 安装完成后浏览器打开 `https://api.synaglobal.vip/app/install.html` 完成向导。
 
+## Redis（自行安装，脚本不附带）
+
+Docker 栈仅含 **MySQL + Nexus**。Redis 请在宿主机或 1Panel 应用商店单独安装，监听 `127.0.0.1:6379`（或改 `docker/.env.prod` 的 `NEXUS_REDIS_URL`）。
+
+安装向导步骤 3：Docker 部署时 Redis 主机填 **`host.docker.internal`**，端口 `6379`。
+
 ## 1Panel 反代（必须在面板 UI 操作）
 
 **禁止** Agent/脚本直接 `mkdir` 或 `tee` 到 `/opt/1panel/apps/openresty/` — 会破坏 bind mount。

+# 2026-06-05 — Docker 栈移除内置 Redis
+
+## 摘要
+
+按用户要求，一键安装脚本 / `docker-compose.prod.yml` **不再附带 Redis 容器**。
+Redis 由用户在宿主机或 1Panel 应用商店自行安装；Nexus 默认连 `host.docker.internal:6379`。
+
+## 变更
+
+- `docker/docker-compose.prod.yml` — 删除 `redis` 服务与 `redis-data` 卷
+- `docker/entrypoint.sh` — 安装向导阶段不等待 Redis；否则有限次等待外置 Redis
+- `server/api/install.py` — Redis 环境检测改为**不阻塞**（`pass: true`）
+- `deploy/README-1panel.md` — 补充 Redis 自建说明
+- `docker/.env.prod.example` — 增加 `NEXUS_REDIS_URL`
+
+## 迁移（已装旧栈）
+
+```bash
+cd /opt/nexus && git pull
+docker stop nexus-prod-redis-1 2>/dev/null; docker rm nexus-prod-redis-1 2>/dev/null
+# 在宿主机/1Panel 安装 Redis 并监听 6379
+docker compose -f docker/docker-compose.prod.yml \
+  --env-file docker/.env.prod \
+  --env-file docker/profiles/$(cat docker/.host-profile).env \
+  up -d --build
+```
+
+## 安装向导
+
+- Docker：Redis 主机 `host.docker.internal`，端口 `6379`
+- 步骤 2 Redis 未连接也可继续
