MySQLCluster安装配置（二）

二、 Mysql Cluster --配置文件

1. my.cnf

每一个数据结点和SQL结点需要配置一个my.cnf文件，该文件包含两条信息：一条连接信息找到管理结点，一条配置ndbcluster存储引擎

vi /etc/my.cnf

[mysqld]
# Options for mysqld process:
ndbcluster # run NDB storage engine
datadir=/mysqlcluster/SQLNode/mysql/data
basedir=/mysqlcluster/SQLNode/mysql
[mysql_cluster]
# Options for MySQL Cluster processes:
ndb-connectstring=192.168.120.9 # location of management server

2.config.ini

管理结点需要配置config.ini，可以配置有多少备份，多少内存和索引，如何找到数据结点和sql结点

shell> mkdir/mysqlcluster/ManageNode/mysql-cluster
shell> mkdir/mysqlcluster/ManageNode/ndb-log
shell> cd/mysqlcluster/ManageNode/mysql-cluster
shell> vi config.ini
[ndbd default]
# Options affecting ndbdprocesses on all data nodes:
NoOfReplicas=2 # Number of replicas
DataMemory=80M # How much memory to allocate for datastorage
IndexMemory=18M # How much memory to allocate for indexstorage
# For DataMemory andIndexMemory, we have used the
# default values. Since the"world" database takes up
# only about 500KB, thisshould be more than enough for
# this example Cluster setup.

[tcp default]
# TCP/IP options:
portnumber=2202 # This the default; however, you can use any
# port that is free for allthe hosts in the cluster
# Note: It is recommendedthat you do not specify the port
# number at all and simplyallow the default value to be used
# instead

[ndb_mgmd]
# Management processoptions:

[mysqld]
# SQL node options:
