Systemd不激活服務？

Question

我需要在 systemd 上運行一個服務，因為它沒有激活？ 由於我遵循文檔的建議而發生這種情況的原因，以下是代碼：

服務代碼：

# Contents of /etc/systemd/system/quark.service
[Unit]
Description=Quark
After=network.target

[Service]
Type=simple
User=cto
ExecStart=/usr/local/bin/python3.9 /var/net/
Restart=always

[Install]
WantedBy=multi-user.target

狀態代碼：

● quark.service - Quark
   Loaded: loaded (/etc/systemd/system/quark.service; enabled; vendor preset: en
   Active: failed (Result: exit-code) since Mon 2021-06-21 15:20:34 UTC; 8s ago

ExecStart應該是要執行的命令：

系統手冊頁：

ExecStart=

Commands with their arguments that are executed when this service is started.

本節：

ExecStart=/usr/local/bin/python3.9 /var/net/

應該：

ExecStart=/usr/local/bin/python3.9 path_to_python_script.py
