RE: Load balancing - Using only 2 servers-RH9.0

Dear Edward,

   Right now I am looking for Load balancing of Web servers with 2 Servers both acting as Director/Real Server.
   This is different from my earlier requirement of Failover of Samba service.Sorry if I confused you.
   In fact I have received a patch for doing this ( below mentioned) from Sebastien and I have applied this patch to
   the piranha source given by you.
 
   Out of 2 servers Node1 and Node2 I have installed piranha in Node 1 only.
   Node 1 - IP address : 151.8.26.201
   Node 2 - IP Address : 151.8.26.202
   Node1 2nd NIC: 10.0.0.1(Real Server address)
   Node 2 2nd NIC : 10.0.02(Real Address server)
   Virtual Server: 151.8.26.210
   NAT Router IP:10.0.0.254 

   Configured the default gateway as 10.0.0.254 for both Real Server IPs.
   Edited /etc/httpd/conf/httpd.conf on both the servers as Server name  10.0.0.1 & 10.0.0.2 respectively.
   Started httpd service on both the numbers.

   Started pulse on the Node1 and checked the ipvsadm -L and it has given a proper
 
 IP Virtual Server version 1.0.4 (size=65536)
 Prot LocalAddress:Port Scheduler Flags

 RemoteAddress:Port Forward  Weight ActiveConn InActConn

 TCP 151.8.26.210:http wlc
   -> 10.0.0.1:http         Masq     2     0              0
   -> 10.0.0.2:http         Masq     1     0              0

  when I have checked from an outside client (http://151.8.26.210) it has given the page on Node1
  But when I have stopped the httpd service from Node1 and tried above URL on client , it shown connection
  refused and taking the page from Node2.

  Please let me know what actually went wrong and what this patch is doing.

 Thanks n Regards,
 Sumesh

Sumesh, if you got the tar file that I sent you, then that is the
patched version of piranha. Untar it in the /usr/src/redhat/SOURCES
directory. cd /usr/src/redhat/SOURCES ; tar xzvf redhat.tar.gz
Then cd into the redhat/piranha directory and do the following:
make clean
make
make install
However, I noted that you said that you wanted to do LVS not FOS. You do
not need to recompile piranha if you do not need scripting in FOS. You
can use the version that comes with RHAS 2.1 if you only need scripting
with LVS.
When you first asked, you said that you needed scripting in failover,
that is why I sent you the tar file.
