基础依赖
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.cloud:spring-cloud-starter')eureka（单机）
服务端：
依赖
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')application.yml 配置
spring: application: name: dev eureka: client: service-url: defaultZone: http://本机ip地址:8761/eureka/ #注册中心地址 register-with-eureka: false #表明该实例是否应该与尤里卡服务器登记其信息被别人发现。在某些情况下,您不希望您的实例被发现而你想发现其他实例。默认为true fetch-registry: false #表明这个客户是否应该从尤里卡服务器获取尤里卡注册表信息。默认为true server: port: 8761
启动类添加 @EnableEurekaServer
客户端：
主要依赖
compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')application.yml 配置
eureka: client: service-url: defaultZone: http://eureka服务地址:8761/eureka/
启动类添加 @EnableDiscoveryClient （注册中心通用客户端注解）或 @EnableEurekaClient （只有eureka客户端可用）
eureka（集群）
服务端
主要依赖
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 #使用自我保护，默认true peer-node-read-timeout-ms: 5000 #节点读取超时时间，默认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 与 eureka.instance.hostsname eureka1、eureka2、eureka3 都再本机的 hosts 文件里事先写好,
例如 eureka1 服务器上的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
启动类同样是添加 @EnableEurekaServer 注意：如果运行 jar 包时需要程序接收命令行参数，一定要再main方法的 SpringApplication.run() 方法 中传入 args 参数
例如：
public static void main(String[] args) {
SpringApplication.run(QnbbsConsumer.class,args);
}如果不传入的话在命令行输入 java -jar xxx.jar --参数名=参数值 参数将不起作用从而影响你无法选择写好的环境配置
客户端：
依赖跟单机的一样
application.yml 配置
eureka: instance: prefer-ip-address: true #是否显示ip ip-address: 本机ip #填写本机ip地址 client: service-url: defaultZone: http://eureka1:8761/eureka/,http://eureka2:8761/eureka/，http://eureka3:8761/eureka/
启动类注解与单机版一样
客户端注册一台注册中心，同时注册到其他集群中说明成功！
eureka添加 spring-security 权限认证
依赖
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
server:
port: 8761
spring:
application:
name: eureka-server
security:
user:
name: zyn
password: zyn123...
#用户名与密码若是不配置，系统会自动生成并打印在控制台日志上
eureka:
client:
register-with-eureka: false
fetch-registry: false
server:
enable-self-preservation: false
peer-node-read-timeout-ms: 5000

spring:

instance:
hostname: eureka-C创建一个类并继承 WebSecurityConfigurerAdapter 类，并在此类上添加 @EnableWebSecurity和@Configuration 注解，重写 configure 方法
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(); // 关闭csrf
http.authorizeRequests().anyRequest().authenticated().and().httpBasic(); // 开启认证
}
}启动类添加注解
@EnableEurekaServer @EnableWebSecurity
下线服务
http://eureka地址:端口/eureka/apps/服务名/服务地址:服务端口号
实例如下：
erueka注册中心ip: 10.100.1.100
端口: 12000
服务名: CPS-RISK-SERVER
实例id: 192.168.10.54:18883
则向下面的url通过http发送delete命令，可将指定的服务实例删除：
http://10.100.1.100:12000/eureka/apps/CPS-RISK-SERVER/192.168.10.54:18883
变更服务状态
http://eureka地址:端口/eureka/apps/服务名/服务地址/status?value=${value}
其中${value}的取值为：OUT_OF_SERVICE , DOWN , UP
