Question

Cant start the management node on MySQL Cluster.

I am issuing the ff command.

ndb_mgmd -f /var/lib/mysql-cluster/config.ini –initial
–configdir=/var/lib/mysql-cluster/ –ndb-nodeid=1

And I am getting the ff error:

MySQL Cluster Management Server mysql-5.5.22 ndb-7.2.6 2012-07-05
02:45:24 [MgmtSrvr] ERROR — The hostname this node should have
according to theconfiguration does not match a local interface.
Attempt to bind ‘192.168.177.134’ failed with error: 99 ‘Cannot assign
requested address’

config.ini

[ndbd default]
NoOfReplicas=2

[ndb_mgmd]
hostname=192.186.177.134
datadir=/var/lib/mysql-cluster

[ndbd]
hostname=192.168.177.132
datadir=/usr/local/mysql/data

[ndbd]
hostname=192.186.177.133
datadir=/usr/local/mysql/data

[mysqld]
hostname=192.168.177.131

Answer 1

In config.ini, sometimes you have 192.168 and sometimes 192.186. In particular:

[ndb_mgmd]
hostname=192.186.177.134
datadir=/var/lib/mysql-cluster

Should be:

[ndb_mgmd]
hostname=192.168.177.134
datadir=/var/lib/mysql-cluster

The hostname will then match that to which ndb_mgmd was attempting to bind, as described in the error message. You should also correct the hostname in the [ndbd] section.
