取出两组中的交集

[root@CentOS6 auto]# ansible Login:\&Player -m ping  交集

No hosts matched


表示两个组中的所有主机

[root@CentOS6 auto]# ansible Login:Player -m ping 

player_centos6.5-2 | success >> {

    "changed": false, 

    "ping": "pong"

}


login_centos6.5-1 | success >> {

    "changed": false, 

    "ping": "pong"

}


非的表达式，目标主机在Login组中但不在Player组中

[root@CentOS6 auto]# ansible all:\!Player -m ping

login_centos6.5-1 | success >> {

    "changed": false, 

    "ping": "pong"

}


room_centos6.5-3 | success >> {

    "changed": false, 

    "ping": "pong"

}


session_centos6.5-4 | success >> {

    "changed": false, 

    "ping": "pong"

}


[root@CentOS6 auto]# 


eg:

----------

[Login]

login_centos6.5-1 ansible_ssh_host=192.168.31.129

player_centos6.5-2 ansible_ssh_host=192.168.31.202
