Python升級（2.6.6升級到2.7.6）

• 安裝所需軟體包

[[email protected] ~]# yum install -y zlib zlib-devel bzip2 bzip2-devel bzip2-lib sqlite sqlite-devel ncurses-devel readline-devel patch

• 檢視當前python版本

[[email protected] python]# python -V
Python 2.6.6
[[email protected] python]#

• 安裝python 2.7.6

[[email protected] python]# tar -zxf Python-2.7.6.tgz
[[email protected] python]# cd Python-2.7.6
[[email protected] Python-2.7.6]# ./configure
[[email protected] Python-2.7.6]# make install

• 建立軟連結

[[email protected] Python-2.7.6]# mv /usr/bin/python /usr/bin/python2.6.6
[[email protected]
 
 Python-2.7.6]# ln -s /usr/local/bin/python2.7 /usr/bin/python

• 檢視當前Python版本

[[email protected] ~]# python -V
Python 2.7.6
[[email protected] ~]#

• 解決升級Python後yum無法使用的情況（修改/usr/bin/yum，將第一行改為/usr/bin/python2.6.6）

[[email protected] ~]# cp -a /usr/bin/yum{,.bak}
[[email protected] ~]# sed -i 's%^#!/usr/bin/python$%#!/usr/bin/python2.6.6%' /usr/bin/yum
