Virtual machine cloning tutorial-for cluster construction, etc.

One, clone

Multiple machines are needed to build a cluster, you can use cloning to quickly build multiple machines

First find the machine to be cloned.
Right-click —> Manage —> Clone.

Select the current status of the virtual machine.

Select Create a full clone.

Change the name and save path of the virtual machine

. After cloning is complete, in

order to make the cloned virtual machine become an independent new virtual machine, you need to Change its MAC address, hostname and IP address

---

2. MAC address

Right click on the virtual machine —> Settings to

generate a new MAC address

---

Three, hostname

Modify hostname

[root@master01 ~]# hostnamectl set-hostname master01
[root@master01 ~]# hostname
master01

If the hostname does not take effect, please restart the virtual machine

---

Fourth, modify the IP address

Modify the ip address and set it to static ip

[root@master01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33

Modify the network mapping and add the local ip mapping at the end

[root@master01 ~]# vi /etc/hosts

Remember to save and exit, and then restart the network service

[root@master01 ~]# systemctl restart network

At this point, a virtual machine is cloned
