Ansible : UDMY -- 6. Ansible on Linux

 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Running Ansible as a Control host on Linux . 




Installing Ansible using APT which is built into the system 

$ ifconfig -a

apt is a command-line utility for installing, updating, removing, and otherwise

$ sudo apt-get update

$ sudo apt install ansible

$ which ansible

/usr/bin/ansible

$ ansible --version

Restored back the machine to its original state before installation -- to show the next method to install Ansible. 

*** Second type : Personal Packages Archive 

$ sudo apt-get update

  1. The sudo apt-get update command is used to download package information from all configured sources.
  2. The sources often defined in /etc/apt/sources.list file and other files located in /etc/apt/sources.list.d/ directory.
  3. So when you run update command, it downloads the package information from the Internet. It is useful to get info on an updated version of packages or their dependencies.

$ sudo apt-get install software-properties-common 

 Now we can add in the APT repository  

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

$ sudo apt-get update -- To get that information from that repository

and now 

$ sudo apt-get install ansible 

$ ansible --version

Restored back the machine to its original state before installation -- to show the next method to install Ansible. 

Installing Ansible using VirtualEnv and PIP .

$ sudo apt-get update 

And then we need to install dependencies while we are doing this .

$ sudo apt-get install python-minimal virtualenv python-dev build-essesntial

so we got the dependencies in place 

we will create a directory to store all of this 

$ mkdir ansible

$ cd ansible

 And we will create virtual environment and we will call it 

$ virtualenv venv27


And we will activate that virtual environment 

$ source venv27/bin/activate

$ which python

$ which pip

Now if you are going to install anything using PIP it is going to install into that virtual environment

$ pip install ansible


One of the advantages of PIP is that you have got a loads of control over PIP . 

Now we are going to  uninstall ansible

$ pip uninstall ansible

$ git  -- checking if git is installed -- we do not find it therefore we are installing it .

$ sudo apt install git

Now what we can do is install git again using PIP 

$  pip install git+https://github.com/ansible/ansible

 Now that process can take a while .

Lets see how we install Ansible on RHEL / CentOS - Lab Exercise

We are on the CentOS system

$ ifconfig -a

Installing Ansible but through  the creation of our own RPM . Ansible it is a RedHat Product one of the product that they recommend is to create your own RPM

first we are going to install our dependencies 

$ sudo yum install asciidoc python-jija2 PyYAML git python-setuptools rpm-build python2-devel

 I am just going to go to the /tmp directory and we are going to clone the current version of ansible 

$ git clone git://github.com/ansible/ansible.git 

We go into ansible directory that we just cloned. 

create the rpm -- 

$ make rpm

 It has build our rpm , lets have a look. Our rpm is installed in rpm-build 

$ ls rmp-build/

 Now we can install this 


 Now we need to install dependencies 


Now we can install our package

Ansible : UDMY -- 7. Validating Ansible Installation -- adhoc commands start - for loop to ssh key

Image
 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Here we will validate Ansible to check if it is working as expected . If you are using Ubuntu-c or configured your own Ansible controller machine . You should have an ansible folder, within this you should have a subdirectory venv27. if so activate your virtual environment.  $ source venv27/bin/activate If you decide to go by an alternative approach such as installing ansible using a system package  Please create an ansible directory now , you can continue with out the virtual environment  In the installation video we used the ansible command , check the installation was working as expected.  We are going to use the same ansible command to validate our system But this time we are going to work on a remote system .  We are going to make use of an ansible configuration and an inventory file. Before we d...

Ansible : UDMY -- 8. Ansible Inventories

Image
 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Ansible Architecture and Design  Ansible Inventory How can we provide connectivity to our Ansible hosts via root  There is a directory for each of these sections  As you can see there is a directory for each of these sections  essentially we can move to each directory and run ansible from each directory . Currently  our setup is quite simple we are connected as pact user connect to controller machine and using ansible as pack user connected to the end points. We are going to configure Ansible so that we can have *root* connectivity for all of our end points.  The centos systems are pretty simpler .  we have "ansible_user" variable set for centos hosts stating the user we will use for connectivity is root.  $ ansible all -m ping  the variable ansible_user hosts fails as we havent s...
