Wordpress nginx redirect loop

Question

So, yesterday I had a question how to install the wordpress in the "/root" directory. I wasn't very successful in that one and I forgo'ed on that one.

So, right now the wordpress is located under "/var/www/wordpress" (so it's under separate folder) folder (I use Ubuntu 12.04 LTS, if it matters).

And my problem is that right after I had configured everything (everything was working like a charm there) I was redirected to the admin panel page. Everything was working fine up until the moment when I tried to visit the blog.

The URL address for my blog is: "blog.mysite.com". That is why I use NGINX, because I have two different applications (and environments) on one server and I need to distinguish between them.

So, the fact is: blog.mysite.com/wp-admin (/wp-login.php) is working totally OK, but when I visit the front page: blog.mysite.com, it keeps telling me that there is an endless redirect loop (301 redirect according to nginx access log file).

In admin panel I have both "WordPress Address (URL)" and "Site address (URL)" set to: "http://blog.mysite.com". Modifying either of them to something else, like: "http://blog.mysite.com/wordpress" is not helping at all!

".htaccess" file is empty, but I'm using default permalinks, so should not be a problem (However, I'm not sure).

Both nginx and apache2 root directives are pointing to "/var/www/wordpress". Static files (css,js) are working, if it matters.

How can I fix this problem ? Any help is much appreciated!

Thank you in advance!

Answer 1

I had a similar problem using Nginx as a reverse proxy for Apache.

After a few hours I found out it was caused by the $_SERVER["REQUEST_URI"] being set to index.php by Nginx instead of the actual url and Wordpress was trying to remove index.php by redirecting to the url without index.php in wp-includes/canonical.php.

The solution for me is using something like this,

proxy_pass http://111.111.111.111:8080$request_uri;

So adding the $request_uri fixed it.

Not the prettiest fix, but removing the redirect filter in your theme functions.php file worked for me.

remove_filter('template_redirect', 'redirect_canonical');
