Error with rabbit-mq server

问题

I am trying to setup OpenStack on Ubuntu 12.04 using devstack. Now, the error I am getting is:

Setting up rabbitmq-server (2.7.1-0ubuntu4) ...
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
invoke-rc.d: initscript rabbitmq-server, action "start" failed.
dpkg: error processing rabbitmq-server (--configure):
 subprocess installed post-installation script returned error exit status 1
No apport report written because MaxReports is reached already
                                                              Errors were encountered while processing:
 rabbitmq-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
++ err_trap
++ local r=100
++ set +o xtrace
stack.sh failed

Any idea why am I getting this error?

回答1:

I had this issue twice, when either hostname or ip address in the hosts file didn't match. Therefore, check that you provide the correct ip address and hostname in the /etc/hosts file

Run sudo cat /etc/hostname to see your hostname

Output:

yoursite

Run sudo nano /etc/hosts

File contains:

127.0.0.1 yoursite

As you see from cat /etc/hostname, hostname is the same as in the /etc/hosts:

Run sudo rabbitmq-server start to start the rabbitmq-server

回答2:

Try deleting the folder /var/lib/rabbitmq and re-running ./stack.sh

If that doesn't work either, run the following after stach.sh fails:

chown -R rabbitmq:rabbitmq /var/lib/rabbitmq chown -R rabbitmq:rabbitmq /var/log/rabbitmq

service rabbitmq-server restart

and check the status of rabbitmq using "rabbitmqctl status"

Similar thing happen to me. Rabbit depends on being able to resolve a hostname, run this:

echo "127.0.0.1 $(hostname -s)" | sudo tee -a /etc/hosts

回答4:

This way works for me. First go to

sudo vim /etc/hosts

and set

127.0.0.1 <hostname>

then open firewall

sudo rabbitmq-plugins enable rabbitmq_management
sudo service rabbitmq-server restart

回答5:

For a clean environment, this will not happen. You must run devstack for several times, and one of them failed but you didn't get it cleaned.

run command pf -ef | grep rabbitmq, kill all rabbitmq processes. then it would be fine to run ./stack.sh

it is highly recommended to run ./unstack.sh && ./clean.sh before ./stack.sh

回答6:

Just to be sure, take a look to your local network

ip add

If there's no lo network, then you should enable it:

ifconfig lo up

Then restart the server again and let's see if it works again now

systemctl start rabbitmq-server
