Fedora Salt Master - New installation

DustinB3403

I'm playing with Salt (and ansible) and both seem like viable options for managing Mac OS devices, however with salt, supposedly the easier of the systems to start learning and using I'm having an issue.

Fedora Server 30

yum install salt-master I tried DNF and it failed.

systemctl enable salt-master.service
systemctl start salt-master.service

Loaded and active

As I don't have DNS setup at the moment I changed the /etc/salt/master to list the IP as the master, rather than salt

However when I configure an Mac OS laptop with the salt minion and go and check the salt-master I have this

salt-master --log-level=debug
/usr/lib/python2.7/site-packages/salt/scripts.py:102: DeprecationWarning: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.  Salt will drop support for Python 2.7 in the Sodium release or later.

What am I doing wrong here?

DustinB3403

The master address was changed on the slave, and not the master.

The slave can ping the master and the master can ping the slave.

User error, because yum redirects to dnf anyway.

DustinB3403

@JaredBusch okay. . . maybe it just errorr'd out initially.

In any case, the service is running and saying it can't use the default ports.

Is there something else I'm missing here?

Turn off SELinux

JaredBusch

If that fixes it, then you need to look at what you need to allow.

Turn off SELinux

~~Just disabled selinux and restarted the services, same error message.~~

Something is already bound to that port from the looks of it. Have you tried doing a netstat tulp to see what's listening?

ooks of it. Have you tried doing a netstat tulp to see what's listening?

I disabled selinux, but didn't reboot the host. Restarting now to see if that changes it.

Nothing should be using the port at all by default, this is the only service installed.

scottalanmiller

Do a...

netstat -tulpn

scottalanmiller

If that isn't installed do...

dnf install net-tools -y

There you go, a Python process is using those ports.

That's the salt-master. .

So the Salt-Master is running.

DustinB3403

@coliver yea, it's running, but it can't use the ports it automatically setup to run. .

Which is why I'm asking if I've missed something. .

We just determined that it is using those ports.
