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:
+---[RSA 3072]----+
| .+.=oB.. ooo..o|
| .o+ * =E. .o... |
| o. = oo+.... |
|.. + = =+o. |
