Assume that there are three servers with IP 10.9.1.101, 10.9.1.102, 10.9.1.103, respectively. Modify the Hosts file Modify the Hosts file (vi/etc/hosts) for each of the three servers, respectively,Added in the Hosts file10.9.1.101 node10110.9.1.102 node10210.9.1.103 node1032.

SSH does not enter a password to connect to a remote Linux host: public/private key verification. The public key is used for encryption, and the private key is used to decrypt data encrypted with the matched public key. Generate a key pair on the local machine, place the public key to the remote host, and then initiate an SSH connection from the local machine. Th
