1.问题描述：
可能是国内的网络原因，在线用pyenv安装python老是定住没反应
[root@zabbix ~]# pyenv install 3.6.
Downloading Python-3.6..tar.xz...
-> https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
2.安装配置
安装前需要在pyenv目录下创建cache文件夹，没有的情况
[root@zabbix ~]# cd ~/.pyenv/
[root@zabbix .pyenv]# mkdir cache
下载离线包利用wget，需要进入cache目录下
[root@zabbix cache]# wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

然后查看目录下有没有python的tar包
[root@zabbix cache]# ls
Python-3.6..tar.xz
查看到已经下载成功以后再用pyenv安装python
[root@zabbix ~]# pyenv install 3.6.

Installed Python-3.6. to /root/.pyenv/versions/3.6.
最后查看是否安装成功
[root@zabbix ~]# pyenv versions

3.6.
