    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-3.6.1

    1、安装依赖软件包:

    # yum -y groupinstall "Development tools"

    # yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel man

    2、设置CentOS6当前系统时间:

    # date 040413022017.30

    # date

    3、配置主机名解析:# vim /etc/hosts  -->  127.0.0.1 localhost

    4、编译安装Python-3.6.1

    # tar xf Python-3.6.1.tar.xz -C /usr/src

    # cd /usr/src/Python-3.6.1

    # ./configure --prefix=/usr/local/python3.6.1 --enable-shared --enable-profiling--enable-optimizations --disable-ipv6 --with-threads --with-pymalloc --with-fpectl--enable-loadable-sqlite-extensions

    # make && make install         //此步骤需要执行测试,用时较长

    4、更改CentOS 6.9默认Python版本为3.6.1

    # mv /usr/bin/python /usr/bin/python2.6.6-old

    # ln -s /usr/local/python3.6.1/bin/python3 /usr/bin/python

    # ln -s /usr/local/python3.6.1/bin/pip3 /usr/bin/pip

    5、添加至PATH环境变量:

    # vim /etc/profile.d/python3.6.1.sh

    exportPATH=/usr/local/python3.6.1/bin:$PATH

    # . /etc/profile.d/python3.6.1.sh

    # echo $PATH

    6、配置头文件:

    # ln -sv /usr/local/python3.6.1/include /usr/include/python3.6.1

    7、配置库文件:

    # echo "/usr/local/python3.6.1/lib" >/etc/ld.so.conf.d/python3.6.1.conf

    # cat /etc/ld.so.conf.d/python3.6.1.conf

    # ldconfig

    8、配置man帮助文档:

    # vim /etc/man.config,新增如下代码:

    MANPATH /usr/local/python3.6.1/share/man

    9、查看配置后的Python版本:

    # python -V

    # python3 -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
