访问页面地址：
http://192.168.2.209:8848/nacos/index.html
发现360极速浏览器和Edge都是一片空白
后知后觉要切换模式，但是我也不明白这是为什么
然后就可以看到登录首页了
账号密码都是nacos
将服务注册到Nacos中
首先在总项目的父工程中配置springCloudAlibaba的依赖：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.itcast.demo</groupId> <artifactId>cloud-demo</artifactId> <version>1.0</version> <modules> <module>user-service</module> <module>order-service</module> <module>eureka-server</module> <module>feign-api</module> <module>gateway</module> </modules> <packaging>pom</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.9.RELEASE</version> <relativePath/> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <spring-cloud.version>Hoxton.SR10</spring-cloud.version> <mysql.version>5.1.47</mysql.version> <mybatis.version>2.1.1</mybatis.version> </properties> <dependencyManagement> <dependencies> <!-- springCloud --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> <!--nacos的管理依赖--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.2.5.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <!-- mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>${mybatis.version}</version> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> </dependencies> </project>
需要注册的服务都把Eureka组件替换成Nacos组件：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>cloud-demo</artifactId> <groupId>cn.itcast.demo</groupId> <version>1.0</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>order-service</artifactId> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> </dependency> <!--eureka客户端依赖--> <!--<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency>--> <!-- nacos客户端依赖包 --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <!--feign客户端依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> <!--引入HttpClient依赖--> <dependency> <groupId>io.github.openfeign</groupId> <artifactId>feign-httpclient</artifactId> </dependency> <!--引入feign的统一api--> <dependency> <groupId>cn.itcast.demo</groupId> <artifactId>feign-api</artifactId> <version>1.0</version> </dependency> </dependencies> <build> <finalName>app</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
第三步，被注册的服务还需要配置上nacos的地址信息：
server: port: 8088 spring: datasource: url: jdbc:mysql://mysql:3308/cloud_order?useSSL=false username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver application: name: orderservice cloud: nacos: server-addr: nacos:8848 # nacos服务地址 # discovery: # namespace: 4d6ce343-9e1b-44df-a90f-2cf2b6b3d177 # dev环境 # ephemeral: false # 是否是临时实例 mybatis: type-aliases-package: cn.itcast.user.pojo configuration: map-underscore-to-camel-case: true logging: level: cn.itcast: debug pattern: dateformat: MM-dd HH:mm:ss:SSS #eureka: # client: # service-url: # eureka的地址信息 # defaultZone: http://127.0.0.1:10086/eureka userservice: ribbon: NFLoadBalancerRuleClassName: com.alibaba.cloud.nacos.ribbon.NacosRule # 负载均衡规则 ribbon: eager-load: enabled: true # 开启饥饿加载 clients: # 指定饥饿加载的服务名称 - userservice feign: httpclient: enabled: true # 支持HttpClient的开关 max-connections: 200 # 最大连接数 max-connections-per-route: 50 # 单个路径的最大连接数
Nacos服务分级存储模型？
保证服务安全
解决服务跨集群调用
一级 服务
二级 集群
三级 实例
配置集群，多实例启动以模拟集群
server: port: 8081 spring: datasource: url: jdbc:mysql://mysql:3308/cloud_user?useSSL=false username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver shardingsphere: sharding: default-database-strategy: tables: cloud: nacos: server-addr: localhost:8848 discovery: cluster-name: HZ # 集群名称 HZ / SH mybatis: type-aliases-package: cn.itcast.user.pojo configuration: map-underscore-to-camel-case: true logging: level: cn.itcast: debug pattern: dateformat: MM-dd HH:mm:ss:SSS #eureka: # client: # service-url: # eureka的地址信息 # defaultZone: http://127.0.0.1:10086/eureka pattern: name: 本地环境local
NacosRule负载均衡

