Problem with moving posts with Nginx

Hello,

I've been using Nginx for awhile now and have had this issue. My workaround has been to simply switch off vBSEO when I need to move posts or merge threads and then switch it back on. This is obviously not a good long term solution.

I am using the following rewrites as per howto for nginx :

location /forums/ {

rewrite ^/forums/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /forums/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;

if ($request_filename ~ "\.php$" ) {
rewrite ^(.*)$ /forums/vbseo.php last;
}

if (!-e $request_filename) {
rewrite ^/forums/(.*)$ /forums/vbseo.php last;
}

}

When I attempt to move a post from one thread to another using the rewritten URL that ends in ".html" I get the following error message:

vBulletin Message

You have not specified a valid URL for the thread that you want to merge. Please check that the URL includes a valid threadid, "t=xxx" or postid, "p=xxx" (where xxx is a number), and is not a redirect.

Any ideas?

Hello,

looks like *.php requests are not preprocessed by vBSEO. Can you open a ticket with server access details for troubleshooting?

An update:
I've moved this section to the bottom of nginx config:

Code:

if ($request_filename ~ "\.php$" ) {
rewrite ^(.*)$ /forums/vbseo.php last;
}

It seems to work correctly now.

Oleg, I'm having the same problem. By: "I've moved this section to the bottom of nginx config:"

Do you mean that you moved it to the bottom of the directives within the location body for vbseo rewrites, or did you move it out of the location body and place it directly in the bottom of the config with no nesting/conditionals?

Thanks much.

To the bottom without any location directive.

Moving that directive to the bottom without location fixes post moving, but it also ends up processing a bunch of non-stock PHP scripts we have in subdirectories of root. Why is that post moving (incidentally, post to new thread works, but post to established thread does not) appears to be accessing a script outside of /?

In short, I need a solution for both issues, because both are basically deal-breakers for my site at this point.

Yes, this is a problem. vBSEO redirects to the main page on scripts that it doesn't know on the entire site when you move it out of the location directive.

Does anybody know why moving it out of the location directive fixes the problem with moving posts?

nginx is gaining market share rapidly, having recently blown by lighttpd. Many large site owners are giving it their praises and eva2000 all but officially endorses it here on this thread: nginx - the raise of a new giant - vBulletin Community Forum

This is something you people should probably be supporting. Very few of your customers are likely to have nothing but vBulletin on their entire site, and many are and will be moving in this direction.

You should include the forums folder name in rewrite rule to avoid processing of other scripts, like:

Code:

if ($request_filename ~ "\.php$" ) {
rewrite ^/forums/(.*)$ /forums/vbseo.php last;
}

The site in question exists in the documentroot so that isn't an option, and that wouldn't work even if it was in /forums. It would simply redirect all php no matter where it is on the site to /forums, without a location directive.

The solution is to figure out why it works outside of the location directive, and solve that problem.

What is an example URL that is being redirected? Make sure that you replace /forums/ with / in case if you have it in root.

Here is a snippet from the file that nginx is including for this virtual host:

Code:

        # vbseo
        location /
        {
                index                           index.php index.html;
                rewrite ^/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /vbseo_sitemap/vbs$

                if (!-e $request_filename)
                {
                        rewrite ^/(.*)$ /vbseo.php last;
                }
        }
        if ($request_filename ~ "\.php$" )
        {
                rewrite ^(.*)$ /vbseo.php last;
        }

Example URL would be: www.example.com/somedir/example.php

The behavior is that any php file on the site that vBSEO does not recognize is redirected to the front page.

The issue only happens with php files in somefolders, not in forums folder itself? Please try this:

Code:

rewrite ^/([^/]*)$ /vbseo.php last;

This works:

Code:

        # vbseo
        location /
        {
                index                           index.php index.html;
                rewrite ^/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;

                if (!-e $request_filename)
                {
                        rewrite ^/(.*)$ /vbseo.php last;
                }
        }
        if ($request_filename ~ "\.php$" )
        {
                rewrite ^/([^/]*)$ /vbseo.php last;
        }

Thanks much!

Great! I'm glad we got it working
