Centos下Python整体环境安装

python 2.6升级 2.7
1.下载python2.7.x

wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz

2.解压并编译安装

tar -zxvf Python-2.7.6.tgz && cd Python-2.7.6 && ./configure && make all && make install && make clean && make distclean

3.检查安装

/usr/local/bin/python2.7 -V

4.建立软连接，使用系统默认的python指向

mv /usr/bin/python /usr/bin/python2.6.6ln -s /usr/local/bin/python2.7 /usr/bin/python

5.检查

python -V

6.用yum需注意

解决系统 Python 软链接指向 Python2.7 版本后，因为yum是不兼容 Python 2.7的，所以yum不能正常工作，我们需要指定 yum 的Python版本vim /usr/bin/yum 将头部#!/usr/bin/python 改成#!/usr/bin/python2.6.6(刚刚备份的)

安装pip
1.下载get-pip.py

wget https://bootstrap.pypa.io/get-pip.py

2.执行安装pip

yum install setuptool zlib* -ypython get-pip.py

安装GCC环境，与mysql驱动

yum install -y mysql-devel python-devel python-setuptoolsyum install -y gcc yum install -y gcc gcc-c++ pip install MySQL-python

安装pandas等环境

yum -y install blas blas-devel lapack-devel lapackyum -y install seaborn scipyyum -y install freetype freetype-devel libpng libpng-devel然后用豆瓣的pypi源要比官方的快很多pip install matplotlib -i http://pypi.douban.com/simple --trusted-host pypi.douban.compip install numpy -i http://pypi.douban.com/simple --trusted-host pypi.douban.compip install pandas -i http://pypi.douban.com/simple --trusted-host pypi.douban.compip install seaborn scipy
