1.1)问题描述

环境描述

• nacos的版本：2.0.3
• contos7系统
• mysql版本：5.7.29

问题场景描述

mysql与nacos都配置好了，docker都正常启动。nacos在启动的时候报错！

2024-05-02 14:34:55,130 ERROR Startup errors : 

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'memoryMonitor' defined in URL [jar:file:/home/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-config-2.0.3.jar!/com/alibaba/nacos/config/server/monitor/MemoryMonitor.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'asyncNotifyService': Unsatisfied dependency expressed through field 'dumpService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'externalDumpService': Invocation of init method failed; nested exception is ErrCode:500, ErrMsg:Nacos Server did not start because dumpservice bean construction failure :
No DataSource set

主要报错原因

No DataSource set

1.2)问题排查

• 查看mysql的容器信息。

docker inspect mysql

• 查看docker的网络列表

docker network ls

• 查看nacos的网络

docker inspect nacos

1.3)问题原因

• mysql容器与nacos容器不在一个网络中。所以：nacos无法连接到mysql的数据库。

1.4)解决

在docker-compose文件添加一个属性。设置nacos与mysql在同一个网络当中。

 network_mode: base-service_default

2)2.0.3版本问题

2.1)问题描述

原来的依赖。正常启动。

       <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>

添加nacos的客户端jar后。版本：2.1.2【启动报错】

nacos的服务端版本：2.0.3。

springboot版本：2.3.4.RELEASE

springcloud版本：2.2.1.RELEASE，Hoxton.SR8

主要报错信息：why？？？【得去看源码了】

Server check fail, please check server 10.47.80.251 ,port 9848 is available , error ={}

说：服务器检查失败，请检查服务器10.47.80.251，端口9848可用，错误=｛｝

2.2)解决

1.X 版本最新java SDK为 1.4.4版本

        <!--nacos配置中心客户端-->
        <dependency>

nacos常用启动命令【docker】

• 启动nacos

 docker-compose up -d nacos-standalone

• 查看nacos的日志

 docker logs -f nacos
