Centos7 systemctl启动单元未找到

Question

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。

\n\n

[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

\n\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：

\n\n

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

\n\n

以下是更多信息：

对我错过的地方有什么建议吗？\n谢谢！

Requires根据我的经验，这是由于找不到其中一项服务造成的。如果您能够启用服务但启动服务返回，Unit not found请检查 下的服务Requires。就我而言，我有一个Requires: rpcbind.service但该服务未安装在我的系统上。
