1.设置主机名
命名命令:hostnamectl set-hostname xx
设置4台主机
servera serverb serverc serverd
2.配置扩展源
1)cd /etc/yum.reops.d/
2)vim local.repo
[biaoshi]
name=miaoshu
baseurl=/mnt/BaseOS
enable=1
gpgcheck=0
[biaoshi2]
name=miaoshu2
baseurl=/mnt/AppStream
enable=1
gpgcheck=0
mount /dev/sr0 /mnt
3.域名映射
在servera上设置
vim /etc/hosts
192.168.233.132 servera
192.168.233.139 serverb
192.168.233.140 serverc
192.168.233.141 serverd
4.servera以root配置到所有机器免密互信
[root@servera ~]# ssh-keygen -f ~/.ssh/id_rsa -P ' ' -q
[root@servera ~]# ls ~/.ssh
id_rsa id_rsa.pub
分发到所有节点:
[root@servera ~]# for i in server{a..d}
> do
> ssh-copy-id $i
> done
验证:
[root@servera ~]# for i in server{a..d}; do ssh $i hostname; done
servera
serverb
serverc
serverd
5.servera安装ansible
[root@servera ~]# yum install ansible -y
6.创建配置文件和清单文件
[root@servera ~]# mkdir ansible
[root@servera ~]# cd ansible
[root@servera ansible]# cp /etc/ansible/ansible.cfg .
[root@servera ansible]# vim inventory
[dev]
servera
[test]
serverb
[balancers]
serverb
[prod]
serverc
serverd
[webservers:children]
prod
[root@servera ansible]# ansible all -m ping
