SaltStack is a open source configuration management used remote execution tool. With the use of remote execution system administrators can execute the programs and command from the master system named as salt to the agent system named as minions.Lets start

Requirements:-

Controller Machine (Salt-Master) :-

ip : 10.0.0.209

Node (Minion):-

ip: 10.0.0.206
hostname: minion1

Step 1 : Installing Salt-Master on controller machine:

Install the latest salt-master on your controller machine using YUM.

# yum install salt-master -y

After the installation finishes, modify the configuration file as below:

# vi/etc/salt/master

Find the given line and replace :

# interface: 0.0.0.0

to

interface: 10.0.0.209

Find the given line and replace :

#hash_type: md5

to

hash_type: sha256

Then save and quit using :wq!

Start and enable the salt-master service

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

Step 2 :

Enable the default port of saltstack 4505-4506 in firewall.

# firewall-cmd --permanent --zone=public --add-port=4505-4506/tcp
# firewall-cmd –reload

Step 3 :
Install and configure the salt-minion on the nodes.

# yum install salt-minion

After the installation finishes, modify the configuration file as below:

# vi /etc/salt/minion

Find the given line and replace :

#master: salt

to

master: 10.0.0.209

Find the given line and replace :

#hash_type: md5

to

hash_type: sha256

Then save and quit using :wq!

Start and enable the salt-minion service

# systemctl start salt-minion.service
# systemctl enable salt-minion.service

Step 4 : Test the Saltstack working

From the SaltStack master server, input the following command to show all available agents:

# salt-key -L

If everything was successful, you will see the agent server “minion1” listed in the “Unaccepted Keys” segment.

Accepted Keys: 
Denied Keys: 
Unaccepted Keys: 
minion1 
Rejected Keys:

After it we need to accept “minion1” using this command:

# salt-key --accept=minion1

Step 5 : Test the Setup

# salt minion1 test.ping

The output show:

minion1: 
True 
Try the command also.

# salt minion1 cmd.run 'df -h'

Thankyou. Now you are successfully installed and configured saltstack
