Problems with CentOs 7 and MM 0.9.52

[danilo.souza]

Hi guys,

I used to run standalone MM 0.9.50 with CentOS 7, perfectly. Last week I updated MM to 0.9.52 with the help of @lmori and the proccess was completed with success. See ( https://live.paloaltonetworks.com/t5/MineMeld-Discussions/Updating-MineMeld-from-0-9-50-to-the-lates... ).

However since the upload my MM doesn't work the same way. On my Dashboard is visible that my miner works fine, more than 90K indicators, but almost none of them ara available, less than 1K in the outputs (see figure below).

If we detailed the proccess, we see that the status of many nodes is "stopped". The number of indicators forwarded by the miners is high.

The number of indicators forwarded by the aggregators is almost the same.

But the number of indicators available by the outputs is extrmely low.

Has anybody experienced something similar? How you dealed with the problem?

Best Regards.

Hi @lmori 

I followed the steps you indicated but I'm still getting an error:

Have you ever experienced something similar?

Did you delete the directory /opt/minemeld/prototypes before rerunning the playbook like Luigi (lmori) suggested?  That fixed my problem I was having with that issue.

Hi @StephenBradley 

for sure. When updating I delete 

/opt/minemeld/prototypes

/opt/minemeld/engine

/opt/minemeld/www

Unhapply it did not work for me.

[lmori]

The error means that the webui repo had changes in it. Are you sure you deleted the /opt/minemeld/www directory before rerunning the playbook?

Check here for detailed instructions: https://github.com/PaloAltoNetworks/minemeld-ansible/tree/develop#upgrade-minemeld

Hi @lmori 

I executed the procedure again. Now I got:

I double checked the folder "minemeld" before start and minemeld/prototypes, minemeld/www and minemeld/engine were deleted.

That is a different error. CentOS7 you are installing on has SELinux disabled. You can comment out the first task of this Ansible playbook here: https://github.com/PaloAltoNetworks/minemeld-ansible/blob/master/roles/minemeld/tasks/CentOS-7-post....

Hi @lmori 

I proceeded the same way. I commented the lines related to opening ports at the firewall. Now I got 0 errors.

However, I'm not able to login at MM WEGUI, and the status shows a fatal "Error to Engine":

I got in minemeld/log/minemeld-engine.log the following:

ERROR: Invalid config /opt/minemeld/local/config/committed-config.yml: Unknown node class youtubeminer.PlaylistMiner

How do I able an extension, since I'm not able to login.

Hi @lmori 

I removed MM from my server and started the installation from zero. I still got the "Fatal Error" for the engine when checking the status, and in my "minemeld-engine.log" I have:

I can confirm that I don't have " /var/run/redis/redis.sock".

In my MM WEBGUI I got "timeout" when trying to login.

Right now, I'm unable to use Minemeld.

Hi @lmori ,

the health of the system shows that the process "gunicorn" is probably in problem.

Hi @lmori ,

could you explain me what the status "BACKOFF" means for "minemeld-web":

Best regards

Thank you

I am still getting this error when following the directions on github.

Hi @StephenBradley 

You can comment the next four tasks

#- name: open https port
#  command: firewall-cmd --zone=public --add-service=https
#- name: open http port
#  command: firewall-cmd --zone=public --add-service=http
#- name: open https port (permanent)
#  command: firewall-cmd --zone=public --permanent --add-service=https
#- name: open http port (permanent)
#  command: firewall-cmd --zone=public --permanent --add-service=http

This will allow you to complete the installation. Even executing this procedures, my MM is not working.
