关于nacos:解决Nacos-单机模式下报错server-is-DOWN-nowplease-try-again-later

原文地址：Nacos 单机模式下报错:server is DOWN now,please try again later!

Spring Boot 利用启动时连贯 Nacos 失败，报如下谬误：

com.alibaba.nacos.api.exception.NacosException: failed to req API:/nacos/v1/ns/instance after all servers([127.0.0.1:8848]) tried: ErrCode:503, ErrMsg:server is DOWN now, please try again later!
    at com.alibaba.nacos.client.naming.net.NamingProxy.reqApi(NamingProxy.java:552) ~[nacos-client-1.3.3.jar:na]
    at com.alibaba.nacos.client.naming.net.NamingProxy.reqApi(NamingProxy.java:491) ~[nacos-client-1.3.3.jar:na]
    at com.alibaba.nacos.client.naming.net.NamingProxy.reqApi(NamingProxy.java:486) ~[nacos-client-1.3.3.jar:na]

删除 nacos 目录下 data/protocol 目录，重新启动 nacos 服务。

cd nacos/data
# 删除 protocol 目录
rm -rf protocol/
# 重启
sh startup.sh -m standalone
