FCGI Error when dispatching

Added by Tomasz Jurczyk about 9 years ago

Hi all,

I'm trying to host Redmine using Apache and FastCGI on my CentOS. Through WEBrick everything works perfectly. I followed this tutorial: http://www.redmine.org/projects/redmine/wiki/HowTo_configure_Apache_to_run_Redmine

When I'm trying to run public/dispatch.fcgi, this is what I got:

-bash-4.1$ ./public/dispatch.fcgi
Your FCGI gem does not contain the FCGI shared library, running pure ruby instead
/var/www/html/redmine/vendor/bundle/ruby/1.8/gems/fcgi-0.9.2.1/lib/fcgi.rb:118:in `accept': Socket operation on non-socket (Errno::ENOTSOCK)
    from /var/www/html/redmine/vendor/bundle/ruby/1.8/gems/fcgi-0.9.2.1/lib/fcgi.rb:118:in `session'

    from /var/www/html/redmine/vendor/bundle/ruby/1.8/gems/fcgi-0.9.2.1/lib/fcgi.rb:41:in `each'

    from ./public/dispatch.fcgi:20
-bash-4.1$

This is my 'about':

-bash-4.1$ RAILS_ENV=production ruby script/about
Your FCGI gem does not contain the FCGI shared library, running pure ruby instead

Redmine plugins:

I found similar problem here (from year ago): http://www.redmine.org/boards/2/topics/41999?r=42004
but it was never answered (rather than suggested to use Passenger). Any help will be greatly appreciated.

Thanks!
Tomasz

Hi,
I think the message

Your FCGI gem does not contain the FCGI shared library, running pure ruby instead

means it could not find fcgi.so.

Hi Leonel,

thanks for your post. Yes, I've been trying to find the solution to this for the last 3 hours. Problem seems to be here:

[root@nlp lib]# pwd
/usr/lib/ruby/gems/1.8/gems/fcgi-0.9.2.1/lib
[root@nlp lib]# ls -l
total 60
-rw-r--r--. 1 root root 14721 May  8 12:55 fcgi.rb
-rwxr-xr-x. 1 root root 44359 May  7 23:00 fcgi.so

One of the first lines in fcgi.rb:

begin
  raise LoadError if ENV["USE_PURE_RUBY_FCGI"]
  require "fcgi.so" 
#rescue LoadError # Load the pure ruby version instead
  # At this point we do have STDERR so put it to some good use
  $stderr.puts "Your FCGI gem does not contain the FCGI shared library, running pure ruby instead"

Even there is

require "fcgi.so"

it seems to not working properly. I tried to change it to

require "fcgi"

, but it didn't work either.

I tried with passenger without a success. There is some bug in it and it has been reported recently on the passenger issue tracker (~2 weeks ago). This bug concerns passenger specifically on CentOS and is caused partially because of SELinux.

I finally got it working!
I'm not 100% sure what was the reason (because I tried many possible hacks and solutions), but I mainly added this (and I think this is the reason it started working) in Gemfile.local:

gem "fcgi"

and called 'bundle install'.

Also, I needed to add these two lines in 'public/dispatch.fcgi'

require 'rubygems'
require 'fcgi'
