Hi,

Could anyone let me know how to create 2 node cluster( Fault Tolerance + Load Balancing) for Sendmail Server.
I am using (CentOS5 + Sendmail)...

Thanks!!

Hi

This tutorial is not about sendmail exactley, it features svn ,but simply exchange the names and port numbers and this is a simple solution for tcp load balancing and failover.

Check out my guide to a simple tcp clustered service

Hope it helps !

Yes, Google can...did you look?

Also, any decent sendmail book can cover this, as well as their being lots of other solutions for load balancing, both commercial and open-source.

Thanks for replies , actually i am testing with heartbeat cluster service 1st node i created with ( CentOS 5 + sendmail + devecot + openwebmail ) , for 2nd node i have installed CentOS 5 with same settings and i want to mirror / sync all data /var/spool/mail + /etc/passwd + /etc/group / + /home/ etc ) that are required for running mail service.

If i sync with rsync /var/spool/mail and all other dirs , is it possible that users / users group / users home directories would be automatically sync and generating on the 2nd node and if 1st nodes gets down then 2nd node should come live without creating any problem to users.
......

Or any other thought do you have?

Any help would be greatly appreciated.

Thanks again.

You need shared storage, not syncing two seperate file systems ?

Yep, i think exactly i am looking for... Is it possible if i can have one hardrive and how to setup this actually in real enviornment.

Somethink like DRDB disk ? How to configure share storage for this purpose and tutorial for this..

Thanks again for reply..

DRDB can work for this...there are many tutorials on the Internet on how to set it up.

Ok... Thanks a lot for all replies , LinuxQuestions.org group is really gerat.
