-----------------SALT STACK---------

it is a configuration management tools

Python based, open source remote execution tool

remote execution means run commands on various machines in parallel with flexible targeting system

It estalishes the client server model quickly,easily and securely with in a given policy

--------SALT STACK Components-----------

Master

Minion --Client (OS (Redhat,Ubuntu)

Grains--Static information about minion (OS,memory,serial number etc)

Execution Modules--Adhoc commands executed from the command line to one or more target minions

-----Comparison

Scalability- Puppet,SaltStack,Ansible,Chef these are highly scaleable

Easeof setup--Puppet,SaltStack,Chef(Master and Agent Component) but in ansible it is on Master-Node

Availbility:- Puppet( it has multi master archietcure)

SaltStack( it has multimaster)

Ansible- it runs with a single active node called Primary instance, if primary instance is down then there

is Secondary instance to take its place

Chef:- Primary and Backup Server

Management:- Puppet:- Puppet DSL

SaltStack- Easy to learn

Ansible- Yaml syntax to learn Ansible

Chef:- Little diffcult as compare to other CMS

InterOperatability:-

Puppet:-Linux,Windows

SaltStack:- Master will run on the Linux but client can be windows/Linux

Ansible:- Supports windows but Ansible server has to be linux

Chef:- Primary server will be Linux and Client can be windows.

Configuration Language:-

Puppet:- DSL

SaltStack:- YAML

Ansile:- YAML

Chef:- DSL(Ruby)

Highest Score is given to Ansible

Install Salt Stack

Master:-

apt install python-pip

pip install salt

To Verify

salt --version

Minion:-

apt install python-pip

pip install salt

salt --version

write following code in /etc/salt/minion file

master: <<IP>>

id: min1

-----On Master machine

To run master component

salt-master -d

salt-master -l debug

Create a new window to run salt stack adhoc commands

salt-key -L # this is will show the id of minion under unaccepted key

salt-key -a min1 # to accept the key

salt 'min*' test.ping

salt 'min*' cmd.run 'pwd'

salt 'min*' file.touch '/tmp/1.txt'

salt 'min*' file.write '/tmp/1.txt' 'salt stack'

salt 'min1' grains.items

---On Minion

salt-minion -l debug
