Error starting mysql cluster management node (ndb_mgmd) on Ubuntu

I am having trouble with the initial start up of the mysql-cluster management node and would appreciate any help I can get about this issue. See my two examples of failure below followed by my config.ini file. The first example shows the basic command to start the daemon and the error it produces. The second attempts to skip the process I believe caused the error in the first, but only results in a different error (one that I can find no solution to).


~$ 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 -- The default config directory '/user/local /mysql/mysql-cluster' does not exist. Trying to create it... Failed to create directory '/usr/local/mysql/mysql-cluster', error: 2 2012-07-27 16:44:51 [MgmtSrvr] ERROR -- Could not create directory '/usr/local/mysql/mysql-cluster'.

You should try running that commands with sudo:

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

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

Your problem seems to be with permissions, not configuration.
