Enterprise Mysql Cluster Project

Table of Contents

Project Objective: Purpose

The purpose is to set up a Highly Available clustered mysql database to support general computing. This is a term goal for Winter 2016, with a firm deadline of April 13th (meeting between Ken and CSCF Managers).

Project Scope/Deliverables

The high-level outcomes and results of this project are as follows:
  • we're agreed on a project plan and timeline DONE
  • new 3-node cluster with proper master/slave replication DONE
  • mysql.cs databases (list here) are moved to new cluster DONE
  • Marmoset is left behind on current mysql.cs DONE
  • appropriate resource, latency, and health monitoring of the database services DONE
  • wrapup includes:

Scope Includes/Excludes

Includes

  • high-speed dedicated storage network
  • asynchronous replication (master/slave, same process as set up by Clayton for yubikey)
  • failover process with acceptable downtime
  • tested failover and recovery, with (test instances of?) real applications and with no data loss (requires application experts - eg., Daniel for inventory)
  • necessary documentation
  • cluster deployment
    • PXE booting cluster
    • create salt pillar to build and deploy 3 mysql nodes on hardware cluster (Anthony and Clayton)
    • saltifying: mysql cluster backup (Anthony with Fraser)
    • benchmarking and testing mysql cluster performance (Fraser, Lori, Steve Weber)
  • migrate data from mysql.cs to cluster (Fraser)

Excludes

  • synchronous data replication (unless Clayton's instructions say it's trivial)
  • investigating additional mysql cluster setups
  • creating automated containers

Constraints

  • many current databases (list here) are critical; downtime must be pre-planned and minimized (no unscheduled downtime)
  • no user-level changes: two weeks before exams until last CS exam
  • end of term is April (23 - end of classes; 29 - last business day before new term)

Assumptions and Risks

  • marmoset can stay where it is on the non-clustered database, for this phase.
