Ansible可同时操作属于一个组的多台主机，组与主机之间关系配置在inventory文件中，inventory默认的配置文件是/etc/ansible/hosts

1、在/etc/ansible/hosts文件中配置两个组，分别为test1和test2

[test1]
192.168.144.129

[test2]
192.168.144.130

1.1、对一个组操作

[root@client01 ansible]# ansible test1 -m ping
192.168.144.129 | SUCCESS => {
"changed": false,
"failed": false,
"ping": "pong"
}

1.2、对两个组同时操作

[root@client01 ansible]# ansible test1:test2 -m ping
192.168.144.130 | SUCCESS => {
"changed": false,
"failed": false,
"ping": "pong"
}
192.168.144.129 | SUCCESS => {
"changed": false,
"failed": false,
"ping": "pong"
}

除了默认使用/etc/ansible/hosts，还可用通过-i选项指定inventory文件

[root@client01 ansible]# ansible all -i /home/zhuwan/ansible/hosts -m ping
192.168.144.129 | SUCCESS => {
"changed": false,
"failed": false,
"ping": "pong"
}
