Can anyone help troubleshoot Datastax Opscenter installation? Its a new install on clean Ubuntu 14 server. Using apt-get to install, no issues, /var/log/opscenter is empty, but getting the following after tring to start the service, and it doesn't run:
root#unigmadevdse3:/var# service opscenterd start
root#unigmadevdse3:/var# service opscenterd status
* could not access pidfile for Cassandra cluster manager opscenterd root#unigmadevdse3:/var#
What is the version of OpsCenter that you are trying to install? Could you check the ownership/permissions of /var/run/opscenter? Also, can you please check disk space on /var? Try using su to switch to the opscenter user and try $ touch /var/run/opscenter/opscenter.pid. Be sure to remove it after.

I am trying to run rabbitmq server on my mac and i keep getting this error:
Starting broker...Logger - error: {removed_failing_handler,rabbit_log}
BOOT FAILED
I have tried reinstalling it several times and even logged into local host but see the same error.
Managed to fix it. Ran these commands to fully uninstall RabbitMQ (vhosts, users too).
sudo apt-get remove --auto-remove rabbitmq-server
sudo apt-get purge --auto-remove rabbitmq-server
Then after I reinstalled everything worked.
Another possibility is that you are running it on Big Sur- it keeps on giving errors to me that I didn't get previously.
Try pip3 uninstall rabbitmq-server then pip3 install rabbitmq server- that worked for me.
I newly installed Ubuntu 19.10, and installed redis with sudo apt install redis-server(5.0.5).
And started sudo systemctl start redis.
Executed redis-cli, then I got Could not connect to Redis at 127.0.0.1:6379: Y
The last 1 charactor (Y in this case) is different each time.
I just installed with using apt and didn't change any configs.
Is there any bugs or something I missed? please help me.
I tried to install from source code (5.0.7).
It works.
I have installed the Hortonworks sandbox HDP 2.6.5 (docker install).
After having many issues with Ambari "HeartBeat lost" I decided to upgrade Ambari to the latest version, so I cleanly uninstall ambari and then install 2.7.3 following the instructions from:
https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.7.3
After a long process I managed to complete the installation and start both services successfully: "ambari-server" and "ambari-agent"
Now I am stuck on the install wizard in the fisrt step without getting any error
or any progress. That is, after hitting "Next" it never gets to step 2. (see picture)
screenshot showing the issue
Things done so far to try to work this around:
restarting services (several times)
ambari-server upgrade (once more)
trying with chrome and IE
looking at the log files of ambari-server and ambari-agent
...but without success.
Has anybody come across the same issue?
Any clues?
Thanks for your help!
I have faced the same issue and I have activated the stack as shown below:
sudo sed -i 's|<active>false</active>|<active>true</active>|g' /var/lib/ambari-server/resources/stacks/HDP/2.6/metainfo.xml
sudo sed -i 's|<active>false</active>|<active>true</active>|g' /var/lib/ambari-server/resources/stacks/HDP/2.4/metainfo.xml
cat /var/lib/ambari-server/resources/stacks/HDP/2.6/metainfo.xml
cat /var/lib/ambari-server/resources/stacks/HDP/2.4/metainfo.xml
then I restarted the ambari-server and then it worked.
you have broken stacks for HDP. make sure you fresh build ambari 2.7.3 from source
https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.7.3
https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Development
copy folder and contents inside HDP stacks
/root/ambari-release-2.7.3/ambari-server/src/main/resources/stacks/HDP
ambari-release-2.7.3 is folder result build from source
paste to broken ambari-server
/var/lib/ambari-server/src/main/resources/stacks/
restart ambari server
I am running RabbitMQ on Ubuntu 16.04 under the Windows 10 "windows on linux" installation.
I cannot connect using rabbitmqctl. I used su to run as root and also tried to run it under my username with sudo, but everytime I run the command I get:
Diagnostic log
attempted to contact: ['rabbit#SJDEV-JWRIGHT3']
rabbit#SJDEV-JWRIGHT3:
* connected to epmd (port 4369) on SJDEV-JWRIGHT3
* epmd reports node 'rabbit' running on port 25672
* TCP connection succeeded but Erlang distribution failed
* suggestion: hostname mismatch?
* suggestion: is the cookie set correctly?
* suggestion: is the Erlang distribution using TLS?
current node details:
- node name: 'rabbitmq-cli-133#SJDEV-JWRIGHT3'
- home dir: /var/lib/rabbitmq
- cookie hash: iLmkDqwKzDZPxk8ynhqsVw==
I have uninstall and re-installed both Erlang and RabbitMQ. I changed the host names as suggested by someone else, and I still cannot figure out this problem.
I have rebooted the system, and when I tried to run rabbitmq-server restart and got:
ERROR: node with name "rabbit" already running on "SJDEV-[NODE]"
I am new to linux and have been digging in to this for a week and hit my breaking point.
Okay I found out the problem in a round about way. I am running this version of Ubuntu on the Windows Subsystem for Linux application on my windows 10 machine. My windows machine is already running rabbitmq and it happens to be on the same node as the node that I was trying to access using the rabbitmqctl. So there must be a correlation between the Ubuntu and windows system that shows rabbitmq already running. I may try this on a VM and see if I can get a clean break and try again.
Thanks.
I had this issue today.
My config is below:
Have a rabbitmq-server on Windows 10 OS
Have a rabbitmq-server on Ubuntu which was installed on Windows 10 OS (Ubuntu 18.04 app from Windows store)
Now below error makes sense:
ERROR: node with name "rabbit" already running on "MyComputerNamehere"
Another hint was Windows OS firewall has allowed both of them, in other words, they are running on same computer with name (ex: MyComputerNamehere).
Though I know the issue, I didn't fix it by removing rabbitmq-server from Windows 10, as I wanted Windows 10 rabbitmq-server, so gave up on Ubuntu on Windows 10.
Hope this explanation helps someone.
I'm installing new service in ambari managed cluster. my connection to hortonwork's repo seems too bad, it took lots of time to install ambari-server and ambari-agent it self (onece i almost thought it was dead).
the problem is that when i'm installing new service (e.g zeppelin, it also requires install other dependencies), the progress bar get stuck at 26% percent. it confused me if the installation get stucked or it's just too slow.
the command
ps -ef|grep apt
shows the the install is still there. only can't track the progress via /var/log/apt/term.log like normal apt-get installation (it shows the download progress).
the command shows the apt-get comes with an "-q" options which prevent me from tracking the log file.
so my question is that is there any place i can change the default behavior?
The -q option is added to "apt-get" command based on log level of ambari-agent. I.e. if log level for ambari-agent is set to DEBUG then apt-get without -q option is executed.
You can edit /etc/ambari-agent/conf/logging.conf, in [logger_root] section comment default line level=WARNING and add level=DEBUG. Then retstart ambari-agent. Now if you install any service them apt-get without -q will be executed.
Note:
If /etc/ambari-agent/conf/logging.conf does not exist then copy it from /etc/ambari-agent/conf/logging.conf.sample
Ambari agent specific changed need to be done on all cluster node
