Eureka部署linux環境掛載執行

• 首先是pom檔案 對內嵌tomcat的處理javax.servlet-api；
• maven管理依賴的引入spring-boot-maven-plugin；
• springcloud依賴的引入spring-cloud-dependencies；

</project>
 

• 然後是啟動類的改動 SpringBootServletInitializer 支援外部啟動

package 公司名.eureka.eureka;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer
@SpringBootApplication
public class 公司名EurekaApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(HnEurekaApplication.class, args);
    }
}
 

• 然後是配置檔案properties 這裡主要是註冊中心ip地址的配置改動0.0.0.0 這裡不太懂，一直配指定ip ， 這裡聽取了王董的建議

server.port = 7517
spring.application.name = HnEureka

#Eurekalock
#security.basic.enabled = true
#security.user.name = user
#security.user.password = 123456

#EurekaServer
eureka.instance.hostname = eureka
eureka.client.register-with-eureka = false
eureka.client.fetch-registry = false
eureka.client.serviceUrl.defaultZone = http://0.0.0.0:0/eureka/
 

• 然後傳到linux環境下，記得裝匹配版本的jdk ， 這裡用的是1.8
• 然後執行linux 命令試執行專案， java -jar item.jar 如果看到了美麗的springboot啟動成功畫面，那麼恭喜下自己
• 然後讓專案後臺執行，啟用懸掛命令(item.jar=當前的jar全名) nohup java -jar target/item.jar > /dev/null 2>&1 &
• 如果這個時候看到的畫面卡頓了，不用擔心，關閉ssh連結，重新進入一下
• ps -ef |grep eureka 檢視下我們的程序 
• 
• 這個時候訪問一下我們的Eureka 
• 
• 呀！出來了，心情大家懂得啊
