我四处寻找，并竭尽全力找出为什么 systemctl 无法启动我的单元。
\n\n我正在尝试将 GCP 的 cloud-sql-proxy 作为 systemd 服务启动。这就是我的cloud-sql-proxy.service样子。
[Install]\nWantedBy=multi-user.target\n\n[Unit]\nDescription=Cloud SQL Proxy\nRequires=networking.service\nAfter=networking.service\n\n[Service]\nType=simple\nWorkingDirectory=/opt\nExecStart=/opt/cloud_sql_proxy -instances=pupa=tcp:5432 -credential_file=/etc/pupa-240309-5336639b0c06.json\nRestart=always\nStandardOutput=journal\nUser=root\n我跑sudo systemctl enable cloud-sql-proxy成功了。然后当我执行时sudo systemctl start cloud-sql-proxy.service失败并显示以下消息：
Failed to start cloud-sql-proxy.service: Unit not found.\n以下是更多信息：
