  8. Oct 23, 2015 · Inside, we will start by defining a health check for our HAProxy service by opening up a vrrp_script block. This will allow keepalived to monitor our load balancer for failures so that it can signal that the process is down and begin recover measures.
  9. HAProxy is a free, open source high availability solution, providing load balancing and proxying for TCP and HTTP-based applications by spreading requests across multiple servers.

  5. For Centos 7 you need to change to keepalive and I recommend letting the haproxy running on both the whole time. the current vrrp master gets the traffic as the IP is there. For this you need to configure the system to allow binding to IP address which are not currently up. To do this set net.ipv4.ip_nonlocal_bind=1 in /etc/sysctl.conf.
  6. Therefore, for every VIP defined in the ipfailover deployment configuration, the ipfailover pod must assign a corresponding vrrp-id. This is done by starting at --vrrp-id-offset and sequentially assigning the vrrp-ids to the list of VIPs. The vrrp-ids may have values in the range 1..255.

  9. VRRP driver shall support authentication-type MD5. The HAProxy driver must be updated to automatically add a security group rule that allows multi-peers to synchronize their states. Currently HAProxy does not support peer authentication, and state sync messages are in plaintext. At this point, VRRP shall communicate on the same tenant network.
