The ec2-hibinit-agent enables hibernation support on Amazon EC2
instances. It prepares the system for hibernation by managing
the swap space used to save the instance memory, and ensures
proper restoration of the system state upon resume.
This allows EC2 instances to pause and resume efficiently without
losing in-memory data.
Enable snaps on CentOS and install ec2-hibinit-agent
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Enable snapd
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
