Hi, I'm trying to set up load balancing with IPVS on two Apache webservers. The loadbalancer and both apache servers are virtual machines running Ubuntu 8.04 server on VMware ESX 3.5.
If the platform has been idle for some time (like when I came back to work this morning), I can point a browser to http://VIP and get pages from server1 or server2 alternatively (I'm using rr during setup). But after about 5 seconds, I get nothing and the browser times out. Here is my configuration on the load balancer : ipvsadm -A -t $VIP:80 -s rr ipvsadm -a -t $VIP:80 -r $RIP1:80 -g ipvsadm -a -t $VIP:80 -r $RIP2:80 -g On webservers, I added the following to /etc/sysctl.conf (as suggested on http://www.linuxvirtualserver.org/VS-DRouting.html) : net.ipv4.conf.all.hidden = 1 net.ipv4.conf.lo.hidden = 1 I rebooted them and then : ifconfig lo:0 $VIP netmask 255.255.255.255 up Unless I did something stupid (if so, please tell me), it should work. I also tried the following with no more luck : echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce I'm quite sure my problem is not on the loadbalancer but on webservers. Maybe I'm not using correct commands to prevent it from announcing the VIP ? Any help would be much appreciated. I already asked on ubuntu forums but I guess you guys are more used to these kind of problems... Thanks in advance for your time. _______________________________________________ LinuxVirtualServer.org mailing list - [email protected] Send requests to [EMAIL PROTECTED] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
