My service got suspended due CMM updates

I am not sure what happened and I don't know what caused the problem. I wasn't aware of this until my service was supended and I couldn't access to my site (my site is a xenforo forum which is closed to guests).

---

VPS CentOS 6.6 here

Today I did (in this order):

• CMM update to newest branch by using following code (from stable .07):
  Spoiler

  Code:

  branchname=123.08centos7beta02
  wget -O /usr/local/src/${branchname}.zip https://github.com/centminmod/centminmod/archive/${branchname}.zip
  cd /usr/local/src
  unzip -o ${branchname}.zip
  rm -rf ${branchname}.zip
  rm -rf /usr/local/src/centmin-v1.2.3mod/
  mv centminmod-${branchname} centmin-v1.2.3mod
  cd centmin-v1.2.3mod
  chmod +x centmin.sh
  yum clean all
  ./centmin.sh

• I updated from MariaDB 5.5 to 10.x via centmin.sh menu
  
• I added php ssh2 extension by using these instructions.
• I updated to php 5.6.8 via centmin.sh menu

I am not sure what I did wrong and what I should do now.

"Never change a running system..."

 

No, do I need to do that and why and how?

Btw, I updated php 3-4 hours later. The high server load began earlier as it seems.

edit: restarted php-fpm now

edit2:


It seems fine now.

 

Of course there are restrictions, this is why I got banned. The cpu usage was way too much. Usually it is 0.00 by average, when I do some installations it gets a bit higher, like 0.50 but yesterday it went up to 8 and stayed for a long time above 4, which is a valid reason to suspend an account. I don't blame my VPS host, their policy is clear. The problem is from my end and I just don't know what happened. My webhost ist VPSDime.

I'll look into that, thanks.

Well I got suspended right after those installations. I didn't upgrade everything at once, there is like 1-2 hours between all of them.
So the time interval is like 6 hours.I upgraded everythig (within 1-2 hours) and went on idle. But it seems the server ran on high capacity for many hours and then they suspend me, which is fair of course. I just didn't realize the high cpu usage and why this happened.

And I forgot to mention, that I also installed 1 Xenforo add-on which is called bd Cache. So it might be that maybe.

 

Thanks. Everything is fine now. So you don't need to start troubleshooting or something like that.
And thanks for that linking.
I have now a lot of stuff for reading and for the future I know now that I need some monitoring.

 

Hey,

now I have a question. I followed your recommendation and I am monitoring my cpu load using htop.

When my forum was closed, I had a load average of 0.
For 5 months it was like this.

Now, yesterday after I opened my forum to the public, it jumped to 1.10 while using 40% of CPU%.

Is this a normal behaviour?

I must admit, sometimes I don't exit centmin.sh via option 23. Instead I just disconnect from the server.

And I invoke to centmin.sh always like this:

Code:

cd /usr/local/src/centmin-v1.2.3mod
./centmin.sh

 

Well, now I did, 3 times now, to be sure.
Still 39% usage for centmin.sh

Ah, ok. Just where did you explain how to kill the process? Sorry, I don't see it.

 

Thanks! That worked. And I learned 2 things.
Always exit properly and now I know how to kill processes.

What a coincidence, that guy from the other thread had the same issue. And I thought it might have to do with my forum.
