+
+**问题描述**：微服务启动时报错：
+```
+io.lettuce.core.RedisReadOnlyException: READONLY You can't write against a read only replica.
+```
+
+**原因**：微服务使用单机模式连接 Redis（`REDIS_HOST`/`REDIS_PORT`），直接连接到了 Redis 从节点，而从节点是只读的。
+
+**解决方案**：
+
+1. 确保所有微服务使用 **Redis Sentinel 模式** 连接。在 `docker-compose-node-xx.yml` 中配置环境变量：
+
+```yaml
+environment:
+  # 删除 REDIS_HOST 和 REDIS_PORT，改用 Sentinel
+  - REDIS_PASSWORD=${REDIS_PASSWORD:-redis_HA_Cluster_2024}
+  - REDIS_SENTINEL_NODES=${REDIS_SENTINEL_NODES:-192.168.1.101:26379,192.168.1.102:26379,192.168.1.103:26379}
+```
+
+2. 确保 `application-ha.yml` 配置正确：
+
+```yaml
+spring:
+  data:
+    redis:
+      password: ${REDIS_PASSWORD:redis_HA_Cluster_2024}
+      database: 0
