|
# Purpose: Set up circular replication based on schema
|
|
# A->B->C->D->A
|
|
#
|
|
# Notes:
|
|
# 1. --slave-num=3 must be added to *-master.opt file
|
|
# 2. Even the test uses new names for servers but file names
|
|
# of log files are still old:
|
|
# master_a -> master.[log|err]
|
|
# master_b -> slave.[log|err]
|
|
# master_c -> slave1.[log|err]
|
|
# master_d -> slave2.[log|err]
