Example of 301 redirection configuration for domain names and directories in nginx

301 redirection is not unknown, sometimes there is a need to redirect the entire directory to 1 2-level domain, or the top-level domain without www requests all redirection to the 2-level domain with www.

The top-level domain is redirected to www

server {

 server_name ofstack.com;

 rewrite ^/(.*)$ //www.ofstack.com/$1 permanent;

 }

The above configuration so that requests for ofstack.com will be redirected to www.ofstack.com,301 is helpful for SEO.

www2-level domain redirects to the top-level domain

server {

 server_name www.ofstack.com;

 rewrite ^/(.*)$ http://domain.com/$1 permanent;

 }

Some seoer will require operations 1 to transfer www's request to a top-level domain, as opposed to the above.

directory redirection

if ( $request_filename ~ nginxjiaocheng/ ) {

 rewrite ^ //www.ofstack.com/nginx/? permanent;

 }

directory jumps to new domain name

if ( $request_filename ~ nginx/ ) {

 rewrite ^ http://nginx.ofstack.com/? permanent;

}

nginx is so popular that it's going to have a domain name.

attachment: 301 jumps between domains and test method

1. Jump between the same root domain and subdomain

Case 1: access to the root domain redirect to the www subdomain (Vhost is usually bound to more than one domain name, this can accurately locate a domain name, will not cause the non-domain to jump to this domain)

server {
      server_name www.ofstack.com ofstack.com;
      if ($host = 'ofstack.com' ) {
              rewrite ^/(.*)$ //www.ofstack.com/$1 permanent;
      }

2. 301 jump between different domains

Case 1: visit A station and be directed to B station

server {

    server_name www.ofstack.com;

    rewrite ^(.*) //www.ofstack.com$1 permanent;

}

Case 2: not all redirects to the specified page that access the A station

server {

    server_name www.ofstack.com;

    if ($host != 'ofstack.com') {

        rewrite ^/(.*)$ //www.ofstack.com/$1 permanent;

    }

}

If it's in the first server paragraph
Access using IP will also be redirected
