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
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.

Now, every config is ok , but when I use
./ndbd --initial
on data node , it will ouput log :
ndb_mgm :
Forced node shutdown completed. Occured during startphase 0. Caused by error 2350: 'Invalid configuration received from Management Server(Configuration error). Permanent error, external action needed'.

Now, the ndbd log tell me , it fetch configuration from server error, but I dont know where is the error.
Thsi is my management node configuration :
[ndbd default]
NoOfReplicas= 1
[mysqld default]
[ndb_mgmd default]
[tcp default]
[ndb_mgmd]
HostName= 172.19.16.170
[ndbd]
NodeId=2
HostName= 172.19.16.166
DataDir= /var/lib/mysql-cluster
[ndbd]
NodeId=3
HostName= 172.19.16.167
DataDir= /var/lib/mysql-cluster
[mysqld]
[mysqld]
[mysqld]
This is an upgrade issue. The error only occurs in ndbd up to
version 7.5. But it is only the ndb_mgmd from version 7.6 that
can set IndexMemory to 0. ConfigParam: 113 is IndexMemory which
is deprecated in 7.6. So probably you are running a ndb_mgmd from
version 7.6 and ndbd from version 7.5.

1) You started the management server fromt he wrong node, it is started
from 192.168.1.104, but in config it says it should be in
192.168.1.103.
2) You are missing a mysqld section for the second MySQL server at
192.168.1.105
Some recommendations:
1) Assign node ids to all nodes
2) Add an API node as well to enable running some NDB tools as well
I'm playing with MySql Cluster and faced a problem with not common configuration. The most of tutorials describes configuration where data node and MySQL Server node residing on the same PC. But I'm trying to put management node and MySQL server node to PC 'A' and data node to PC 'B'. Unfortunately when I'm trying to run data node ndbd.exe shutting down immediately and leaves the following message in Windows Event Viewer: "Failed to allocate nodeid, error: 'Error: Could not alloc node id at pcA.ip.address port 1186: Connection done from wrong host ip pcB.ip.address'.".
My configuration files are following:
PC 'A' config.ini:
[ndbd default]
noofreplicas=2
[ndbd]
hostname=pcB.ip.address
nodeid=2
[ndb_mgmd]
nodeid = 1
hostname=pcA.ip.address
[mysqld]
nodeid=4
hostname=pcA.ip.address
my.cnf used by mysqld on PC 'A':
[mysqld]
ndb-nodeid=4
ndbcluster
datadir="D:\ProgramData\MySQL\MySQL Cluster 7.3\data4"
port=3306
server-id=3306
my.cnf on PC 'B':
[ndbd]
connect-string="pcA.ip.address"
Can someone say what is wrong with these files above? As I said I couldn't find tutorirals for such cluster configuration.
Thanks in advance.
In your setup, you're declaring to replicas, but you have only one:
[ndbd default]
noofreplicas=2
Node configuration looks fine, but you could try using a empty ndbd definition, then reloading ndb_mgmd daemon to ensure it's applied

I am having trouble starting up ndb_mgmd. Here's some information.

When I execute:

MySQL Cluster Management Server mysql-5.5.25 ndb-7.2.7
[MgmtSrvr] ERROR -- Could not determine which nodeid to use for this node. Specify it with --ndb-nodeid=<nodeid> on command line
Any ideas as to why this is happening?
The problem was I wasn't connected to the network of the cluster.
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).

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.
