Question

我想将我的Java应用程序作为Linux服务启动。我创建了一个包装文件：

SERVICE_NAME=ConfigurationService PATH_TO_JAR=/opt/Applications/Configuration-Service/configuration-service.jar PID_PATH_NAME=/tmp/ConfigurationService-pid case $1 in
start)
    echo "Starting $SERVICE_NAME ..."
    if [ ! -f $PID_PATH_NAME ]; then
        nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                    echo $! > $PID_PATH_NAME
        echo "$SERVICE_NAME started ..."
    else
        echo "$SERVICE_NAME is already running ..."
    fi
;;
stop)
    if [ -f $PID_PATH_NAME ]; then
        PID=$(cat $PID_PATH_NAME);
        echo "$SERVICE_NAME stoping ..."
        kill $PID;
        echo "$SERVICE_NAME stopped ..."
        rm $PID_PATH_NAME
    else
        echo "$SERVICE_NAME is not running ..."
    fi
;;
restart)
    if [ -f $PID_PATH_NAME ]; then
        PID=$(cat $PID_PATH_NAME);
        echo "$SERVICE_NAME stopping ...";
        kill $PID;
        echo "$SERVICE_NAME stopped ...";
        rm $PID_PATH_NAME
        echo "$SERVICE_NAME starting ..."
        nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                    echo $! > $PID_PATH_NAME
        echo "$SERVICE_NAME started ..."
    else
        echo "$SERVICE_NAME is not running ..."
    fi
;; esac

但是，当我用命令启动它时：

service ConfigurationService start

应用程序启动但无权连接到DataBase。当我调用我的Web API时，我可以看到这样的错误：

出现意外错误（type = Internal Server Error，status = 500）。无法获得JDBC连接;嵌套异常是java.sql.SQLException：用户'root'@'localhost'拒绝访问（使用密码：YES）

如果我使用命令启动我的应用程序，它可以正常工作：

java -jar ConfigurationService.jar &

我知道它与用户和权限相关，但我是Linux配置的新手。感谢任何帮助
