High availability VRRP/BFD and load-balancing for Linux

Keepalived is a routing software written in C. The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage loadbalanced server pool according their health. On the other hand high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for router failover. In addition, Keepalived implements a set of hooks to the VRRP finite state machine providing low-level and high-speed protocol interactions. In order to offer fastest network failure detection, Keepalived implements BFD protocol. VRRP state transition can take into account BFD hint to drive fast state transition. Keepalived frameworks can be used independently or all together to provide resilient infrastructures.

Enable snaps on Red Hat Enterprise Linux and install keepalived

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 Red Hat Enterprise Linux (RHEL) 7, from the 7.6 release onward, from the Extra Packages for Enterprise Linux (EPEL) repository.

It is not yet available in the EPEL 8 repository, and consequently, not yet available for RHEL 8 unless you build the RPM yourself.

The EPEL repository can be added to your system with the following command:

Adding the optional and extras repositories is also recommended:

sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update

Snap can now be installed as follows:

Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:

To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:

Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
