Add Virtual Machine node balancing data operations to the CDH cluster (Tutorial), cdh Virtual Machine

Note: The premise is that a new Virtual Machine node has been installed and the corresponding cdh has been installed. You can modify the host name, ip address, mac, and other operations on your own. This article only adds the cluster balance data operation to the Virtual Machine nodes with cdh installed.

1. View virtual machines

Virsh list-all

2. Modify Virtual Machine configurations (CPU, memory, and disk)

Switch to the Virtual Machine directory

Cd/ecars/vm/cdhslave07

Vim libvirt. xml

3. Remove and define virtual machines

Virtual Machine name, remove Virtual Machine

Virsh undfine cdhslave07

Redefinition of Virtual Machine definitions followed by xml

Virsh dfine libvirt. xml

4. Remove eth0 before starting the instance (skip this step and check again if an error is reported later)

Cd/

/Root/net. sh &

Check whether eth0 exists

Ip addr

Remove etho

Ifconfig eth0

Check whether eth0 exists

Ip addr

5. boot

Virsh start cdhslave07

(Shutdown virsh shutdown cdhslave07)

6. Check ssh

You only need to connect cdhmaster. If not, you need to configure ssh

Ssh cdhmaster

7. Add hosts to clusters in the cloudra management field

8. cloudra management interface cluster-hdfs-operation-rebalance
