mysql-cluster 7.3.5安装部署

Posted 2020-10-12 夏天一去，又是冬季

集群环境

管理节点    10.0.0.19
数据节点    10.0.0.12     10.0.0.17
sql节点      10.0.0.18     10.0.0.22

添加mysql用户

groupadd mysql
useradd mysql -g mysql  

安装mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64.tar.gz

cd /home/test

tar -zxvf mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64.tar.gz -C /usr/local

mv mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64/  mysql

cd ../

chown -R mysql:mysql mysql/  

cd mysql

./scripts/mysql_install_db --user=mysql   


这个步骤所有服务器都需要执行(5台)

集群配置

管理节点

vim /usr/local/mysql/config.ini

#lizhenghua

#必须有空的mysqld节点，不然数据节点断开后启动有报错  
[MYSQLD]  
id=6  
[mysqld]  
id=7  

启动管理节点

ndb_mgmd -f /usr/local/mysql/config.ini

关闭管理节点

[[email protected] bin]#ndb_mgm  

ndb_mgm> shutdowm

备注:命令行中的ndb_mgmd是mysql cluster的管理服务器，后面的-f表示后面的参数是启动的参数配置文件。
如果在启动后过了几天又添加了一个数据节点，这时修改了配置文件启动时就必须加上--initial参数，不然添加的节点不会作用在mysql cluster中。

ndb_mgmd -f /usr/local/mysql/config.ini --initial

管理节点状态

ndb_mgm> show 查看各节点情况。  

ndb_mgm> all report memory 查看各数据节点使用情况  

ndb_mgm>create nodegroup 3;创建数据节点分组  

mysql> alter online table data_house reorganize partition; 调整分区数据  

数据节点

vim /etc/my.cnf （添加以下内容）

备注: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、恢复或配置变化后重启时
