环境:

    Centos6.7

    python 2.7.9


1,安装Centos操作系统:

  yum update

      yum -y  install vim wget 

2,安装python2.7.9

CentOS 6.6自带的是Python 2.6.6,而编译llvm需要Python 2.7以上。yum中最新的也是Python 2.6.6,只能下载Python 2.7.9的源代码自己编译安装。

1)安装devtoolset

yum groupinstall "Development tools"

2)安装编译Python需要的包包

yum -y install zlib-devel
yum -y install bzip2-devel
yum -y install openssl-devel
yum -y install ncurses-devel
yum -y install sqlite-devel

3)下载并解压Python 2.7.9的源代码

cd /opt
wget --no-check-certificate https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
tar xf Python-2.7.9.tar.xz
cd Python-2.7.9

4)编译与安装Python 2.7.9

./configure --prefix=/usr/local
make && make install

5)将python命令指向Python 2.7.9

mv /usr/local/bin/python /usr/local/bin/python2.6
ln -s /usr/local/bin/python2.7 /usr/local/bin/python

6)检查Python版本 python -V
