Thread: Making clone server in Linux

I have server of REDHAT Linux 5 and I need another server to keep on functioning of clients when main server gets failed to work. Entire work would be allocated to second server and main server will be recovered then. So I want to know how I can do that. Any help would be appreciated.

This doesn’t have many modifications but few physical things are needed. This process contains taking backup of database. For every drive on server, you must create every clone disk. Image copy of whole server is moved to clone disks that you organized and require to maintain host name and IP Address of server or else clients got problems to access clone server.

It is needed to make account on server machine so that you do not concern to have password required to type after every update. This task would be performed in following way:

Generate Key Pairs :

Key pairs are mechanically based in ~/.ssh home directory of specific user. The ~ symbol is utilized to find home directory of user in Linux. Now
Open a terminal and type: ssh-keygen -t dsa

1- Share Public Key
