Centos7 systemctl 启动单元未找到

Centos7 systemctl 启动单元未找到

我到处寻找，只是想弄清楚为什么 systemctl 无法启动我的设备。

我正在尝试将 GCP 的 cloud-sql-proxy 作为 systemd 服务启动。这就是我的样子cloud-sql-proxy.service。

[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成功运行了。然后当我执行sudo systemctl start cloud-sql-proxy.service它时失败并显示以下消息：

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

以下是更多信息：

$ 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

对我遗漏的地方有什么建议吗？谢谢！

您可以在 /usr/lib/systemd/system/cloud_sql_proxy.service 中尝试类似这样的操作吗？

[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

您的配置文件将是 /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]

答案2

根据我的经验，这是由于Requires未找到其中一项服务。如果您能够启用服务但启动服务时返回，Unit not found则检查 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。

我觉得你正在关注这个[1]链接，但如果你看底部，他们指定如果你想在 Centos 7 上执行相同操作，则需要使用不同的文件。也许这就是它失败的原因。

对于 Centos 7，使用以下命令：

[Install]
WantedBy=multi-user.target

[Unit]
Description=Google Cloud Compute Engine SQL Proxy
Requires=network.target
After=network.target

[Service]
Type=simple
WorkingDirectory=/usr/local/bin
ExecStart=/usr/local/bin/cloud_sql_proxy -dir=/var/run/cloud-sql-proxy -instances=<instance_connection_name>=tcp:3306 -credential_file=/var/local/cloud-sql-proxy/<credential_json>.json
Restart=always
StandardOutput=journal
