I am not making much progress, so any help would be very appreciated. I
installed a default Mandrake 10.1 (2.6 kernel) server installation and added
ipvsadm-1.24-2mdk.i586.rpm. Everything seemed to install fine (one NIC). I
edited /etc/sysconfig/ipvsadm and setup:
----------------
# servers being masqueraded by the LVS.
# see also ipvsadm(8).
-A -t 10.20.40.80:80 -s rr
-a -t 10.20.40.80:80 -r webip:80 -m -w 1
----------------
My servers IP address is 10.20.40.89
Starting the ipvsadm service, and running ipvsadm I see:
[root@localhost sysconfig]# ipvsadm
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.20.40.80:http wrr
-> webip:http Masq 1 0 0
--------------------------------------------------------
No traffic seems to go to the web box.
I then tried a script:
#!/bin/sh
#------mini-HOWTO-setup-LVS-NAT-director----------
#set ip_forward ON for vs-nat director (1 on, 0 off).
cat /proc/sys/net/ipv4/ip_forward
echo "1" >/proc/sys/net/ipv4/ip_forward
#director is gw for realservers
#turn OFF icmp redirects (1 on, 0 off)
echo "0" >/proc/sys/net/ipv4/conf/all/send_redirects
cat /proc/sys/net/ipv4/conf/all/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/default/send_redirects
cat /proc/sys/net/ipv4/conf/default/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/eth0/send_redirects
cat /proc/sys/net/ipv4/conf/eth0/send_redirects
#setup VIP
/sbin/ifconfig eth0:80 10.20.40.80 broadcast 10.20.40.255 netmask
255.255.255.0
#set default gateway
# /sbin/route add default gw 192.168.2.254 netmask 0.0.0.0 metric 1
#clear ipvsadm tables
/sbin/ipvsadm -C
#install LVS services with ipvsadm
#add telnet to VIP with rr sheduling
/sbin/ipvsadm -A -t 10.20.40.80:80 -s rr
#first realserver
#forward telnet to realserver 192.168.1.11 using LVS-NAT (-m), with weight=1
/sbin/ipvsadm -a -t 10.20.40.80:80 -r webip:80 -m -w 1
#check that realserver is reachable from director
ping -c 1 webip
#second realserver
#forward telnet to realserver 192.168.1.12 using LVS-NAT (-m), with weight=1
/sbin/ipvsadm -a -t 10.20.40.80:80 -r webip2:80 -m -w 1
#checking if realserver is reachable from director
ping -c 1 webip2
#list ipvsadm table
/sbin/ipvsadm
#------mini-HOWTO-setup-LVS-NAT-director----------
running ipvsadm gets the same results, but still no traffic.
Any additional thoughts? (I also tried Fedora Core 2, and RedHat ES v.3.0
U2)
