Unsolved Salt Minion Problems
-
Here is the error message on the Salt Master's minion process:
Jan 31 20:32:37 salt salt-minion[901]: [ERROR ] The Salt Master has cached the public key for this node, this salt minion will wait for 10 seconds before attempting to re-authenticate -

That happens to all minions when they are waiting for the master to approve their key.

Yeah, the master didn't have an /etc/hosts entry so it was pointing itself to a different Salt Master. So that was awfully confusing.

Ok, so after fixing the hostname on the master, fixing the /etc/hosts file and then checking the errors, we find that that weird ip local address there is NOT from the Minion, but from the Master itself. So the Minion has never checked in at all.

Here is the current error on the minion. I'm guessing we have the same issue:

Here are some issues in the /etc/hosts file that will definitely cause things to fail:
192.168.1.97 192.168.1.94 salt 192.128.1.94 salt -
All this because you use another DNS that's not part of the project and it has overlapping details for other testers/production. lol

No, you would need this to be correct either way.
-
@scottalanmiller check what does salt have as the minion_id as well, it is in /etc/salt/minion_id
-
Also found the /etc/hosts file had a full double copy of itself in the same file. No idea how that got there.
-
Salt Master will not allow me to delete the keys that are in there. I did a delete all and it said that it was, but it failed.
-
okay. what do i need to do to fix it? sorry for the headache guys
-
well it looks like Scott fixed most of the problems. ( ish ) I just logged on to the server and all the things he pointed out as wrong, arent there anymore

I'm sorry - correct what either way?
If he had no DNS entry for salt, sure it would fail and he would be told to put entries in /etc/hosts but since there was a working salt server in DNS, things appear to work, but really aren't going where expected...
So having an over lapping lab just made the situation harder - ultimately learning more I guess.

Don't be - this is learning, sometimes you break things. Sometimes you don't. Scott digging into what you were doing exactly can be helpful in making guides that help future people learn with a little less pain.
@scottalanmiller can you pull a log of all of the commands he ran and perhaps find things like how the hosts file was completely doubled?

No really, it doesn't appear to work any more than if there is no entry at all.

My guess there is "vi mishap".
-
@scottalanmiller id agree with that, but inly because i thought i was doing one thing. While doing something completely different..
-
vi is a killer, one wrong key press and anything might happen.
