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

These playbooks require Ansible 2.9.

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.

This LAMP stack can be on a single node or multiple nodes. The inventory file 'production' 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 production 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.

Development and Deploy Setup

    pip3 install --upgrade virtualenv
    python3 -m venv venv
    . venv/bin/activate
    pip install -r requirements.txt

Usage

    ansible-pull -U https://github.com/derektamsen/sysmgmt_playbook.git \
      --inventory production \
      site.yml

Run ansible for specific roles against remote hosts

    ansible-playbook site.yml -i production --limit retropies

List facts from host

    ansible -i production -m setup hostname

Create a new role playbook

    ansible-galaxy init roles/new-playbook-name
