在Ubuntu上启动mysql集群管理节点(ndb_mgmd)时出错

我在初始启动 mysql-cluster管理节点时遇到了问题,并且非常感谢我能解决这个问题.请参阅我的两个失败示例,然后是我的config.ini文件.第一个示例显示了启动守护程序的基本命令及其产生的错误.第二次尝试跳过我认为在第一次引起错误的过程,但只导致一个不同的错误(我找不到解决方案).

~$ndb_mgmd -f /var/lib/MysqL-cluster/config.ini

解决方法

您应该尝试使用sudo运行该命令：

~$sudo ndb_mgmd -f /var/lib/MysqL-cluster/config.ini

~$sudo ndb_mgmd --skip-config-cache -f /var/lib/MysqL-cluster/config.ini

您的问题似乎是权限,而不是配置.
