+# WhaleTown V2 后端部署
+
+## 1. 生产配置
+
+```bash
+cp .env.production.example .env
+openssl rand -hex 32 # 分别用于 JWT_SECRET、ADMIN_TOKEN_SECRET 和 ZULIP_API_KEY_ENCRYPTION_KEY
+```
+
+必须填写 MySQL、Redis 和三个随机密钥。REST API 使用 `3000` 端口，原生 WebSocket 使用 `3001` 端口。不要把两个端口配成相同值。
+
+## 2. 数据库
+
+部署前先备份现有数据库。v2 不会自动修改表结构（`synchronize: false`）。根据目标库的现有结构审核并执行仓库内的增量 SQL：
+
+```bash
+mysql -u <user> -p <database> < src/core/db/player_assets/create-player-assets-tables.sql
+mysql -u <user> -p <database> < src/core/db/user_wallets/create-user-wallets-tables.sql
+mysql -u <user> -p <database> < src/business/notice/migrations/create-notices-table.sql
+```
+
+## 3. 构建与启动
+
+```bash
+pnpm install --frozen-lockfile
+pnpm run build
+VITE_API_BASE_URL=https://whaletownend.xinghangee.icu pnpm --filter whale-town-admin run build
+pm2 start ecosystem.config.js
+pm2 save
+```
+
+## 4. 反向代理
+
+`deploy/nginx/whaletownend-v2.conf.example` 将 REST 转发到 `3000`，将 `/game` WebSocket 转发到 `3001`。管理端可使用 `deploy/nginx/whaletown-admin-v2.conf.example` 作为独立静态站点。
+
+启用 HTTPS 后验证：
+
+```bash
+curl https://whaletownend.xinghangee.icu/
+curl https://whaletownend.xinghangee.icu/api-docs
+curl --http1.1 -i \
+  -H 'Connection: Upgrade' \
+  -H 'Upgrade: websocket' \
+  -H 'Sec-WebSocket-Version: 13' \
+  -H 'Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==' \
+  https://whaletownend.xinghangee.icu/game
+```

 启动前至少需要在 `.env` 中设置随机的 `JWT_SECRET`、`ADMIN_TOKEN_SECRET` 和 `ZULIP_API_KEY_ENCRYPTION_KEY`。生产环境请从 `.env.production.example` 开始配置，不要直接使用示例值。
 
-API 默认监听 `3000` 端口，Swagger 地址为 `/api-docs`。
+REST API 默认监听 `3000` 端口，原生 WebSocket 默认监听 `3001` 端口并使用 `/game` 路径，Swagger 地址为 `/api-docs`。生产环境的反向代理需要分别转发这两个端口。
