需要准备控制机和被控机，在控制机上安装ansible，被控机能ping通
1.安装ansible
2.mkdir -p /root/ansible/roles
3.vim /root/ansible/inventory
inventory内容：
[root] #主机名称
172.30.201.207 #被控机名称
[all:vars] #所有参数
ansible_user=root #被控机用户名
ansible_password=Qwer!234 #被控机密码
4.cp -vp /etc/ansible/ansible.cfg /root/ansible/ansible.cfg
5.vim /root/ansible/ansible.cfg
#总共只修改四行
inventory = /root/ansible/inventory
roles_path = /root/ansible/roles
host_key_checking = False
remote_user = root
6.ansible --version
7.ansible-inventory --graph
结果
1.cd /root/ansible
2.ansible all -m hostname -a name=dyb
预期结果
[root@ans-01 ansible]# ansible all -m hostname -a name=dyb
