I'm developing a Python Service(Class) for accessing Redis Server. I want to know how to check if Redis Server is running or not. And also if somehow I'm not able to connect to it.
Here is a part of my code
import redis
rs = redis.Redis("localhost")
print rs
It prints the following
<redis.client.Redis object at 0x120ba50>
even if my Redis Server is not running.
As I found that my Python Code connects to the Server only when I do a set() or get() with my redis instance.
So I dont want other services using my class to get an Exception saying
redis.exceptions.ConnectionError: Error 111 connecting localhost:6379. Connection refused.
I want to return proper message/Error code. How can I do that??
The official way to check if redis server availability is ping ( http://redis.io/topics/quickstart ).
One solution is to subclass redis and do 2 things:
