CentOS 7.2 源码安装Python3.6

1.环境

安装CentOS 7.2最小系统（CentOS-7-x86_64-Minimal-1511.iso）

2.需求

Python-3.6.4.tar.xz（官网下载）

GCC（yum安装）

一堆开发库（yum安装）

3.编译

3.1安装编译器

yum -y install gcc

3.2安装依赖

yum -y install bzip2-devel sqlite-devel openssl-devel readline-devel xz-devel xz-devel tk-devel gdbm-devel

3.3编译源码

tar Jxvf Python-3.6..tar.xz

cd Python-3.6.

./configure

（如果需要发布版，则配置时要开优化，编译较慢./configure --enable-optimizations）

make -j4

// 注意： 源码编译安装后不好卸载，没有make uninstall这种命令，暂时没找到好的方案，有知道的可以留言哈。 -- 2018年6月22日 nidey
make install

默认安装到/usr/local

注意如果不安装3.2依赖开发库，则编译完成后会提示有些模块没有编译

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses               _curses_panel
_dbm                  _gdbm                 _lzma
_sqlite3              _ssl                  _tkinter
readline              zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
atexit                pwd                   time
running build_scripts

4.运行
