+# Linux 部署步骤（给 mohe 参考）
+
+## 1. hermes-gateway@.service
+
+```bash
+# 复制模板
+sudo cp /path/to/deploy/linux/hermes-gateway@.service /etc/systemd/system/
+sudo systemctl daemon-reload
+
+# 启用默认 gateway（8642端口）
+sudo systemctl enable --now hermes-gateway@default
+
+# 验证
+systemctl status hermes-gateway@default
+```
+
+## 2. state.db 清理
+
+```bash
+cd ~/.hermes/profiles/main
+
+# 方案A：CLI 清理（推荐）
+hermes session prune --older-than 30d
+
+# 方案B：手动清理
+sqlite3 state.db "DELETE FROM sessions WHERE time_created < strftime('%s','now','-30 days'); VACUUM;"
+```
+
+## 3. Provider key 迁移
+
+```yaml
+# config.yaml 中用环境变量替换
+providers:
+  volcengine:
+    api_key: ${VOLCENGINE_KEY}    # 从 .env 读取
+  ocg-new:
+    api_key: ${OCG_NEW_KEY}
+  ocg-old:
+    api_key: ${OCG_OLD_KEY}
+```
+
+```bash
+# .env 文件
+echo "VOLCENGINE_KEY=xxx" >> ~/.hermes/.env
+echo "OCG_NEW_KEY=xxx" >> ~/.hermes/.env
+echo "OCG_OLD_KEY=xxx" >> ~/.hermes/.env
+```
