python3 安装
##yum 安装python
yum install -y python36
##可以添加软连接 此命令不对，应该是绝对路径 ln -s python3.6 python3
##备份原来得python命令，应该为软连接
mv /usr/bin/python /usr/bin/python.bak
##重定向python到python3
ln -s /usr/bin/python3.6 /usr/bin/python
##修改yum使用得python 命令，yum 会使用python2
把#! /usr/bin/python修改为#! /usr/bin/python2
sed -i 's@/usr/bin/python@/usr/bin/python2@' /usr/bin/yum
把#! /usr/bin/python 修改为#! /usr/bin/python2
sed -i 's@/usr/bin/python@/usr/bin/python2@' /usr/libexec/urlgrabber-ext-down
##安装pip3
1. 安装easy_install
注意安装与以上python版本相同的setuptools
yum install -y python36-setuptools
2. 安装pip
安装之后，pip3位于/usr/local/bin目录下
python -V
CentOS 7编译安装python3
参考：https://blog.csdn.net/lovefengruoqing/article/details/79284573
#python 在哪
[root@root ~]# whereis python
# cd /usr/bin/
# ll python*
##下载编译python3的工具依赖环境
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
3.默认的，centos7也没有安装pip
#运行这个命令添加epel扩展源
yum -y install epel-release
#安装pip
yum install python-pip
4.用pip装wget
pip install wget
5.用wget下载python3的源码包下载地址https://www.python.org/downloads/
wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tar.xz
6.编译python3源码包
#解压
xz -d Python-3.6.4.tar.xz
tar -xfC Python-3.6.4.tar
#进入解压后的目录，依次执行下面命令进行手动编译
./configure prefix=/usr/local/python3
make && make install
7.添加软链接
#将原来的链接备份
mv /usr/bin/python /usr/bin/python.bak
#添加python3的软链接
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python
#测试是否安装成功了
python -V
8.更改yum配置，因为其要用到python2才能执行，否则会导致yum不能正常使用
vi /usr/bin/yum
把#! /usr/bin/python修改为#! /usr/bin/python2
vi /usr/libexec/urlgrabber-ext-down
把#! /usr/bin/python 修改为#! /usr/bin/python2
##将命令添加到
jupyter 安装
2 wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-5.3.1-Linux-x86_64.sh
7 yum install bzip2
8 sh Anaconda3-5.3.1-Linux-x86_64.sh -u
12 cd anaconda3/
17 cd /root/anaconda3/
24 bin/jupyter-notebook --generate-config
25 cat /root/.jupyter/jupyter_notebook_config.py
26 vi /root/.jupyter/jupyter_notebook_config.py
30 export PATH=/root/anaconda3/bin:$PATH
31 ipython
32 vim ~/.jupyter/jupyter_notebook_config.py

c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False

c.NotebookApp.port = 8888
jupyter 起服务脚本
mkdir /data
vi python_service.py
#!/usr/bin/env python
# encoding: utf-8
import subprocess
import sys
subprocess.call("cd /", shell=True)
subprocess.call("jupyter lab --ip=0.0.0.0 --no-browser --allow-root --NotebookApp.token='jupyterAdmin' --notebook-dir=/data", shell=True)
