    1、CentOS6.5 安装Python 的依赖包

    yum groupinstall "Development tools"
    yum install  gcc zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

    2、下载Python3.5的源码包并编译

    wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz
    tar xf Python-3.5.0.tgz
    cd Python-3.5.0
    ./configure --prefix=/usr/local/python
    make
    make install
    ln -s /usr/local/python/bin/python3 /usr/bin/python3

    3、在运行Python之前需要配置库：

    echo /usr/local/python/lib >> /etc/ld.so.conf.d/local.conf
    ldconfig

    4、运行演示：

    python3 --version
    Python 3.5.0

    5、删除编译Python时所需要的库

    yum groupremove "Development tools" --remove-leaveas
    yum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel --remove-leaves

    6、设置别名方便使用

    alias py=python3
