如果用nohup啟動jar包的話，默認的日志文件就是nohup.out，那么如果啟動多個jar包的話，看日志文件就麻煩了，因為他們都會寫入到nohup.out文件中。
所以我們來指定一下不同jar包的日志文件名：
[prize@centos ~]$ mkdir log [prize@centos ~]$ nohup java -jar dianyixia-0.0.1-SNAPSHOT.jar > log/dianyixia.log & [1] 5861 [prize@centos ~]$ nohup: ignoring input and redirecting stderr to stdout
看一眼，日志確實寫入到dianyixia.log文件中了：
[prize@centos ~]$ cat log/dianyixia.log . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.2.2.RELEASE) 2019-12-23 11:37:19.899 INFO 5861 --- [ main] c.w.o.dianyixia.DianyixiaApplication : Starting DianyixiaApplication v0.0.1-SNAPSHOT on VM_0_14_centos with PID 5861 (/home/prize/dianyixia-0.0.1-SNAPSHOT.jar started by prize in /home/prize) 2019-12-23 11:37:19.905 INFO 5861 --- [ main] c.w.o.dianyixia.DianyixiaApplication : No active profile set, falling back to default profiles: default 2019-12-23 11:37:22.500 INFO 5861 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 9998 (http) 2019-12-23 11:37:22.531 INFO 5861 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat] 2019-12-23 11:37:22.531 INFO 5861 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet engine: [Apache Tomcat/9.0.29] 2019-12-23 11:37:22.711 INFO 5861 --- [ main] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext 2019-12-23 11:37:22.711 INFO 5861 --- [ main] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 2672 ms 2019-12-23 11:37:24.099 INFO 5861 --- [ main] o.s.s.concurrent.ThreadPoolTaskExecutor : Initializing ExecutorService 'applicationTaskExecutor' 2019-12-23 11:37:24.552 INFO 5861 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 9998 (http) with context path '' 2019-12-23 11:37:24.555 INFO 5861 --- [ main] c.w.o.dianyixia.DianyixiaApplication : Started DianyixiaApplication in 5.653 seconds (JVM running for 6.653)
如法炮制，再來一個：
[prize@centos ~]$ nohup java -jar prize-0.0.1-SNAPSHOT.jar > log/prize.log & [2] 6306 [prize@centos ~]$ nohup: ignoring input and redirecting stderr to stdout
看看
