Hi,
I'm new to LVS, but after quite a bit of effort I believe I have installed
everything correctly. When I run the rc.lvs_dr script on my LinuxDirector,
some strange stuff happens. The script proceeds okay, but it severs my
external SSH connection. After running the script, I can only SSH to the
Director from one of the other servers on the same switch (e.g. one of the
real servers).
Moreover, when I try to connect to the virtual IP address using a Web
browser, the attempt times out. If I run "ipvsadm" on the Director, it sees
more than one connection attempt, but they all go into the "InActConn"
column. For example, here's the result when I only tried to connect once:
[root@www1 /root]# /sbin/ipvsadm
IP Virtual Server version 0.2.7 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 209.116.71.36:http rr
-> 209.116.71.39:http Route 1 0 3
-> 209.116.71.38:http Route 1 0 2
I have three servers colocated at a hosting company. The usable IP range is
<209.116.71.36-46>. They told me that my Netmask should be
<255.255.255.240>, and that my gateway is <209.116.71.33>. Each of the
servers has two NIC interfaces, but I'm only using one as described in the
LVS how-to. Here's my "lvs_dr.conf":
#----------lvs_dr.conf--------------------------------------------------
LVSCONF_FORMAT=1.0
LVS_TYPE=VS_DR
INITIAL_STATE=on
CLEAR_IPVS_TABLES=yes
VIP=eth0:1 209.116.71.36 255.255.255.240 209.116.71.47
DIRECTOR_INSIDEIP=eth0 209.116.71.37 209.116.71.32 255.255.255.240
209.116.71.47
SERVICE=t http rr 209.116.71.38:80 209.116.71.39:80
SERVER_NET_DEVICE=eth0
SERVER_VIP_DEVICE=lo:1
SERVER_GW=209.116.71.33
#----------end lvs_dr.conf-----------------------------------------------
Am I missing something? Thanks so much in advance for any assistance you
can provide. I stupidly put myself on tight schedule to bring these servers
up.
