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

These playbooks are meant to be a reference and starter's guide to building Ansible Playbooks. These playbooks were tested on CentOS 6.x so we recommend that you use CentOS or RHEL 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. The inventory file contains a grouped list of hostnames that are managed by Ansible. The command below will just add "localhost" to the host list.

    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 set up 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 local host and the dbserver on a server called "bensible". The stack can be deployed using the following command:

    ansible-playbook -i hosts site.yml

Once done, you can check the results by browsing to http://localhost/index.php. You should see a simple test page and a list of databases retrieved from the database server.
