0.2.25 node5.example.com
yum -y install ansible
useradd ansible
echo password | passwd --stdin ansible
echo "ansible ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/ansible
su - ansible; ssh-keygen
ssh-copy-id node1.example.com
ssh-copy-id node2.example.com
ssh-copy-id node3.example.com
ssh-copy-id node4.example.com

***Each manage node setup***
First, add an extra 2GB virtual harddisk to each control node 1,2,3. Then add an extra hard disk to control node 4. Do not add an extra hard disk to node 5. When you start up these machines the extra disks should be automatically located at /dev/sdb (or /dev/vdb depending on your hypervisor).
useradd ansible
echo password | passwd --stdin ansible
echo "ansible ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/ansible
Note python3 should be installed by default, however if it is not then on both the control node and managed nodes you can install it also set the default python3 if you are having trouble with python2
being the default.
yum -y install python3
alternatives --set python /usr/bin/python3
All machines need the repos available. You did this in RHSC
A To set up locally you just need to do the same for each machine. Attach the rhel8 iso as a disk to virtualbox, kvm or whatever hypervisor you are using (this will be /dev/sr0). Then inside the machine:
mount /dev/sr0 to /mnt
Then you will have all the files from the iso in /mnt.
mkdir /repo
cp -r /mnt /repo
vim /etc/yum.repos.d/base.repo
Inside this file:
[baseos]
name=baseos
baseurl=file:///repo/BaseOS
gpgcheck=0
Also the appstream
vim /etc/yum.repos.d/appstream.repo
Inside this file:
[appstream]
name=appstream
baseurl=file:///repo/AppStream
gpgcheck=0
Install and configure ansible
User bob has been created on your control node. Give him the appropriate permissions on the control node. Install the necessary packages to run ansible on the control node.
Create a configuration file /home/bob/ansible/ansible.cfg to meet the following requirements:
• The roles path should include /home/bob/ansible/roles, as well as any other path that may be required for the course of the sample exam.
• The inventory file path is /home/bob/ansible/inventory.
• Ansible should be able to manage 10 hosts at a single time.
• Ansible should connect to all managed nodes using the bob user.
Create an inventory file for the following five nodes:
nodel.example.com
node2.example.com
node3.example.com
node4.example.com
node5.example.com
Configure these nodes to be in an inventory file where node1 is a member of group dev. nodc2 is a member of group test, nodc3 is a member of group proxy, nodc4 and node 5 are members of group prod. Also, prod is a member of group webservers.
