docker-compose安装nacos

文章目录

一、安装nacos

安装文档：https://mrbird.cc/Spring-Cloud-Alibaba-Nacos%E6%B3%A8%E5%86%8C%E4%B8%AD%E5%BF%83.html

docker-compose安装nacos

创建文件夹：/opt/docker-file/nacos

1.docker-compose.yml

version:"3"services:nacos:image: nacos/nacos-server:v2.1.0
    container_name: nacos
    environment:# 支持主机名可以使用hostname,否则使用ip，默认ip- PREFER_HOST_MODE=ip
      # 单机模式- MODE=standalone
      # 数据源平台 支持mysql或不保存empty- SPRING_DATASOURCE_PLATFORM=mysql
      # mysql配置，!!!attention必须是mysql所在主机IP#- MYSQL_SERVICE_HOST=192.168.0.123#- MYSQL_SERVICE_PORT=3306#- MYSQL_SERVICE_USER=root#- MYSQL_SERVICE_PASSWORD=123456#- MYSQL_SERVICE_DB_NAME=nacosvolumes:- ./logs:/home/nacos/logs
      - ./conf:/home/nacos/conf
    ports:- 8848:8848restart: always

创建log日志目录及配置文件目录：

mkdir-p /opt/docker-file/nacos/logs
mkdir-p /opt/docker-file/nacos/conf

将application.properties文件复制到/opt/docker-file/nacos/conf目录下

server.servlet.contextPath=/nacos
server.port=8848
spring.datasource.platform=mysql
# 数据库数量
db.num=1
db.url.0=jdbc:mysql://192.168.229.199:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root2
db.password=123456

3.docker-compose 构建运行

[root@localhost nacos]# docker-compose up -d[+] Running 1/1
 ⠿ Container nacos  Started

4.检查nacos日志

docker logs -f nacos

需要在conf目录准备log文件:nacos-logback.xml

<?xml version="1.0" encoding="UTF-8"?><configurationdebug="false"scan="true"scanPeriod="1 seconds"><contextName>logback</contextName><propertyname="log.path"value="/home/nacos/logs/logback.log"/><appendername="console"class="ch.qos.logback.core.ConsoleAppender"><!-- <filter class="com.example.logback.filter.MyFilter" /> --><filterclass="ch.qos.logback.classic.filter.ThresholdFilter"><level>ERROR</level></filter><encoder><pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n
            </pattern></encoder></appender><appendername="file"class="ch.qos.logback.core.rolling.RollingFileAppender"><file>${log.path}</file><rollingPolicyclass="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><fileNamePattern>${log.path}.%d{yyyy-MM-dd}.zip</fileNamePattern></rollingPolicy><encoder><pattern>%date %level [%thread] %logger{36} [%file : %line] %msg%n
            </pattern></encoder></appender><rootlevel="debug"><appender-refref="console"/><appender-refref="file"/></root><loggername="com.example.logback"level="warn"/></configuration>

继续查看nacos错误日志

如连接不上数据库，就是数据库账号密码没有配对。

6.测试访问：

地址：192.168.229.199:49155/nacos/#/login
账号：nacos
密码：nacos

TODO:

打包成新的镜像放在本地仓库，下次可以直接用

二、nacos为注册中心：项目测试

nacos与springcloud与springcloudalibaba版本对照
在这里插入图片描述
nacos版本：v2.1.0
springboot版本：

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.8.RELEASE</version><relativePath/><!-- lookup parent from repository --></parent>

springcloudalibaba与springcloud版本：

<properties><java.version>1.8</java.version><spring-cloud.version>Greenwich.RELEASE</spring-cloud.version><com-alibaba-cloud.version>2.1.0.RELEASE</com-alibaba-cloud.version></properties>

1.新建maven项目：

在这里插入图片描述
父：spring-cloud-alibaba-nacos-register
子：consumer，provider

2.配置pom.xml

spring-cloud-alibaba-nacos-register

<?xml version="1.0" encoding="UTF-8"?><projectxmlns="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>cc.mrbird</groupId><artifactId>spring-cloud-alibaba-nacos-register</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><modules><module>provider</module><module>consumer</module></modules><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.8.RELEASE</version><relativePath/><!-- lookup parent from repository --></parent><properties><java.version>1.8</java.version><spring-cloud.version>Greenwich.RELEASE</spring-cloud.version><com-alibaba-cloud.version>2.1.0.RELEASE</com-alibaba-cloud.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-nacos-discovery</artifactId></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${com-alibaba-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement></project>

provider

<?xml version="1.0" encoding="UTF-8"?><projectxmlns="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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>cc.mrbird</groupId><artifactId>spring-cloud-alibaba-nacos-register</artifactId><version>1.0-SNAPSHOT</version><relativePath>../pom.xml</relativePath></parent><artifactId>provider</artifactId><name>provider</name><description>服务提供端</description><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

consumer

<?xml version="1.0" encoding="UTF-8"?><projectxmlns="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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>cc.mrbird</groupId><artifactId>spring-cloud-alibaba-nacos-register</artifactId><version>1.0-SNAPSHOT</version><relativePath>../pom.xml</relativePath></parent><artifactId>consumer</artifactId><name>consumer</name><description>服务消费端</description><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

3.配置application.properties

provider

server.port=8001
spring.application.name=nacos-producer
spring.cloud.nacos.discovery.server-addr=192.168.229.199:8848
management.endpoints.web.exposure.include=*

comsumer

server.port=8002
spring.application.name=nacos-consumer
spring.cloud.nacos.discovery.server-addr=192.168.229.199:8848
management.endpoints.web.exposure.include=*

