[ckan-dev] Apache problem (98)Address already in use when testing CKAN2.2 in docker

Thu Jan 30 17:18:54 UTC 2014

I'm wondering if someone with more knowledge of Apache might be able to
help.

I have been testing CKAN setups using docker, as per
https://github.com/kindly/ckan_dockered

This particular set-up was for version 2.1 and it has been working fine
running within a docker container.

Today, I wanted to test aspects of CKAN 2.2 and so tweaked the ckan_docker
repo locally to download *2.2-6_amd64.deb file from the build index here:
http://packaging.ckan.org/build/

The docker container builds fine and launches.  However, I'm getting a 502
gateway error when trying to access port 5000.  Any attempt to restart the
apache2 service fails with:

[Thu Jan 30 16:57:21 2014] [warn] NameVirtualHost *:8800 has no VirtualHosts

(98)Address already in use: make_sock: could not bind to address
0.0.0.0:8800

no listening sockets available, shutting down

Unable to open logs

Action 'start' failed.

The Apache error log may have more information.

Obviously my old container was shut down, so there were no obvious conflicts
in terms of port usage between containers.

I tried rebooting the EC2 instance . which didn't resolve things.

I also stopped and restarted on another instance . which also didn't make a
difference.

I am able to bring up the old container running 2.1 and point to the
<ip_address>:5000 fine.

I came across this possible resolution to '(98) Address already in use'
problem here: http://ubuntuforums.org/showthread.php?t=1636667

It suggests that that root of the problem is with a pass-phrase associated
with an SSL key which can cause Apache to crash.  While I do use one when
attaching to an EC2 using Putty, I can't believe that could be the source of
the problem ... or could it?

Thanks for any assistance you can offer.
