编译安装Python3

安装依赖

yum install -y ncurses-libs zlib-devel mysql-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

发现的问题：如果不安装readline-，python解释器无法使用上下左右箭头； 不安装openssl-， pip无法使用，不安装zlib-devel，编译无法通过。其他问题待发现后再补充。

下载安装包

wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tar.xz

这里以root身份运行以下命令：

tar xf Python-3.6.7.tar.xz
cd Python-3.6.7
./configure && echo ok
make && make install && echo ok

安装后验证
