linu下python3安装

部署步骤参考：https://www.cnblogs.com/kimyeee/p/7250560.html
问题
1、wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz执行不通，域名无法解析：
vim /etc/hosts
在最后添加151.101.72.223 www.python.org
执行：wget https://151.101.72.223/ftp/python/3.6.1/Python-3.6.1.tgz
2、make遇错误：
错误问题：make: *** [pybuilddir.txt] 错误 1
解决方法：
在 ./configure 操作前，先进行配置
export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN.UTF-8
3、
pip3 install 第三方库遇到错误：
错误问题：
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f74f8bb9050>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution',)': /simple/pip/

Could not find a version that satisfies the requirement ** (from versions: ) 
No matching distribution found for simpejson
解决方法：
以上问题发现原来是DNS配置错误，域名服务器地址是本机IP地址，127.0.0.1，所以修改域名服务器
vim /etc/resolv.conf 
在文件最后添加：
nameserver  8.8.8.8
4、再次 pip3 install 第三方库遇到问题：
错误问题：
Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/local/python3/lib/python3.6/site-packages
You are using pip version 8.0.2, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
解决方法：
pip3 install --upgrade pip
5、import lightgbm遇到问题：
错误问题：
OSError: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/local/python3/lib/python3.6/site-packages/lightgbm/lib_lightgbm.so)
解决方法：
