利用playbook配置不同版本系统的yum源

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

项目结构

[root@ansible yum]# tree
.
├── ansible.cfg
├── inventory
└── yum.yml

0 directories, 3 files

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": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
centos7 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

编写配置yum的playbook

[root@ansible yum]# vim yum.yml
