Dear Sir/Mdm:
I have setup the lvs on my redhat 6.2 machines(pls see attached the
lvs.cvf file)
What I did is to have one LVS router, and 4 real servers.
My questions are:
1) do I need to make any changes to the real servers?
2) I donno what went wrong,I have already done the followings, why
I still cannot ping to the public network(184.20.199.21)?This is a valid IP
when I ping from within the public network:
a) enable NAT
:>>edited the file /etc/sysct1.conf with the
following params and restarted the lvs server
i) net.ipv4.ip_forward = 1
ii)net.ipv4.ip_always_defrag = 1
b) enable IP masquerading
:>>ipchains -A forward -j MASQ -s 192.1.1.0/24 -d
0.0.0.0/0
c) at /etc/ , started the pulse
:>>./pulse start (it shows OK)
3) I am not sure what I have done this is correct:
:>>I have enable a direct routing at real server 192.1.1.24
by typing the following at the prompt:
ifconfig eth0:0 184.20.199.26 up ,whereby
184.20.199.26 is the virtual server IP.
when I ping from all the real servers(from 192.1.1.21 to
192.1.1.24) to 192.1.1.71(NAT router IP) it pings successfully!
when I ping from real server 192.1.1.24 to 184.20.199.26, it
pings successfully too!
when I ping from real server 192.1.1.24 to 184.20.199.21(which is
a valid public address), it says "Destination Host Unreachable"
when I ping from real servers 192.1.1.21,22,and 23 to
184.20.199.21, it says "Destination Host Unreachable" too!
Can you help me?May I know what steps that I might have missed out?
Thanks a million!
regards,
allan
