Work Note 4: Do not backup etc under SSH directory No password access steps between nodes

One: Root User Action Steps

1. first back up the management node /root/.ssh directory (safekeeping)

admin:~ # tar czvf root-.ssh.tar.gz. ssh/

2. edit the known_hosts file in the/root/.ssh directory

admin:~ # Vi. Ssh/known_hosts

3. Delete all the public key files for the brush node, such as entries for cin021 and cin021-eth1 , and then save the exit

4. Copy the /root/.ssh directory to the/root directory of the Brush node (the first time you want to enter Yes )

admin:~ # Scp-r/root/.ssh/cin021-eth1:/root/

5. copy the /etc/hosts file to the/ etc directory of the re-brush node

admin:~ # scp/etc/hosts cin021-eth1:/etc/

6. finally copy the /root/.ssh/known_hosts file to all nodes

◆ before 9 Replication of Nodes

admin:~ # for I in ' seq 1 9 '; Do scp/root/.ssh/known_hosts cin00$i:/root/.ssh/;d One

◆ Ten to the last node, such as Ten to the in

admin:~ # for i in ' seq ten '; do scp/root/.ssh/known_hosts cin0$i:/root/.ssh/; Done

Second: normal user operation

★ General Users only need to be in NIS Server actions, such as user Tom

1 . first back up the . SSH directory (safekeeping)

[Email Protected]:~>tar czvf tom-.ssh.tar.gz. SSH

2. edit the known_hosts file in the/tom/.ssh directory

[e-mail protected]:~> vi. ssh/known_hosts

3. Delete all the public key files for the brush node, such as entries for cin021 and cin021-eth1 , and then save the exit

4. finally , ssh access to the swipe node, such as cin021-eth1 or cin021(the first time you want to enter Yes)
