Use VSCode's Remote-SSH to connect to Linux for remote development

Install Remote-SSH and configure it

First open your VSCode, find Extensions, search for Remote, download the Remote-Development plug-in, and other Remote plug-ins will be automatically installed, including Remote-SSH:

Go to settings, search for ssh , find and select the ShowLoginTerminal option in Remote-SSH in Extensions, because when connecting, the terminal will ask you to enter yes or password, etc.

Next, you need to configure your Linux server address information. Press CTRL+SHIFT+P , search for ssh , and find the Open Configuration File option.

Then enter your address information:

Linux installation and configuration of OpenSSH-Server

Ubuntu

// Uninstall first sudo apt-get remove openssh-server
//Install sudo apt-get install openssh-server

//Restart the sshd service sudo service ssh --full-restart
//Automatically start sudo systemctl enable ssh

CentOS

//Install yum install -y openssl openssh-server

//Restart the sshd service systemctl restart sshd.service

//Automatically start systemctl enable sshd

Editing the Configuration File

Backing up configuration files

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.backup

Editing the Configuration File

sudo vim /etc/ssh/sshd_config

Add the following configuration to the configuration file:

Ports can be customized

Login with password

After saving, restart the sshd server. The restart command is given above.

Connecting to SSH using a password

Find the Linux server you configured:

Enter the password and press Enter:

Then open the folder and start writing code:

Use CTRL + SHIFT + ~ to call out the terminal, then you can operate commands in the terminal and open files to write code.

Log in without password using key

Client Configuration

Make sure that ssh is installed on your local Windows operating system.
Generate an SSH key pair:

ssh-keygen -t rsa -b 4096

(-b 4096 means the length of the generated RSA key pair is 4096 bits) After entering this command, we will be asked to specify the directory where the key file will be generated. You can press Enter to skip this step. The generated directory is c:\user\WINDSUN\.ssh Two files, id-rsa and id-rsa.pub are generated. The first one is the private key file, and the second one is the public key file. The user name is your own computer user name.

Server-side configuration

Check whether the ssh service is started

netstat -ntlp | grep ssh

Modify the configuration file

vim /etc/ssh/sshd_config

The most important thing here is that we need to configure PubkeyAuthentication to yes to allow login using key-based authentication.
Finally, upload the client's public key id-rsa.pub file to the .ssh folder of the corresponding user's root directory, enter .ssh and copy the contents of the public key to the authorized_keys file

cp id_rsa.pub authorized_keys

Then set the permissions for the corresponding files

chmod 700 .ssh
chmod 600 .ssh/authorized_keys

VS Remote-SSH plugin configuration

Set up the Remote - SSH plugin configuration file for vscode:

Host Aliyun
  HostName XXXX
  User XXX
  IdentityFile C:\Users\WINDSUN\.ssh\id_rsa

Problems encountered

If a pipeline error is reported, it may be the following problem

• There is a problem with the ssh configuration of your Linux server. Test whether the problem is solved by modifying the configuration.
• Delete the '.vscode-server' directory created on the server. This is a hidden directory created in your home directory (you can use "ls -la" to show all the files I believe). It could be that some incorrect data is being cached there, so deleting the directory will make your situation much cleaner. After deleting, you can try to reconnect via remote-ssh on vscode.
• If it still doesn't work, you can try to use FTP to upload the local public key to Linux again, then copy it to the authorized_keys file, set permissions, restart the SSH server, and reconnect

Precautions

When you use the public key to connect to Linux for the first time, you may be asked to enter a password. After the connection is completed, a file known_hosts will be generated in your user's .ssh directory. This directory also contains the public and private keys id-rsa.pub and id-rsa. Then upload the public key to the server, repeat the above copy to .ssh/authorized_keys, reset the permissions, and try to connect to Linux again. You don't need to enter a password again.
