在Ubuntu上启动mysql集群管理节点（ndb_mgmd）时出错

我在初始启动mysql集群管理节点时遇到问题，并希望得到有关此问题的任何帮助。请参阅我的两个失败示例，后面跟着我的config.ini文件。第一个例子显示了启动守护进程的基本命令及其产生的错误。第二次尝试跳过我认为会导致第一个错误的过程，但只会导致不同的错误（我找不到解决方法）。在Ubuntu上启动mysql集群管理节点（ndb_mgmd）时出错

你应该尝试运行使用sudo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

您的问题似乎与权限，而不是配置。

如果您使用RPM版本，则会安装一个mysql用户，您可以使用（例如，/ usr/sbin/ndb_mgmd和/ usr/sbin/ndbd）运行各种守护程序。只要确保目录设置正确并由'mysql'所有。 – plasmid87 2013-02-05 14:54:44
