Issue Pretty bad problem: Server starts successfully and starts all services but stops them again.

[Fuchur]

Hello guys,

thank you for taking the time to have a look at this thread.
I have a big problem: My server is no longer responding to SSH (directly), webaccess or anything else.
I have a recovery system accessable by SSH where I can have a look at the logs and change files, but I can only run SSH comments int the recovery system, not the normal boot system like that.

I am pretty sure that I've got a configuration error or a write problem, but I am not sure how to go on from there.
It seems like the server starts up fine but then one process after another which just has been started stops again.

As you can see first there are some permission problems but I think they do not matter for this that much.
The more important stuff might be the firewall? But I am not sure.

As for now, the server ist starting all the more important services to show plesk and run websites/E-Mails and after that it just shuts them down a couple of seconds later.
Does anybody have a solution for this problem?

This is a Ubuntu 16.04 LTS 64bit + Plesk Onyx 17.8.11 recently updated to 18.0.31 vServer. I ran into mail problems when I tried to install a SSL certificate recently to the mail system and then it all went downhill. I think my configuration was no longer boot safe and when I restarted it the problem occured somehow.

I am pretty much stuck at the moment and can not get the server to do anything for now. Thank you very much for any help in advance.

Best regards

PS: had to shorten the log alot. Please the attached file for more.

Okay, I can run a .sh-file with a crontab/job as it seems. I tried to run plesk repair all -y but it did not work out. Same behaviour is invoked as in the system log above starting and closing everything. Anybody has any idea?
