Hello,

I am using ubuntu 13.04 with openstack grizzly version. my openstack was working fine and i was able to commnicate to my vm instances from external network and vice versa, but suddenly due to some issue i started facing problem. I am getting "[Errno 111] Connection refused" error, I have faced this same issue many times in past and i use to reinstall from scratch, but after sometime again i will end up in same problem. This happens every time not only for me all my peers also facing the same issue on their lab setup. This behavior make me think like after some time the database is getting corrupted or something similar to this . i would really appreciate if someone can help me to narrow down the root cause ?

Thanks in advance.

FYI, This happened when i was installing keystone on a fresh OS , This happens when the source file is not loaded or the parameters in source files are incorrect or has been changed on the OS.

My source file was having the following entries -:

export OS_TENANT_NAME=admin export OS_USERNAME=admin

Hello

I have received this error when I don't source my environment credentials. I hope you are not making the same mistake. If so,source your environment variables in .bashrc file.

This might be related to http_proxy being set in the environment. I have faced this a couple of times because of the http_proxy being set, after removing http_proxy from the environment system starts working fine. This happens for an environment where the you have a local network behind proxy and all the request to keystone for validation is sent to the proxy instead which fails, you may also want to add no proxy for localhost.

i use ntlmaps-0.9.9.0.1 for isa proxy authentication and i set

export http_proxy="http://127.0.0.1:5865"

and i also do

export http_proxy="http://127.0.0.1:5865" >> /etc/profile and

Actually i even tried un setting http_proxy variable but it didn't help.

Have you tried to do:

sudo service iptables stop on your server.

I've ever had this problem and I solved it when I modified my iptables

Hello, I have this problem right now (5 years later), I ran that command and it solved it temporarily just to be blocked again in like 30 minutes. How should I modify the iptables to prevent this again?

I had this issue and found that the problem was because neutron was not able to communicate with rabbitmq. To see if this is your problem you can try the following snippet of code:

Script started, file is typescript [ -r /etc/default/neutron-server ] && . /etc/default/neutron-server [ -r "$NEUTRON_PLUGIN_CONFIG" ] && CONF_ARG="--config-file $NEUTRON_PLUGIN_CONFIG" exec start-stop-daemon --start --chuid neutron --exec /usr/bin/neutron-server -- \ --config-file /etc/neutron/neutron.conf \ --log-file /var/log/neutron/server.log $CONF_ARG end script

(you can find this at the end of a file found in /etc/init/neutron-server.conf)

When I ran this it showed me errors I had in my config files and after I fixed them it showed the following: 2014-05-03 17:19:33.123 17996 ERROR neutron.openstack.common.rpc.common [-] AMQP server on 192.168.0.143:5672 is unreachable: Socket closed. Trying again in 1 seconds. 2014-05-03 17:19:37.136 17996 ERROR neutron.openstack.common.rpc.common [-] AMQP server on 192.168.0.143:5672 is unreachable: Socket closed. Trying again in 3 seconds. 2014-05-03 17:19:43.149 17996 ERROR neutron.openstack.common.rpc.common [-] AMQP server on 192.168.0.143:5672 is unreachable: Socket closed. Trying again in 5 seconds.

I then ran netstat to see what port rabbitmq had opened. Rabbitmq had opened the port, but tied it to "localhost" not my ip address, which I would have thought. So to fix neutron not being able to find rabbitmq. I changed the following lines in my config files:

rabbit_host = localhost

Then I changed my /etc/hosts file to reflect the following:

"my Ip address" localhost ------instead of the 127.0.0.1 localhost that was default in my file.

After I did all of the nuetron and nova now actually started talking to rabbitmq and I stopped getting the [Errno 111] ECONNREFUSED error. Hope this helps.
