[solved] How to install centos without GUI on a virtual machine?

[Zefengwang]

Hello everyone!

I have recently encountered a problem, I need to install centos on a computer, after I need to install a virtual machine and install centos again on the macine.

ok, it's easy.

but I need to install them all without GUI, but all of them have it!!!
now I install centos on the computer with GUI and using mini install, it without GUI. its great.
but when I try virtual machine manager, it dependence the GUI lib. ok, fine . when I try to install client machine, it requests x11. so i give it up.

I try vbox, it can create vm (virtual machine) with command line, but when I run it at first with headless argument, I don't what to do next ......

so can you help me?
I need your help!

It is called kickstart installation.

steps:
1. prepare kickstart file
2. make it available to the VM (ex. on USB, or better via ftp server)
3. boot your VM as usual for regular install
4. at boot time specify extra boot parameter: location to kickstart file
5. enjoy install automation

Thank you! I will try it!
later I will give you the result!
Thank you again!

-----------------
sorry I have another question? Is there any Virtual Machine software without GUI dependence?
Both Virtual box and Virtual Machine Manager need install GUI lib. I don't need it.

------------------
yesterday I log the centos via Xshell for installing the centos without headless argument, but the vbox asks for x11 request.
so I use Xmanage. But it need authorization. I don't have it.
so I also need a vm without GUI.
Thank you aaaaaaaagain!

KVM+libvirtd

Code: Select all

sudo yum group install "Virtualization Host"
sudo systemctl start libvirtd

Than you can use virsh to manage VMs from CLI

There is also command virt-install (sudo yum install virt-install)

Most likely you will have to configure networking bridges...

5. enjoy install automation

step 4 implies GUI access... my bad

Alternative:
3. boot custom installation image (with your kickstart file included) (you will have to make it first... )
Since you can use any boot image on the CLI, I'd ignore PXE completely - it is simply not required.

Thinking out of the box:
Maybe creating the VM somewhere else (with GUI), and than copying the VM image file to the destination will be faster/easier?

here is my parameters:

sudo    virt-install \
        --name zf02 \
        --memory 2048 \
        --vcpus 2 \
        --location /home/zf/vm/iso/CentOS-7-x86_64-DVD-1810.iso \
        --boot menu=on \
        --disk size=10 \
        --network bridge=virbr0 \
        --graphics none \
        --console pty --extra-args 'console=ttyS0' \
        --boot useserial=on \

Now I know the ks.cfg file didn't work ....

I edited it as following:

Code: Select all

It works, but the disk status is not good, so the installation will stop.
can you tell me how to config it in kickstart file?

-------------------------------------------------------------------------------------------------------------------
ok. I configured it and it works now.

But I have another problem.
about the net.
my host net ip is 10.110.130.xxx,
my guest net ip is 192.168.122.xxx

I need to access the guest client from another computer addressed 10.110.130.xxx

so……

how to configure it ?


-------------------------------------------------------------
ok I did it

there is nothing left


Thank you very much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
