脚本启动与停止的问题

[Fivemeters]

请问下shell脚本中的 ./###.jar start 这种启动方式，我看spring boot启动的时候日志不会打印到控制台，后台在运行，也没有加nohup命令，这个是怎么做到的，是怎么配置的。

To achieve the behavior where a Spring Boot application runs in the background without printing logs to the console, without using nohup, you can modify the startup script that executes the JAR file. Specifically, you can redirect the output to /dev/null and run the process in the background. Here's how you can adjust the script:

./$SERVICE_NAME".jar" start > /dev/null 2>&1 &

This line does the following:

• > /dev/null discards the standard output (stdout).
• 2>&1 redirects the standard error (stderr) to stdout, which is already being discarded.
• & runs the process in the background.

Additionally, within the Apollo repository, you can control logging behavior through configuration. For instance, setting the LOG_APPENDERS environment variable to "FILE" in the apollo-portal.conf file directs the application to log only to a file, not to the console. This setup is part of how Apollo manages its logging and background execution behavior.

you may use vi to edit the ###.jar, and then you will some bash scripts.
