spring: application: name: dev eureka: client: service-url: defaultZone: http://本機(jī)ip地址:8761/eureka/ #注冊(cè)中心地址 register-with-eureka: false #表明該實(shí)例是否應(yīng)該與尤里卡服務(wù)器登記其信息被別人發(fā)現(xiàn)。在某些情況下,您不希望您的實(shí)例被發(fā)現(xiàn)而你想發(fā)現(xiàn)其他實(shí)例。默認(rèn)為true fetch-registry: false #表明這個(gè)客戶是否應(yīng)該從尤里卡服務(wù)器獲取尤里卡注冊(cè)表信息。默認(rèn)為true server: port: 8761
啟動(dòng)類添加 @EnableEurekaServer
客戶端：
主要依賴
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')application.yml 配置
eureka: client: service-url: defaultZone: http://eureka服務(wù)地址:8761/eureka/
啟動(dòng)類添加 @EnableDiscoveryClient （注冊(cè)中心通用客戶端注解）或 @EnableEurekaClient （只有eureka客戶端可用）
eureka（集群）
服務(wù)端
主要依賴
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')application.yml 配置
server: port: 8761 eureka: client: register-with-eureka: false fetch-registry: false server: enable-self-preservation: false #使用自我保護(hù)，默認(rèn)true peer-node-read-timeout-ms: 5000 #節(jié)點(diǎn)讀取超時(shí)時(shí)間，默認(rèn)200毫秒 --- spring: application: name: eureka1 profiles: eureka1 eureka: client: service-url: defaultZone: http://eureka2:8761/eureka/,http://eureka3:8761/eureka/ instance: hostname: eureka1 --- spring: application: name: eureka2 profiles: eureka2 eureka: client: service-url: defaultZone: http://eureka1:8761/eureka/,http://eureka3:8761/eureka/ instance: hostname: eureka2 --- spring: application: name: eureka3 profiles: eureka3 eureka: client: service-url: defaultZone: http://eureka1:8761/eureka/,http://eureka2:8761/eureka/ instance: hostname: eureka3
eureka.client.service-url.defaultZone 與 eureka.instance.hostsname eureka1、eureka2、eureka3 都再本機(jī)的 hosts 文件里事先寫好,
例如 eureka1 服務(wù)器上的hosts文件
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 eureka1
xxx.xxx.x.xx eureka2
xx.xxx.xxx.xx eureka3
啟動(dòng)類同樣是添加 @EnableEurekaServer 注意：如果運(yùn)行 jar 包時(shí)需要程序接收命令行參數(shù)，一定要再main方法的 SpringApplication.run() 方法 中傳入 args 參數(shù)
例如：
public static void main(String[] args) {
SpringApplication.run(QnbbsConsumer.class,args);
}如果不傳入的話在命令行輸入 java -jar xxx.jar --參數(shù)名=參數(shù)值 參數(shù)將不起作用從而影響你無法選擇寫好的環(huán)境配置
客戶端：
依賴跟單機(jī)的一樣
application.yml 配置
eureka: instance: prefer-ip-address: true #是否顯示ip ip-address: 本機(jī)ip #填寫本機(jī)ip地址 client: service-url: defaultZone: http://eureka1:8761/eureka/,http://eureka2:8761/eureka/，http://eureka3:8761/eureka/
啟動(dòng)類注解與單機(jī)版一樣
客戶端注冊(cè)一臺(tái)注冊(cè)中心，同時(shí)注冊(cè)到其他集群中說明成功！
eureka添加 spring-security 權(quán)限認(rèn)證
依賴
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')application.yml 配置

package com.iteng.eureka.security;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@EnableWebSecurity
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable(); // 關(guān)閉csrf
http.authorizeRequests().anyRequest().authenticated().and().httpBasic(); // 開啟認(rèn)證
}
}啟動(dòng)類添加注解
@EnableEurekaServer @EnableWebSecurity
下線服務(wù)
http://eureka地址:端口/eureka/apps/服務(wù)名/服務(wù)地址:服務(wù)端口號(hào)
實(shí)例如下：
erueka注冊(cè)中心ip: 10.100.1.100
端口: 12000
服務(wù)名: CPS-RISK-SERVER
實(shí)例id: 192.168.10.54:18883
則向下面的url通過http發(fā)送delete命令，可將指定的服務(wù)實(shí)例刪除：
http://10.100.1.100:12000/eureka/apps/CPS-RISK-SERVER/192.168.10.54:18883
變更服務(wù)狀態(tài)
http://eureka地址:端口/eureka/apps/服務(wù)名/服務(wù)地址/status?value=${value}
其中${value}的取值為：OUT_OF_SERVICE , DOWN , UP
