下载Python3.5.2源码:https://www.python.org/downloads/release/python-352/
解压到 /opt目录下
tar zxvf Python-3.5.2.tgz -C /opt/
改名为python352:
cd /opt
mv Python-3.5.2 python352
创建安装目录:mkdir /usr/local/python3.5.2
查看是否安装 rpm -qa | grep openssl-devel
没有就安装
yum install openssl-devel
检查编译环境:./configure --prefix=/usr/local/python3.5.2
编译:make
生成安装包:make install
配置环境:
a.先修改老的连接,执行:mv /usr/bin/python /usr/bin/python_bak
b.建立python新连接: ln -s /usr/local/python3.5.2/bin/python3.5 /usr/bin/python
b.建立pip新连接: ln -s /usr/local/python3.5.2/bin/pip3.5 /usr/bin/pip
大功告成
查询python版本,执行:python
显示:
Python 3.5.2 (default, Dec 9 2016, 09:15:55)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
修改 yum程序保证其可用
vi /usr/bin/yum
将: 将首行#!/usr/bin/python改成#!/usr/bin/python2.7 或修改成/usr/bin/python_bak 即可
重启后检验一下:reboot
