win11中nacos3.0.1.1启动问题

问题一：启动方式不对

nacos3.0.1.1默认启动方式是集群

单机模式启动要修改bin目录下启动文件 startup.cmd，把mode改为standalone,

 问题二：JDK版本不正确，nacos3.0.1.1要求jdk版本17以上。

ERROR: Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk17 or later is better! !!

 请在您的环境中设置JAVA_HOME变量，我们需要JAVA（x64）！jdk17或更高版本更好！！

意思是说我们的java变量没有配置或者jdk版本过低，但是我用的是新下载的最高的版本，然后再排查java变量配置发现应该是启动脚本里面没有配置java变量。

所以，我赶紧去看了我安装的Jdk

 jdk17下载：Java Downloads | Oracle

 解压，配置JAVA_HOME环境变量就可以了

问题三：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'defaultAuthenticationManager' defined in class path resource

出现这个问题是由于nacos3的鉴权引起的，nacos3默认开启鉴权，而我在一开始启动设置鉴权密钥的时候随便输入了秘钥，没有设置Base64编码的字符串，

`nacos.core.auth.plugin.nacos.token.secret.key` is missing, please set with Base64 string: ${your_input_token_secret_key}
nacos.core.auth.plugin.nacos.token.secret.key` Updated:
----------------------------------
`nacos.core.auth.server.identity.key` is missing, please set: ${your_input_server_identity_key}
`nacos.core.auth.server.identity.key` Updated:
----------------------------------
`nacos.core.auth.server.identity.value` is missing, please set: ${your_input_server_identity_key}
`nacos.core.auth.server.identity.value` Updated:
----------------------------------

 

需要在使用用户名和密码登录之后，才能正常使用nacos。

开启鉴权之前，application.properties中的配置信息为：

### If turn on auth system:
nacos.core.auth.enabled=false

开启鉴权之后，application.properties中的配置信息为：

### If turn on auth system:
nacos.core.auth.system.type=nacos
nacos.core.auth.enabled=true

 

开启鉴权之后，你可以自定义用于生成JWT令牌的密钥，application.properties中的配置信息为：

注意：

1. 文档中提供的密钥为公开密钥，在实际部署时请更换为其他密钥内容，防止密钥泄漏导致安全风险。
2. 在2.2.0.1版本后，社区发布版本将移除以文档如下值作为默认值，需要自行填充，否则无法启动节点。
3. 密钥需要保持节点间一致，长时间不一致可能导致403 invalid token错误。

自定义密钥时，推荐将配置项设置为Base64编码的字符串，且原始密钥长度不得低于32字符。例如下面的的例子：

### The default token(Base64 String):

nacos.core.auth.default.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=

 

### 2.1.0 版本后

nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=

注意：鉴权开关是修改之后立马生效的，不需要重启服务端。

最后nacos启动成功，可以访问 http://192.168.1.12:8080/index.html，其中ip是本机电脑的ip，在登录页面输入你设置的用户名和密码就可访问nacos。
