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-devel3.创建python用户用于搭建pyenv专用于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 | bash5.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

[[email protected] python3.5.3]$ pyenv versions
system
* 3.5.3 (set by /home/python/python3.5.3/.python-version)
3.6.2
[[email protected] 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
