标签：提示 windows 服务器ip sha1 默认 verify chown another 代码
完整原文：https://hongwan.xyz/archives/
使用Jupyter可以在本地电脑直接新建和编辑linux服务器的代码，比如python和R,非常方便；
本机为：Win10
服务器：CentOS Linux release 7.3.1611
本人之前安装Anaconda自带了jupyter notebook，因此可以直接使用。如果没有，可通过以下命令安装：
pip install jupyter notebook
默认情况下，配置文件 ~/.jupyter/jupyter_notebook_config.py 并不存在，需要自行创建。
运行以下命令创建：
jupyter notebook --generate-config
若root用户执行以上命令会提示
Running as root it not recommended. Use --allow-root to bypass.
只需加上 --allow-root 选项即可
执行成功后提示以下信息：
Writing default config to: /home/username/.jupyter/jupyter_notebook_config.py
服务器端命令行输入:
jupyter notebook password
此时会提示输入密码及确认密码，密码设置完成后提示将生成的密码写入/home/username/.jupyter/jupyter_notebook_config.json，注意username视用户而定，会直接出现在提示信息中。
$ Jupyter notebook password
Enter password: ****
Verify password: ****
[NotebookPasswordApp] Wrote hashed password to /home/username/.jupyter/jupyter_notebook_config.json打开存储密码的json文件，可以看到：
"password": "sha1:8d076d7433e6:7f0ed1c8e081133cec66f78748b01d7e27bdfec3"
复制此密文
在/home/username/.jupyter/jupyter_notebook_config.py中找到以下行，修改为：
c.NotebookApp.ip='*' #允许访问的IP地址，设置为*代表允许任何客户端访问
c.NotebookApp.password = u'sha1:8d...刚才生成密码时复制的密文'
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
c.NotebookApp.allow_remote_access = True命令如下：
jupyter notebook
此时我遇到了两个问题
（1)root用户可直接启动，普通用户则报错：
[I 12:50:36.604 NotebookApp] 把notebook 服务cookie密码写入 /run/user/1000/jupyter/notebook_cookie_secret

socket.gaierror: [Errno -2] Name or service not known这是由于在很多教程中没有设置c.NotebookApp.allow_remote_access = True所致，设置好这项便解决了问题。
此时应该可以直接从本地浏览器直接访问http://address_of_remote(服务器ip地址):8888就可以看到jupyter的登陆界面。
第一次登陆要求输入账号和密码，账号为服务器端用户名，密码即为刚刚第二步中设置的密码，即可看到目录列表。
若第四步输入网址无法进入，提示可能是防火墙问题，此时可以通过ssh访问远程服务器，?在windows下通过xshell等工具访问远程服务器，可在会话中设置，选择属性-ssh-隧道，点击添加
侦听端口填写8000（端口号与设置的有关），目标端口默认是8888
设置完成后，再在服务器输入jupyter notebook，在windows本地输入localhost:8000就可以访问远程服务器上的jupyter了
将Jupyter代码转成py脚本
jupyter nbconvert --to script 你的脚本名.ipynb
要使用R需要先安装R内核
简单的方法：通过Anaconda安装R内核
conda install -c r r-essentials稍微麻烦的方法：手动安装R内核如果你不是用Anaconda，过程会有点复杂，首先，你需要从CRAN安装R。?
之后，启动R控制台，运行下面的语句：
install.packages(c('repr', 'IRdisplay', 'crayon', 'pbdZMQ', 'devtools'))
devtools::install_github('IRkernel/IRkernel')
IRkernel::installspec() # to register the kernel in the current R installation本文同步到博客：
