Ansible install with openSUSE 13.2 and Mac

I start to study Ansible cause recently needs.

Ansible is python based, using SSH deploy packages to remote servers, it's like Puppet / Chef / Salt.

How to install Ansible

Install Ansible

• http://docs.ansible.com/ansible/intro_installation.html
• Mac OS - use pip to install
• $ sudo easy_install pip
• $ sudo pip install ansible

openSUSE 13.2 ( Most of linux could install ansible now )

Use zypper to query ansible package

# zypper   search   ansible

Loading repository data...

Reading installed packages...

S | Name    | Summary                                                                  | Type

Install Ansible

# zypper install  -y  ansible

That's all you need to do :-)

Ansible is clientless, that mean you don't need to install any packages in your remote hosts, it's the most diff with puppet and other tools.

The role is

• The control machine
• The one that you use to control remote machines
• needs to have python 2.6 or later installed.  
• To manage a server with Ansible
• Needs to have SSH and Python 2.5 or later installed.

Most linux has python later 2.5 ( Might be python 2.7 ), that's the reason - Nothing to install

What do you need to know? ( From Oreilly book ^^ )

I think the most important point is - you could use ssh and ssh key to execute some commands in remote servers.

What do I need to know?

• Connect to a remote machine using SSH.
• Interact with the bash command-line shell (pipes and redirection).
• Install packages.
• Use the sudo command.
• Check and set file permissions.
• Start and stop services.
• Set environment variables.
• Write scripts ( Any language )
• You don't need to know python to use Ansible unless you want to write your own module.
• You will need to learn some YAML and Jinja2 to use Ansible.     

That's all today, I will write some Ansible module command next time.
