python3.6 安装

1. 更新软件库

   yum update
   

   yum upgrade
   

2. 安装相关依赖工具

   yum groupinstall 'Development Tools'
   

   yum install -y ncurses-libs zlib-devel mysql-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
   

3. 下载安装python 3.6.5

   cd /usr/local
   

   wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
   

   tar -xf Python-3.6.5.tar.xz
   

   mkdir python3
   

   mv Python-3.6.5 python3
   

   cd python3/Python-3.6.5
   

   --prefix: 将make后python3.6的所有资源文件都放在/usr/local/python3目录下。

   ./configure --prefix=/usr/local/python3 --enable-optimizations
   

   make
   

   make altinstall
   

4. 配置新的python

   mv /usr/bin/python /usr/bin/python_old
   

   修改软连接

   ln -s /usr/local/python3/bin/python3.6 /usr/bin/python
   

   ln -s /usr/local/python3/bin/pip3.6 /usr/bin/pip
   

5. 修改yum文件的头指定引用python2

   vi /usr/bin/yum
   

   改成#!/usr/bin/python2

6. 检查是否安装配置好python3.6

   python
   

   pip -V
