Hi All,I want to get an idea from you all about a scenario that i am facing..So i have 2 haproxy servers as load balancer primary and secondary, all the connections always go to primary, when primary fails i have keepalived running so the connections will fail-over to secondary
Now when i am upgrading i can upgrade secondary without any issues as the server never has active connections, but my question is how can i upgrade the primary without causing any downtime to my users. I have 2 Apache servers running behind the load balancers. so far i have tried the following on the primary , but have no luck..... echo "1" > /proc/sys/net/ipv4/ip_forward iptables -P FORWARD ACCEPT iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination <public_ip_secondary>:80 iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j DNAT --to-destination <public_ip_secondary>:443 iptables -t nat -A POSTROUTING -j MASQUERADE iptables -t nat -L -v my website does not get redirected to the secondary even after i do this.... any suggestions?