权重配置调整：
权重调整在 0 ~ 1 范围内
环境隔离
nameSpace > group > service/data
https://www.bilibili.com/video/BV1LQ4y127n4?p=22
标记为临时服务实例，Nacos检测此服务发现不健康时，将直接从注册中心中删除
配置为是否是临时实例：
server: port: 8088 spring: datasource: url: jdbc:mysql://mysql:3308/cloud_order?useSSL=false username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver application: name: orderservice cloud: nacos: server-addr: nacos:8848 # nacos服务地址 # discovery: # namespace: 4d6ce343-9e1b-44df-a90f-2cf2b6b3d177 # dev环境 # ephemeral: false # 是否是临时实例 mybatis: type-aliases-package: cn.itcast.user.pojo configuration: map-underscore-to-camel-case: true logging: level: cn.itcast: debug pattern: dateformat: MM-dd HH:mm:ss:SSS #eureka: # client: # service-url: # eureka的地址信息 # defaultZone: http://127.0.0.1:10086/eureka userservice: ribbon: NFLoadBalancerRuleClassName: com.alibaba.cloud.nacos.ribbon.NacosRule # 负载均衡规则 ribbon: eager-load: enabled: true # 开启饥饿加载 clients: # 指定饥饿加载的服务名称 - userservice feign: httpclient: enabled: true # 支持HttpClient的开关 max-connections: 200 # 最大连接数 max-connections-per-route: 50 # 单个路径的最大连接数
Nacos配置管理：
配置信息 统一管理
配置信息 热更新
配置信息 可共享
搭建Nacos集群
https://www.bilibili.com/video/BV1LQ4y127n4?p=25
配置管理：
引入Nacos配置管理客户端依赖：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>cloud-demo</artifactId> <groupId>cn.itcast.demo</groupId> <version>1.0</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>user-service</artifactId> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> </dependency> <!--eureka客户端依赖--> <!--<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency>--> <!-- nacos客户端依赖包 --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <!--nacos的配置管理依赖--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId> </dependency> </dependencies> <build> <finalName>app</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
配置引导文件，bootstrap.yml
spring:

热更新实现
第一种 @Value + @RefreshScope
package cn.itcast.user.web; import cn.itcast.user.config.PatternProperties; import cn.itcast.user.pojo.User; import cn.itcast.user.service.UserService; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; @Slf4j @RestController @RequestMapping("/user") // @RefreshScope public class UserController { @Autowired private UserService userService; // @Value("${pattern.dateformat}") // private String dateformat; @Autowired private PatternProperties properties; @GetMapping("prop") public PatternProperties properties(){ return properties; } @GetMapping("now") public String now(){ return LocalDateTime.now().format(DateTimeFormatter.ofPattern(properties.getDateformat())); } /** * 路径： /user/110 * * @param id 用户id * @return 用户 */ @GetMapping("/{id}") public User queryById(@PathVariable("id") Long id, @RequestHeader(value = "Truth", required = false) String truth) { System.out.println("truth: " + truth); return userService.queryById(id); } }
第二种热更新配置方式：
package cn.itcast.user.config; import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; @Data @Component @ConfigurationProperties(prefix = "pattern") public class PatternProperties { private String dateformat; private String envSharedValue; private String name; }
多环境配置共享
集群搭建 ：
图的意思是注册的服务先经过Nginx反向代理和负载均衡之后分配到集群的其中一个，再找到对应配置

1、解压Nacos （全新未作改动的）
2、复制cluster.conf.example 并将副本重命名为 cluster.conf
配置集群节点的IP和端口：
127.0.0.1:8845 127.0.0.1.8846 127.0.0.1.8847
3、然后配置MySQL的信息
application.properties文件内容：
spring.datasource.platform=mysql db.num=1 db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC db.user.0=root db.password.0=123
4、配置完之后将Nacos复制三份
分别配置上各自的端口号：
nacos1: server.port=8845 nacos2: server.port=8846 nacos3: server.port=8847
然后启动Nacos[运行Startup.cmd]
5、配置Nginx，并配置反向代理
解压Nginx, 修改conf/nginx.conf文件
upstream nacos-cluster { server 127.0.0.1:8845; server 127.0.0.1:8846; server 127.0.0.1:8847; } server { listen 80; server_name localhost; location /nacos { proxy_pass http://nacos-cluster; } }
而后在浏览器访问：http://localhost/nacos
最后在服务的启动配置文件中【application.yml】或者【bootstrap.yml】：
spring: cloud: nacos: server-addr: localhost:80 # Nacos地址
