I am using `node_redis` to connect from a Nodejitsu app to OpenRedis,
both running on Joyent.
Frequently the Nodejitsu app loses connection. Excerpt from the logs:
[12/22 12:45:07 GMT+0100] Redis connection to
165.225.131.162:10657 failed - read ETIMEDOUT
[12/22 12:45:07 GMT+0100] Redis connection to
165.225.131.162:10657 failed - read ETIMEDOUT
[...]
[12/22 12:45:07 GMT+0100] Redis connection to
165.225.131.162:10657 failed - read ETIMEDOUT
[12/22 12:45:07 GMT+0100] Redis client: [Error: Redis connection
to 165.225.131.162:10657 failed - read ETIMEDOUT]
Now, I contacted OpenRedis, and they looked at the log of the Redis
instance and said that things look OK. In fact, the instance on
Joyent is underutilized.
Questions:
* How do I find out where the error lies?
* Does `node_redis` support some kind of automatic reconnect?
The code that the Nodejitsu app uses to connect to Redis:
var port = process.env.REDIS_PORT || 6379,
host = process.env.REDIS_HOST || '127.0.0.1',
password = process.env.REDIS_PASSWORD,
redisClient = require('redis').createClient(port, host);
if (password) {
redisClient.auth(password);
}
redisClient.on('error', function (err) {
console.error('Redis client:', err);
});
redisClient.setMaxListeners(0);
module.exports = redisClient;
