## 1.问题描述 ##

第一次使用nacos，使用的是当前最新版2.2.1，按照[官网][Link 1]的启动指令，结果启动失败：  
指令：

startup.cmd -m standalone

报错有很多，其中一段是：

> Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘basicAuthenticationFilter’ defined in class path resource \[com/alibaba/nacos/prometheus/filter/PrometheusAuthFilter.class\]: Unsatisfied dependency expressed through method ‘basicAuthenticationFilter’ parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘nacosAuthConfig’ defined in URL \[jar:file:/E:/env/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-plugin-default-impl-2.2.1.jar!/com/alibaba/nacos/plugin/auth/impl/NacosAuthConfig.class\]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘tokenManagerDelegate’: Unsatisfied dependency expressed through field ‘jwtTokenManager’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘jwtTokenManager’ defined in URL \[jar:file:/E:/env/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-plugin-default-impl-2.2.1.jar!/com/alibaba/nacos/plugin/auth/impl/token/impl/JwtTokenManager.class\]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate \[com.alibaba.nacos.plugin.auth.impl.token.impl.JwtTokenManager\]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: the length of secret key must great than or equal 32 bytes; And the secret key must be encoded by base64.Please see https://nacos.io/zh-cn/docs/v2/guide/user/auth.html

## 2.查找原因 ##

可以看到上述报错红色部分说：必须有一个长度大于等于32bytes的secret key，根据给出的网址https://nacos.io/zh-cn/docs/v2/guide/user/auth.html可以看到，nacos没有给出secret.key的默认值了，所以需要自己配置一下。

## 3.解决方式 ##

### 3.1 进入nacos的conf文件夹，找到application.properties配置文件，在配置文件中找到secret.key； ###

### 3.2 使用随机字符串生成工具（我用的是[这个][Link 2]），生成一段大于等于32位的随机字符作为key写在配置文件，保存后重启nacos即可。 ###
