Spirngboot实现Nacos作为配置中心
一、Nacos（Nacos官方文档）
Nacos是阿里旗下的一款开源软件，支持服务注册与发现、配置管理以及微服务管理的组件。Nacos的目标是为了取代过去常用的注册中心（Zookeeper、Eureka等），以及配置中心（Spring Cloud Config等）。Nacos集成了注册中心和配置中心的功能。
基于此，虽然是SpirngBoot项目，服务注册与发现用不上，但是可以使用Nacos配置中心的功能，对项目的配置文件进行动态管理。
二、nacos依赖
<!-- nacos配置中心依赖 -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
springcloud相关依赖如下：
<!-- spring-cloud-alibaba依赖库 -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>${spring-cloud-alibaba.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<spring-cloud-alibaba.version>2.2.6.RELEASE</spring-cloud-alibaba.version>
注意：springcloud-alibaba依赖版本需和nacos版本对应。（版本对应关系）
附：
注册中心依赖如下：
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
注意：查询资料时发现有如下问题：
SpringBoot项目bootstrap.yml配置文件不加载：
bootstrap.yml需要引入springcloud的包才会加载。
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-context</artifactId>
<version>${spring-cloud-context.version}</version>
</dependency>
此问题我并没有遇到，如遇到此问题可按如上方式进行尝试解决。
三、Nacos搭建
1、Nacos下载。去到官网下载各个版本的压缩包。下载地址。我用的是1.4.2版本。最新版本目前为2.0.3。
本地：下载.zip文件解压到本地使用。Linux：下载.tar.gz文件部署到Linux环境解压使用。
如何启动Nacos服务查询官方文档。上面都有说明。
2、搭建测试环境集群。
首先建立三台测试服务器。如192.168.1.1，192.168.1.2， 192.168.1.3。
先将下载好的nacos-server-1.4.2.tar.gz文件上传到三台测试服务器上。
unzip nacos-server-1.3.0.zip 或者 tar -xvf nacos-server-1.3.0.tar.gz解压上传的压缩文件。
解压之后，进到conf文件夹下，有一个cluster.conf.example文件。可以cp cluster.conf.example cluster.conf将原文件备份保存，然后创建一个新的cluster.conf文件使用。
ps：此处如不做备份，则使用cluster.conf文件需要将原来的.example后缀删除使用.conf文件。
cat cluster.conf命令查看此文件，在此文件中，请每行配置成ip:port形式。如：
# ip:port
192.168.1.1:8848
192.168.1.2:8848
192.168.1.3:8848
3、启动服务器。
启动服务器之前还有一步操作，需要执行一个使用外置数据源的sql脚本，此脚本在下载的nacos压缩包中自带，直接建立数据库执行就好。
执行脚本结束后，需要修改conf文件夹下的application.properties配置文件。放开如下注释。
修改mysql数据库配置。
此时直接执行sh.startup.sh启动命令会报如下错误。
解决方案。用vi命令配置jdk。
此时配置添加完成，执行启动命令，执行成功。
4、相关配置。
下载下来的nacos默认此处为false。我们要将此处权限修改为true。如果为false则登录nacos时无需验证用户名和密码。
此处可以配置为false。nacos增长的日志太快，且有大部分是无效日志。如需要则打开。
修改nacos-logback.xml,将没用的日志注释掉，要不日志太多了。

Nacos集群部署完成。登录格式：域名+/nacos 登录。管理员用户名密码默认都为nacos。进入可视化界面可进行修改。

四、代码配置
本项目结构如图。
在父依赖中配置profiles做环境区分。
<!--开发环境-->
<profile>
<id>dev</id>
<properties>
<profileActive>dev</profileActive>
<profileActiveNacosServerAddr>192.168.1.1:8848,192.168.1.2:8848,192.168.1.3:8848</profileActiveNacosServerAddr>
<profileNacosNameSpace>lmes-dev</profileNacosNameSpace>
<profileNacosConfigNameSpace>生成的namespaceid</profileNacosConfigNameSpace>
<profileNacosUsername>用户名</profileNacosUsername>
<profileNacosPassword>密码</profileNacosPassword>
</properties>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
</profile>
每个服务中需添加bootstrap.yml文件。
配置如下：
spring:
application: #微服务名称
name: lmes-agentmanagement
main:
allow-bean-definition-overriding: true -----不知道干啥的 之后有需要可进行分析
cloud:
nacos:
username: @profileNacosUsername@

父依赖pom文件中还需要添加如下配置：
<build>
<resources>
<resource>
<filtering>true</filtering> ----- true表示文件中可以获取到pom文件中的配置。
<directory>src/main/resources</directory> -----作用域到这个文件夹下面的文件
<excludes>
<exclude>config/application*.yml</exclude> -----exclude排除某些文件 include包括某些文件
</excludes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<layout>JAR</layout>
<finalName>${project.name}-server</finalName>
<outputDirectory>../install/servers/${project.artifactId}</outputDirectory>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
检测bootstrap.yml文件有没有成功加载pom文件中配置的数据：
idea----clean----install
去看项目中target下的bootstrap有没有印上相应的值。
五、发布测试环境
打包成功后会在install中生成对应服务的jar包。
把生成的jar包放到对应的服务器上。
操作MobaXterm。
先进入到对应的服务器，ps -ef| grep java 查看存活线程。
找到对应的服务进入到对应目录下面。
找到启动文件。cat查看启动文件。没有kill命令需要执行 kill -9 命令杀掉线程重新发布。 启动文件中可能会有$1 $2 这种参数，需注意。
至此，nacos配置中心部署完成。
