Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy and its is a configuration management and provisioning tool, similar to Chef or Puppet. Here I'll introduce a one step procedure to install Ansible in RHEL 7/CentOS 7
Login to your server as root and run the following command:
yum -y update; yum -y install vim; yum -y install wget; mkdir /tmp/ansible/; cd /tmp/ansible; wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm; sudo yum -y install epel-release-latest-7.noarch.rpm;
yum -y install ansible; ansible --version;
