Mysos is an Apache Mesos framework for running MySQL instances. It dramatically simplifies the management of a MySQL cluster and is designed to offer:

• Efficient hardware utilization through multi-tenancy (in performance-isolated containers)
• High reliability through preserving the MySQL state during failure and automatic backing up to/restoring from HDFS
• An automated self-service option for bringing up new MySQL clusters
• High availability through automatic MySQL master failover
• An elastic solution that allows users to easily scale up and down a MySQL cluster by changing the number of slave instances

Mysos is also being proposed as a project in the Apache Incubator.

A user guide is available. Documentation improvements are always welcome, so please send patches our way.

The project maintains an IRC channel, #mysos on irc.freenode.net

• Python 2.7
• Mesos Python bindings

Mysos uses Mesos Python bindings which consist of two Python packages. mesos.interface is on PyPI and gets automatically installed but mesos.native is platform dependent. You need to either build the package on your machine (instructions) or download a compiled one for your platform (e.g. Mesosphere hosts the eggs for some Linux platforms).

Since pip doesn't support eggs, you need to convert eggs into wheels using wheel convert, then drop them into the 3rdparty folder. See the README file for more information.

Make sure tox is installed and a mesos.native wheel for your platform is placed in 3rdparty/. Then run:

tox

Tox also builds the Mysos source package and drops it in .tox/dist.

The Vagrant test uses the sdist Mysos package in .tox/dist so be sure to run tox first. Then:

vagrant up

# Wait for the VM and Mysos API endpoint to come up (http://192.168.33.17:55001 becomes available).

./vagrant/test.sh

test.sh verifies that Mysos successfully creates a MySQL cluster and then deletes it.
