How to find the cause of my CentOS 7 woes – networking and more won't start
I tried doing my usual yum updates and they failed with a “killed”. I then followed a series of steps to try to recover this. After I finally got yum happy, I rebooted the server, only to find it uncontactable.
So far I have managed to access the DO-Console, but even that appears to be behaving badly. What I’ve discovered so far is network and logind at least are failed. Apache and MariaDB appear fine – just none of it can be accessed because networking is down!
I have tried further reboots to no avail. Same problems. I tried starting network and it has been hung there for many minutes now.
