在Linux CentOS 6.8上安装Python 2.7.12

CentOS 6.8自带的是Python 2.6.6，yum中最新的也是Python 2.6.6，只能下载Python 2.7.12的源代码自己编译安装。

操作步骤如下：

1）安装Development tools

yum groupinstall "Development tools"

2）安装编译Python需要的包包

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

yum install tcl-devel

yum install tk-devel

3）

下载并解压Python 2.7.12的源代码

cd /opt
wget --no-check-certificate https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz
tar xf Python-2.7.12.tar.xz
cd Python-2.7.12

4）编译与安装Python 2.7.12

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

5）将python命令指向Python 2.7.12（可省略）

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

6）检查Python版本

# python --version
Python 2.7.12
