Part 1: Setup and Configure Basic Environment

The following nodes will need to be created: two Salt masters, two SaltStack Enterprise Servers (RaaS heads), a Redis Server, and a PostgreSQL Server.

1. SSE-Master01
2. SSE-Master02
3. SSE-PGSQL01
4. SSE-RAAS01
5. SSE-RAAS02
6. SSE-Redis01

Step 1: Install and Configure the Salt Master on SSE-Master01 and SSE-Master02

a. On both SSE-Master01 and SSE-Master02, import the SaltStack GPG Key:

rpm --import https://repo.saltstack.com/yum/redhat/7/x86_64/archive/2018.3.4/SALTSTACK-GPG-KEY.pub

b. On both SSE-Master01 and SSE-Master02, create the SaltStack repo file:

Create: /etc/yum.repos.d/salt-2018.3.4.repo
- - - - - - - - - - - - - - - - - - - - -
[saltstack-repo]
name=SaltStack repo for RHEL/CentOS $releasever
baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/archive/2018.3.4
enabled=1
gpgcheck=1
gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/archive/2018.3.4/SALTSTACK-GPG-KEY.pub

c. On both SSE-Master01 and SSE-Master02, clean the yum expire-cache:

yum clean expire-cache

d. On both SSE-Master01 and SSE-Master02, install the Salt Master:

yum install salt-master

e. Enable and Start the Salt Master on SSE-Master01:

systemctl enable salt-master
systemctl start salt-master

f. Retrieve the Salt Keypair Generated by Starting the Salt Master on SSE-Master01

cd /etc/salt/pki/master/

g. Enable and Start the Salt Master on SSE-Master02:

systemctl enable salt-master
systemctl start salt-master

Step 2: Install and Configure the Salt Minion on SSE-Master01 and SSE-Master02

a. On both SSE-Master01 and SSE-Master02, install the Salt Minion:

yum install salt-minion

b. Set the Minion ID on SSE-Master01:

echo SSE-Master01 > /etc/salt/minion_id

c. Set the Minion ID on SSE-Master02:

echo SSE-Master02 > /etc/salt/minion_id

d. Set the Salt Master Configuration on both SSE-Master01 and SSE-Master02:

cat > /etc/salt/minion.d/masters.conf <<EOF
master:
  - SSE-Master01
  - SSE-Master02
EOF

e. Enable and Start the Salt Minion on SSE-Master01 and SSE-Master02:

systemctl enable salt-minion
systemctl start salt-minion

f. Accept the Salt Keys for Minions SSE-Master01 and SSE-Master02 from both Masters:

salt-key -ya SSE-Master01
salt-key -ya SSE-Master02

g. Verify that both minions are responding to both masters via test.ping:

salt 'SSE-Master*' test.ping

h. As an additional exercise, observe the message bus of both Salt masters while performing a test.ping.  Execute the following command from a separate terminal window for each master to observe Salt events in real time:

salt-run state.event pretty=True

Execute the following command from your original terminal window for each master. Note that each Salt Minion responds to the Salt Master that published the event:

salt 'SSE-Master*' test.ping

Step 3: Install and Configure the Salt Minion on SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01

a. On SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01, import the SaltStack GPG Key:

rpm --import https://repo.saltstack.com/yum/redhat/7/x86_64/archive/2018.3.4/SALTSTACK-GPG-KEY.pub

b. On SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01, create the SaltStack repo file:

Create: /etc/yum.repos.d/salt-2018.3.4.repo
- - - - - - - - - - - - - - - - - - - - -
[saltstack-repo]
name=SaltStack repo for RHEL/CentOS $releasever
baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/archive/2018.3.4
enabled=1
gpgcheck=1
gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/archive/2018.3.4/SALTSTACK-GPG-KEY.pub

c. On SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01, clean the yum expire-cache:

yum clean expire-cache

d. On SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01, install the Salt Minion:

yum install salt-minion

e. Set the Minion ID on SSE-PGSQL01:

echo SSE-PGSQL01 > /etc/salt/minion_id

f. Set the Minion ID on SSE-RAAS01:

echo SSE-RAAS01 > /etc/salt/minion_id

g. Set the Minion ID on SSE-RAAS02:

echo SSE-RAAS02 > /etc/salt/minion_id

h. Set the Minion ID on SSE-Redis01:

echo SSE-Redis01 > /etc/salt/minion_id

i. Set the Salt Master Configuration on SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01:

cat > /etc/salt/minion.d/masters.conf <<EOF
master:
  - SSE-Master01
  - SSE-Master02
EOF

j. Enable and Start the Salt Minion on SSE-PGSQL01, SSE-RAAS01, SSE-RAAS02, and SSE-Redis01:

systemctl enable salt-minion
systemctl start salt-minion

k. Accept the Salt Keys for Minions SSE-Master01 and SSE-Master02 from both Masters:

salt-key -ya SSE-PGSQL01
salt-key -ya SSE-RAAS01
salt-key -ya SSE-RAAS02
salt-key -ya SSE-Redis01

l. Validate that All Minions are Responding to both Masters:

salt \* test.ping

Step 4: Install SaltStack Enterprise

Using the instructions from https://enterprise.saltstack.com, download the SSE Installer and follow the Multi Node guide from the "Use the Installer" section in the documentation.
