The following commands are all server-side operations unless they are bolded to indicate that they operate on the local computer

1 Install and log in remotely using ssh

Update software list

sudo apt-get update

Update local software

sudo apt-get upgrade

Install ssh service

sudo apt-get install openssh-server

Start ssh service

sudo /etc/init.d/ssh start

View local IP address

After the inet field is your IP address.

sudo ifconfig

remote login

Enter ssh @ in the local computer terminal

Here we assume that the username and IP address on the server are xiaoming and 192.168.1.1. Please replace them with your own automatically. I will not repeat them later.

ssh xiaoming@192.168.1.1

2 Set Remote Login Shortcuts

It is troublesome to enter the username and password every time you log in to the server, and the IP address is not easy to remember, so you can modify the.bashrc file to set the quick key for remote login.

Open the.bashrc configuration file using an editor on your local computer

sudo vi ~/.bashrc

Add the following at the end

alias server='ssh xiaoming@192.168.1.1'

Close the file and reload the configuration file by entering the following command on the command line

source ~/.bashrc

After entering server in the terminal, you can log in to the server remotely

3 Add public key authentication

Entering the password of the server every time you log in is cumbersome and not very secure. At this time, you can add public key authentication to avoid the trouble of entering passwords and improve security.

3.1 generate the key pair

Enter the following command on your local computer

ssh-keygen

will prompt you

Generating public/private rsa key pair.Enter file in which to save the key (/home/python/.ssh/id_rsa):

Enter directly to confirm

Next, the system will prompt you to set a password to ensure the security of the key. Generally, enter directly to confirm that the password is blank. In this way, you can avoid the trouble of entering the password when using the private key authentication.

Switch to Key Pair Directory

cd ~/.ssh/

At this point, you can see the generated private key id_rsa and public key id_rsa.pub in the ~/.ssh directory. Remember not to expose your private key id_rsa under any circumstances.

3.2 Copy public key to remote server

Enter the following command on your local computer

ssh-copy-id xiaoming@192.168.1.1

3.3 Done!

After completing the above configuration, you can type the following command from your local computer to ssh remotely log on to your server

server
