springboot启动后总是自己shutdown

由 余生长醉 提交于 2019-12-09 10:25:05
现象 这几天一直被一个问题困扰，每次springboot的tomcat启动之后， 然后过了一段时间看， 进程就突然自己关闭掉了。 然后日志是： ationConfigEmbeddedWebApplicationContext : Closing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@6d5380c2: startup date [Sun Sep 24 17:51:04 CST 2017]; root of context hierarchy o.s.j.e.a.AnnotationMBeanExporter : Unregistering JMX-exposed beans on shutdown j.LocalContainerEntityManagerFactoryBean : Closing JPA EntityManagerFactory for persistence unit 'default' 解法 网上也有说这个问题， 但是大多数说的是， 这个是一个非 web应用， 需要添加这个依赖， 链接 <dependency> <groupId>org.springframework.boot</groupId> <artifactId

Shell_exec php with nohup

由 别说谁变了你拦得住时间么 提交于 2019-12-09 02:59:27
问题 I think there are tons of similar posts but I haven't yet found a solution after searching around. Basically, I'm trying to run two scripts in the background. When I run them in the commandline, I see after calling my first script: /usr/bin/nohup php script.php > nohupoutput.log & echo $! I've tried ...script.php > /dev/null & with the same result. I get: /usr/bin/nohup: ignoring input and redirecting stderr to stdout which I ignore and run the second one. I noticed that it seemed to be

由 假装没事ソ 提交于 2019-12-08 23:55:34
这两年微服务很流行，这里简单介绍一下如何将自己使用idea写的微服务打包成一个可执行的jar包，并发布到linux服务器的步骤。因为spring boot有内置的tomcat所以一般使用内置的tomcat就可以可,当然也使用外部的tomcat容器。 如有疑问可以添加qq:850534486交流 步骤1: File->Project Structure 步骤2: Project Settings->Artifacts->JAR->From modules with dependencies 步骤3: 选择启动类->OK 步骤4: copy to the output directory and link via manifest->OK 步骤5: Apply->OK 步骤6: Build->Build Artifacts 步骤7: demo01.jar->Build 步骤8: 自己写的项目成功生成一个可执行的jar包 步骤9: 将该文件夹复制到对应的服务器上 步骤10: <1>首次部署当前程序需要在对应的文件夹中执行以下命令 a.启动程序 nohup java -jar demo01.jar & b.退出 ctrl + c c.查看日志 tail -500f nohup.out <2>非首次部署当前程序需要在对应的文件夹中执行以下命令 a.捕获上一个版本程序的进程 ps - ef

enter pdb with kill signal

由 泄露秘密 提交于 2019-12-08 02:47:25
问题 In a recent project, I want to debug my program in production use state. The production environment is very complicated so I want to debug the program whenever I find a problem. This is what I want to achieve: whenever I want to debug, I will send a kill signal to the program and hopefully pdb debugger will appear. It is something like this: import pdb import signal import time def handler(signal, frame): pdb.set_trace() signal.signal(signal.SIGTERM, handler) a=1 while True: a+=1 time.sleep(1

How do I write a watchdog daemon in bash?

由 天大地大妈咪最大 提交于 2019-12-08 02:27:06
问题 I want a way to write a daemon in a shell script, which runs another application in a loop, restarting it if it dies. When run using ./myscript.sh from an SSH session, it shall launch a new instance of the daemon, except if the daemon is already running. When the SSH session ends, the daemon shall persist. There shall be a parameter ( ./myscript -stop ) that kills any existing daemon. ( Notes on edit - The original question specified that nohup and similar tools may not be used. This

由 不羁岁月 提交于 2019-12-07 20:02:03
问题 I built a web service using tornado and it serves days and nights. I used the command to start my service: nohup python my_service.py & The service log is able to write to nohup.out .

Such as: service_log_1.txt service_log_2.txt service_log_3.txt ... Thanks. 回答1: Yes, there is. Put a cron-job in effect,

Possible I/O sync issue with Ruby script under nohup?

由 假如想象 提交于 2019-12-07 19:01:04
问题 This question was migrated from Super User because it can be answered on Stack Overflow. Migrated 6 years ago . Had an odd issue with the output of a Ruby script running under nohup. Basically, there's a severe output delay when writing to a logfile or with stdout to nohup.out. You can see the original post here, which was answered for that use case: StackOverflow - Question 19455667 It was suggested that I use something like file_object.sync = true Which works, however I'm interested in the

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . What is performed behind the scenes when a program runs with nohup? Is the PID of the parent process being changed? Thanks. EDIT : I understood that nohup (and disown) causes that SIGHUP is not sent to the process if the parent process receives it. Does it mean that it is equivalent to handling SIGHUP (and
