Centos7.6一键在线（离线）安装python3.6.5和在线（离线）ansible2.9.9

如果只是安装ansible，简单点的在线安装如下：

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum clean all

yum makecache

yum install ansible -y

因为python3.6.5和ansible2.9.9在线安装还是有点慢，下面这个脚本是如果有离线包且上传了就离线安装，未上传就在线安装（自动判断）：

首先，挂载镜像iso。并且确保能上网。上传离线包Python-3.6.5.tar.xz（或者在线wget），上传ansible离线包和所有依赖（或者在线pip）到根目录下。新建以下脚本即可一键离线（在线）安装python3.6.5和离线（在线）安装ansible2.9.9。

ansible2.9.9基于Centos7.6离线包链接：https://download.youkuaiyun.com/download/fxqice/12552852

脚本新建：

vi ansible_setup.sh
