## -e 传变量
ansible webservers -m debug -a "var=role" -e "role=web"
[root@ceph1 ~]# ansible webservers -m debug -a "var=role" -e "role=web"
ceph3 | SUCCESS => {
    "role": "web"
}

ansible webservers -m debug -a "msg='role is {{role}}'" -e "role=web"
[root@ceph1 ~]# ansible webservers -m debug -a "msg='role is {{role}}'" -e "role=web"
ceph3 | SUCCESS => {
