Server installation jupyterab and remote login configuration

The first thing to be clear is jupyterlab Need to rely on jupyter-notebook, And the two were originally dependent on Anaconda, So it's best to use anaconda Environmental Science .（ Do not want to use Anaconda Environmental , You can search the installation method by yourself )

Sign in Linux The server :

ssh [email protected]

install Anaconda（ already installed , Skippable ）

About Anaconda The version and python Version correspondence , You can refer to my notes ：
anaconda Historical version download address and Anaconda Version and Python3 Version correspondence

Pay attention to the naming rules in the text .
This is installed by default jupyter, If not installed , Execute the following command ：

conda install -c anaconda jupyter

install jupyterlab

conda install -c conda-forge jupyterlab

Generate configuration files :

jupyter notebook --generate-config# The generated file is located at ：~/.jupyter/jupyter_notebook_config.py # The configuration file 

Set the password :

$ipython
In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password: ******
Verify password: ******
Out[2]: '************************************************'  # This is the key , Keep in mind 

Copy the key generated above , Configuration will use ,password Is the password you need to enter when logging in remotely , Also need to remember .
To configure jupyterlab Environmental Science :

#vim ~/.jupyter/jupyter_notebook_config.py
c.NotebookApp.ip = '*' #  Of your server IP Address , Usually static address 
c.NotebookApp.password = u'*****************************************' #  This is the secret key just to be saved 
c.NotebookApp.open_browser = False
c.NotebookApp.port = 8888    # port , You can specify 
c.NotebookApp.allow_remote_access = True

install Node.js

First download node.js, Address ：Node.js download
Download on demand , Download the corresponding schema , It's usually x64 Architecturally , As shown in the figure below ：

Decompress after downloading , It is best to put it in the directory where the program is installed , Then configure the environment （windows Open the environment variable and add it ）:

$vim ~/.bashrc
export PATH=/node path/bin:$PATH #  The extracted location 
source ~/.bashrc
$node -v #  Check node Environment configured successfully 
#  Output node Corresponding version 】
v16.13.1

start-up jupyter-lab

General startup jupyter It will keep running after , So you can put it in the background , May adopt screen To achieve , First create a file named jupyterlab The background of :

$screen -S jupyterlab

Then start jupyterlab:

$jupyter-lab

Finally according to the Ctrl+A+D Press the key combination to exit the background , and jupyter-lab Keep running

notes ： Here to install Node.js It's to make jupyter Display more friendly , Recommended installation .

Be careful ： If it's opening jupyter There are such errors in the service ： attributeerror: ‘extensionmanager’ object has no attribute ‘_extensions’, This is because nbclassic The version of is wrong , Execute the following command ：

pip install nbclassic=0.2.8

Then open the service to log in remotely .
