今天装了个jupyter notebook看能不能在浏览器里直接写代码，顺便写文档。linux不太会，python也是知道皮毛，所以不是太顺利。以下是中间处理的几个小问题。
环境 centos7 + python 2.7.5
用的是镜像自带的python。
[root@play-crm ~]# hostnamectl
。。。。
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-1127.el7.x86_64
Architecture: x86-64
[root@play-crm ~]# python --version
Python 2.7.5
中间遇到了几个坑，记录
错误1：安装工具太老了
Unknown distribution option: 'project_urls'
ERROR: Command errored out with exit status 1:

要升级pip或者setuptools: https://github.com/gevent/gevent/issues/1646
直接运行
pip install -U pip setuptools
错误2：启动报错 UnicodeDecodeError
[root@play-crm ~]# jupyter notebook
The Jupyter HTML Notebook.
这将启动一个基于tornado的HTML笔记本服务器，它提供一个html5/
javascript笔记本客户端。

使用中文字符集的系统上，python2.7转码会出错
In case any Chinese users would like any actually useful help with this issue, while you should upgrade to using Python 3 versions of Jupyter if possible, if you cannot upgrade for whatever reason: try setting the environment variable LANGUAGE=en_US so that Jupyter doesn't try to use its Chinese translation, which clearly doesn't work well on Python 2

修改系统的默认字符集成en_US.utf8
方法如下：https://www.osetc.com/en/centos-7-rhel-7-change-the-system-locale.html
- 确认系统语言环境
[root@play-crm ~]# locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=
- 改文件
vi /etc/locale.conf
内容改成
LANG=es_US.utf8
- 重启
reboot
jupyter notebook的启动参数
jupyter notebook --allow-root --password testjupyter --ip 192.168.3.179
- --allow-root 允许用root账号启动
如果你用root来启动，默认不允许，所以加参数 - --ip 默认只能用localhost访问
防火墙开端口8888
centos7提供firewall-cmd来设置防火墙，比较简单，两行搞定
参考：https://www.xmodulo.com/open-port-firewall-centos-rhel.html
$ sudo firewall-cmd --zone=public --add-port=8888/tcp --permanent
$ sudo firewall-cmd --reload
搞定收工
