Thanks Just Ice. Could you please explain me how to do it to generate the key pair for two servers inside ssh keys file?

It will be very helpful.

you generate the ssh keys in the same way as you would single server keys ... just add the public keys into the same .authorized_keys file ... but before you get lost there ...

first off, we need to know ...

1. direction of replication (i.e., prod to dr, dr to prod, both ways, etc.)

2. files and directories being replicated (i.e., ALL, /export/home, /, etc.)

3. domain/network of prod and dr servers (i.e., prod servers are in prod.some.com and network 192.168.1.0 while dr servers are in dr.some.com and network 192.168.15.0)

4. naming convention of prod and dr servers (i.e., server1 in prod and server1-d in dr)

Thank Ice Age.

Direction of replication :- One way (prod to dr).
files and directories being replicated completely (i.e., ALL, /export/home, /, etc.)
domain/network of prod and dr servers :- Production Host name and DR host name will be same but IP's will be different.
Naming convention of prod and dr servers is different. Server-1 and for DR Server-2

Reagrds,

I'm assuming that there must be some parts not replicated, such as the network configuration. How do you exclude these files? We might need to exclude a few others for the replication.

If you replicate absolutely everything, then if you DR server boots, it will get the IP address of the production server. If it is not isolated it could damage production services by getting in the way of your real production server. I'm assuming that you have identical hardware, else you might have issues booting anyway with device addresses all being wrong.


Is there a neat, yet complete definition of what for the OS filesystems is replicated rather than just everything? Do not worry about application & data filesystems information.

Yes Robin,

Netwrok configurations will be different. It implies IP address of each dr server will be differnt from the productions ones. So that in Host file, We will be having differnt IP addresses mentioned for DR servers.

So that tells me that you are not replicating everything. What is excluded?

Only hostfile will be excluded. DR servers will be having differnt hostfile than production servers.
