https://blog.csdn.net/qq_58959857/article/details/132538948

 

启动：

startup.cmd -m standalone
使用cmd命令启动时，前面要加上 “ .\ ” 不然就会出现以上问题：.\startup.cmd -m standalone

 

======================nacos常见错误======================

1.问题：Nacos拉取的源码本地用idea启动不了，报错：

　　Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat

解决：

　　首先确认配置文件是否正确：application.properties

　　spring.datasource.platform=mysql
　　db.num=1
　　db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8
　　db.user=root
　　db.password=123456

　　其次：修改idea配置，添加： -Dnacos.standalone=true 再次启动试一试。

 2. nacos2.2.3源码修改适配人大金仓推荐博客连接：

（nacos2.2.3多数据源适配，包括对达梦、kingbase等国产数据库适配）

那就是查询配置列表的接口没查出来数据，你可以调试一下你修改的源码，找到这个类：ConfigController.searchConfig 这个方法，它最终会调用BaseConfigInfoMapper.findConfigInfo4PageFetchRows拿到查询page的sql，你可以本地调试拿到这个sql去数据库客户端跑一下能不能查出数据,我想大概率跟你kingbase的版本有关，因为kingbase的版本之间差异很大，导致字段大小写，驼峰等都会有差异，你先调试看看

 4. nacos 启动报错：com.mysql.cj.exceptions.UnableToConnectException: Public Key Retrieval is not allowed

　　解决：    找到nacos安装目录下的conf目录,修改application.properties文件，在连接URL后面添加参数：allowPublicKeyRetrieval=true即可。
