spring cloud alibaba 注册中心服务

1、从github下载nacos服务

https://github.com/alibaba/nacos/releases

2、解压启动

解压进入bin目录单例启动：cd nacos/bin

linux:sh startup.sh -m standalone
windows:cmd startup.cmd -m standalone

！！！假如报：ERROR read cluster conf fail 用bash startup.sh -m standalone命令执行。使用sh命令会报错，因而是因为startup.sh文件中的[[ ]] 的问题，sh命令并不能识别，只有bash才行。

3、客户端

添加依赖

<dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
</dependencies>
<dependencyManagement>
    <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2.2.3.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
    </dependencies>
</dependencyManagement>
