Salt Master Installation
- Swaminathan Mathivanan
We will perform these install processes on the Master server. The first step is to make sure our system packages are up to date

[root@host ~]#Now, we need to download the repository key for SaltStack and import it into our system.
[root@host ~]# wget -O- https://repo.saltstack.com/py3/ubuntu/18.04/amd64/latest/SALTSTACK-GPG-KEY.pub | sudo apt-key add -

[root@host ~]#Next, we can add the repository itself.
echo "deb http://repo.saltstack.com/py3/ubuntu/18.04/amd64/latest bionic main" | sudo tee /etc/apt/sources.list.d/saltstack.list
deb http://repo.saltstack.com/py3/ubuntu/18.04/amd64/latest bionic main
[root@host ~]#Now, we need to update our repo list so our available system packages are up to date.
Next, lets install SaltStack Master packages.
Salt Master Configuration
Using the nano or vim text editor, open the file /etc/salt/master.
Now, find the following line.
Once the value is located, uncomment it out and then specify the servers IP replacing the 0.0.0.0 IP address. In this example, we will use <xxx.xxx.xxx.xxx>. This will be the IP address from which we will control the minion servers.
Use :wq to save the file and exit. After editing, we should restart the service.
Next, we need to create a key that will be used by the minions to connect to the master nodes. We generated a unique key, so yours will be different.
You will want to make note of the master.pub key as we will need to add it into the configuration on the salt minion shortly.
Lastly, we will want to open the default ports in the firewall. By default, Salt uses ports 4505 and 4506.
