[VsCode] 藉由 Remote-SSH 連接 Linux
結論

一、前言

在測試Oracle Cloud的時候有提供免費方案可以架設VPS，剛好藉此機會來玩一下透過VsCode要如何SSH遠端，單純使用SSH遠端的方式有很多種，之前在工作中往往都是透過Putty＋WinSCP來完成相關需求，這次只是單純想要試試不同的工具看看有沒有新的發現。

二、基本設定

SSH KEY

可以使用PuTTYgen協助生產，至於這邊部分因為我們是使用OracleCloud上的主機，這邊在OCI上面自己生產，位子如下圖：

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

VsCode

這邊我們是使用Remote - SSH套件，直接在VsCode搜尋後安裝即可

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

安裝完成後UI上面會多了一個功能(圖#1)，這邊我們直接點擊功能業內的+號來新增連線

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

點擊後會跳出視窗，這邊輸入對應的使用者和連線位置之後即可

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

這時會跑出要你選擇SSH Config的路徑，這邊我們直接選預設路徑就好了

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

完成後UI會跳出所設定好的連線

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

基本上到這一步算是基本的建立都已經完成了，接下來要來進行設定私鑰

Pirvate Key

在連線中我們想要使用私鑰進行認證這邊提供兩種方式

.ssh

將私鑰直接放置對應的位置即可，在連線時會自動檢查

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

SSH config

我們也可以真對SSH config做些設定，這邊我們點選齒輪後續依樣使用預設的路徑(如下圖)

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

之後會打開一份文件即是SSH的設定檔

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

這邊我們增加了一個IdentityFile的設定用來直接指定私鑰

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

相關設定的參考可參考網址 ssh_config

三、連線操作

要連線時可以對該設定點選右鍵或點選右方的小圖即可

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

連線成功後左下角也可以看到相關資訊

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

透過工具也可以針對資料夾作連動，在連線狀態下我們前往資料夾頁面，並點選開啟資料夾

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

之後畫面會跳出路徑設定，這邊選擇想要操作的資料夾即可

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

確定後VsCode就會顯示內部的資料夾

Image Not Showing Possible Reasons

The image file may be corrupted
The server hosting the image is unavailable
The image path is incorrect
The image format is not supported

結論

這次正好有時間來玩一下不同的工作使用SSH連接，整體測試下來還算蠻滿意的，以往會需要Putty＋WinSCP來做切換才可完成任務，但在之後工作上或許可以在VsCode就完成，對我來說算是不錯的選擇。
