systemd作业失败没有这样的文件或目录

Question

一直试图按照此脚本启动气流

https://linuxconfig.org/how-to-automatically-execute-shell-script-at-startup-boot-on-systemd-linux

所以我在/usr/local/bin/airflow-start-all.sh中有以下sh文件

#!/bin/bash
echo "starting up postgres service"
export AIRFLOW_HOME=~/airflow
sudo service postgresql start
echo "sleeping"
sleep 15
echo "initiating database"
airflow initdb
echo "sleeping"
sleep 15
gnome-terminal -e /home/ubuntu/Source/Bash/airflow-start-webserver.sh
sleep 15
echo "starting rabbitmq service"
sudo service rabbitmq-server start
sleep 15
gnome-terminal -e /home/ubuntu/Source/Bash/airflow-start-scheduler.sh
sleep 15
gnome-terminal -e /home/ubuntu/Source/Bash/airflow-start-worker.sh

和/etc/systemd/system/airflow-start-service.service中的以下文件

[Unit]
Description=My last command
After=default.target

[Service]
ExecStart=/usr/local/bin/airflow-start-all.sh

[Install]
WantedBy=default.target

我跑了

sudo chmod 744 /usr/local/bin/airflow-start-all.sh

和

sudo chmod 664 /etc/systemd/system/airflow-service-start.service

以及

systemctl daemon-reload
systemctl enable disk-space-check.service

它似乎并没有在启动时启动服务 - 我得到的只是：

知道我哪里出错了？

谢谢， 添