4.激活服务发现客户端

启动类加注解@EnableDiscoveryClient

5.编写controller

provider

packagecc.mrbird.provider.controller;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.PathVariable;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("provide")publicclassHelloController{@GetMapping("{message}")publicStringhello(@PathVariableString message){returnString.format("hello %s", message);}}

consumer

packagecc.mrbird.consumer.controller;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.cloud.client.ServiceInstance;importorg.springframework.cloud.client.loadbalancer.LoadBalancerClient;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.PathVariable;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;importorg.springframework.web.client.RestTemplate;@RestController@RequestMapping("consume")publicclassConsumeController{@AutowiredprivateLoadBalancerClient loadBalancerClient;@AutowiredprivateRestTemplate restTemplate;@GetMapping("hello/{message}")publicStringhello(@PathVariableString message){ServiceInstance serviceInstance = loadBalancerClient.choose("nacos-producer");String path =String.format("http://%s:%s/provide/%s", serviceInstance.getHost(), serviceInstance.getPort(), message);String result = restTemplate.getForObject(path,String.class);returnString.format("%s from %s %s", result, serviceInstance.getHost(), serviceInstance.getPort());}}

6.增加远程调用配置

consumer

packagecc.mrbird.consumer.configure;importorg.springframework.context.annotation.Bean;importorg.springframework.context.annotation.Configuration;importorg.springframework.web.client.RestTemplate;@ConfigurationpublicclassConsumerConfigure{@BeanpublicRestTemplaterestTemplate(){returnnewRestTemplate();}}

7.启动后查看nacos网页端

http://192.168.229.199:8848/nacos/#/serviceManagement
如图：
在这里插入图片描述

8.访问地址

服务提供者：localhost:8001/provide/nacos
服务消费者：localhost:8002/consume/hello/nacos

9.测试消费端负载均衡

启动两个provider：
localhost:8001/provide/nacos
localhost:8009/provide/nacos

在这里插入图片描述
在这里插入图片描述

三.nacos配置中心和注册中心：项目测试

java项目如果启动了配置中心，在项目不重启的情况下，可以远程动态的修改配置信息

1.新建maven项目

在spring-cloud-alibaba-nacos-register项目下新建子项目config

2.配置子项目pom.xml

<?xml version="1.0" encoding="UTF-8"?><projectxmlns="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>spring-cloud-alibaba-nacos-register</artifactId><groupId>cc.mrbird</groupId><version>1.0-SNAPSHOT</version><relativePath>../pom.xml</relativePath></parent><modelVersion>4.0.0</modelVersion><artifactId>config</artifactId><description>配置服务</description><dependencies><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-nacos-config</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

3.配置bootstrap.properties文件

必须是bootstrap.properties文件，不然加载不到

server.port=8102
spring.cloud.nacos.config.server-addr=192.168.229.199:8848
#spring.cloud.nacos.config.file-extension=properties
spring.application.name=nacos-config-example

spring.cloud.nacos.discovery.server-addr=192.168.229.199:8848
management.endpoints.web.exposure.include=*

4.激活服务发现客户端

packagecc.mrbird.config;importorg.springframework.boot.SpringApplication;importorg.springframework.boot.autoconfigure.SpringBootApplication;importorg.springframework.boot.context.properties.EnableConfigurationProperties;@SpringBootApplication@EnableConfigurationPropertiespublicclassConfigApplication{publicstaticvoidmain(String[] args){SpringApplication.run(ConfigApplication.class, args);}}

5.编写controller

packagecc.mrbird.config.controller;importcc.mrbird.config.config.UserConfig;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.PathVariable;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("config")publicclassController{@AutowiredprivateUserConfig userConfig;@GetMapping("hello/{message}")publicStringsayHello(@PathVariableString message){returnthis.userConfig.getUsername()+ message +";"+this.userConfig.getAge();}}

6.编写bean，获取远程配置

packagecc.mrbird.config.config;importlombok.Data;importorg.springframework.boot.context.properties.ConfigurationProperties;importorg.springframework.boot.context.properties.EnableConfigurationProperties;importorg.springframework.context.annotation.Configuration;importorg.springframework.stereotype.Component;@ConfigurationProperties(prefix ="user")//@Component@Configuration@DatapublicclassUserConfig{privateString username;privateint age;}

7.在nacos服务端上增加配置

注意dataId的命名方式
在这里插入图片描述

8.启动config项目

没有报错，说明配置没有问题

9.访问controller

localhost:8102/config/hello/nacos

修改nacos服务端配置后再次访问：成功

四、整合gateway网关

1.添加依赖

注释web依赖
<!--        <dependency>--><!--            <groupId>org.springframework.boot</groupId>--><!--            <artifactId>spring-boot-starter-web</artifactId>--><!--        </dependency>--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-gateway</artifactId><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></exclusion></exclusions></dependency>

2.编写配置文件

spring:gateway:routes:-id: gateway-test  # 访问http://localhost:8801/gateway-test/test/index，会跳转到访问到 http://localhost:8802/gateway-test/test/index地址uri: lb://gateway-test
          order:0predicates:- Path=/gateway-test/**filters:- StripPrefix=1
            
management:endpoints:web:exposure:include:'*'

3.启动项目

4.如何测试网关是否拦截了目标服务器请求
