Hi Phil, I have just been through this exact exercise. I have just posted my results to the Pound Proxy mailing list (so sorry to anyone that is a subscriber there, here is comes again!). This is the post I just sent, keepalived is so simple and I have it working with Pound and HAProxy;
Hi All, Thanks for all your responses! I have successfully implemented this now using keepalived. I would thoroughly recommend this to anyone looking for IP failover, is really easy to do. Download & compile which is as easy as; wget http://www.keepalived.org/software/keepalived-1.2.7.tar.gz gunzip keepalived-1.2.7.tar.gz tar -xf keepalived-1.2.7.tar cd keepalived-1.2.7/ sudo apt-get install libpopt-dev snmp snmpd libnl1 libnl-dev libssl-dev make libsnmp-dev ./configure --enable-snmp make sudo make install Then the following basic config will get you up and running with a basic set up; vrrp_instance pound_ips { state MASTER interface eth1 virtual_router_id 10 priority 100 advert_int 1 nopreempt virtual_ipaddress { 192.168.0.250 } authentication { auth_type PASS auth_pass bxUcbz52FE38 } } That reall is the bare minimum which will get you up and running. I made some notes here; http://null.53bits.co.uk/index.php?page=keepalived Cheers to all, James.
