利用playbook配置不同版本系统得到yum源
环境说明：
| 主机名和IP地址 | 系统版本 |
|---|---|
| ansible 192.168.153.10 | redhat 8.2 |
| redhat8 192.168.153.11 | redhat 8.2 |
| centos8 192.168.153.12 | centos 8 |
| centos7 192.168.153.13 | centos7 |

准备工作
本次环境yum源是阿里云官方镜像网站
//映射主机名IP
[root@ansible ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.153.10 ansible
192.168.153.11 redhat8
192.168.153.12 centos8
192.168.153.13 centos7
//编写inventory清单
[root@ansible ~]# mv /etc/ansible/inventory yum/ //把清单文件移到yum目录下
[root@ansible yum]# vim inventory
[redhat]
redhat8
[centos]
centos7
centos8
//修改清单的位置
[root@ansible ~]# mv /etc/ansible/ansible.cfg yum/ //把ansible.cfg移到yum目录下
[root@ansible yum]# vim ansible.cfg
# some basic default values...
inventory = ./inventory //当前目录的inventory
//设置免密登录
[root@ansible yum]# ssh-keygen -t rsa //生成密钥,直接回车
[root@ansible yum]# ssh-copy-id root@redhat8
[root@ansible yum]# ssh-copy-id root@centos8
[root@ansible yum]# ssh-copy-id root@centos7
//测试能否ping通
[root@ansible yum]# ansible all -m ping
redhat8 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
centos8 | SUCCESS => {
"ansible_facts": {

}
centos7 | SUCCESS => {

编写配置yum的playbook
[root@ansible yum]# vim yum.yml
