Keepalived Vrrp Problem

Hey guys,

I’m trying to install keepalived 1.2.19 on a CentOS 6.5 machine. I did an install from source.

And when I start keepalived this is what I’m seeing in the logs. It’s reporting that the VRRP_Instance(VI_1) Now in FAULT state.

Here’s more of that log entry:

    Two stupid questions:
    1. Why are you running 6.5, rather than 6.7?
    2. On the host, does it *have* an eth0, or is it, perhaps, em1?

    Maybe there is a confusion here. Sounds like Tim thought keepalived would create that eth1, like a tunnel interface, but it won’t. You have to specify an interface that actually exists so that the VIP address will be added as a secondary address to ip to that interface.

  • Guys,

    I actually found a solution to this. After much googling I was able to come up with this:

    vrrp_instance VI_1 {
    interface eth1
    state MASTER
    virtual_router_id 51
    priority 101 # 101 on master, 100 on backup
    *dont_track_primary*
    vrrp_unicast_bind 10.40.116.30 # Internal IP of this machine vrrp_unicast_peer 10.40.116.31 # Internal IP of peer virtual_ipaddress {
    10.40.116.34
    }

    The key to getting this to work was to add the entry you see in bold above to the config. dont_track_primary. I’m not sure if that’s the best way to solve this problem. But I know that adding that line allowed me to do what I needed to do. After that I could ping the virtual address.

    Thanks for all the suggestions.

  • I had same issue keepalived running in Oracle Linux 7 and I just changed my vrrp_instance ID and virtual_router_id to different number and it work for me. I was also using VI_1.

    So in your case you just need to change vrrp_instance VI_1 to something else (may be vrrp_instance VI_12 ) on both master and back up.
