Centos7 systemctl start unit not found

我到處尋找，只是為了我的生命找出為什麼 systemctl 不會啟動我的單元。

我正在嘗試將 GCP 的 cloud-sql-proxy 作為 systemd 服務啟動。這就是我的cloud-sql-proxy.service樣子。

[Install]
WantedBy=multi-user.target

[Unit]
Description=Cloud SQL Proxy
Requires=networking.service
After=networking.service

[Service]
Type=simple
WorkingDirectory=/opt
ExecStart=/opt/cloud_sql_proxy -instances=pupa=tcp:5432 -credential_file=/etc/pupa-240309-5336639b0c06.json
Restart=always
StandardOutput=journal
User=root

我sudo systemctl enable cloud-sql-proxy成功地跑了。然後當我執行sudo systemctl start cloud-sql-proxy.service它時失敗並顯示以下消息：

Failed to start cloud-sql-proxy.service: Unit not found.

以下是更多資訊：

$ ll -al /etc/systemd/system/cloud-sql-proxy.service
-rw-r--r--. 1 root root 327 May 22 10:56 /etc/systemd/system/cloud-sql-proxy.service

$ sudo systemctl list-unit-files
...
cloud-sql-proxy.service                       enabled
...

$ systemctl status cloud-sql-proxy

關於我錯過的地方有什麼建議嗎？謝謝！

你能在 /usr/lib/systemd/system/cloud_sql_proxy.service 中嘗試這樣的事情嗎

[Unit]
Description=GCP CloudSQL Proxy
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/usr/bin
Type=forking
RemainAfterExit=yes
ExecStart=/bin/sh -c '/usr/bin/nohup /usr/local/cloud_sql_proxy -instances=${INSTANCE_CONNECTION_NAME} -credential_file=${CREDENTIAL_FILE} &'
StandardOutput=journal
KillMode=process

[Install]
WantedBy=multi-user.target

您的配置文件將是 /usr/lib/systemd/system/cloud_sql_proxy.service.d/settings.conf

[Service]
Environment=INSTANCE_CONNECTION_NAME=[YOUR CONNECTION NAME]
Environment=CREDENTIAL_FILE=[PATH TO YOUR CREDENTIAL FILE]
