I had once moved my blogger site to wordpress. Till then I had to use the following in .htaccess file.
RedirectMatch 301 ^/([0-9]{4})/([0-9]{2})/([^/]+).html$ http://mywpsite.com/$3
Now, after moving my site to Nginx, I could not find a way to implement the above rule so that my old permalinks are maintained in new environment also.
You can use nginx's rewrite directive to implement that:
rewrite ^/([0-9]{4})/([0-9]{2})/([^/]+).html$ http://mywpsite.com/$3 permanent;
I added the code inside the server block but getting error.
nginx -t
nginx: [emerg] directive "rewrite" is not terminated by ";" in /etc/nginx/sites-enabled/wordpress:67
Although, the semi-colon is placed in the code above.
The Nginx rewrite docs state:
Note: for curly braces( { and } ), as they are used both in regexes and for block control, to avoid conflicts, regexes with curly braces are to be enclosed with double quotes (or single quotes).
So try,
rewrite "^/([0-9]{4})/([0-9]{2})/([^/]+).html$" http://mywpsite.com/$3 permanent;
The solution above worked partially.
Example:-
http://mywpsite.com/2011/08/one-of-my-post-link.html -> http://mywpsite.com/one-of-my-post-link/ (Success)
http://www.mywpsite.com/2011/08/one-of-my-post-link.html -> http://www.anotherdomain.com/2011/08/one-of-my-post-link.html (failure)
