frp在ubuntu下无法使用，如何排错寻找问题？

Question

问题描述

尝试在ubuntu下搭建frp服务器，软件启动没有报错，连接的时候出错连不上。

环境参数

• 系统平台：aliyun ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-117-generic x86_64)
• frp版本：frp_0.20.0_linux_amd64
• 安全组策略：开放所有端口
• oneinstack部署了nginx，并利用其脚本生成了一个https协议的vhost，用于跑主web服务

dashboard_port = 7500
dashboard_user = frp_admin
dashboard_pwd = frp_2018100800

做过的检查

通过netstat命令查看，没有看到7000端口

做过的改进工作

听从群友给出换端口的建议，改为8000后，确实可以看到了端口了，但依旧连不上

Answer 1

系统原因，重装阿里云系统后重新安装就好了

Answer 2

删除frps.ini 里的bind_addr = 127.0.0.1这个配置
