Six: RAC01 and RAC0 2 configuration

6.1 SSH mutual trust

SSH mutual trust

Do both nodes (both oracle and grid users)

[oracle@ rac01 ~] $mkdir .ssh /

[oracle@ rac01] $ssh-keygen-t rsa

[oracle@ rac01] $ssh-keygen-t dsa

[oracle@ rac02 ~] $mkdir .ssh /

[oracle@ rac02] $ssh-keygen-t rsa

[oracle@ rac02] $ssh-keygen-t dsa

[oracle@ rac01 ~] # ssh rac01 cat .ssh / id_rsa.pub > > .ssh / authorized_keys

[oracle@ rac0 1 ~] # ssh rac0 1 cat .ssh / id_dsa.pub > > .ssh / authorized_keys

[oracle@ rac0 1 ~] # ssh rac0 2 cat .ssh / id_rsa.pub > > .ssh / authorized_keys

[oracle@ rac0 1 ~] # ssh rac0 2 cat .ssh / id_dsa.pub > > .ssh / authorized_keys

[oracle@ rac0 1 ~] # scp .ssh / authorized_keys rac0 2:.ssh/authorized_keys

[oracle@ rac0 1 ~] # chmod 700.ssh

[oracle@ rac0 1 ~] # chmod 6000.ssh / authorized_keys

[oracle@ rac02 ~] # chmod 700.ssh

[oracle@ rac02 ~] # chmod 6000.ssh / authorized_keys

Authentication: grid and oracle users do not need to enter a password to verify ssh native and another server, respectively.
