CentOS 7/RedHat 7/Oracle Linux 7

CentOS 7, RedHat 7, and Oracle Linux 7 use the 3.10 (>3.8) kernel. Therefore, you do not need to install dracut-modules-growroot. You only need to install cloud-init and cloud-utils-growpart. Cloud-Init has been installed in Installing Cloud-Init.

This section uses CentOS 7.3 as an example to describe how to install them.

  1. Check whether cloud-init and cloud-utils-growpart 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.el7.centos.1.x86_64
[root@localhost ~]# rpm -qa | grep growpart
[root@localhost ~]#
  2. Run the following yum command to install cloud-utils-growpart online.

    yum install cloud-utils-growpart

  3. Check whether cloud-utils-growpart is installed successfully.
    [root@localhost ~]# rpm -qa | grep growpart
cloud-utils-growpart-0.29-2.el7.noarch
