Install Ansible 2.5 on Debian 9 Stretch or Ubuntu 18.04 from source
Ansible is an open-source automation engine like Chef, Puppet, Salt, CFEngine,
It’s a very useful tool if you manage several servers, more than 50 for example.
Ansible is written in python and have a lots of advandages :
- Ansible is agentless (no agent needed on remote server, Ansible use SSH and current user ssh authorisation).
- You can install it and manage remote servers from your laptop, I prefer nonetheless to install it on a central management server.
- Ansible installation is minimal, compilation do not need a lot of dependencies.
- Ansible has the reputation to be easy to master (Ansible is design for DevOps ^^).
- A lot of Playbook are already available (a Playbook, is a template).
- Is not written on ruby like Puppet 🙂
Ansible installation not need a lot of dependencies, so I prefer to build Ansible package from source in order to have last version and last functionalities.
I – Install prerequisite
Ancible required few prerequisite build-essential, git and some python and openssl tools.
root@ansible:~# apt update
root@ansible:~# apt install make git make python-setuptools gcc python-dev libffi-dev libssl-dev python-packaging
II – Download Ansible source from Official GIT repository
root@ansible:~# cd /usr/local/src/
root@ansible:/usr/local/src# git clone git://github.com/ansible/ansible.git
root@ansible:/usr/local/src# cd ansible
III – List available Ansible version
root@ansible:/usr/local/src/ansible# git branch -a | grep stable
IV – Install Ansible from source
I choose the last stable version (Ansible 2.5 “Kashmir”).
Release note of Ansible 2.5 :
root@ansible:/usr/local/src/ansible# git checkout stable-2.5
root@ansible:/usr/local/src/ansible# source ./hacking/env-setup
root@ansible:/usr/local/src/ansible# make && make install
V – Test Ansible
You can test if the program work correctly, by calling him with the argument –version
admin_florian@ansible:~$ ansible --version
config file = None
configured module search path = [u'/home/florian/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/local/lib/python2.7/dist-packages/ansible-2.5.0-py2.7.egg/ansible
executable location = /usr/local/bin/ansible
python version = 2.7.14+ (default, Mar 13 2018, 15:23:44) [GCC 7.3.0]
You can now write your own playbook and appreciate this great and magical tools !!!
For security issue, I advise to not use the root account, or account named with a predictable name (example: admin/ansible/manager/etc...). For my part, I use my personal account and my personal ssh private key on my central management server.
