nginx redirect url to new pattern

问题:

I'm currently switching my blog from Wordpress to Ghost. There is nginx in front of ghost. After migration i recognized that old urls

http://domain.org/2015/10/some-topic

are migrated like

http://domain.org/some-topic

So date is gone. Anyway there is some backlinking i don't want to loose, but i'm not so familiar with nginx...So what is the best way to redirect from old url style to new?

My curent configuration looks like:

server {
            listen 80;
            server_name domain.org;

            location / {
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header HOST $http_host;
             proxy_set_header X-NginX-Proxy true;

            proxy_pass http://10.240.0.2:2368;
            proxy_redirect off;
            }
    }

What should be added?. I suppose i need new location but how it should look like?

I would recommend using a map:

map $uri $redirect_topic {
    "~^/\d{4}/\d{2}/(?<topic>.*)" $topic;
}

server {
    listen 80;
    server_name domain.org;

    if ($redirect_topic) {
        return 301 $scheme://$host/$redirect_topic;
    }

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header HOST $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass http://10.240.0.2:2368;
        proxy_redirect off;
    }
}

I think you should put into server section:

rewrite ^/[0-9]*/[0-9]*(/.*) $1 last;

But if you've any additional requests maybe would better in a location section (as you wrote).

About more information see on the official nginx documentation.
