1.安装git,github地址为https://github.com/pyenv/pyenv-installer/ yum install git -y
2.安装python编译依赖环境 yum -y install gcc make patch gdbm-devel openssl-devel sqlite-devel readline-devel zlib-devel bzip2-devel
3.创建python用户用于搭建pyenv python多版本管理环境 useradd python passwd python
4.安装pyenv环境 curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
5.在python用户的环境变量目录~/.bash_profile下添加环境变量 export PATH export PATH="/home/python/.pyenv/bin:$PATH" eval "$(pyenv init -)" eval "$(pyenv virtualenv-init -)"
6.python查看版本命令：python --version pyenv命令： pyenv install -l #列出所有能安装的包 pyenv help local #指定本地pyenv环境，其目录下所有子目录都会递归继承其属性 global #指定全局的环境 shell #指定当前会话 install #指定安装的版本 uninstall #卸载指定的安装环境包 rehash version #查看当前环境使用的pyenv版本 versions #查看所有的存在的pyenv版本，带*号的为当前的pyenv环境版本 which whence
7.virtualenv虚拟环境设置 [python@node1 python3.5.3]$ pyenv versions system * 3.5.3 (set by /home/python/python3.5.3/.python-version) 3.6.2 [python@node1 python3.5.3]$ pyenv virtualenv 3.5.3 3-5-3 #将3.5.3版本的python命名为3-5-3的别名 Requirement already satisfied: setuptools in /home/python/.pyenv /versions/3.5.3/envs/3-5-3/lib/python3.5/site-packages Requirement already satisfied: pip in /home/python/.pyenv/versions/3.5.3/envs/3-5-3/lib/python3.5/site-packages [python@node1 python3.5.3]$ pyenv versions system 3-5-3* 3.5.3 (set by /home/python/python3.5.3/.python-version) 3.5.3/envs/3-5-3 3.6.2 [python@node1 python3.5.3]$ pyenv local 3-5-3 #使用虚拟环境时前面多出了一个名称 (3-5-3) [python@node1 python3.5.3]$ pyenv version 3-5-3 (set by /home/python/python3.5.3/.python-version) (3-5-3) [python@node1 python3.5.3]$
8.安装ipython pip install ipython
9.安装Jupyter,基于web的交互式笔记本 pip install Jupyter jupyter notebook help jupyter notebook password #更改密码 jupyter notebook --ip=0.0.0.0 #定义所有IP都可以访问该网页http://IP:8888/
