解决Nacos2.2.1启动报错
报错原因
Caused by: 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 http://xxx....
Caused by: java.lang.IllegalArgumentException:
The specified key byte array is x bits which is not secure enough for any JWT HMAC-SHA algorithm.
The JWT JWA Specification (RFC 7518, Section 3.2) states that keys used with HMAC-SHA algorithms MUST have a size >= 256 bits (the key size must be greater than or equal to the hash output size).
原因总结
很明显，报错原因是secret key参数 长度不够 打开nacos文件夹 -> conf -> application.properties 找到以下配置： nacos.core.auth.plugin.nacos.token.secret.key= 在后面添加随机参数作为nacos的加密密钥， 规则是加密密钥长度 >=256 bits 或者 >= 32 bytes
我添加了50位英文、数字成功运行
执行
startup.cmd -m standalone
最终结果
成功点亮
