Building a simple LAMP stack and deploying Application using Ansible Playbooks.

This playbooks is meant to be a reference and starters guide to building Ansible Playbooks. These playbooks were tested on Centos 6.x so we recommend Centos to test these modules.

Installing Ansible

Running this playbook requires setting up Ansible first, luckily this is a very simple process on Centos 6.x:

    yum install http://epel.mirrors.arminco.com/6/x86_64/epel-release-6-8.noarch.rpm
    yum install python PyYAML python-paramiko python-jinja2
    git clone git://github.com/ansible/ansible.git
    cd ansible
    source hacking/env-setup

Generate/Synchronize your ssh keys(Optional you can pass -k parameter to prompt for password)

    ssh-keygen -t rsa
    cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Create a sample inventory file (File containing the hostnames)

    echo "localhost" > ansible_hosts

Test if we are setup properly

    ansible -i ansible_hosts localhost -m ping
            localhost | success >> {
                    "changed": false,
                    "ping": "pong"
            }

Now we setup our Lamp Stack, The stack can be on a single node or multiple nodes. The inventory file 'hosts' defines the nodes in which the stacks should be configured.

    [webservers]
    localhost

    [dbservers]
    bensible

Here the webserver would be configured on the localhost and the dbserver on bensible. The stack can be deployed using the following command.

ansible-playbook -i hosts site.yml

Once Done, you can check by browsing to http:///index.php

If you want to add a new webserver to the stack it would be as simple as changing the hosts file to add the new webserver name and rerun the above command.

    [webservers]
    localhost
    webserver1

    [dbservers]
    bensible

    ansible-playbook -i hosts site.yml
