Ansible – Install

A simple example of installing Ansible and adding a host.

Install Ansible:

RedHat systems:

yum install ansible

Deb systems:

apt install ansible

Generate an SSH key if it is not on the instance with Ansible:

ssh-keygen -t rsa

Add the public key to the host, which we will manage:

ssh-copy-id [email protected]

Add the host to the list:

vim /etc/ansible/hosts

And insert the following into it:

192.168.1.101 ansible_ssh_user=root

You can specify both an IP address and a DNS name.
root – the user on the remote machine that is used when connecting

Check the connection:

ansible -m ping all

192.168.1.101 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

all – run on all hosts specified in the file “/etc/ansible/hosts“

You can group hosts. For example, create a group “web” for our host:

[web]
192.168.1.101 ansible_ssh_user=root

Now you can call by group name:

ansible -m ping web
