# How much memory to allocate for index storage 
# For DataMemory and IndexMemory, we have used the 
# default values. Since the "world" database takes up 
# only about 500KB, this should be more than enough for 
# this example Cluster setup. # TCP/IP options: [TCP DEFAULT] 
portnumber=2202 # This the default; however, you can use any 
# port that is free for all the hosts in cluster 
# Note: It is recommended beginning with MySQL 5.0 that 
# you do not specify the portnumber at all and simply allow 
# the default value to be used instead # Management process options: [NDB_MGMD] hostname=192.168.1.251 
# Hostname or IP address of MGM node datadir=/var/lib/MySQL-cluster # Directory for MGM node logfiles # Options for data node "A": [NDBD] 
# (one [NDBD] section per data node) hostname=192.168.1.251 
 # Hostname or IP address datadir=/usr/local/MySQL/data 
# Directory for this data node's datafiles 
# SQL node options: [MySQLD] hostname=192.168.1.254 
#[MySQLD] #这个相当于192.168.1.251
