CentOS 6/RedHat 6

For CentOS 6 and Red Hat 6, you need to install cloud-init, cloud-utils-growpart, and dracut-modules-growroot. Cloud-Init has been installed in Installing Cloud-Init.

This section uses CentOS 6.9 as an example to describe how to install them.

  1. Check whether cloud-init, cloud-utils-growpart, and dracut-modules-growroot have been installed. If no, perform the following steps to install them. 
    [root@localhost ~]# rpm -qa | grep cloud-init
cloud-init-0.7.5-10.el6.centos.2.x86_64
[root@localhost ~]# rpm -qa | grep growpart
[root@localhost ~]# rpm -qa | grep growroot
[root@localhost ~]#
  2. Download cloud-utils-growpart-0.27-10.el6.x86_64.rpm and upload it to the VM as instructed in Upload Required Software Packages.

    You can download the package from:

    https://dl.fedoraproject.org/pub/epel/

  3. Run the following command to install cloud-utils-growpart:

    rpm -ivh cloud-utils-growpart-0.27-10.el6.x86_64.rpm

    [root@localhost redhat]# rpm -ivh cloud-utils-growpart-0.27-10.el6.x86_64.rpm

[root@localhost redhat]#
  4. Install dracut-modules-growroot.
    1. Run the following command:

      yum install -y https://archives.fedoraproject.org/pub/archive/epel/6/x86_64/epel-release-6-8.noarch.rpm

    2. Run the yum install dracut-modules-growroot command to install dracut-modules-growroot online.

      Enter y when the message Is this ok [y/N] is displayed.

    3. Run the dracut -f command to update the kernel.
  5. Run the commands in 1 again to check whether cloud-init, cloud-utils-growpart and dracut-modules-growroot are successfully installed.
