Centos7.6一鍵在線（離線）安裝python3.6.5和在線（離線）ansible2.9.9

如果只是安裝ansible，簡單點的在線安裝如下：

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

yum clean all

yum makecache

yum install ansible -y

因爲python3.6.5和ansible2.9.9在線安裝還是有點慢，下面這個腳本是如果有離線包且上傳了就離線安裝，未上傳就在線安裝（自動判斷）：

首先，掛載鏡像iso。並且確保能上網。上傳離線包Python-3.6.5.tar.xz（或者在線wget），上傳ansible離線包和所有依賴（或者在線pip）到根目錄下。新建以下腳本即可一鍵離線（在線）安裝python3.6.5和離線（在線）安裝ansible2.9.9。

ansible2.9.9基於Centos7.6離線包鏈接：https://download.csdn.net/download/fxqice/12552852

腳本新建：

vi ansible_setup.sh
