$ cat Id_rsa.pub >> Authorized_keys

$cat id_dsa.pub >> Authorized_keys

$ SCP Authorized_keys rac2:/home/grid/.ssh/----(input grid password, return to car)

Login RAC2:

$CD ~/.ssh

$ cat Id_rsa.pub >> Authorized_keys

$cat id_dsa.pub >> Authorized_keys

$ SCP Authorized_keys rac1:/home/grid/.ssh/----(input grid password, return to car)

Perform the next noodle operation in Rac1&rac2 , run several times .

$ ssh Rac1 date; SSH RAC2 Date

$ ssh Rac1-priv date; SSH Rac2-priv Date

Configure Oracle User Trust relationships

Landing Rac1,rac2 run separately :

$ su-oracle

$mkdir ~/.ssh

$chmod ~/.ssh

$ ssh-keygen-t RSA

$ ssh-keygen-t DSA

$CD ~/.ssh

$ cat Id_rsa.pub >> Authorized_keys

$cat id_dsa.pub >> Authorized_keys

$ SCP Authorized_keys rac2:/home/oracle/.ssh/----(Enter the oracle password. return car)

Landing RAC2:

$ su-oracle

$CD ~/.ssh

$ cat Id_rsa.pub >> Authorized_keys

$cat id_dsa.pub >> Authorized_keys

$ SCP Authorized_keys rac1:/home/oracle/.ssh/----(Enter the oracle password. return car)

Perform the following operations on RAC1&RAC2

$ ssh Rac1 date; SSH RAC2 Date

$ ssh Rac1-priv date; SSH Rac2-priv Date
