Linux下安装Python2.7

Linux下安装Python2.7

---

CentOS6.8 中默认安装了Python2.6，但是很多应用需要使用Python2.7，于是要学会如何在Linux下安装Python2.7，这里记录一下，免得以后需要的时候，重新找资料琢磨。此处下载了Python2.7.15

1、下载Python2.7.15

================

$wget https://www.python.org/ftp/python/2.7.9/Python-2.7.15.tgz

2、解压安装包、编译、安装

=======================

$tar -xzf Python-2.7.15.tgz

$cd Python2.7.15

$./configure --prefix=/usr/local/Python2.7.15

$make

$make install

3、系统自带了Python2.6，因此需要让python命令指向python2.7

================================================

$ln -s /usr/local/Python2.7.15/bin/python /usr/bin/python2.7

$ln -s /usr/bin/python2.7 /usr/bin/python
