# Ansible-Master and target node configuration on AWS cloud using ssh-key Authentication
- About set-up:
I have installed ansible on the top of AWS cloud EC2 ,Setup is like take Three EC2 amazon linux instance, One of these make Master node(Ansible-master) and other remaining Two make Target node
(Ansible-node-1,Ansible-node-2).
## On three(master and target) instances Following set-up do as it is:
### Step-1: [Create new user i created "psadmin" general user for master node & set password]
Command for create new user:
useradd psadmin
Command for Set password to user:
passwd psadmin
### Step-2: [Give Sudo power to general user "psadmin"]
vi /etc/sudoers
### Step-3: [Allow Authentication in sshd config file]
vi /etc/ssh/sshd_config
### Step-4: [Restart sshd service]
systemctl restart sshd
- NOTE: for Target-node 1 & 2 i use general user is "pratik" after created user above four steps do as it is in each target nodes.
## On Ansible Master-Node:---
After do 1st four steps then create Key in general user in my case psadmin is general user of my Ansible master node
Go inside general user (psadmin) and create key for ssh Authentication:
ssh-keygen
Note: **Create ssh key at general user on which we want run ansible command.**
ssh-key created in **.ssh/** folder:
cd .ssh/
Show hidden file:
ls -l
After Key created then need to copy my "psadmin" key to host nodes , use follw command to copy key to Target node:
Format of ssh key copy to the target:
ssh-copy-id pratik@
Command for Copy ssh key:
ssh-copy-id [email protected]
After key add we also check bye using folloowing command:
ssh [email protected]
- NOTE: Do same Key-copy method to all target nodes .
**........Here our instances is successfully connected by "ssh"........**
## On master node: (Install Ansible on master node)
### Method 1st for installing Ansible :
Install ansible-core, but in this ansible do not provide config file, generally ansible-config file loaction = **/etc/ansible/ansible.cfg**
sudo yum install ansible-core -y
Command for check ansible version:
ansible --version
- We can create ansible config file manually:
NOTE: Fom General user we can't create config file so we need to go root or use sudo.
exit <<-- this helps to exit from General user
On master Root user:
Go inside **/etc/ansible** folder and create config file(ansible.cfg) use follw commands:
cd /etc/ansible
Create ansible.cfg file:
touch ansible.cfg
After we created ansible config file it is empty, So we pull file and copy in it for this use following command:
ansible-config init
Copy to destination **/etc/ansible/ansible.cfg**:
ansible-config init --disabled > /etc/ansible/ansible.cfg
- NOTE:
**If Amazon linux 2 ami use then use following command for download Ansible (/etc/ansible/ansible.cfg this config file provide).**
sudo amazon-linux-extras install ansible2
### Method 2nd for installing Ansible with download extra package for yum:
sudo yum update -y
sudo amazon-linux-extras install epel -y
sudo yum install ansible -y
Command for check ansible version and /etc/ansible/ansible.cfg location:
ansible --version
**In this way we give pre-created ansible config file**
### ansible.cfg file Settings:
In Ansible config file we do following changes:
Command for open ansible.cfg
vi /etc/ansible/ansible.cfg
**1st In this file we Add privilege escalation this give become method:**
**2nd In this file we also uncomment ansible Inventory (remove semi colon):**
**3rd Making host_key_checking is False:** (This is because while connecting to target by ssh the target node password ask, So deactive Host_key_checking)
Now ansible config file set-up:
Create ansible inventory, Location is **/etc/ansible/host**:
vi /etc/ansible/host
On "psadmin" general user (Master Node):
Command for checking all hosts are connected or not:
ansible all -m ping
Create & Run Ansible-Playbook:
vi web.yml
Command for Run ansible-playbook:
ansible-playbook web.yml
Check on target node httpd install or not:
rpm -q httpd
