Issue of losing cache when restarting the Redis service?
If the Redis service loses its cache after restarting, you can try the following methods to resolve it:
- Check for backups: If you have previously set up Redis backup mechanisms, you can try to restore the backup data.
- Check the Redis configuration file to make sure the persistence options, such as RDB snapshots and AOF logs, are set correctly.
- Recovering using AOF log: If AOF log is enabled, data can be restored by replaying the AOF log.
- Enable persistence mechanism: You can activate the persistence mechanism in the Redis configuration file to ensure that data is not lost when the service is restarted.
- Consider using Redis Sentinel or Redis Cluster: Both options provide high availability and data backup capabilities, helping to prevent data loss.
If none of the above methods can solve the problem, you may consider reaching out to Redis official technical support or seeking help in the community.
