问题：
[DEPRECATION WARNING]: [defaults]hostfile option, The key is misleading as it can also be a list of hosts, a directory or a list of paths , use [defaults]
inventory=/path/to/file|dir instead. This feature will be removed in version 2.8. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
解决：
sudo vim /etc/ansible/ansible.cfg
hostfile = hosts 改成 inventory = hosts
问题：
to use the 'ssh' connection type with passwords, you must install the sshpass program
解决：
brew search sshpass
We won't add sshpass because it makes it too easy for novice SSH users to ruin SSH's security.
brew create https://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz --force
brew install sshpass
问题：
[WARNING]: Found both group and host with same name: server209
