eureka.client.service-url.defaultZone 與 eureka.instance.hostsname eureka1、eureka2、eureka3 都再本機的 hosts 文件里事先寫好,
例如 eureka1 服務器上的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
啟動類同樣是添加 @EnableEurekaServer 注意：如果運行 jar 包時需要程序接收命令行參數，一定要再main方法的 SpringApplication.run() 方法 中傳入 args 參數
例如：
|
1
2
3
|
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 --參數名=參數值 參數將不起作用從而影響你無法選擇寫好的環境配置
客戶端：
依賴跟單機的一樣

啟動類注解與單機版一樣
客戶端注冊一臺注冊中心，同時注冊到其他集群中說明成功！
eureka添加 spring-security 權限認證

下線服務
http://eureka地址:端口/eureka/apps/服務名/服務地址:服務端口號
實例如下：
erueka注冊中心ip: 10.100.1.100
端口: 12000
服務名: CPS-RISK-SERVER
實例id: 192.168.10.54:18883
則向下面的url通過http發送delete命令，可將指定的服務實例刪除：
http://10.100.1.100:12000/eureka/apps/CPS-RISK-SERVER/192.168.10.54:18883
變更服務狀態
http://eureka地址:端口/eureka/apps/服務名/服務地址/status?value=${value}
其中${value}的取值為：OUT_OF_SERVICE , DOWN , UP
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持服務器之家。
