系统环境：Centos6.3 + mysql-cluster-gpl-7.1.15a-linux-x86_64-glibc23.tar .gz
说明：
1） MySQLCluster 的启动：
启动顺序：管理服务器 --> 存储节点 --> SQL 节点
2） 安全关闭 ndb cluster：
关闭顺序：SQL 节点 --> 数据节点 --> 管理节点。
# /usr/local/mysql/bin/mysqladmin-u root shutdown # 关闭 sql 节点
# /usr/local/mysql/ndb_mgm -e shutdown # 关闭管理节点， shutdown， 它会把所有 MGMNode 和所有 Data Node
的 ndb_mgmd 和 ndbd 都停止掉（mysql 还留着）
署操作步骤：
***系统内核调优必做****
一）部署 cluster 软件，所有机器
1） 下载 Cluster 软件 32 位 # wget-c http://downloads.skysql.com/archives/mysql-cluster-gpl-7.1/mysql-cluster-gpl-7.1.15a-linux-i686-glibc23.tar .gz 64 位 #wget-c http://downloads.skysql.com/archives/mysql-cluster-gpl-7.1/mysql-cluster-gpl-7.1.15a-linux-x86_64-glibc23.tar .gz 2） 安装与配置 Cluster useradd mysql-d/dev/null -s /sbin/nologin tar-xvf /usr/local/src/mysql-cluster-gpl-7.1.15a-linux-x86_64-glibc23.tar .gz -C /usr/local/src/ yum install rsync rsync -avl /usr/local/src/mysql-cluster-gpl-7.1.15a-linux-x86_64-glibc23//usr/local/mysql_cluster chown mysql:mysql/usr/local/mysql_cluster-R echo "P A TH=\$P A TH:/usr/local/mysql_cluster/bin/" >> /etc/profile source /etc/profile which mysql /usr/local/mysql_cluster/bin/mysql
二） 管理节点
1） 配置管理节点
mkdir /data/mysql/mgmd /data/mysql/ndb_data /data/mysql/ndb_data_backup /data/mysql/etc /data/mysql/binlog /data/mysql/mysql_data /data/logs -p chown mysql:mysql /data/mysql -R cat >/data/mysql/etc/config.ini << EOF [TCPDEF AUL T] SendBufferMemory=4M ReceiveBufferMemory=4M [NDB_MGMD DEF AUL T] PortNumber=1186 Datadir=/data/mysql/mgmd [NDB_MGMD] NodeId=1 Hostname=管理节点 IP 地址 LogDestination=FILE:filename=ndb_1_cluster .log,maxsize=10000000,maxfiles=6 ArbitrationRank=1 [NDBDDEF AUL T] NoOfReplicas=2 ServerPort=2200 Datadir=/data/mysql/ndb_data FileSystemPath=/data/mysql/ndb_data BackupDataDir=/data/mysql/ndb_data_backup DataMemory=9728M IndexMemory=1216M LockPagesInMainMemory=1 MaxNoOfConcurrentOperations=100000 MaxNoOfConcurrentT ransactions=16384 StringMemory=25 MaxNoOfT ables=4096 MaxNoOfOrderedIndexes=4096 MaxNoOfUniqueHashIndexes=512 MaxNoOfAttributes=24576 MaxNoOfT riggers=14336 ### Params for REDO LOG FragmentLogFileSize=512M InitFragmentLogFiles=SP ARSE NoOfFragmentLogFiles=38 RedoBuffer=48M T ransactionBufferMemory=8M TimeBetweenGlobalCheckpoints=1000 TimeBetweenEpochs=100 TimeBetweenEpochsTimeout=0 ### Params forLCP DiskCheckpointSpeedInRestart=100M DiskCheckpointSpeed=10M TimeBetweenLocalCheckpoints=20 ### Heartbeating HeartbeatIntervalDbDb=15000 HeartbeatIntervalDbApi=15000 ### Params for setting logging MemReportFrequency=30 BackupReportFrequency=10 LogLevelStartup=15 LogLevelShutdown=15 LogLevelCheckpoint=8 LogLevelNodeRestart=15 ### Params forBACKUP BackupMaxWriteSize=1M BackupDataBufferSize=24M BackupLogBufferSize=16M BackupMemory=40M ### Params for ODIRECT #Reports indicates that odirect=1 can cause io errors (os err code 5) on some systems.

2） 第一次启动管理节点【或者添加新节点了】：
ndb_mgmd -f /data/mysql/etc/config.ini--configdir=/data/mysql/etc/ 参数注意--initial
修改配置文件后启动方法：
ndb_mgmd -f /data/mysql/etc/config.ini--configdir=/data/mysql/etc/ --reload
三） 配置数据节点
cat >/data/mysql/etc/my .cnf << EOF
[MYSQL_CLUSTER]
ndb-connectstring="管理节点 IP"
EOF
第一次启动数据节点【以后启动禁止加入 initial 参数】：
ndbd--defaults-file=/data/mysql/etc/my .cnf 注意参数 --initial
四）配置启动 sql 节点
cat >/data/mysql/etc/my .cnf << EOF [MYSQLD] user=mysql basedir=/usr/local/mysql_cluster datadir=/data/mysql/mysql_data pid-file=/tmp/mysqld.pid socket=/tmp/mysql.sock port=3306 skip_name_resolve #ndb-cluster-connection-pool=4 ndbcluster=1 ndb-connectstring="管理节点 IP" ndb-force-send=1 ndb-use-exact-count=0 ndb-extra-logging=1 ndb-batch-size=24M ndb-autoincrement-prefetch-sz=1024 engine-condition-pushdown=1 default-storage-engine=ndbcluster #REPLICA TION SPECIFIC - GENERAL #server-id must be unique acrossall mysql servers participating in replication. #server-id=3 #REPLICA TION SPECIFIC - MASTER #log-bin=binlog #binlog-format=ROW #expire-logs-days=5 #LOGS log-error=/data/logs/error .log #log #log-slow-queries #OTHERTHINGS, BUFFERS ETC key_buffer_size = 256M max_allowed_packet = 16M #thread_cache_size=1024 myisam_sort_buffer_size = 8M memlock=0 sysdate_is_now=1 max-connections=3000 thread-cache-size=128 ###QUERY CACHE ISDISABLED ###THE QUERY CACHE IN MYSQL CLUSTER CAN HAMPER PERFORMANCEA LOT .

五）数据验证
在 sql 节点一操作：
mysql> use test; Database changed mysql> show tables; Empty set (0.11 sec) mysql> create table t1(a int) engine=ndb; ##<--需指定 ndb 引擎 Query OK, 0 rows affected (0.74 sec) mysql> insert into t1values(100); Query OK, 1 row affected (0.32 sec) 节点 sql2 上验证，用 root 查看效果 mysql> use test mysql> select *from t1 #<--发现有 100 这个记录为 OK。
