[PYTHON] Install and configure `pyenv` Ansible playbook

Introduction

CentOS6 python version 2.6.6? Then, the module installed by pip There were some things that didn't work, so install pyenv and upgrade the python version. I created an Ansible playbook for CentOS6. Click here for rbenv http://qiita.com/tbuchi888/items/fd2e8d7e1790d398b281

Main steps of construction

Do the following as root for CentOS6

1. Installation of pyenv
2. Installation of python version 2.7.8

playbook, Vagrantfile (Ansible provisoner), etc.

gits will be here. git clone https://gist.github.com/tbuchi888/03f2dccdd7726770cb0522260141ca41

site.yml

 - include: install_pyenv_without_proxy.yml

The version of python is specified in vars: python_ver: 2.7.8 of the playbook below, so please change it as appropriate.

The following is for Vagrant environment The following is vagrant up to start the Server of CentOS 6 and build the pyenv environment using Ansible provisoner.

For the box file name, replace it with the box file name of CentOS 6 in your environment. Especially in the case of a 32-bit machine environment, please replace it with the box file name of your own 32-bit version CentOS6.

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.
  # Please replace it with a BOX name of CentOS6 for one's own 32bit when your host is 32bit machine.
  config.vm.box = "geerlingguy/centos6"

  # Add ansible provisioner
  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "site.yml"
  end
end

How to use

-In the case of Vagrant environment where Ansible provisoner can be used on OSX etc. -Please prepare the above playbook and other materials before vagrant up. -For Ansible environment only -Prepare your own inventory host file and run the playbook on the CentOS 6 server. ʻAnsible-playbook -i inventory file site.yml`

Execution environment for the above playbooks, etc.
