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'm dealing with a problem related to sqlite, as shown below:

Do you have any idea why I'm getting it? How do I fix/workaround it?

While that is a good tip I am not an Ansible/Git expert and have no idea where the file is to even comment them out.  If there was anyway I could use Ubuntu I'd drop CentOS in a heartbeat because it just doesn't work.

Thank you

I found the place to comment out the firewall stuff and Minemeld installs and starts now but now I'm getting a bad gateway error for almost every command I try to click on in the GUI.

Hi @StephenBradley 

That's what I said in previous posts. I already asked @lmori , but I got no answer.

Please read this post https://live.paloaltonetworks.com/t5/MineMeld-Discussions/Problems-with-CentOs-7-and-MM-0-9-52/m-p/2...

That's where I'm stucked, and probably you too.

No, mine started up and I have the login screen.  As soon as I enter admin/minemeld it throws the red block error bad gateway up in the right hand corner.

Ubuntu looks better and better for this.

Hi @StephenBradley 

I'm getting the same error - Bad Gateway. The link that I told you to read is related to it. Those lines are from the "minemeld-web.log" file.

Hi @StephenBradley 

I think I found the way to resolve the problem. Execute the folowing:

ln -s /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/lib-dynload/

Let me know if it works.

Hi @lmori 

How can I work around a problem related with "Error reading last checkpoint"? I'm getting the following in my "minemeld-engine.log"

My MM engine is restarting continously. I even changed the config to the default one (few nodes - spamhaus etc.) but I'm getting the same behaviour. Should I delete all ".chpk" files in "/opt/minemeld/local/data/" and restart the engine?

That did it!!

Working on comparing it to my 0.9.52 Ubuntu version now which I am using a temp production.

Thank you

Hi guys

this problem started when I was trying to update to 0.9.52 version, but took so long that I finally completed the process with 0.9.60 version. To solve the problem with 0.9.60 version, you should execute the folowing, after the known basic steps:

ln -s /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/lib-dynload/

This solve the problem of getting "Bad Gateway" message in MM WebGUI.

Best regards
