Why I can't use rabbitmq.config? - rabbitmq

I don't see rabbitmq.config in /etc/rabbitmq so I download it from here
If I directly execute systemctl restart rabbitmq-server.service it can work
But when I modify ## {loopback_users, [<<"guest">>]}, to ## {loopback_users, []} it can't work, what happen? What should I do?
the error occur
$ systemctl restart rabbitmq-server.service
Job for rabbitmq-server.service failed because the control process exited with error code.
See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

Except i kill the pids again. I don't understand why this is happening.
I expect the devstack to install completely. It's just tiring
Try to reinstall apache2.
It worked for me.
sudo apt-get reinstall apache2

Has anyone else faced this? What am I doing wrong.
It is a permissions error. In the last line:
/usr/bin/env service myApp start
Try:
/usr/bin/env sudo service myApp start

httpd start fails and shows up error

While i try to install server through yum install httpd and later when i start service it shows up following error :
[root#localhost ~]# systemctl enable httpd.service
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
[root#localhost ~]# systemctl start httpd.service
Job for httpd.service failed. See 'systemctl status httpd.service' and 'journalctl -xn' for details.

Can any body please help on it??

Error with rabbit-mq server

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?
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
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
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
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
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
I had the same problem though my /etc/hosts and DNS were OK. I suspect that SystemV init script was started too early when the network was not ready yet. I rewrote the startup script to systemd on CentOS 7.8 and it seems to work well now.
