#"0" means do not install server programs

#MySQL installation path
INST_PATH="/usr/local/mysql"
#Define the ports of MySQL installation, intput strings of
#PORT with whitespace separated.
#e.g. "3306 3307" means install two MySQL servers:
#     The first server will be installed to $INST_PATH/1 and listen 3306 port.

######### MySQL Cluster Config ############
###########################################
#Determine to install cluster
#"0" means do not install cluster programs

#Define COMPUTERs in config.ini, intput strings of HostName with
#whitespace separated.
#The Id attribute is auto increment and start with 1.
#e.g. "192.168.1.253 192.168.252" will generate the following code
#  [COMPUTER]
#    Id=1
#    HostName=192.168.1.253
#  [COMPUTER]
#    Id=2
#    HostName=192.168.1.252
COMPUTERS="192.168.1.253 192.168.1.252"
#Define MGMs in config.ini, intput strings of HostName with whitespace separated.
#e.g. "192.168.1.253 192.168.252" will generate the following code
#  [MGM]
#    HostName=192.168.1.253
#  [MGM]
#    HostName=192.168.1.252
MGMS="192.168.1.253"
#Define DBs in config.ini, intput ids of ExecuteOnComputer with whitespace separated.
#e.g. "1 2" will generate the following code
#  [DB]
#    ExecuteOnComputer=1
#  [DB]
#    ExecuteOnComputer=2
DBS="1"
#Define APIs in config.ini, intput ids of ExecuteOnComputer with whitespace separated.
#e.g. "1 0 1 2" will generate the following code
#  [API]
#    ExecuteOnComputer=1
#  [API]
#  [API]
#    ExecuteOnComputer=1
#  [API]
#    ExecuteOnComputer=2
