今天我们来看看如果通过二进制方式安装Ansible。为了节约时间，部分组件的安装采用了在线的方式，如python3、pip。
---在线安装python3
# yum install -y python3
---使用python3来在线下载和安装pip最新版
---https://bootstrap.pypa.io/get-pip.py
# python3 get-pip.py

备注：
1）上面的whl文件，使用pip install *.whl命令安装即可。
2）tar.gz文件，需要解压后，使用python setup.py install命令安装，安装过程中还会在线下载一些依赖包。
在CentOS7.9系统中实测安装Ansible 4.8，最后发现CentOS7.9已经不能兼容Ansible 4.8了，建议在CentOS 8.x版本上安装。
