CentOS 7.2 源碼安裝Python 3.6

CentOS 7.2 源碼安裝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 gcc

3.2安裝依賴

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

3.3編譯源碼

tar Jxvf Python-3.6.4.tar.xzcd Python-3.6.4./configure

（如果需要發布版，則配置時要開最佳化，編譯較慢./configure --enable-optimizations） 

make -j4make 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
