Prerequisite
Root account privileges are required to install cloud-init.
Procedure
The following operations demonstrate how to install cloud-init on CentOS Linux 7.5:
Connect to the virtual machine as the root user via SSH.
ssh root@<VM's IP address>
Alternatively, you can connect the virtual machine as an ordinary user via SSH and use sudo to execute subsequent installation commands.
Mount the ISO image within the guest operating system.
mkdir /mnt/<dir_to_mount_iso>
mount /dev/<cloudinit_iso_cdrom> /mnt/<dir_to_mount_iso>
<dir_to_mount_iso>: The directory used to mount the ISO image.
<cloudinit_iso_cdrom>: The device name of the CD-ROM where the ISO image is mounted when mounting the Arcfra VM Initialization Tool ISO image.
You can use either of the following commands to check the device name:
mkdir /mnt/cdrom
mount -o loop /dev/sr0 /mnt/cdrom
Execute the installation script.
bash /mnt/<dir_to_mount_iso>/cloud-init/tools/install_cloud_init.sh
If cloud-init is already installed in the current guest operating system, please follow the on-screen prompts to uninstall the existing cloud-init, then continue with the installation.
If cloud-init is not installed in the current guest operating system, please follow the on-screen prompts to complete the installation.
If the installation is successful, you will see the prompt Installation successful.
You can also directly enter the following command to uninstall the existing cloud-init by default and complete the installation of the new cloud-init.
bash /mnt/<dir_to_mount_iso>/cloud-init/tools/install_cloud_init.sh --auto-yes
