具体配置如下:(注意:如果/etc/目录下没有my.cnf文件,需要自己创建一个)
shell> vi /etc/my.cnfmy.cnf的内容为:
# Options for mysqld process:
[mysqld]
ndbcluster # run NDB storage engine
ndb-connectstring=192.168.0.10
# location of management server
# Options for ndbd process:
[mysql_cluster]
ndb-connectstring=192.168.0.10# location of management server
首先需要创建存放配置文件的文件夹及配置文件本身
shell> mkdir /var/lib/mysql-cluster
shell> cd /var/lib/mysql-cluster
shell> vi config.ini
文件的内容示例如下:
# Options affecting ndbd processes on all data nodes:
[ndbd default]
NoOfReplicas=2 # Number of replicas
DataMemory=80M # How much memory to allocate for data storage
IndexMemory=18M # 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 the cluster
# Note: It is recommended that you do not specify the port
# number at all and allow the default value to be used instead
# Management process options:
[ndb_mgmd]
hostname=192.168.0.10 # Hostname or IP address of management node
datadir=/var/lib/mysql-cluster # Directory for management node log files
# Options for data node "A":
[ndbd]
# (one [ndbd] section per data node)
hostname=192.168.0.30 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files
# Options for data node "B":
[ndbd]
hostname=192.168.0.40 # Hostname or IP address
datadir=/usr/local/mysql/data # Directory for this data node's data files
# SQL node options:
[mysqld]
hostname=192.168.0.20 # Hostname or IP address
# (additional mysqld connections can be
# specified for this node for various
# purposes such as running ndb_restore)
