Redis module path

/ usr/lib/python2.6/site-packages/salt/modules/redismod.py

The Redis module will first check if Redis's Python driver is installed.

#-*-coding: utf-8-* -''Module to provide redis functionality to Salt.. Versionadded:: 2014.7.0:configuration: This module requires the redis python module and uses the following defaults which may be overridden in the minion configuration:.. Code-block:: yaml redis.host: 'localhost' redis.port: 6379 redis.db: 0 redis.password: None'''# Import third party libstry: import redis HAS_REDIS = Trueexcept ImportError: HAS_REDIS = False__virtualname__ =' redis'def _ _ virtual__ ():''Only load this module if redis python module is installed''if HAS_REDIS: return _ virtualname__ else: return False

The Redis module name redis of SaltStack is returned only when the Python driver of Redis is installed.

Def _ connect (host=None, port=None, db=None Password=None):''Returns an instance of the redis client' if not host: host = _ salt__ ['config.option'] (' redis.host') if not port: port = _ salt__ ['config.option'] (' redis.port') if not db: db = _ salt__ ['config.option'] (' redis.db') if not password : password = _ salt__ ['config.option'] (' redis.password') return redis.StrictRedis (host Port, db, password)

If the IP, port and DB name and password of the Redis instance are not specified, the configuration file is read. Here you use the Python driver of redis to connect to Redis
