+# Redis 部署说明
+
+## 配置信息
+
+- **命名空间**: redis
+- **存储**: 使用 Longhorn 提供 5Gi 持久化存储
+- **镜像**: redis:7-alpine
+- **持久化**: 启用 RDB + AOF 双重持久化
+- **内存限制**: 2GB
+- **访问地址**: redis.redis.svc.cluster.local:6379
+
+## 部署方式
+
+```bash
+bash deploy.sh
+```
+
+## 持久化配置
+
+### RDB 快照
+- 900秒内至少1个key变化
+- 300秒内至少10个key变化
+- 60秒内至少10000个key变化
+
+### AOF 日志
+- 每秒同步一次
+- 自动重写阈值: 64MB
+
+## 内存策略
+
+- 最大内存: 2GB
+- 淘汰策略: allkeys-lru (所有key的LRU算法)
+
+## 连接测试
+
+在集群内部测试连接：
+
+```bash
+kubectl run redis-test --rm -it --image=redis:7-alpine -- redis-cli -h redis.redis.svc.cluster.local ping
+```
+
+## 备份说明
+
+Redis 数据存储在 Longhorn 卷上，可以通过 Longhorn UI 创建快照和备份到 S3。
+
+## 监控
+
+可以通过以下命令查看 Redis 状态：
+
+```bash
+kubectl exec -n redis $(kubectl get pod -n redis -l app=redis -o jsonpath='{.items[0].metadata.name}') -- redis-cli info
+```
