1.从官网下载Python源代码并解压缩到指定目录。
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz
xz -d Python-3.6.1.tar.xz
tar -xvf Python-3.6.1.tar
2.切换至Python源代码目录并执行下面的命令进行配置和安装。
cd Python-3.6.1
./configure --prefix=/usr/local/python3.6 --enable-optimizations
make && make install
3.如果安装失败，安装依赖库（因为没有这些依赖库可能在源代码构件安装时因为缺失底层依赖库而失败）
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
