Nacos启动报错

Nacos启动报错问题的解决方案

nacos官网得知环境要求为jdk1.8+、maven3.2.x+，为了避免采坑，版本尽量使用官网推荐的

直接上报错，如下

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘instanceOperatorClientImpl’ defined in URL [jar:file:/G:/ad_app/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-naming-2.1.0.jar!/com/alibaba/nacos/naming/core/InstanceOperatorClientImpl.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘clientOperationServiceProxy’ defined in URL [jar:file:/G:/ad_app/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-naming-2.1.0.jar!/com/alibaba/nacos/naming/core/v2/service/ClientOperationServiceProxy.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘persistentClientOperationServiceImpl’ defined in URL [jar:file:/G:/ad_app/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-naming-2.1.0.jar!/com/alibaba/nacos/naming/core/v2/service/impl/PersistentClientOperationServiceImpl.class]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.alibaba.nacos.naming.core.v2.service.impl.PersistentClientOperationServiceImpl]: Constructor threw exception; nested exception is java.lang.UnsatisfiedLinkError: C:\Users\Administrator\AppData\Local\Temp\librocksdbjni7299637627324802538.dll: Can’t find dependent libraries

原因分析：

系统缺少 vc++ 2015

解决方案：

1.下载地址：传送门. 下载后直接安装即可，安装完成后重启nacos 。
2.nacos默认启动为集群模式cluster,需要在启动命令后添加startup.cmd -m standalone,或者修改.bat文件
3.nacos所在路径不能有中文 。
