1.3 Comparison

Remote - SSH

Remote - Containers

Remote - WSL

2 - Remote - SSH

Documentation： https://code.visualstudio.com/docs/remote/ssh

2.1 Preparation

Extension

SSH

• 远程主机已安装ssh-server
• 本地主机已安装ssh-client

2.2 Configuration

点击界面左下角图标，弹出远程开发命令面板

Remote-SSH: Connect to Host... :
可以直接输入主机地址进行连接，相关配置不会添加到 SSH 配置文件中

也可以选择 Add New SSH Host...，输入完整的ssh指令(支持附加额外的 SSH 参数)，相关配置会自动添加到 SSH 配置文件中

• Remote-SSH: Open Configuration File...：选取 SSH 配置文件并打开，自定义配置文件
• Remote-SSH: Getting Started...：会打开Getting Started 页面 https://code.visualstudio.com/docs/remote/ssh#_getting-started

2.3 Sample - Remote-SSH: Connect to Host

直接输入SSH信息并执行连接

选择目标主机的系统类型

输入密码

连接成功

查看信息

在目标主机可以查看到已经自动部署了 Remote Server，路径为 ~/.vscode-server/

2.4 Sample - Remote-SSH: Open Configuration File

2.4.1 Add and configure

输入连接信息

选择将连接信息存放在哪个配置文件

提示已添加主机

选择主机，点击鼠标右键选择连接方式

连接成功

2.4.2 Configuration change

• 在命令面板中，Remote-SSH: Open Configuration File...：选取 SSH 配置文件并打开，自定义配置文件
• 通过远程资源连接器
  
  可以查看和修改相应的配置信息，例如，添加端口信息 Port 22，指定秘钥文件 IdentityFile ~/.ssh/id_rsa.pub
  

2.5 Login without password

将本地生成的公钥添加到目标主机的 ~/.ssh/authorized_keys, 此后登录就不用输密码。

GuowangLi@CHN-L-GuowangLi /c/Projects
λ ls -l ~/.ssh/id_rsa.pub
-rw-r--r-- 1 GuowangLi 1049089 579 Apr 27 18:22 /c/Users/guowangli/.ssh/id_rsa.pub
GuowangLi@CHN-L-GuowangLi /c/Projects
λ ssh-copy-id root@192.168.56.200
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/c/Users/guowangli/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.56.200‘s password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh ‘root@192.168.56.200‘"
and check to make sure that only the key(s) you wanted were added.

GuowangLi@CHN-L-GuowangLi /c/Projects

2.6 Extension

给远程环境安装插件，对本机的VS Code没有影响。
插件在远端提供功能，比如代码审查、自动补齐等等，而这所有的一切就像在本地操作一样，对文件的更改也是直接操作的远程环境中的文件。

Note：需要以非root用户来进行Remote SSH连接。否则无法在SSH远程环境无安装扩展

选择容器

将会在对应的容器启动远程环境, 终端也将变成容器中的终端

3.5 Some configureations

官方示例中，涉及 .devcontainer.json 和 Dockerfile 两个文件

- .devcontainer :              开发环境配置目录
  - devcontainer.json :        环境配置文件，定义容器运行时的配置
  - Dockerfile :               环境的Docker镜像生成文件
- .vscode :                    vscode使用的配置文件（容器端使用）
  - launch.json :              debuger 配置文件（容器端使用）

Documentation： https://code.visualstudio.com/docs/remote/wsl

适用于 Linux 的 Windows 子系统文档

• https://docs.microsoft.com/en-us/windows/wsl/
• https://docs.microsoft.com/zh-cn/windows/wsl/

5 - Troubleshooting

TS-1

Description

Solution
https://docs.docker.com/engine/install/linux-postinstall/

To create the docker group and add your user:

Create the docker group.
    $ sudo groupadd docker

Add your user to the docker group.
    $ sudo usermod -aG docker $USER

Log out and log back in so that your group membership is re-evaluated.
    If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.
    On Linux, you can also run the following command to activate the changes to groups:
    $ newgrp docker 

Verify that you can run docker commands without sudo.
    $ docker run hello-world

TS-2

Description

Solution
为普通用户添加sudo命令的权限

# 1.切换到root用户，添加sudo文件的写权限
chmod u+w /etc/sudoers

# 2.编辑sudoers文件，在 root ALL=(ALL) ALL  一行下面添加 <user-name> ALL=(ALL) ALL    （允许<user-name>执行sudo命令， 但需要输入密码）
user    ALL=(ALL)    ALL                             # 允许用户user执行sudo命令(需要输入密码)
%usergroup   ALL=(ALL)    ALL                        # 允许用户组usergroup里的用户执行sudo命令(需要输入密码)
user    ALL=(ALL)    NOPASSWD: ALL                   # 允许用户user执行sudo命令,并且不输入密码
%usergroup   ALL=(ALL)    NOPASSWD: ALL              # 允许用户组usergroup里的用户执行sudo命令,并且不输入密码

# 3.撤销sudoers文件写权限
chmod u-w /etc/sudoers
