在Ubuntu上启动mysql集群管理节点(ndb_mgmd)时出错

Question

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
MySQL Cluster Management Server mysql - 5.5.25 ndb-7.2.7 2012-07-27 16:44:51 [MgmtSrvr] INFO - 默认配置目录'/ user/local/mysql/mysql-cluster'不存在.试图创建它...无法创建目录'/ usr/local/mysql/mysql-cluster',错误:2 2012-07-27 16:44:51 [MgmtSrvr]错误 - 无法创建目录'/ usr /本地/ MySQL的/ MySQL的群集".手动创建它或使用--configdir =指定不同的目录

〜$ ndb_mgmd --skip-config-cache -f /var/lib/mysql-cluster/config.ini

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.
