Steps to install Ansible

• For example, take three servers (1-Ansiblemaster, 2-Nodes)

• Ansible as a means of managing our various servers, we need to install the Ansible software on at least one machine.

Ansible Installation on a CentOS/RedHat Server

Updating the machine.

#yum update

After updating the server with the above command, install the required packages

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Installing Ansible on CentOS.

#yum install -y ansible

Verify Ansible Installation.

# ansible --version

Ansible Installation on Ubuntu Server

Update Server.

#apt update

After updating the server with the above command, install the required packages.

# apt install -y software-properties-common

Create a repository.

#sudo apt-add-repository ppa:ansible/ansible

Install Ansible on Ubuntu Server.

#apt install -y ansible

Verify Ansible installation.

# ansible --version

Ansible Configuration and Host Inventory

Configuration file default location:

#vi /etc/ansible/ansible.cfg

#cp /etc/ansible/ansible.cfg   ~/

#vi ansible.cfg

After this need to enable some configurations in “#vi ansible.cfg”.

   inventory =/root/hosts/

   library =/usr/share/my_modules/

   module_utils =/usr/share/my_module_utils/

   remote_tmp =~/.ansible/tmp

   local tmp = ~/.ansible/tmp

   plugin_filters_cfg =/etc/ansible/plugin_filters.yml

   forks =5

   poll_interval =15

   sudo_user =root

   transport =smart

   remote_port = 22

   module_lang =C

   module_set_locale=False

   deprecation_warnings=False

Host file default location:

#vi /etc/ansible/hosts

#cp /etc/ansible/hosts  ~/

After changing the path of the Host and ansible.cfg files, first add the remote server IPs in the host inventory file and save the file.

#vi hosts

To check the connection is held or not in master. We can check with this command.

#ansible all –list-hosts  --> to see all connected nodes lists

Get all node details.

#ansible all –m ping

#ansible all –m setup

See if the selected node is connected.

#ansible ubnt –m ping
