need different ip or port
        #listen *:80 | *:8000;
        server_name test.com;
        return 301 $scheme://www.test.com$request_uri;
}

And edit your main server block server_name variable as following:

server_name  www.test.com;

Important: New `server` block is the right way to do this, `if` is evil. You must use locations and servers instead of `if` if it's possible. `Rewrite` is sometimes evil too, so replaced it with `return`.

Problem

I need to redirect every http://test.com request to http://www.test.com. How can this be done. In the server block I tried adding ``` rewrite ^/(.*) http://www.test.com/$1 permanent; ``` but in browser it says The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. My server block looks like ``` server { listen 80; server_name test.com; client_max_body_size 10M; client_body_buffer_size 128k; root /home/test/test/public; passenger_enabled on; rails_env production; #rewrite ^/(.*) http://www.test.com/$1 permanent; #rewrite ^(.*)$ $scheme://www.test.com$1; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } ```
