CentOS 7.2 原始碼安裝Python 3.6

1.環境
安裝CentOS 7.2最小系統（CentOS-7-x86_64-Minimal-1511.iso）

2.需求
Python-3.6.4.tar.xz（官網下載）

GCC（yum安裝）

一堆開發庫（yum安裝）

3.編譯
3.1安裝編譯器
yum -y install gcc3.2安裝依賴

yum -y install bzip2-devel sqlite-devel openssl-devel readline-devel xz-devel xz-devel tk-devel gdbm-devel3.3編譯原始碼
tar Jxvf Python-3.6.4.tar.xz

cd Python-3.6.4

./configure

（如果需要發布版，則設定時要開優化，編譯較慢./configure --enable-optimizations）
make -j4

make install預設安裝到/usr/local

注意如果不安裝3.2依賴開發庫，則編譯完成後會提示有些模組沒有編譯

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.執行
[root@py3 Python-3.6.4]# python3
