cd ansible
git checkout -b stable-2.1 origin/stable-2.1
git submodule update --init --recursive
sudo make install

Ansible Structure and Yaml format

-myproject
  - roles
    - redis
        - files
        - meta
        - tasks
            - main.yml
  -redis.yml

redis.yml

---

- hosts: 127.0.0.1
  sudo: yes

  vars:
    myvar: 10

  roles:
  - redis

Them in your main.yml you do like:

---

- name: ensure yum is updated
  action: yum name=* state=latest

- name:  ensure Git is present
  action: yum pkg=git state=present

Or.... if you dont want to import the role you can do:

---

- name: ensure yum is updated
  tasks:
  - action: yum name=* state=latest

- name:  ensure Git is present
  tasks:
  - action: yum pkg=git state=present

I needed to also install libffi-devel and openssl-devel to "make install" on Amazon Linux 2017.03. Thanks.

Cool @aharden

Also could do (ansible 2.4):

playbook.yml

---

- hosts: localhost
  tasks:
  - name: Redis - Override default configs
    lineinfile:
      dest=/tmp/ansible-redis/out.txt
      state=present
      regexp="{{ item.regexp }}"
      line="{{ item.line }}"
      backrefs=yes
    with_items:
      - { regexp: 'daemonize yes', line: 'daemonize no' }
      - { regexp: 'dbfilename dump[.]rdb', line: 'dbfilename nfredis.rdb' }
      - { regexp: 'bind 0.0.0.0', line: 'bind 127.0.0.1' }

ansible-playbook -i localhost playbook.yml

For CentOS / Amazon Linux -- You can just

sudo pip uninstall ansible
sudo pip install ansible

I made a simple sandbox to run ansible locally in docker using amazon linux: https://github.com/diegopacheco/ansible-docker

This works for me:

pip install --user ansible

Or, as someone else just pointed out to me:

sudo amazon-linux-extras install ansible2
