Install mysql-Cluster

System centos5.1 32-bit (how to use a 64-bit RPM package)

Http://dev.mysql.com/get/downloads/MySQL-Cluster-7.0 corresponds to the package name below

A total of five packages:

MySQL-Cluster-gpl-client-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-management-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-server-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-storage-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-tools-7.1.3-1.rhel5.i386.rpm

 

Three centos servers:

Management node (ndb_mgmd): 192.168.1.14

 

SQL Node 1 (mysqld): 192.168.1.15

SQL Node 1 (mysqld): 192.168.1.11

 

Data Node (ndbd): 192.168.1.15

Data Node (ndbd): 192.168.1.11

 

// -------------------------------------------------------------------- Start with this (this is used for all the seven hosts)

The first thing to do is to turn off the firewalls of the seven hosts (if not, every node cannot connect)

 

Disable Firewall:

Service iptables stop;

Flushing firewall rules: [OK]

Setting chains to policy accept: Filter [OK]

Unloading iptables modules: [OK]

How can I close it like this;

 

Create a folder:

Storage node: mkdir/var/lib/MySQL/Data

Management node: mkdir/var/lib/MySQL-Cluster

SQL node: yes or no

 

Grant permissions to two files:

Chmod-r 1777/var/lib/MySQL

Chmod-r 1777/var/lib/MySQL-Cluster

// -------------------------------------------------------------------- End with this

Initialize the database that starts the data node,

I used this mysqld_safe to start the SQL node & no error

After execution

100308 13:46:32 mysqld_safe logging to '/var/lib/MySQL/localhost. localdomain. err '.

100308 13:46:32 mysqld_safe starting mysqld daemon with databases from/var/lib/MySQL

The SQL node is successful.

 

Under the host of the Management node (192.168.1.14)

Cluster configuration
---------------------
[Ndbd (NDB)] 2 node (s)
Id = 2 @ 192.168.1.15 (mysql-5.1.44 ndb-7.1.3, node group: 0, Master)
Id = 3 @ 192.168.1.11 (mysql-5.1.44, nodegroup: 0)

[Ndb_mgmd (MGM)] 1 node (s)
Id = 1 @ 192.168.1.14 (mysql-5.1.44 ndb-7.1.3)

[Mysqld (API)] 3 node (s)

Id = 15 @ 192.168.1.11 (mysql-5.1.44 ndb-7.1.3)
Id = 16 (not connected, accepting connect from any host)

 

The above information is displayed successfully.

If not connected appears, accepting connect from any host is not enabled for the SQL node.

When the mysql-5.1.39 ndb-7.0.9 appears, staring nodegroup: 0 indicates that the storage node is not started. If your configuration is correct (that is, your firewall is irrelevant)

Dynamic Update Node

Close management node my management node here is 1

If we add an ndbd Node

[Ndbd]

Save and exit

It starts successfully.

Restart each node.

The NDB node executes ndb_mgm> 2 restart on the Management node (you should know how to install it in ndb_mgm)

The SQL node executes service myql stop mysqld_save on the SQL node;

Show the results on the Management node.
