防火墙配置：

MG 管理端配置：

1.禁用firewalld:

　　systemctl stop firewalld & systemctl disable firewalld

2.安装iptables 防火墙：yum -y install iptables-services
配置重点如下：

在/etc/sysconfig/iptables 添加如下规则

-A INPUT -p tcp -m state --state NEW -m tcp -s 192.168.0.0/24 -j ACCEPT

-A INPUT -p udp -m state --state NEW -m udp -s 192.168.0.0/24 -j ACCEPT

3.禁用SElinux ,请注意需要重启服务器
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

NDB 数据节点防火墙配置：

1.禁用firewalld:

　　systemctl stop firewalld & systemctl disable firewalld

2.安装iptables 防火墙：yum -y install iptables-services
配置重点如下：

在/etc/sysconfig/iptables 添加如下规则

-A INPUT -p tcp -m state --state NEW -m tcp -s 192.168.0.0/24 -j ACCEPT

-A INPUT -p udp -m state --state NEW -m udp -s 192.168.0.0/24 -j ACCEPT

3.禁用SElinux ,请注意需要重启服务器
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

Cluster 命令使用：

MG 管理端：
第一次启动命令(修改config.ini配置文件重新初始化)：

ndb_mgmd -f /var/lib/mysql-cluster/config.ini --initial

启动命令：

 ndb_mgmd -f /var/lib/mysql-cluster/config.ini

关闭命令：

ndb_mgm -e shutdown

查询状态命令：

ndb_mgm -e show

查询MG是否启动状态：

ps aux | grep ndb | grep -v grep

NDB 数据节点命令：

第一次启动：

ndbd --initial

重启：

ndbd

查询启动状态：

ps aux | grep ndb | grep -v grep

查看端口连接：

netstat -anpt

SQL 查询节点：

第一次启动, 请注意配置好my.cnf 文件之后再启动：

chown mysql:mysql -R /var/lib/mysql

mysqld --initialize-insecure
systemctl restart mysqld

安装软件说明：

MGM 管理端,：

安装命令如下，请查收安装时进入到软件所放置的目录下面；

yum -y localinstall mysql-cluster-community-*

NDB 跟MGM 安装一样；

SQL 安装有所不同，是因为安装插件：

yum install prel-Class-MethodMaker  perl-libwww-perl  perl-DBI  perl-GD perl-Data-Dumper

yum -y remove mariadb-libs

yum -y localinstall mysql-cluster-community-*

配置说明：
MGM 管理端：

配置文件所存放在：/var/lib/mysql-cluster/ 目录下面，所以首先要创建此目录：mkdir /var/lib/mysql-cluster/

MG config.ini 文件配置内容

NDB 数据节点配置：
因在MG 管理里面定义有backup 文件夹，所有首先要创建此文件夹，不然在重启过程中会报错从而不能成功启动节点：mkdir /var/lib/mysql-cluster/backup

配置文件为/etc/my.cnf 配置内容如下：

[mysqld]

ndbcluster

ndb-connectstring=192.168.0.105     # IP address of Management Node

[mysql_cluster]

ndb-connectstring=192.168.0.105     # IP address of Management Node

NDB my.cnf 配置内容

SQL 查询节点配置：

配置文件为/etc/my.cnf 请注意：第一次启动时先配置好此文件再初始化Mysql 再启动；

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]
