Revision History: Setting up Master/Slave Replication from an existing MySQL server

This is revision 465 of the page Setting up Master/Slave Replication from an existing MySQL server, as it appeared on Wed, 16 Apr 2014 19:56:40 -0700.

Currently is running off a single MySQL server. I want to switch this to a master/slave setup, which I intend will:
  1. increase performance (0.10% of queries are blocked by updates), but not too much since the database is very write-heavy (59% of queries)
  2. increase visible performance greatly (often graphs are blocked by pending writes)
  3. improve reliability (if the slave goes down, I can point web servers to master; if the master goes down, I can enable read-only site mode)
  4. cost more money to run (since I'll be running two nodes rather than one) but still much cheaper (and more interesting) than going through S3
I'll be using the MySQL guide to set up replication and cover my steps here.
