需要Minion端安装Redis的python驱动
# -*- coding: utf-8 -*- ''' Return data to a redis server To enable this returner the minion will need the python client for redis installed and the following values configured in the minion or master config, these are the defaults: redis.db: '0' redis.host: 'salt' redis.port: 6379 To use the redis returner, append '--return redis' to the salt command. ex: salt '*' test.ping --return redis '''
