如评论中所述，更好的方法是遵循running-a-java-process-from-systemd但是如果你真的对 bash 脚本感兴趣，那么你可以做这样的事情，但请记住，可能有更好的方法。#!/bin/bashfunction start_app() { # tested with this , uncomment your command nohup node bin/www > logfile.txt 2>&1 & # nohup java -Xms512m -Xmx8g -jar /data/software/190716/myapp-0.0.1.jar --server.port=8080 --spring.config.location=/data/software/myapp.properties # write the pid to text to file to use it later app_pid=$! echo "Process started having PID $app_pid" # wait for process to check proper state, you can change this time accordingly sleep 3 if ps -p $app_pid > /dev/null then echo "Process successfully running having PID $app_pid" # write if success echo $app_pid > process_id.txt else echo "Process stopped before reached to steady state" fi}function stop_app() { # Get the PID from text file application_pid=$(cat process_id.txt) echo "stopping process, Details:" # print details ps -p $application_pid # check if running if ps -p $application_pid > /dev/null then # if running then kill else print message echo "Going to stop process having PId $application_pid" kill -9 $application_pid if [ $? -eq 0 ]; then echo "Process stopped successfully" else echo "Failed to stop process having PID $application_pid" fi else echo "Failed to stop process, Process is not running" fi}case "$1" in start_app) start_app ;; stop_app) stop_app ;; restart) stop_app; start_app ;; *) echo "usage: $0 start_app|stop_app|restart_app" >&2 exit 1 ;;esac
