Example 301 redirection configuration for domain name and directory in nginx

301 redirection is not unknown, sometimes there is a need to redirect a directory to 1 level 2 domain name, or not with www top-level domain request all redirection to www level 2 domain name. If it is Apache, need to configure.htaccess, nginx does not support, need to use rewrite command in the configuration file to achieve.

Top-level domain redirects to www

server {

 server_name ofstack.com;

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

 }

ofstack.com requests are redirected to www.ofstack.com,301 redirects are helpful for SEO. This configuration is most commonly used.

The www2 level domain is redirected to the top-level domain

server {

 server_name www.ofstack.com;

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

 }

Some seoer requests that operations 1 transfer www's request to the 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 plans to create a domain name.

Attachment: 301 jumps between domains and test methods

1. Jump between the same root domain and subdomain

Case 1: access to the root domain is redirected to the www subdomain (Vhost is usually bound to multiple domain names, so that it can be accurately located to a domain name without causing the non-domain name to jump to this domain name)

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

2. 301 jumps between different domains

Case 1: visit A station and direct to B station

server {

    server_name www.ofstack.com;

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

}

Case 2: not all redirects to the specified page for access to the A site

server {

    server_name www.ofstack.com;

    if ($host != 'ofstack.com') {

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

    }

}

If I write it in the first server
Access using IP will also be redirected
