说明：最近看上了Jupyter Lab，比之前搭建的jupyter notebook体验更好，打算把他装在阿里云送的突发型2c4g服务器上，便于我写程序。

阿里云控制台

登陆阿里云控制台，选择centos7.7镜像，安装，开放安全组端口。

Xshell

安装python3

首先先更新系统

yum update -y

进入Xshell，准备安装python3
先安装必要环境

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make wget libffi-devel

备份现有的python2

cd /usr/bin
mv python python.bak
mv pip pip.bak

使用淘宝源下载并编译安装python3。具体可以看我之前写的文章

cd ~ && wget https://npm.taobao.org/mirrors/python/3.8.2/Python-3.8.2.tar.xz 
tar -xvJf Python-3.8.2.tar.xz
cd Python-3.8.2
#指定安装路径
./configure prefix=/usr/local/python3
#编译并安装
make && make install

做一条软连接，将python3指向python，pip3指向pip：

ln -s /usr/local/python3/bin/python3 /usr/bin/python
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

修改yum配置

vim /usr/bin/yum

按insert，把头部的 #! /usr/bin/python 修改为 #! /usr/bin/python2

同理修改urlgrabber-ext-down 文件，把头部的 #! /usr/bin/python 修改为 #! /usr/bin/python2

vim /usr/libexec/urlgrabber-ext-down

安装nodejs、npm和yarn

curl --silent --location https://rpm.nodesource.com/setup_12.x | bash -
sudo yum install -y nodejs
curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
sudo yum install -y yarn

安装jupyterlab

安装一些包

yum groupinstall "Development Tools" -y

升级pip并安装ipython和jupyter

pip install --upgrade pip
pip install ipython jupyterlab

ln -sv /usr/local/python3/bin/ipython /usr/bin/
ln -sv /usr/local/python3/bin/jupyter /usr/bin/

创建Jupyter配置文件，生成在/root/.jupyter/jupyter_notebook_config.py

cd ~
jupyter lab --generate-config

开ipython，生成sha1的密码，并保存输出的sha1.如下：

ipython
from notebook.auth import passwd
passwd()
#Enter password
#output sha1:b19ff9adaa17:d2134ea473aa63718336ed0fb297f8bf44a9c783.
exit()

编辑配置文件

vim /root/.jupyter/jupyter_notebook_config.py

找个地方插入，

c.NotebookApp.password = 'sha1:<your-sha1-hash-value>'
c.NotebookApp.port = 8000
c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False
c.NotebookApp.allow_root = True
c.NotebookApp.allow_remote_access = True
c.NotebookApp.notebook_dir = '/root/lab'

创建文件夹

mkdir /root/lab
mkdir /root/build

安装R语言内核（可选）

yum -y install epel-release
yum -y install R 
yum -y install curl 
yum -y install libcurl libcurl-devel 
yum -y install libxml2 libxml2-devel 
R
install.packages(c('repr', 'IRdisplay', 'evaluate', 'crayon', 'pbdZMQ', 'devtools', 'uuid', 'digest'))
install.packages("IRkernel")
IRkernel::installspec(user = FALSE)

安装julia语言内核（可选）

mkdir /usr/local/julia
cd /usr/local/julia
wget https://mirrors.ustc.edu.cn/julia/releases/v1.4/julia-1.4.1-linux-x86_64.tar.gz
tar -zxvf julia-1.4.1-linux-x86_64.tar.gz
mv julia-1.4.1/* /usr/local/julia
rm -rf  julia-1.4.1
ln -s /usr/local/julia/bin/julia /usr/bin/julia

进入julia

julia
]
add IJulia
exit()

安装JavaScript内核（可选）

npm install -g ijavascript
ijsinstall --spec-path=full

安装插件（可选）

pip install ipyleaflet
jupyter nbextension enable --py --sys-prefix ipyleaflet
pip install bqplot
jupyter nbextension enable --py --sys-prefix bqplot
pip install pythreejs
jupyter nbextension enable --py --sys-prefix pythreejs
pip install ipyvolume
jupyter nbextension enable --py --sys-prefix ipyvolume
pip install k3d
jupyter nbextension enable --py --sys-prefix k3d
pip install gmaps
jupyter nbextension enable --py --sys-prefix gmaps
pip install nglview
jupyter nbextension enable --py --sys-prefix nglview
jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-leaflet bqplot jupyter-threejs ipyvolume jupyter-matplotlib
jupyter labextension install jupyterlab-drawio @jupyterlab/toc @jupyterlab/latex @jupyterlab/shortcutui

后台启动

nohup jupyter lab > jupyterlab.log &

删除内核

jupyter kernelspec list
jupyter kernelspec remove 内核名

卸载插件

jupyter labextension list
jupyter labextension uninstall 插件名
