READONLY You can't write against a read only replica.

[thaitanloi365]

Hi,
I'm using this library in many projects. Sometimes I was getting this error. I only used this library for caching purposes with basic Get,Set function.
Here is my redis configuration:

	var cache = redis.New(&redis.Config{
			Namespace:         config.RedisNamespace,
			DefaultExpiration: time.Hour * 2,
			Options: &goredis.Options{
				Addr:         config.RedisAddress,
				DB:           config.RedisDBMode,
				Password:     config.RedisPassword,
				PoolSize:     1000,
				PoolTimeout:  2 * time.Minute,
				IdleTimeout:  10 * time.Minute,
				ReadTimeout:  2 * time.Minute,
				WriteTimeout: 1 * time.Minute,
			},
		})

Please help me to troubleshoot this issue. Thanks.

this is not an error of redis.Client, please read the redis documentation: https://redis.io/topics/replication#read-only-replica

I think salves are by default readonly, so you can remove this error by changing their readonly status.
redis-cli -h 127.0.0.1 -p 6379 slaveof no one

According to the redis document,it's best that slave read only.I faced to this problem because there is no master role in my redis.After fix redis replication problem,then I can write in redis sentinel mode.

My problem was that the Redis port was exposed to the internet and I wasn't aware.

This is not a problem related to go-redis, as stated previously - please review your redis setup if you are experiencing this.
