Revisiting my setup
Hi,
I having following setup for LVS-DR cluster.
Having 3 machine ( 1 director & 2 real servers) with following settings
Director
IP eth0 : 192.168.0.10 ( Netmask : 255.255.255.224 )
VIP eth0:1 : 192.168.0.110 ( Netmask : 255.255.255.224 )
Realserver 1
IP eth0 : 192.168.0.11 ( Netmask : 255.255.255.224 )
lo:0 : 192.168.0.110 ( Netmask : 255.255.255.255 )
Realserver 2
IP eth0 : 192.168.0.12 ( Netmask : 255.255.255.224 )
lo:0 : 192.168.0.110 ( Netmask : 255.255.255.255 )
* Enabled packet forwarding on Director
net.ipv4.ip_forward = 1
on both the real server I have disabled arp by making following entries in
/etc/sysctl.conf
( Kindly let me know if anything is wrong here )
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
When I do a telnet to port 25 to VIP.
It did not get any response
[root@client1 ~]# telnet 192.168.0.110 25
Trying 192.168.0.110...
But I observed that request is reaching Director but not getting passed to
realservers from there.
Checked following output
[root@localhost ~]# ipvsadm -L -n --stats
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Conns InPkts OutPkts InBytes
OutBytes
-> RemoteAddress:Port
TCP 192.168.0.110:25 36 56 0 3360
0
-> 192.168.0.11:25 22 33 0
1980 0
-> 192.168.0.12:25 14 23 0
1380 0
Not able to find out whats wrong :-(
I did LVS setup several time using LVS-NAT, but now facing lots of issues
with LVS-DR
