集群模式bug,使用discovery会报错java.lang.IllegalStateException: failed to req API:/nacos/v1/ns/instance after all servers([172.XX.XX.23:80]) tried 这个问题百度里也是大量反馈了 现在我用的全是最新的,还是有这个bug

[nkorange]

没有具体错误信息？客户端版本是什么？

[besthanliu]

0.9.0.RELEASE Server是1.1.3.另外0.9.0是最新客户端了吧,还是大量甩出心跳日志,很烦,并不是你说的最新版本默认关闭的. 以下贴出集群模式报错代码,顺便贴出百度上一个这个例子的"解决"方案:https://www.cnblogs.com/forezp/p/10136433.html

报错:

spring-cloud-alibaba最新版本依赖(nacos-client 1.1.1)，不是nacos-client最新版本(nacos-client 1.1.4)，你可以手动覆盖到nacos-client 1.1.4，如何覆盖请参考：https://nacos.io/zh-cn/docs/faq.html#3.15

另外我怀疑你依赖的不是0.9.0-RELEASE，nacos-client 1.1.1在NamingProxy 340行只是一个简单的map.put操作，不会出现空指针。你检查下以下依赖的版本是什么：

        <dependency>
            <groupId>com.alibaba.nacos</groupId>
            <artifactId>nacos-client</artifactId>
        </dependency>

[besthanliu]

我知道了,我没有添加到最新的客户端版本,我 稍后尝试,集群模式这个问题怎么办.特别影响

请更新到最新版本客户端，再重试看看是否还有问题。

[besthanliu]

有,现在ncos的spring-cloud-alibaba-dependencies和spring-cloud-starter-alibaba-nacos-*版本0.9.0-RELEASE，nacos-client 1.1.4,依然是这个问题,你们可以自己尝试下.server是部署在云服务器的,不是本地,然后采用集群模式,config没问题,discovery会报这个错误

麻烦贴一下最新的报错，主要看错误堆栈

基本上报错都是这些了:

如上图,整个盘都搜索过了,没有的,/usr/local/nacos,放的是nacos-server

如上图,整个盘都搜索过了,没有的,/usr/local/nacos,放的是nacos-server

你客户端和nacos-server跑在一个机器上？

[besthanliu]

嗯

[nkorange]

嗯

那就在nacos-server的日志里搜一下NullPointerException

[wangpin1997]

我看了你们的聊天，我也是这个问题，然后我查看了你说的对应位置的的文件，内容如下

[wangpin1997]

然后我通过断点调试之后，我发现，程序里边拿到的namespace是系统默认生成的，不是我集群后数据库的那个，我不知道问题是不是出在这，希望能帮忙解决一下，方法调用，到这个init（）方法这里就没有发现其他地方调用了

[nkorange]

@wangpin1997 你的是另外一个问题，你需要看一下Raft集群是否选举成功，可以看下控制台上 集群管理->节点列表。

[besthanliu]

这个文件里面有 naming-server.log

[nkorange]

这个文件里面有 naming-server.log

你这个有NullPointer异常的机器，应该是cluster.conf配置有问题，执行下面的url看看和其他Nacos Server返回的是否一样：

curl '127.0.0.1:8848/nacos/v1/ns/operator/servers?healthy=true'

[besthanliu]

确实有一台机器没开,这个会影响到整个集群吗,我尝试下开了看看

[besthanliu]

现在两台机器都有开,还是一样.都能正常登录,还是一样,说不在服务列表 naming-server.log

[besthanliu]

[besthanliu]

naming-server.log

[besthanliu]

[besthanliu]

同时发现,启动集群模式成功,无法发现其他节点,集群 模式我之前在同一台机器不同端口上试过是可以的. 另外回到主题的问题上,即便挂了一台,我感觉也不至于让客户端不能连上直接报错的啊

[nkorange]

同时发现,启动集群模式成功,无法发现其他节点,集群 模式我之前在同一台机器不同端口上试过是可以的.

你本机IP172.18.137.185不在cluster.conf里，需要加到里面去。

另外回到主题的问题上,即便挂了一台,我感觉也不至于让客户端不能连上直接报错的啊

这个是可以优化一下，目前心跳是一个同步请求，可以改成异步请求。暂定1.2.0优化

[besthanliu]

关于:你本机IP172.18.137.185不在cluster.conf里，需要加到里面去。

这个问题解决了,其实算是一个bug.如上图我配的全是外网ip,nacos会自己找它们内网ip,关键这样一来,回到配置里,自然不存在172.18.137.185这个ip.

我百度了一下,人家是这么说的. https://www.wandouip.com/t5i278697/ 外网那个不灵活我就没用了,全部用回内网 ip.

最后全部节点启动完成之后,主题的问题也不存在了,可以正常使用.这边问一下,集群情况下都会这样吗?如果存在十来个节点,不会挂了一个就整个集群客户端异常吧,那不太好

[besthanliu]

最后,非常感谢你的耐心回答,祝nacos项目越来越强

悲催发现一样的问题，那几个自动生成的ip名称报错导致，而自动添加是因为不注意在其他配置中copy多了个label。。。

也是碰到相同的问题。把discovery版本改成2.2.3.RELEASE解决的。

com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery 2.2.3.RELEASE

[cheungjingyu]

问题解决了吗，我也碰到了同样的问题，项目启动的时候注册成功了。

是ip地址问题，nacos在集群模式下会自动在nacos/conf/cluster.conf中加入本实例的ip地址和端口，如果我们自己想在cluster.conf中配集群ip的话，会和自动加入的ip冲突。 所以不要自己配，把所有所有自动加入的ip放到各个nacos实例的cluster.conf中就行了

建议优化一下。
