    python3.6环境搭建

    安装依赖

    yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel gcc libffi-devel python-devel openssl-devel libcurl-dev libcurl-devel

    获取tgz包(以3.6.4为例)

    wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

    解压并切换目录

    tar -zxvf Python-3.6.4.tgz
    cd Python-3.6.4

    执行安装

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

    创建Python3的软链接

    ln -s /usr/local/bin/python3 /usr/bin/python3

    创建Pip3的软链接

    ln -s /usr/local/bin/pip3 /usr/bin/pip3

    由于CentOS7默认安装python2.7.5,有些同学想要更新成最新版本(此处以目前最新版本2.7.14为例)

    python2.7.14环境搭建

    获取tgz包(以2.7.14为例)

    wget https://www.python.org/ftp/python/2.7.14//Python-2.7.14.tgz

    解压并切换目录

    tar -zxvf Python-2.7.14.tgz
    cd Python-2.7.14

    执行安装

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

    将老版本python更换,并更换PATH路径

    mv /usr/bin/python /usr/bin/python2.7.5
    export PATH="/usr/local/bin:$PATH"

    创建python2.7.14软连接

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

    创建Pip2的软链接

    ln -s /usr/local/bin/pip2 /usr/bin/pip2

    更改yum的python依赖

     注:作者把默认python的软连接改为2.7.5了,以下以2.7.5示例

    cd /usr/bin
    ls yum*

    yum yum-builddep yum-config-manager yum-debug-dump yum-debug-restore yumdownloader yum-groups-manager

    更改以上文件头为

    #!/usr/bin/python 改为 #!/usr/bin/python2.7.5

    此时便大功告成了!
