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.
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.
Snap is available for Linux Mint 18.2 (Sonya), Linux Mint 18.3 (Sylvia), and the latest releases, Linux Mint 19 (Tara) and Linux Mint 19.1 (Tessa).
You can find out which version of Linux Mint you’re running by opening System info from the Preferences menu. To install snap from the Software Manager application, search for snapd and click Install.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either restart your machine, or log out and in again, to complete the installation.
To install keepalived, simply use the following command:
