Centos7搭建ansible运维自动化工具

1）设置主机名和hosts文件

2）配置阿里云repo源

Wget -O /etc/yum.repos.d/aliyun.repo https://mirrors.aliyun.com/repo/Centos-7.repo

3）创建ssh免交互登录

[root@ansible ~]# ssh-keygen -t rsa -P "" -f .ssh/id_rsa

[root@ansible ~]# sshpass -p 666666 ssh root@192.168.30.24 -o StrictHostKeyChecking=no

[root@ansible ~]# sshpass -p 666666 ssh-copy-id root@192.168.30.24 -o StrictHostKeyChecking=no

测试

[root@ansible ~]# ssh root@192.168.30.25

Last login: Wed May 15 17:07:10 2019 from ansible

[root@client1 ~]# hostname

client1

[root@client1 ~]# exit

登出

4）在/etc/ansible/hosts文件中添加管理主机组，以后可根据组成员进行批量管理

vim /etc/ansible/hosts

[cloud]

192.168.30.25

192.168.30.26

[root@ansible ~]# ansible cloud -m ping

client1 | SUCCESS => {

"changed": false,

"ping": "pong"

}

[root@ansible ~]# ansible cloud -a "free -m"

client1 | SUCCESS | rc=0 >>
