1、环境描述
一台 10.0.0.201 SQL节点、管理节点
一台 10.0.0.202 做一个数据节点
一台 10.0.0.203做一个数据节点
2、安装Mysql_custter
在MGM管理节点、SQL节点、NDB节点执行同一操作
#:groupadd mysql
#: useradd mysql -g mysql -s /sbin/nologin
#: tar –xvf mysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz 
#:mv mysql-cluster-gpl-7.1.15-linux-x86_64-glibc23 /usr/local/mysql_cluster
#:vim /etc/profile
MYSQL_CLUSTER=/usr/local/mysql_cluster/bin
PATH=$PATH:$HOME/bin:$MYSQL_CLUSTER
export PATH
#: source /etc/profile
3、安装MGM管理节点
#:mkdir -p /opt/mgm/logs
#:mkdir /opt/conf
#:vim /opt/conf/config.ini
# Options affecting ndbd processes on all home/data nodes:
[ndbd default]
NoOfReplicas=2   #每个数据节点的镜像数量
DataMemory=200M  #每个数据节点中给数据分配的内存
IndexMemory=18M  #每个数据节点中给索引分配的内存
MaxNoOfAttributes=999999
MaxNoOfConcurrentTransactions=10240
LogLevelStatistic=15
LogLevelCheckpoint=15
LogLevelConnection=15
LogLevelError=15
LogLevelInfo=15
[ndb_mgmd]
NodeId=1
Hostname=10.0.0.201
Datadir=/opt/mgm/logs
LogDestination=FILE:filename=ndb_1_cluster.log,maxsize=10000000,maxfiles=6
ArbitrationRank=0
[ndbd]
NodeId=10
Hostname=10.0.0.202
Datadir=/opt/db2/data #管理节点数据(日志)目录
backupdatadir=/opt/db2/databak #管理节点数据(日志)目录的备份
[ndbd]
NodeId=11
Hostname=10.0.0.203
Datadir=/opt/db3/data  #管理节点数据(日志)目录
backupdatadir=/opt/db3/databak #管理节点数据(日志)目录的备份
[mysqld]
NodeId=20
[api]
[api]
[api]
[api]
[api]
启动管理节点:ndb_mgmd -f /opt/conf/config.ini --configdir=/opt/conf/
4、安装NDB管理节点
在202上
#:mkdir -p /opt/db2/data && mkdir /opt/db2/databak
#:mkdir /opt/conf
#:vim /opt/conf/my.cnf
[mysqld]
ndbcluster
ndb-connectstring=10.0.0.201
[mysql_cluster]
ndb-connectstring=10.0.0.201

在203上
#:mkdir -p /opt/db3/data && mkdir /opt/db3/databak
#:mkdir /opt/conf
#:vim /opt/conf/my.cnf
[mysqld]
ndbcluster
ndb-connectstring=10.0.0.201
[mysql_cluster]
ndb-connectstring=10.0.0.201
启动NDB节点
安装后第一次启动数据节点时要加上--initial参数,其它时候不要加,除非是在备份、恢复
配置变化后重启时
#: ndbd --defaults-file=/opt/conf/my.cnf --initial
5、安装SQL节点
#:groupadd mysql
#: useradd mysql –g mysql –s /sbin/nologin
#: mkdir -p /dbdata/data && chown mysql:mysql /dbdata/data
#:cp /usr/local/mysql_cluster/support-files/mysql.server /etc/init.d/mysql

#:vim /etc/init.d/mysql
basedir=/usr/local/mysql_cluster
datadir=/dbdadta/data
#:vim /usr/local/mysql_cluster/my.cnf
# Options for mysqld process:
[mysqld]
max_connections=200000
datadir=/dbdata/data/
log-error=/var/log/mysqld.log
port=3307
socket=/tmp/mysql.sock
character-set-server=utf8
default-storage-engine=ndbcluster
server-id=20
ndbcluster
# run NDB storage engine
ndb-connectstring=10.0.0.201
ndb-force-send=1
ndb-use-exact-count=0
ndb-extra-logging=1
ndb-autoincrement-prefetch-sz=512
#engine-condition-pushdown=1
ndb-cluster-connection-pool=1

key_buffer_size=16M
max_allowed_packet=10M
sort_buffer_size=256K
read_buffer_size=128K
read_rnd_buffer_size=256K
#table_lock_wait_timeout=16
memlock
sysdate_is_now
thread-cache-size=512
table-open_cache=512
max_prepared_stmt_count=24576
lower-case-table-names=0

# Timeout
interactive_timeout=43200
wait_timeout=43200
connect_timeout=60
skip-name-resolve
[ndbd]
connect-string=10.0.0.202
[ndbd_mgm]
connect-string=10.0.0.201
[mysql_cluster]
ndb-connectstring=10.0.0.201
# location of management server 
#:初始化
#cd /usr/local/mysql_cluster/scripts/
#./mysql_install_db --user=mysql --basedir=/usr/local/mysql_cluster/ --datadir=/dbdata/data/
常见报错:
Installing MySQL system tables.../usr/local/mysql_cluster//bin/mysqld: error while  
loading shared libraries: libaio.so.1: cannot open shared object file: No such file  
or directory
解决办法:#: yum -y install libaio
启动SQL节点
#:/etc/init.d/mysqld start
如果SQL启动失败。请保持虚拟机或者真实机的内存至少500M以上
6、测试与常见问题
启动顺序
MGM-->NDB-->SQL
关闭顺序
关闭
SQL-->MGM (NDB)
当关闭掉MGM后。NDB也会停掉

关闭MGM
ndb_mgm -e shutdown
测试:
ndb_mgm -e show
