TODO: More detailed description.
First, ensure the machines you are deploying to meet the requirements:
- Clean installation of RedHat EL or CentOS 6 (please help to extend to other OSes)
- SSH access with keys & sudo rights
- Valid hostname which resolves in DNS
Next, ensure your control machine (likely your workstation) has the tools it needs:
- Ansible: http://docs.ansible.com/intro_installation.html#installing-the-control-machine
- python-keyczar:
pip install --pre python-keyczar - Tip: OSX users use Homebrew:
xcode-select --install
ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
pip install --pre python-keyczar
brew install ansibleThen get the files:
- clone the repository:
git clone https://github.com/seanorama/ansible-ambari.git && cd ansible-ambari - or download as a zip
Edit the configuration where appropriate. At the very least you must add hosts and SSH details
| File | Option | Description |
|---|---|---|
| hosts | [ambari], [master1], [master2] | put 1 hostname below each of these sections |
| hosts | [slaves] | put as many hostnames as you like below this |
| hosts | ansible_ssh_user= |
set to the user you can access the machine with. They should have ssh access. |
| hosts | ansible_ssh_private_key_file |
path to the ssh private key to access the machines |
| group_vars | whatever you like | the deployment will work without this, but you may want to change passwords, the cluster name, ... |
