Thank you for your help!

I had looked in ‘/usr/lib/systemd/system/mysql.service’ and found an interesting thing at the bottom:

# Unsafe for PXC

# mysqld\_safe handles this too.

Restart=always

I don’t know why it is enabled in PXC installation if it is unsafe but I commented it:  
#Restart=always

After that I rebooted my machines. nothing changed, yes. But now I can easily kill my mysql process if something happens and start it again! So, now I don’t need to restart machines at all. If something happens (stuck in ‘activating’ state) I can stop/kill mysql and start it again!

Sincerely,  
Alexandr
