我有一個在 ubuntu 上運行 java 應用程序的腳本nohup java -Xms512m -Xmx8g -jar /data/software/190716/myapp-0.0.1.jar --server.port=8080 --spring.config.location=/data/software/myapp.properties > ~/running.myapp.log &我可以制作一個.sh腳本來使命令啟動、停止和重新啟動進程嗎？謝謝

如評論中所述，更好的方法是遵循running-a-java-process-from-systemd
但是如果你真的對 bash 腳本感興趣，那么你可以做這樣的事情，但請記住，可能有更好的方法。
#!/bin/bash
function 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

? ? 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

}
case "$1" in?
