Customized error pages for 500

Server NGINX
1

Hi, I am a newbie to nginx. I need to have a customized error pages for
the http response codes 50x. I am running on nginx with passenger and
ruby on rails. I have problem with nginx.conf. I am not able to get my
customized 500.html page when the http error code is 500. I have tried a
lot but none of them seemed to work or I ran into other issues. I have
pasted my nginx.conf below. This is what I have right now in my server
and is working fine. What exactly to be added to the conf file to make
it work. Can some one help me out. All the pages are ‘https’.

In the access log I can see the entries:

[20/Jul/2010:11:38:49 +0000] “GET / HTTP/1.1” 500 193 “-” "Mozilla/5.0
(X11; U; Linux i686; en-US; rv:1.9.2.6)

But I am not bale to see the customized 500 page. I can see the nginx
500 page.

Thanks in advance. It will be very helpful to me.

BELOW IS THE NGINX CONF I HAVE RIGHT NOW.

Hi Igor S., Thank you for your reply. I made the change suggested
by you. But it is showing me the nginx 404 error page for every request.

Could you create a debug log:

of the requests ?

[snip]

     location = /500.html {

}

I would like to clarify what’s going on in these two lines of Igor’s
answer.

A. Note the “/500.html” part on the first line. That is not a variable
of any sort, but rather means that Nginx is expecting there to be a file
named 500.html in your root. In some examples you will see “/50x.html”
used instead. In that case, there must be a file that is literally named
“50x.html” in your root. (The “x” is not to be mistaken for a variable)

B. Note the “location = /500.html” block down below. There is nothing in
this block, but it is crucial that this block exists or your custom
error page will not be displayed.
