我正在尝试在NDBCluster中的一个数据节点上启动mysqld。节点正确连接到管理服务器，但是当尝试启动mysqld时，启动失败时遇到我有的旧InnoDB表。我已经编辑了my.cnf以包含
[mysqld]
innodb=OFF
default-storage-engine=ndbcluster
并且这些更改在mysqld start的输出中被注明，但是在稍后遇到InnoDB表时它仍然会失败。有什么想法吗？ 下面包括
的输出mysqld --defaults-file=/etc/my.cnf

答案 0 :(得分：0)
整个树需要具有mysqld的合适文件/目录权限。
此外，您应该允许MySQL打开超过1024个文件。
