1. Preface This article briefly introduces how to use SSH for password-free login. All the operations are completed in UNIX.2. Principles Implemented through public key encryption and Private Key decryption. The User Machine sub-stores the private key and the remote machine sub-stores the corresponding public key. The remote host uses the public key to encrypt a piece of text for the user. The user's machine uses the private key to decrypt

When using Taskctl to dispatch a service, if you need cross-user or cross-server scheduling can be implemented by installing TASKCTL agent, but sometimes there are only a few scripts on the server that needs to execute the job, then deploying the agent at this time is a bit of a loss. We know that Taskctl supports any type of job extension, so we can consider using SSH remote connection to execute these small number of scripts. The following is the st

But then I encountered a tricky problem: When I log on to the other node by Using

Generally, a password is required each time you log on via ssh or use scp to copy files from a remote system before further processing. To omit the step of entering a password, you can use Shell script to solve the problem. However, you need to put the password manually entered in the script file as an explicit code. Using the key configuration file, OpenSSH can be an intermediate step for password verification omitted during
