Redis could not be reconnected on Linux, but could work on Mac.

[KevinMcSun]

Version: 2.7.1
Code:

       redis.createClient(redisUrl, {
        connect_timeout: 60 * 1000,
        retry_strategy: function (options) {
          if (options.error && options.error.code === 'ECONNREFUSED') {
            return new Error('The server refused the connection');
          }
          if (options.total_retry_time > 1000 * 60) {
            return new Error('Retry time exhausted');
          }
          if (options.attempt > 10) {
            return undefined;
          }
          return 60000;
        }
      })

I just expect that the node redis could detect the disconnection in 1 mins and reconnect to redis server in given time successfully when the redis server is ready, but this code dose not work on my Linux env (Ubuntu 18.04), it could work on my Mac env, so could any experts give some help?

Is your options variable pulling through in your Linux env?

console.log(JSON.stringify(options, null, 4))

I can confirm, this is a BUG!

I run pm2, it restarts your app in the event of a Redis failure. But this needs to be fixed!

@KevinMcSun can you please elaborate in what way it works on Mac but not on Linux?

[KevinMcSun]

@BridgeAR, sure, here's my steps:

1. Start my redis service in physical machine 1.
2. Start my app in physical machine 2 and my app could connect the redis server successfully.
3. Then pull out the network cable of machine 1, Mac could detect the disconnection in 2 minutes, but Linux needs about 16 minutes.
4. Then plug in the network cable for machine 1(redis server), Mac could reconnect the redis server in about 2 minutes, but Linux.......I didn't see any re-connection in 30 minutes.

If any question, please feel free to contact me. Thanks again for your reply.
