Nginx Redirect (Rewrite) Old Domain To New Domain With HTTP 301

To redirect an old domain to a new domain with an HTTP 301 Moved Permanently header in Nginx, you can use the server_name directive and the return or rewrite directive inside the server block in the Nginx configuration file.

For example, to redirect all requests for http://old-domain.com to http://new-domain.com, you can add the following configuration to your Nginx configuration file:

server {
    listen 80;
    server_name old-domain.com;

    return 301 http://new-domain.com$request_uri;
}

This will redirect all requests for http://old-domain.com to http://new-domain.com with an HTTP/1.1 301 Moved Permanently header.

Alternatively, you can use the rewrite directive to achieve the same result:

server {
    listen 80;
    server_name old-domain.com;

    rewrite ^ http://new-domain.com$request_uri permanent;
}

Keep in mind that you will need to reload or restart Nginx for the changes to take effect.

service nginx reload

Note: If you want to redirect specific URLs or paths within the old domain to specific URLs or paths within the new domain, you can use the location directive and the return or rewrite directive inside the server block.

For example, to redirect http://old-domain.com/old-path to http://new-domain.com/new-path, you can use the following configuration:

server {
    listen 80;
    server_name old-domain.com;

    location /old-path {
        return 301 http://new-domain.com/new-path;
    }
}

server {
    listen 80;
    server_name old-domain.com;

    location /old-path {
        rewrite ^ http://new-domain.com/new-path permanent;
    }
}

This will redirect all requests for http://old-domain.com/old-path to http://new-domain.com/new-path.
