nacos是源自阿里旗下的一款开源软件，支持服务治理以及配置管理，部署支持单机模式以及集群，存储支持derby以及mysql。

本文介绍的是nacos 单机部署，mysql存储配置

环境搭建：

1.在github下载nacos-server环境，[https://github.com/alibaba/nacos/releases][https_github.com_alibaba_nacos_releases]

2.修改配置，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 2][]

3.这样一个单机版的nacos config环境就搭建好了，直接双击startup.cmd启动即可，启动后的配置页面：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 4][]

4.客户端配置，客户端是spring-cloud项目，加入依赖：

<dependency>  
            <groupId>org.springframework.cloud</groupId>  
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>  
            <version>0.1.2.RELEASE</version>  
        </dependency>

5.在bootstrap.properties加入下面配置：

\#nacos config配置https://github.com/alibaba/spring-cloud-alibaba/wiki/Nacos-config  
spring.cloud.nacos.config.server-addr=127.0.0.1:8848  
spring.cloud.nacos.config.file-extension=properties  
\#默认为Public命名空间,可以省略不写  
spring.cloud.nacos.config.namespace=  
spring.cloud.nacos.config.group=microservice

6.在配置需要更新的Component注解类上面加上@RefreshScope注解：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 5][]

7.至此结束，在写一个controller测试下就可以了：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 6][]
