Example Analysis of making centos-win2k16 by Image on openstack Cloud platform
Editor to share with you the openstack cloud platform image production centos-win2k16 example analysis, I hope you will learn something after reading this article, let's discuss it together!
1.1 Image Information
1.2 Virtio driver information
Download address: https://cloudbase.it/downloads/CloudbaseInitSetup_Stable_x64.msi
2. KVM environment preparation
2.1 Virtualization software is installed on the physical machine that makes the image
Yum group install "Virtualization Host" >
2.3 create an empty image file
Qemu-img create-f qcow2 centos-7.6.qcow2 5G
Create a virtual machine virt-install-- name centos-7.6-- ram 1024-- cdrom=/home/ username / CentOS-7.6-x86_64-bin-DVD1.iso-- disk path=/home/ username / centos-7.6.qcow2-- noautoconsole-- os-type=linux
2.5 call up the qemu console
Virt-manager
3. Create Linux (CentOS7.6) image template 3.1 set the first login to change the password
Passwd-e root
3.2 disable SELINUX
Sed-I'/ ^ SELINUX/s/enforcing/permissive/g' / etc/selinux/config
3. Turn off Firewall
Systemctl disable firewall
3.4 GRUB configuration
* * [root@localhost ~] # * * cat / etc/default/grub | tail-n 1
* * [root@localhost ~] # * * GRUB_CMDLINE_LINUX_DEFAULT = "console=tty0 console=ttyS0,115200n8"
Grub2-mkconfig-o / boot/grub2/grub.cfg
Qemu-guest-agent cloudbase-init in Centos7.6 has been installed and started by default.
3.5 Edit / etc/cloud/cloud.cfg configuration file and cloud_init_modules add:
... -resolv-conf...
And since the requirement is to allow root users to remotely ssh virtual machines, the configuration should be modified to the following items in the / etc/cloud/cloud.cfg file:
Disable_root: 0 ssh_pwauth: 1
Add the following line to / etc/sysconfig/network to avoid problems accessing the EC2 metadata service:
NOZEROCONF=yes
3.6 time server
3.7 shut down the virtual machine
Poweroff
3.8 compress and reset the mirror
Virt-sysprep-d centos-7.6
Virt-sparsify-compress centos-7.6.qcow2 centos-7.6-cloud.qcow2
3.9 upload to the cloud platform (you need to log in to Openstack users with appropriate permissions)
Openstack image create-disk-format qcow2-public-file Centos_7.6.qcow2 Centos_7.6-property hw_qemu_guest_agent=yes
4. Create a Windows Server (2K16Std) image template
4.1 create a virtual machine to create an empty qcow2 file
Qemu-img create-f qcow2 win_2016.qcow2 15g
Virt-install-name win2k16-vcpus 2-ram 2048-cdrom=/windows/win/cn_windows_server_2016_x64_dvd_9718765.iso-disk path=win_2016.qcow2-channel unix,path=/var/lib/libvirt/qemu/channel/target/win2k16.agent,mode=bind,target_type=virtio,name=org.qemu.guest_agent.0
4.2 acquisition of Virtio-win driver installation software
Wget https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/virtio-win.iso
Add a mirror to the mirror of a virtual machine
Install the driver at the beginning of the installation
Register for the balloon service
4.4 Open a remote connection
4.5 disk policy configuration
4.7 time server
Compress mirror image
Virt-sparsify-compress win16.qcow2 win_16.qcow2
Upload to the cloud platform
Openstack image create-- disk-format qcow2-- public-- file win_16.qcow2 win_16.qcow2-- property hw_qemu_guest_agent=yes-property os_admin_user=administrator
