保护 Redis 的安全至关重要,因为默认情况下,暴露的 Redis 实例可能会成为严重的漏洞 — 开放的 Redis 服务器已经造成了许多真实的数据泄露事件。安全性涉及身份认证、网络限制、TLS、命令限制和谨慎的配置。
网络安全(最重要)
⚠️ NEVER expose Redis directly to the internet. By default Redis trusts anyone who
can connect → an exposed instance lets attackers read/delete data, or worse.
✓ BIND to localhost/private interfaces only (bind 127.0.0.1 / private IPs)
✓ Firewall / security groups → only allow trusted app servers to reach port 6379
✓ Run Redis in a private network/VPC, never publicly accessible
→ Most Redis breaches stem from instances left open to the internet. This is #1.
