启动后访问网址，打开是个白页面

realsmy

配置了自启动，重启服务器后，查看状态如下，貌似是启动成功了。

可是访问公网IP加端口号，却是白页面。求大佬指导。

realsmy 你好，日志不完整哦。

这个IP是内网IP。公网IP是http://101.200.150.157。
我尝试http://101.200.150.157:8090/admin，还是打不开。

johnniang

realsmy 嗯，确实已经启动成功了，确认是否有防火墙的阻挡。

wly000

请问楼主解决了么？我也遇到这个问题了

wly000

在阿里云服务器的实例安全组在入口和出口都添加8090端口就可以了

johnniang

wly000 以后只需要反向代理即可。
