# 1.生成配置文件
默认情况下，配置文件 ~/.jupyter/jupyter_notebook_config.py 并不存在，需要自行创建。使用下列命令生成配置文件：
jupyter notebook --generate-config
如果是 root 用户执行上面的命令，会发生一个问题：
Running as root it not recommended. Use --allow-root to bypass.
提示信息很明显，root 用户执行时需要加上 --allow-root 选项。
jupyter notebook --generate-config --allow-config
执行成功后，会出现下面的信息：
Writing default config to: /root/.jupyter/jupyter_notebook_config.py
当然Windows操作系统的话应该是在
Writing default config to: C:\Users\you\.jupyter\jupyter_notebook_config.py
# 2. 生成密码
# 自动生成
从 jupyter notebook 5.0 版本开始，提供了一个命令来设置密码：jupyter notebook password，生成的密码存储在 jupyter_notebook_config.json
$ jupyter notebook password
Enter password: ****
Verify password: ****
[NotebookPasswordApp] Wrote hashed password to /Users/you/.jupyter/jupyter_notebook_config.json
# 手动生成
除了使用提供的命令，也可以通过手动安装，我是使用的手动安装，因为jupyter notebook password 出来一堆内容，没耐心看。打开 ipython 执行下面内容：
In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password:
Verify password:
Out[2]: 'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'
sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed 这一串就是要在 jupyter_notebook_config.py 添加的密码
c.NotebookApp.password = u'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'
# 3.配置远程访问
在 jupyter_notebook_config.py 中找到下面的行，取消注释并修改，或直接添加如下内容
c.NotebookApp.ip='*'
c.NotebookApp.password = u'sha:ce...刚才复制的那个密文'
c.NotebookApp.open_browser = False
c.NotebookApp.port =8888 #可自行指定一个端口, 访问时使用该端口
以上设置完以后就可以在服务器上启动 jupyter notebook，jupyter notebook, root 用户使用 jupyter notebook --allow-root。打开 IP:指定的端口, 输入密码就可以访问了
需要注意的是不能在隐藏目录 (以 . 开头的目录)下启动 jupyter notebook, 否则无法正常访问文件

## Forces users to use a password for the Notebook server. This is useful in a

## Shut down the server after N seconds with no kernels or terminals running and
# no activity. This can be used together with culling idle kernels
# (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when

# otherwise.
# Default: {}
# c.NotebookApp.terminado_settings = {}
## Set to False to disable terminals.
#
# This does *not* make the notebook server more secure by itself. Anything the

#
# Terminals may also be automatically disabled if the terminado package is not
# available.
# Default: True
# c.NotebookApp.terminals_enabled = True
## Token used for authenticating first-time connections to the server.
#
# The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set
# directly with the JUPYTER_TOKEN environment variable.
#
# When no password is enabled, the default is to generate a new, random token.

# Default: False
# c.NotebookApp.trust_xheaders = False
## Disable launching browser by redirect file
#
# For versions of notebook > 5.7.2, a security feature measure was added that
# prevented the authentication token used to launch the browser from being
# visible. This feature makes it difficult for other users on a multi-user
# system from running code in your Jupyter session as you.
#
# However, some environments (like Windows Subsystem for Linux (WSL) and
# Chromebooks), launching a browser using a redirect file can lead the browser
# failing to load. This is because of the difference in file structures/paths
# between the runtime and the browser.

# Disabling this setting to False will disable this behavior, allowing the
# browser to launch by using a URL and visible token (as before).
# Default: True
# c.NotebookApp.use_redirect_file = True
## DEPRECATED, use tornado_settings
# Default: {}
# c.NotebookApp.webapp_settings = {}
## Specify Where to open the notebook on startup. This is the `new` argument

# guaranteed, but depends on browser support. Valid values are:
#
# - 2 opens a new tab,
# - 1 opens a new window,

#
# See the `webbrowser.open` documentation for details.
# Default: 2
# c.NotebookApp.webbrowser_open_new = 2
## Set the tornado compression options for websocket connections.
#
# This value will be returned from
# :meth:`WebSocketHandler.get_compression_options`. None (default) will disable

# Default: None
# c.NotebookApp.websocket_compression_options = None

# Session(Configurable) configuration
#------------------------------------------------------------------------------
## Object for handling serialization and sending of messages.
#
# The Session object handles building messages and sending them with ZMQ sockets
# or ZMQStream objects. Objects can communicate with each other over the
# network via Session objects, and only need to work with the dict-based IPython
# message spec. The Session will handle serialization/deserialization, security,
# and metadata.
#
# Sessions support configurable serialization via packer/unpacker traits, and
# signing with HMAC digests via the key/keyfile traits.
#
# Parameters ----------
#
# debug : bool
# whether to trigger extra debugging statements
# packer/unpacker : str : 'json', 'pickle' or import_string
# importstrings for methods to serialize message parts. If just
# 'json' or 'pickle', predefined JSON and pickle packers will be used.
# Otherwise, the entire importstring must be used.
#
# The functions must accept at least valid JSON input, and output *bytes*.
#
# For example, to use msgpack:
# packer = 'msgpack.packb', unpacker='msgpack.unpackb'
# pack/unpack : callables
# You can also set the pack/unpack callables for serialization directly.
