CentOS 6.9编译安装Python-2.7.10
Python官网：https://www.python.org/一、查看CentOS版本和系统默认Python版本：
# cat /etc/redhat-release
# python -V
二、编译安装Python-2.7.10：
1、安装依赖软件包及包组：
# yum -y groupinstall "Development tools"
# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-develsqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-develxz-devel man
2、设置CentOS 6.9当前系统时间：
# date 071017452017.20
# date
3、编译安装Python-2.7.10：
# tar -xf Python-2.7.10.tar.xz -C /usr/src
# cd /usr/src/Python-2.7.10
# ./configure --prefix=/usr/local/python2.7.10 --enable-shared--enable-profiling --disable-ipv6 --with-signal-module --with-dec-threads--with-threads --with-pth --with-doc-strings --with-tsc --with-pymalloc--with-wctype-functions --with-fpectl | tee /tmp/python2.7.10.out
# less /tmp/python2.7.10.out
# make && make install
4、更改CentOS 6.9的默认Python版本为2.7.10：
# mv /usr/bin/python /usr/bin/python2.6.6-old
# ln -s /usr/local/python2.7.10/bin/python2.7 /usr/bin/python
5、添加至PATH环境变量：
# vim /etc/profile.d/python2.7.10.sh
export PATH=/usr/local/python2.7.10/bin:$PATH
# . /etc/profile.d/python2.7.10.sh
# echo $PATH
6、配置头文件：
# ln -s /usr/local/python2.7.10/include /usr/include/python2.7.10
7、配置库文件：
# echo "/usr/local/python2.7.10/lib" >/etc/ld.so.conf.d/python2.7.10.conf
# cat /etc/ld.so.conf.d/python2.7.10.conf
# ldconfig
8、配置man帮助文档：
# vim /etc/man.config，新增如下代码：
MANPATH /usr/local/python2.7.10/share/man
9、查看配置后的Python版本：
# python -V
# python2 -V
三、将yum中的Python版本修改为系统原来的2.6.6版本：
升级Python后会导致yum无法使用：
# vim /usr/bin/yum，将第一行的“#!/usr/bin/python”修改为“#!/usr/bin/python2.6.6-old”
四、Python版本从2.6.6升级到2.7.10，导致pip无法使用，修复pip：
# pip -V
# yum -y install python-pip wget
# wget -q https://bootstrap.pypa.io/get-pip.py
# python get-pip.py
# mv /usr/bin/pip /usr/bin/pip2.6.6-old
# ln -s /usr/local/python2.7.10/bin/pip2.7 /usr/bin/pip
