									ansible 2.4.1.0

									 config file = None

									 configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

									 ansible python module location = /usr/lib/python2.7/site-packages/ansible

与宿主机(192.168.163.172)进行沟通，事先设定ssh通路，可以使用ssh-copy-id

									/ # ssh-copy-id 192.168.163.172

									/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"

									The authenticity of host '192.168.163.172 (192.168.163.172)' can't be established.

									ECDSA key fingerprint is SHA256:uh84Xw56LhiCXb1b0uFbX/CoFhkqHGZjtmLwl3qkTOY.

									Are you sure you want to continue connecting (yes/no)? yes

									/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

									expr: warning: '^ERROR: ': using '^' as the first character

									of a basic regular expression is not portable; it is ignored

									/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys

									root@192.168.163.172's password: 

									Number of key(s) added: 1

									Now try logging into the machine, with:  "ssh '192.168.163.172'"

									and check to make sure that only the key(s) you wanted were added.

ssh通路确认

									/ # ssh 192.168.163.172 hostname

									occluster

									/ #

ansible动作确认

									/ # echo "192.168.163.172" >>/etc/ansible/hosts

									/ # ansible 192.168.163.172 -m ping

									192.168.163.172 | SUCCESS => {
