Create an ssh equivalent user on two Centos servers

Create an equivalent user on two linux servers 2) create an equivalent user on node1: [root @ node1 ~] $ Mkdir ~ /. Ssh [root @ node1 ~] $ Chmod700 ~ /. Ssh [root @ node1 ~] $ Ssh-keygen-trsa [root @ node1 ~] $ Ssh-keygen create equivalent users on two linux servers 2) create equivalent users on node1: [root @ node1 ~] $ Mkdir ~ /. Ssh [root @ node1 ~] $ Chmod 700 ~ /. Ssh [root @ node1 ~] $ Ssh-keygen-t rsa [root @ node1 ~] $ Ssh-keygen-t dsa at node2: [root @ node2 ~] $ Mkdir ~ /. Ssh [root @ node2 ~] $ Chmod 700 ~ /. Ssh [root @ node2 ~] $ Ssh-keygen-t rsa [root @ node2 ~] $ Ssh-keygen-t dsa 3) switch back to node1 and run [root @ raw1 ~]. $ Cat ~ /. Ssh/id_rsa.pub> ~ /. Ssh/authorized_keys [root @ raw1 ~] $ Cat ~ /. Ssh/id_dsa.pub> ~ /. Ssh/authorized_keys prompt: the following command will prompt you to enter the root password of node2, follow the prompt to enter. if the command fails, try again. Node1 node: [root @ node1 ~] $ Scp ~ /. Ssh/authorized_keys node2 :~ /. Ssh/authorized_keys node2 node: [root @ node2 ~] $ Cat ~ /. Ssh/id_rsa.pub> ~ /. Ssh/authorized_keys [root @ node2 ~] $ Cat ~ /. Ssh/id_dsa.pub> ~ /. Ssh/authorized_keys [root @ node2 ~] $ Scp ~ /. Ssh/authorized_keys node1 :~ /. Ssh/authorized_keys 4) ensure that both nodes have information about each other. The two machines execute each other. [Root @ node1 ~] $ Ssh node1 date [root @ node1 ~] $ Ssh node2 date [root @ node1 ~] $ Ssh node1-priv date [root @ node1 ~] $ Switch the ssh node2-priv date to node2 and execute [root @ node2 ~] $ Ssh node1 date [root @ node2 ~] $ Ssh node2 date [root @ node2 ~] $ Ssh node1-priv date [root @ node2 ~] $ Ssh node2-priv date
