ansible_instructions.txt

Following these instructions you would get three virtual machines , whereas one would be a server (ansible machine)
from where ansible would install software into two remaining virtual machines (destination servers).

Prerequsets (installed on a host machine): 
 - virtual box
 - vagrant
 
List of software which will be installed on the destination servers (basic list, some dependencies will be installed as well):
 
 - git
 - nginx
 - php
 - composer
 - mysql
 - nodejs

Insturctions:

=====
Destination Servers
=====
On your host machine 

mkdir -p ~/Boxes/testServerOne
mkdir -p ~/Boxes/testServerTwo

vim ~/Boxes/testServerOne/Vagrantfile

paste there
```
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"
  config.vm.network "private_network", ip: "192.168.40.11"
  config.vm.host_name = 'server-provision-test01'
end
```
vim ~/Boxes/testServerTwo/Vagrantfile

paste there
```
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"
  config.vm.network "private_network", ip: "192.168.40.12"
  config.vm.host_name = 'server-provision-test02'
end
```

cd ~/Boxes/testServerOne
vagrant up

cd ~/Boxes/testServerTwo
vagrant up

=======
Ansible Box
=======
On your host machine

mkdir -p ~/Boxes/ansibleBox
cd ~/Boxes/ansibleBox
git clone https://github.com/scotch-io/scotch-box.git ./
vagrant up
vagrant ssh

Inside the ansible box

cd ~/.ssh/
ssh-keygen -t rsa
(please accept the default file name and leave a passphrase empty)

cd ~/
ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.40.11
ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.40.12

if you had it copied under same ip but for a different machine it would complain about the changed authentication 
so please remove it from this box known hosts first

ssh-keygen -f "/home/vagrant/.ssh/known_hosts" -R 192.168.40.11
ssh-keygen -f "/home/vagrant/.ssh/known_hosts" -R 192.168.40.12

Check if you could ssh to both hosts by doing:

`ssh 192.168.40.11` - to ssh to the first server. you should see `vagrant@server-provision-test01:~$`
`exit` - to come back to your ansible box - you sould see `Connection to 192.168.40.11 closed. vagrant@scotchbox:~$`
`ssh 192.168.40.12` - to ssh to the first server. you should see `vagrant@server-provision-test02:~$`
`exit` - to come back to your ansible box - you sould see `Connection to 192.168.40.12 closed. vagrant@scotchbox:~$`

then (please make SURE you are inside your ansible box)

sudo apt-add-repository -y ppa:ansible/ansible
sudo apt-get update
sudo apt-get install -y ansible

sudo mv /etc/ansible/hosts /etc/ansible/hosts.orig
sudo vim /etc/ansible/hosts

and paste there 
```
[web]
192.168.40.11
192.168.40.12
[local]
127.0.0.1
```

mkdir -p ~/Code/Ansible/roles
cd ~/Code/Ansible/roles

Checkout some repos (we use https here rahter the git because this box is obviously not authenticated at github)

git clone https://github.com/geerlingguy/ansible-role-composer.git
git clone https://github.com/geerlingguy/ansible-role-git.git
git clone https://github.com/geerlingguy/ansible-role-mysql.git
git clone https://github.com/geerlingguy/ansible-role-nginx.git
git clone https://github.com/geerlingguy/ansible-role-nodejs.git
git clone https://github.com/geerlingguy/ansible-role-php.git

(still inside of your ansible machine)

ls -la ~/Code/Ansible/roles/

you should have 6 folders there

For those 6 roles make some changes in files and folders



for role ansible-role-nodejs

file tasks/main.yml

vim ~/Code/Ansible/roles/ansible-role-nodejs/tasks/main.yml

replace
nodejs_install_npm_user: "{{ ansible_user }}"
with 
nodejs_install_npm_user: "vagrant"

create a new directory 

mkdir -p ~/Code/Ansible/roles/ansible-role-nodejs/vars

vim  ~/Code/Ansible/roles/ansible-role-nodejs/vars/main.yml

and paste there
nodejs_version: "6.x"
nodejs_npm_global_packages:
  - name: eslint

file tasks/setup-Debian.yml

vim ~/Code/Ansible/roles/ansible-role-nodejs/tasks/setup-Debian.yml

replace
- name: Add Nodesource apt key.
  apt_key:
    url: https://deb.nodesource.com/gpgkey/nodesource.gpg.key
    state: present
with
- name: Add Nodesource apt key (due to an issue with apt_key we need to add it using this way)
  shell: 'curl --silent https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add - '
  register: node_key

and add a line
when: node_key|success

after

- name: Add NodeSource repositories for Node.js.
  apt_repository:
    repo: "{{ item }}"
    state: present
  with_items:
    - "deb https://deb.nodesource.com/node_{{ nodejs_version }} {{ ansible_distribution_release }} main"

  register: node_repo




for role ansible-role-php

with 
php_enable_php_fpm: true


file tasks/setup-Debian.yml

vim ~/Code/Ansible/roles/ansible-role-php/tasks/setup-Debian.yml

at the beginning of the file add 

- name: Add PHP7 Repository
  apt_repository: repo='ppa:ondrej/php' state=present
  register: ppaphp
  
after those two lines 
 - name: Update apt cache.
   apt: update_cache=yes cache_valid_time=86400

add one more line
  when: ppaphp|success

  
file vars/Debian.yml

vim ~/Code/Ansible/roles/ansible-role-php/vars/Debian.yml

replace 
__php_webserver_daemon: "apache2"
with 
__php_webserver_daemon: "nginx"





for role ansible-role-composer

vim ~/Code/Ansible/roles/ansible-role-composer/defaults/main.yml

replace 
composer_home_owner: root
composer_home_group: root
with
composer_home_owner: vagrant
composer_home_group: vagrant




Create main playbook file

vim ~/Code/Ansible/server.yml

and paste there
```
---
- hosts: web
  vars_files:
    - roles/ansible-role-nodejs/vars/main.yml

    - ansible-role-nginx
    - ansible-role-php
    - ansible-role-composer
    - ansible-role-mysql

check if your ansible hosts are reachable

ansible web -m ping


Run ansible playbook

cd ~/Code/Ansible/

ansible-playbook -s server.yml
