Mysql ndb_Cluster 测试环境搭建

2015-05-07 11:26 537 查看

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

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

初始化数据库：
/usr/local/mysql_cluster/scripts/mysql_install_db  --basedir=/usr/local/mysql_cluster  --datadir=/data/mysql/mysql_data
--user=mysql
启动 sql 节点
mysqld  --defaults-file=/data/mysql/etc/my .cnf  --user=mysql &

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。
