 #### Q: frpc 启动失败怎么办？
 
-检查 frpc.toml 配置是否正确，或查看 ./frpc.log 日志文件。
+如果是首次启动，console 会自动生成一份符合官方规范的 `frps.toml` 配置文件，通常不需要额外操作。
+
+如果在使用过程中遇到启动失败，可以按以下步骤排查：
+
+1. **检查配置是否正确** —— 在「全局配置」页面重新配置一次服务端参数，或导入已有的 `frpc.toml` 配置文件，console 会自动应用并尝试重启
+2. **查看日志定位问题** —— 若上述操作后仍然失败，请查看 `./frpc.log` 日志文件，定位具体报错原因
+
+> 日志文件的位置：与 `frpc-console` 二进制同级目录下的 `frpc.log`。Docker 部署时，可通过 `docker logs frpc-console` 查看容器输出。
 
 #### Q: 支持哪些 frp 版本？
