Today, I will show you how to achieve Linux host ssh password-less login. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.

# generate the public key (in the simplest way, use the following command to enter all the way) # after running, the id_rsa and id_ras.pub files will be generated in the $HOME/.ssh directory # rsa refers to the encryption algorithm ssh-keygen-t rsa# to copy the public key on the local machine to the host that needs to log in remotely from the local machine # the target host owns the local public key file, indicating that the local machine is trusted to the target host The reliable # copy command is simple as follows (it is best not to copy it manually, too much human operation means more errors) # this process requires entering the password of the target host because the public key file needs to be transferred over the network to ssh-copy-id-I root@targethost

Simple application scenarios:

Linux_hostA: {IP:192.168.1.12,user:admin} linux_hostB: {IP:192.168.1.145,user:admin}

Implement password-free access between AMagi B, and between AMagi An and BMagne B.

# generate the public key of host A [admin@192.168.1.12] ssh-keygen-t rsa#A can access A [admin @ 192.168.1.12] ssh-copy-id-I admin@localhost#A without password and access B [admin @ 192.168.1.12] ssh-copy-id-I admin@192.168.1.145# without password to generate the public key of host B [admin@192.168.1.145] ssh-keygen-t rsa # B can access B [admin @ 192.168.1.145] ssh-copy-id-I admin@localhost#B without password and A [admin @ 192.168.1.145] ssh-copy-id-I admin@192.168.1.12 without password

After the above steps, you will not need a password to log in to the target host through ssh admin@targethost

The above is how to achieve Linux host ssh password-free login of all the content, more and how to achieve Linux host ssh password-free login-related content can search the previous article or browse the following article to learn ha! I believe the editor will add more knowledge to you. I hope you can support it!
