阿里云搭建JupyterLab服务教程

安装Anaconda

先下载Anaconda 包

[root@iZwz9aoyyban4v42tgyml2Z ~]# mkdir anaconda
[root@iZwz9aoyyban4v42tgyml2Z ~]# cd anaconda/
[root@iZwz9aoyyban4v42tgyml2Z anaconda]# yum -y install wget
[root@iZwz9aoyyban4v42tgyml2Z anaconda]# wget https://repo.anaconda.com/archive/Anaconda3-2020.11-Linux-x86_64.sh

安装

[root@iZwz9aoyyban4v42tgyml2Z anaconda]# du -sh ./
529M    ./
# 验证anaconda
[root@iZwz9aoyyban4v42tgyml2Z anaconda]# md5sum Anaconda3-2020.11-Linux-x86_64.sh
4cd48ef23a075e8555a8b6d0a8c4bae2  Anaconda3-2020.11-Linux-x86_64.sh
[root@iZwz9aoyyban4v42tgyml2Z anaconda]#
[root@iZwz9aoyyban4v42tgyml2Z anaconda]# bash Anaconda3-2020.11-Linux-x86_64.sh

配置环境变量

# 进入道anaconda3的根目录bin下
[root@iZwz9aoyyban4v42tgyml2Z bin]# pwd
/root/anaconda3/bin
[root@iZwz9aoyyban4v42tgyml2Z bin]# vim ~/.bashrc
You have new mail in /var/spool/mail/root

# 在.bashrc下添加以下内容：
# Anaconda
export PATH="/root/anaconda3/bin:$PATH"

[root@iZwz9aoyyban4v42tgyml2Z bin]# source ~/.bashrc
[root@iZwz9aoyyban4v42tgyml2Z bin]# conda -V
conda 4.9.2

复现环境

安装虚拟环境

1	[root@iZwz9aoyyban4v42tgyml2Z bin]# conda create -n jabari python=3.7

安装Jupyter Lab服务

配置密码

[root@iZwz9aoyyban4v42tgyml2Z bin]# pip install jupyter jupyterlab
# 进入到ipython配置密码

In [1]: from notebook.auth import passwd

In [2]: passwd()
Enter password:
Verify password:
# 复制下面的输出内容，后面配置登陆密码需要。
Out[2]: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

生成配置文件

[root@iZwz9aoyyban4v42tgyml2Z bin]# jupyter lab --generate-config
Writing default config to: /root/.jupyter/jupyter_notebook_config.py

修改配置文件

1	[root@iZwz9aoyyban4v42tgyml2Z bin]# vim /root/.jupyter/jupyter_notebook_config.py

# 将ip设置为*，意味允许任何IP访问
c.NotebookApp.ip = '*'
# 这里的密码就是上边我们生成的那一串
c.NotebookApp.password = u'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
# 服务器上并没有浏览器可以供Jupyter打开
c.NotebookApp.open_browser = False
# 监听端口设置为8888或其他自己喜欢的端口
c.NotebookApp.port = 6888
# 我们可以修改jupyter的工作目录，也可以保持原样不变，如果修改的话，要保证这一目录已存在
c.MappingKernelManager.root_dir = '/root/jupyter_run'
# 允许远程访问
c.NotebookApp.allow_remote_access = True
# 配置jupyter lab文件存放路径，随喜好修改
c.NotebookApp.notebook_dir = '/'

[root@iZwz9aoyyban4v42tgyml2Z ~]# mkdir /root/jupyter_run
[root@iZwz9aoyyban4v42tgyml2Z ~]# ls
anaconda3  anaconda_bak  jupyter_run  node_modules  package-lock.json

配置阿里云服务器的安全组规则

登陆阿里云服务器控制台，选择配置安全组规则；

进入后选择配置规则；

配置TCP给6888端口；

启动Jupyter服务测试

[root@iZwz9aoyyban4v42tgyml2Z bin]# jupyter lab --allow-root
[I 15:33:08.598 LabApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret
[W 15:33:08.791 LabApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.

[I 15:33:09.027 LabApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

配置JupyterLab后台运行

前面配置的jupyter lab服务只有在当前终端存在时才会保持运行，当关闭当前终端时，当前终端的服务进程就会被kill掉，这里需要使Jupyter Lab时刻保持运行。

[root@iZwz9aoyyban4v42tgyml2Z ~]# nohup jupyter lab --allow-root &
[1] 15760

# 查看后台进程，如果要kill掉该进程，可以使用`kill -9 15760(pid)`命令去杀掉服务
[root@iZwz9aoyyban4v42tgyml2Z ~]# ps -ef | grep -v grep | grep jupyter
root     15760 14926  1 15:38 pts/0    00:00:00 /root/anaconda3/bin/python3.8 /root/anaconda3/bin/jupyter-lab --allow-root

OK，配置成功，开始愉快的写代码吧！
