redis-py-cluster一坑记录

按照文档例子来一发，发现错误呀，单用redis-py错误呀

>>> from rediscluster import StrictRedisCluster

>>> # Requires at least one node for cluster discovery. Multiple nodes is recommended.
>>> startup_nodes = [{"host": "127.0.0.1", "port": "7000"}]

>>> # Note: decode_responses must be set to True when used with python3
>>> rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)

>>> rc.set("foo", "bar")
True
>>> print(rc.get("foo"))
'bar'

cluster错误如下：

ResponseError: unknown command 'CONFIG'

想死有没有，各种找不到答案

看到这篇文章，原来server可以选择屏蔽一些命令的，然后，搜索redis-py-cluster源码，找到这么一句

If your redis instance is configured to not have the `CONFIG ...` comannds enabled due to security reasons you need to pass this into the client object `skip_full_coverage_check=True`. Benefits is that the client class no longer requires the `CONFIG ...` commands to be enabled on the server. Downsides is that you can't use the option in your redis server and still use the same feature in this client.

加了一个skip_full_coverage_check=True搞定
