Python - How to check if Redis server is available
python, redis
Solution
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:
- check for a connection at instantiation
- write an exception handler in the case of no connectivity when making requests
Problem
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??
