GLSA 201207-07 (Normal): keepalived

I rad some article. Keepalived over GRE tunnel for failover on VPS environment

http://blog.killtheradio.net/how-tos/keepalived-haproxy-and-failover-on-...

but, I don't know how to configuration?

I'm learning to use keepalived; for now within a single machine - just to make sure the forwarding works.

I've started a mock webserver listening on 192.168.56.200:8080.

I'm using Keepalived to manage two Redis instances in a master/slave configuration. I'm experiencing a situation where, if Keepalived is terminated on the Master box (the one with the higher priority), the Backup server takes over as the master.

I run on Ubuntu and i want to use TCP keepalived in order to implement hearbeat between master-slave.both servers are my impl (c++). I read this overview and did some google. i didnt understand what TCP keepalived send and i do know if connection is no longer valid when use in TCP keepalive ?. Do i need to check the revived content?

Hi every body.I have 2 server, each server has service mysql run on it.I have a problem when config keepalived for HA MySQL service. I've configed keepalived for loadbalancing. But... [by quyenlc]

JRuby: Denial of Service

Hi, I'm working on running 2 redis nodes as failover cluster. Keepalived migrating VirtualIP successfully, but still not clear how to run command on slave to be a master during failover.

Here is a config:

Code: !

I have a keepalived setup with three servers behind an ip. One is setup as a sorry server and only serves the maintenance pages, the other two are actual app servers.

I'v a couple of firewalls running Keepalived 1.1.15 (Debian Lenny), at the origin for the VRRP feature.

Then I added an LVS cluster with two 2 SMTP servers and lb_kind = NAT so our customers have transparent fallback and load-balancing.

The issue with this setup was that all other servers behind the firewall are unable to reach the SMTP LVS ip address (because of the lb_kind NAT).
