Nacos startup无反应，启动报错的解决办法

向右看齐 2022-09-14 09:27 497阅读 0赞

今天在运行Nacos的时候遇见了点问题，记录一下。

我的系统是win11，运行的Nacos版本是 2.0.3  
**[https://github.com/alibaba/nacos/releases/tag/2.0.3][https_github.com_alibaba_nacos_releases_tag_2.0.3]**

## 运行startup.cmd 无反应 ##

刚开始直接双击 **startup.cmd** 运行什么反应都没有，也不知道是什么原因。于是就尝试在命令行执行 **startup.cmd** 给出了以下提示。

告知我们需要设置 JAVA\_HOME 环境变量，并且需要jdk8或以后的64位的版本。

知道什么原因就好办了，我本地安装的就是jdk8的64位，那我只需要设置下JAVA\_HOME环境变量就可以了。

如下，如果只设置系统变量后运行还是报错，建议在用户变量中也设置一下再试试。

设置好后再运行看一看：

这个时候可以运行了，但是运行报错了

## nacos is starting with cluster ##

报错信息如下

原因是2.0.3版本默认是以集群的模式去运行的，而我们本地并没有相关配置，我们只需要用单机模式去运行即可。

解决办法很简单，我们只需要修改一下 **startup.cmd** 里的代码配置即可。

右键 **startup.cmd** 选择编辑，反正能用编辑器打开就行。如下图

可以看到默认的配置是 `set MODE="cluster"`

我们将其改成 `set MODE="standalone"`即可。

修改后保存，重新运行再看一下。

可以看到，正常运行了。

用户名和密码默认都是 **nacos**

可以看到，正常登录成功了。
