问题一:请问python注册nacos,加了账号密码还是报错提示权限不足注册不了怎么回事?
请问python注册nacos,加了账号密码还是报错提示权限不足注册不了怎么回事?client=nacos.NacosClient('127.0.0.1:8848',namespace='dev-id',username="nacos", password="nacos")我在java里面用nacos sdk 都可以正常使用。
参考回答:
在使用 Python SDK 注册 Nacos 时,如果配置了账号密码,需要确保账号密码的正确性,并且账号需要具有注册权限。如果账号密码正确,但仍然提示权限不足,可能是因为 Nacos Server 的权限配置存在问题。
你可以尝试以下方法解决问题:
- 确认你使用的 Nacos Server 版本是否支持账号密码认证,如果不支持,则无法使用账号密码注册。在 Nacos 1.4.0 及以上版本中,支持使用账号密码进行认证。
- 确认你在 Python SDK 中配置的账号密码是否正确,可以尝试使用其他工具(如浏览器)登录 Nacos 控制台,检查账号密码是否生效。
- 确认你在 Nacos Server 中配置的权限是否正确,可以尝试在 Nacos 控制台中查看该账号是否具有注册权限。如果没有注册权限,可以在 Nacos 控制台中添加该账号的注册权限。
- 如果以上方法都无法解决问题,可以尝试重新启动 Nacos Server,并检查 Nacos Server 的日志文件,查看是否存在相关错误信息。
总之,如果你无法通过 Python SDK 注册 Nacos,需要先确认账号密码的正确性,并检查 Nacos Server 的权限配置和日志信息,以找到问题所在。

问题二:Nacos客户端接收解析Udp包偶现报错日志,但是客户端和服务器Nacos正常运行,是啥原因?
Nacos客户端接收解析Udp包偶现报错日志,但是客户端和服务器Nacos正常运行,是啥原因?2023-05-05 12:32:05.417 ERROR[com.alibaba.nacos.naming.push.receiver]com.alibaba.nacos.client.naming.run:113 -[NA] error while receiving push data com.alibaba.nacos.api.exception.runtime.NacosDeserializationException: errCode: 101, errMsg: Nacos deserialize for class [com.alibaba.nacos.client.naming.core.PushReceiver$PushPacket] failed.Version [e.g. nacos-server 2.0.3, nacos-client 1.4.1]Caused by: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'OPTIONS': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false') at [Source: (String)"OPTIONS sip:100@XXX.224.212.117 SIP/2.0
参考回答:
这个错误日志显示 Nacos 客户端在接收推送数据时出现了反序列化异常,具体来说是在将推送数据反序列化为 com.alibaba.nacos.client.naming.core.PushReceiver$PushPacket
对象时失败了。错误信息中提到了 com.fasterxml.jackson.core.JsonParseException
异常,这个异常是由 Jackson 序列化/反序列化库抛出的,一般是由于传入的数据格式不符合 JSON 格式所致。
根据错误信息中提供的内容,异常信息的源头是 OPTIONS sip:100@XXX.224.212.117 SIP/2.0
,这是一个 HTTP 请求的方法和路径部分,但是不符合 JSON 格式,因此导致了反序列化异常。从这个错误信息来看,可能是某个应用程序误将 HTTP 请求发送到了 Nacos 服务器的推送端口(默认是 8848),导致了推送数据的格式异常,从而导致了 Nacos 客户端的反序列化异常。
如果这个错误只是偶现的,而且没有影响到 Nacos 的正常运行,那么可以先观察一下是否有某个应用程序在调用 Nacos 推送接口时发送了异常的请求。如果发现了问题的应用程序,可以修复它的代码,让它发送正确格式的请求。如果找不到问题所在,也可以考虑升级 Nacos 客户端的版本,或者将错误日志上报给 Nacos 官方,看看是否有更好的解决方案。

问题三:nacos服务端2.0.3 启动报错
1、问题描述:新手使用nacos,建立linux堡垒机,./startup.sh后日志报错。
2、环境:
① 堡垒机环境Centos7 ② jdk1.8.0_302
3、已尝试方法
①#4089
根据该方法修改jdk版本到jdk1.8.0_202,失败。
②https://blog.csdn.net/weixin_42982636/article/details/108221299
根据该方法尝试过window的nacos,可以启动,但是该方法单例模式,我想尝试集群模式启动。
4、启动异常

问题五:Nacos这个8850的端口为什么报错0.0.0.0:7848地址被占用啊?
Nacos这个8850的端口为什么报错0.0.0.0:7848地址被占用啊?
参考回答:
这种情况可能是因为8850端口已经被其他进程占用了,导致Nacos无法启动。您可以使用以下命令查看端口占用情况:
lsof -i :8850
如果该端口已经被占用,您可以使用以下命令杀死占用该端口的进程:
kill -9 <PID>
其中,是占用该端口的进程ID。然后您可以重新启动Nacos服务。
