2. Host information

   192.168.10.10 node1.zzx.com

   192.168.10.11 node2.zzx.com

4. Configure host Domain names separately

   Hostname node1.zzx.com

   Hostname node2.zzx.com

   Modify the configuration separately vim/etc/sysconfig/network

   Modify Hostname=node1.zzx.com

   Hostnaem=node2.zzx.com

   Vim/etc/hosts

   Add 192.168.10.10 node1.zzx.com Node1

   192.168.10.11 node2.zzx.com Node2

7. Create SSH Trust to configure the NOD1NODE2 host

   1. Generate an SSHD secret key

   
   

   [[email protected] ~]# ssh-keygen-t rsa-f ~/.ssh/id_rsa-p '

   Generating public/private RSA key pair.

   Created directory '/root/.ssh '.

   Your identification has been saved In/root/.ssh/id_rsa.

   Your public key has been saved in/root/.ssh/id_rsa.pub.

   The key fingerprint is:

   b7:76:48:4f:ac:f8:e7:5e:d8:89:51:e4:ff:b7:c8:7c [email protected]

   2. Copy the secret key of the Node1 host to Node2

   [Email protected] ~]# ssh-copy-id-i ssh/id_rsa.pub [email protected]

   15

   The authenticity of host ' 192.168.10.11 (192.168.10.11) ' can ' t be established.

   RSA key fingerprint is 2e:ec:e9:b9:34:2c:c4:46:84:bf:85:ad:e9:22:17:3c.

   Is you sure want to continue connecting (yes/no)? Yes

   warning:permanently added ' 192.168.10.11 ' (RSA) to the list of known hosts.

   [email protected] ' s password:

   Now try logging to the machine, with "ssh" [email protected] ' ", and check in:

   . Ssh/authorized_keys

To make sure we haven ' t added extra keys so you weren ' t expecting.

5. Test access
