playbook实现不同系统yum仓库配置

环境介绍

ip地址	系统和版本号	名称
192.168.102.134	ansible主控机	cst
192.168.102.140	CentOS7	c7
192.168.102.141	CentOS8	c8
192.168.102.142	RedHat7	r7
192.168.102.143	RedHat8	r8

配置主控机

//创建项目
[root@cst ~]# yum -y install ansible
[root@cst ~]# mkdir myrepo
[root@cst ~]# cd myrepo
[root@cst myrepo]# cp /etc/ansible/ansible.cfg .
[root@cst ~]# vim /etc/ansible/ansible.cfg 

inventory      = /etc/ansible/inventory

//为其主机写映射，方便操作
[root@cst ~]# vim /etc/hosts 

192.168.102.140 c7
192.168.102.141 c8
192.168.102.142 r7
192.168.102.143 r8

//配置清单文件
[root@cst myrepo]# vim inventory

c7
c8
r7
r8

//为其他主机做ssh连接
[root@cst myrepo]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
/root/.ssh/id_rsa already exists.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:FgrLx7dWSGIrz2KAlNH4VgVIHXjGncx3B1NXgqpbkEw root@cst
The key's randomart image is:
