centos 6.4 python升级到2.7.11

centos6.4默认安装的是python 2.6.6，现在要升级python升级到2.7.x，到官网下载最新版本，我下载时最新版本是2.7.11，地址如下：https://www.python.org/downloads/release/python-2711/

yum install readline-devel -y  #安装这个包是为了解决python交互模式使用键盘上的方向键乱码的问题

tar -xzvf Python-2.7.11.tgz

cd Python-2.7.11

./configure --prefix=/usr/local/python2.7.11

make

make install

mv /usr/bin/python /usr/bin/python2.6.6

ln -s /usr/local/pyton2.7.11/bin/pyton /usr/bin/python   #修改默认的python版本

#安装easy_install

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

#安装pip

east_install  pip

#我之前已安装过pip和easy_install，将新安装的pip和easy_install软链接一下

mv /usr/bin/easy_install /usr/bin/easy_install2.6.6

ln -s /usr/local/python2.7.11/bin/easy_install /usr/bin/easy_install

mv /usr/bin/pip /usr/bin/pip2.6.6

ln -s /usr/local/python2.7.11/bin/pip /usr/bin/pip

sed -i 's/python/python2.6.6/g' /usr/bin/yum    #修改yum使用的python版本
