1. A host generates a key pairssh-keygen-t RSA2. The public key of host A is sent to Host BSCP id_rsa.pub Linux2:/cloud //SCP: is a command of the SSH protocol, remote replication3. Add a host's public key to the authorization list of Host B(1) General B host has just started and did not have this file, first and a as first created. SSH directoryssh-keygen-t RSA(2) Add the Authorized_keys file to the

Briefly describe the method: First, run the command ssh-keygen-t sra \ on the local machine to generate the RSA key. (This command generates a key pair: id_rsa and id_rsa.pub. They are saved in ~ by default ~ /. Ssh/directory. You can change id_rsa.pub to local_rsa.pub to avoid the same name as id_rsa.pub on the remote host. During the generation process, pass phrase is required. This is used to protect t

1. Background: The shell script executes the Kafka Start command on the main machine, and the other machines will also take this process. The previous script appears stuck every time it executes and cannot be returned to the command line.

Set ssh Public/Private Key logon mode and ssh public/private login Mode In Linux, ssh can be used to authenticate public and private keys when logging on to a remote host. ① Environment Description: two Linux Hosts, host1: 192.168.5.1, and host2: 192.168.5.10. Now set it on host1 and log on to host2 host. ② By default, the

Method One: Use Puttygen.exeThe first step: Creating a secret key Run Puttygen.exe, select the key type and length you want, use the default SSH2 (RSA), and set the length to 1024. Passphrase can be empty so that you don't have to enter a password at logon. Click the Save private Key button to save the public key and private key, for example, Key.ppk,public key does not need to be saved, then the Puttygen.exe load feature can be used to display the common key. Step Two: Upload the key Lo

Objective If you set a password before you created SSH, it's very likely that the git operation has a forgotten password. How to solve this situation. Workaround In this case do not think about how to re-modify the password, choose to re-create an SSH key, (PS: According to the investigation is git to ensure security does not have the option to re-modify the password). Let's first check if there is

Configure ssh password-free login and ssh password loginTake the root account as an example to prepare more than two Linux servers.
