Tencent cloud webshell experience
2022-07-07 00:53:00 【Nyarime】
In the near future , Tencent cloud to WebShell The terminal has added many functions , The biggest highlight is WebShell Support files are uploaded and downloaded , It provides convenient file management functions for some entry-level users . This is based on the original lightweight application server “ One click login ” An upgrade of the function , Can be built-in through the instance SSH Key Do secret free login . Including the tips in the lower right corner when using, I think they are all done very well , Next, let's talk about WebShell Advantages and disadvantages .
Edited version
As a remote software , It's definitely impossible not to support the edited version .
In the eyes of browsers , This is the operation of copying and pasting text .
One click login
Used before “ One click login ” function , Log in by default lighthouse user . Users cannot execute some high authority instructions , But users can use "sudo su root" To switch to root account number . Simply speaking , One click login depends on the built-in key of the instance system (SSH Key ) Sign in , But locally SSH A copy of the tool configuration key login still needs to be saved , For users who have high security requirements and are too lazy to configure , Tencent cloud WebShell It has been provided when purchasing the server , Free from configuration and the key is only stored in Tencent cloud . There is no need to worry about the risk of key disclosure , It can also ensure remote anytime, anywhere . There is no need to install any SSH Tools , Just a browser !
Mobile adaptation
On wechat “ Tencent cloud assistant ” Small program , We can log in to the server in resource management . There is also the function of virtual keyboard , You can easily use a series of shortcut keys . Can quickly log in to the server in case of emergency , Simply maintain it . Such as my Minecraft The server crashed , I can use screen Back to my game server console , Then restart it or modify the configuration with instructions .
In the mobile experience , It's still free of installation SSH The trouble of tools . That means , I don't need to download it on my mobile phone or on a computer JuiceSSH / Termius etc. SSH Tools to maintain the server , It greatly improves the efficiency for users .
Obsessive compulsive disorder : Clear the screen
Some Xiaobai just entered Linux circle , Don't know how to use clear Command clear screen . For me , Always use clear Put the disorderly SSH Session empty , Compared with input 5 Letters plus carriage return , I might as well press the button in the upper left corner to clear the screen . Especially the instructions on the full screen after installing a pagoda panel , Some obsessive-compulsive disorder is still a little annoying , Even knock hard Windows Under the cls To no avail :
At this time, just click the clear screen button in the upper left corner to clear the screen , Click on the console and it will be much cleaner :
Individualization : Set up
Speaking of this little nut , Inside is right. WebShell Some definitions of style . At present, it is divided into three major projects : font size 、 Fonts and colors . What I perceive most is the font and color , After all, JetBrains typeface and GitHub Color matching , Which one? Coding Will not move ?
Text size
On some high-resolution screens , Show WebShell The font size of may be too small . At this time, we can appropriately adjust the text size , Let the font size on the screen to achieve their own satisfaction :
typeface
Some users may not like the default font , My personal feeling Default The font is a little thin , It even makes me feel uncomfortable .
And as a Java Developer , Long term use intellij IDEA Development projects , about JetBrains You have to be familiar with . I'm very glad that WebShell Integrated JetBrainsMono typeface , This is a very suitable font for code farmers ~ And it will make SSH The font in the conversation has become a lot smoother .
I've been watching it for a long time , It seems that when you see programming IDEA In crazy output , visually attractive + comfortable ~
Color matching
In color matching , I still prefer dark (Dark) Color matching , It's mainly staring at white. It feels a little dazzling , Daily use habits are mainly dark . And I was in GitHub This color is also used when temporarily modifying the code on :
In the use of vi When editing text , I can clearly locate the corresponding row and column and then edit . But I want to make a little comment here , Can it be integrated fish-shell The function of , For example, automatic suggestion , Code highlighting and other functions !
SFTP replace : File transfer
After introducing the setting function , Let's talk about the file upload and download function launched this time .
Upload
But I think WebShell A good thing to do is to be able to distinguish permissions , Upload to the server on the premise of ensuring security
We can put it in /home/lighthouse Next , Because this is lighthouse The default directory of the account , We have read and write permission . But in some restricted directories , Like the system /root And other places have no read-write permission , Therefore, you cannot upload . We can raise the right to root user , Reuse mv Command transfer file . This is both safe and convenient for file transfer , Effect on sftp Little difference .
Download the file
When you download the file , You also need to access writable directories . Then check the file to download .
But check multiple files before downloading , You need to allow multiple files to be downloaded in the browser first , Otherwise, you can only download one at a time
Then when downloading , There will be a list of downloaded files in the lower right corner , We just need to click on read ( Mail with forks )/ Delete one by one to clear these lists , Then the list will show the remaining tasks or no tasks
Then click "put away" to close
Simultaneous operation : Split screen
The new features of this update , Users can execute different commands at the same time
however , This thing seems to have a certain probability of interruption ... I don't know if it's the problem of Tencent intranet , In a word, this situation will appear after a few minutes of use , In the later stage, the official may improve the stability of the split screen function
Multi session window
In fact, the score screen of this function is early , I think split screen is designed to make it troublesome for tabs to switch back and forth .
If we say split screen function 2 One is not enough , I can even superimpose in the split screen :
How many can you create at most ? Judging from the current official restrictions , Split screen can be divided 4 individual , The conversation window can be opened 5 individual . So that is 20 One session :
But in theory , Users don't need so many session windows ( It's probably OK to use it for the whole job
Instance self-service detection
Finally, let's talk about this Instance self-service detection function , In official terms , It helps you understand the instance status , Find and solve problems to help you detect the instance performance 、 cost 、 The Internet 、 A tool for disk and other States :
In fact, as a little white , I think opening a server , It's over when the security group port is fully opened . The key is that I bought the worry free instance , Can't upgrade .
Even though the average utilization rate of my outgoing bandwidth exceeds 「90%」, It has become the so-called business bottleneck , It can only give you a suggestion , Can't help you upgrade .
I feel that this thing focuses on the Internet , Instance and hard disk ... It doesn't make sense , And Tencent cloud engineers also 7*24 Hours are serving us , I think if the configuration is not enough , There's still a squeeze
Conclusion
WebShell Although it provides a good data experience , However, it is still limited to Linux operating system . Perhaps in Windows On ,WebShell It's a good one VDI( Virtual desktop environment ) Solutions for , But no one except me will use lightweight as a cloud computer .
Secondly, the authority security is well done , Document management is also very simple and clear . And the master led in , Cultivation depends on individuals . Tencent cloud WebShell Just let you adapt Linux Introduction AIDS , It can do many things , Of course, it's cool . And the most important thing is to learn more by yourself Linux The operation of , Instead of relying on such visualization tools .
