jupyter安装配置（Virtualbox运行）

python3 -m pip install --upgrade pip

python3 -m pip install jupyter

运行：
jupyter notebook

如果jupyter是运行在virtualbox虚拟机里面，那么可以设置virtualbox允许主机访问：
由于virtualbox设置成了NAT网络连接，因此需要通过端口转发的方式，允许宿主机器访问。
jupyter server的默认端口是8888，可以在virtualbox上设置端口转发如下：

jupyter安装配置（Virtualbox运行）

设置完以后最好重启一下virtualbox，保证生效。这样在宿主机可以通过http://127.0.0.1:9090 访问

另外，jupyter可以按如下方式配置：
如果还没有配置文件，可以通过jupyter notebook --generate-config 生成.jupyter目录，里面会生成jupyter_notebook_config.py，
可以定制自己需要的配置，例如：

# Local IP addresses (such as 127.0.0.1 and ::1) are allowed as local, along
# with hostnames configured in local_hostnames.
c.NotebookApp.allow_remote_access = True

## The IP address the notebook server will listen on.
(0.0.0.0即监听所有网卡IP)
c.NotebookApp.ip = '0.0.0.0'

## The directory to use for notebooks and kernels.（设置工作目录）
c.NotebookApp.notebook_dir = '/home/xxx/jupyter'

## Whether to open in a browser after starting. The specific browser used is
# platform dependent and determined by the python standard library `webbrowser`
# module, unless it is overridden using the --browser (NotebookApp.browser)
# configuration option.
c.NotebookApp.open_browser = False

## Token used for authenticating first-time connections to the server.
#
# When no password is enabled, the default is to generate a new, random token.
#
# Setting to an empty string disables authentication altogether, which is NOT
# RECOMMENDED.
#c.NotebookApp.token = '<generated>'
c.NotebookApp.token = ''
