CentOS 6.7（系统自带Python2.6.6）升级python 2.7并安装pip

一、升级python为2.7

1.安装升级相应的软件包

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

2.下载python 2.7  的源码包并解压到相关目录

cd /root/Download/
wget http://mirrors.sohu.com/python/2.7.6/Python-2.7.6.tgz
tar zxf Python-2.7.6.tgz -C /usr/local/src/

3.安装

cd /usr/local/src/Python-2.7.6/  
./configure --prefix=/usr/local/python2.7
make && make install

4.配置

mv /usr/bin/python /usr/bin/python.bak  
ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python

5.查看版本

python -V

显示：Python 2.7.6

二 安装pip

2.1 setuptools的安装

wget --no-check-certificat  https://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz
tar zxf setuptools-2.0.tar.gz
cd setuptools-2.0
python setup.py install

2.2 pip的安装

wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificate
tar -xzvf pip-1.3.1.tar.gz
cd pip-1.3.1
python setup.py install

2.3 修改环境变量

vi /etc/prifile

在最后的export PATH一行的最后面添加:/usr/local/python2.7/bin 如下图：

保存退出
让刚刚设置的环境变量生效，运行

source /etc/profile

检查

安装完成
