Re: Backup Web Server
#2 (vrrp) is a subset of #3 (LVS / keepalived / vrrp ) I have several boxes configured as master / backup routers with the VRRP component of keepalived. You just need to configure keepalived to not use LVS and then you have a clean and simple VRRP install.

Re: Backup Web Server
Theres a couple of ways you can do this. 1) round robin dns : 2 servers with their own IP's, each serving up the website. If one goes down, you still get a 50% success rate. 2) VRRP via keepalived - http://www.keepalived.org/ : 2 servers, 1 real floating IP that is bound to the active server. If the active server dies, the IP's are picked up by the standby server and keeps on going. 3) LVS ( Linux Virtual Server ) http://www.linuxvirtualserver.org/ : This is the most involved setup but will also give you the most scalability and availabilty by creating farms of local servers that the inbound requests are balanced across. It can also do enhanced checks on the local servers to make sure that only healthy nodes are answering requests.

Re: failing all vrrp interfaces.
It appears that the vrrp IP is removed when a regular kill signal is issued the the vrrpd PID. It was only when kill -9 was issued to the PID that the IP would be left on the interface. I've also decided to use keepalived (http://keepalived.sourceforge.net/) since its vrrpd implemenation is quite nice. I would highly suggest anyone looking into vrrp with linux take a look at keepalived. Cheers.

failing all vrrp interfaces.
The issue I'm trying to tackle is dealing with multiple interfaces in vrrpd. I need to make sure that all vrrpd daemons and aliases on the failed server are brought down. One thing I noticed is that if you kill the the vrrpd PID's, the vrrp virtual IP address is still aliased to the server that has its vrrpd processes killed. if you do an "ip address ls" you can see the virtual IP address bound to the interface. Any idea of how to drop the alias when the vrrpd daemon is killed ? Thanks.
