mkdir /var/lib/mysql/data

mkdir /var/lib/mysql-cluster

mkdir /var/run/mysqld

chmod -R 1777 /var/lib/mysql

chmod -R 1777 /var/run/mysqld

chmod -R 1777 /var/lib/mysql-cluster

cd /var/lib/mysql-cluster，在该目录下创建config.ini文件

关闭防火墙，关闭selinux，初始化密码在/var/log/mysqld.log文件中，首次登陆必须改密码，开启远程登录权限（也可设置只允许节点ip访问）

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

ndbd --initial

systemctl start mysqld.service
