ANXS - MySQL

Ansible role that installs MySQL on (for now) Ubuntu variants. Features include:

• Installation of MySQL and it's dependencies
• Basic configuration
• Standard hardening (root password, removal of test databases)
• Add databases
• Add users
• Setup of monit process supervision

Requirements & Dependencies

• Tested on Ansible 1.4 or higher.
• ANXS.monit if you want monit protection (in that case, you should set monit_protection: true)

Setting/Updating the root Password

If You would like to change your mysql root password using this role, ensure you use the following variables in your play:

mysql_default_root_password: <Your current root password>
mysql_root_password: <Your new root password>

Testing

This project comes with a VagrantFile, this is a fast and easy way to test changes to the role, fire it up with vagrant up, provision the box with either:

vagrant provision

This also happens automatically after the first vagrant up, or:

ansible-playbook test.yml -i vagrant-inventory --sudo

This is the ansible way, and will easily allow command line arguments like --tags and -e

See vagrant docs for getting setup with vagrant
