seata注册到nacos服务无法访问问题

今天遇到了个奇葩问题,在阿里云服务器上启动了seata并且注册到nacos上面,本地服务却死活访问不了,报错如下:

到网上找了一大堆,都是千篇一律说配置问题,但仔细检查配置并无差错。其实看到nacos上面seata服务的这个ip,我就觉得不太对劲(因工作原因,马赛克掉了ip地址),并不是阿里云的公网ip。

后来仔细查看了nacos注册ip的资料,才发现问题所在。就是nacos上的seata服务ip是服务器内网ip而非公网ip导致本地服务无法访问的。

在Windows下,启动seata时如果没有指定ip,就会导致服务注册使用内网ip,通过指定ip为公网ip
即可:

seata-server.bat -h 公网ip
