pyenv离线安装python各版本

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 3.6.2
Downloading Python-3.6.2.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-3.6.2.tar.xz

查看到已经下载成功以后再用pyenv安装python

[root@zabbix ~]# pyenv install 3.6.2
Installing Python-3.6.2...
Installed Python-3.6.2 to /root/.pyenv/versions/3.6.2

最后查看是否安装成功

[root@zabbix ~]# pyenv versions
* system (set by /root/.pyenv/version)
  3.6.2
