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

# 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
