如何设置systemd服务以30秒为周期重试5次 [英] How to set up a systemd service to retry 5 times on a cycle of 30 seconds

问题描述

我希望 systemd 启动脚本并重试最多 5 次，间隔 30 秒.阅读 systemd.service 手册并在互联网上搜索并没有得到任何明显的答案.

I want systemd to start a script and retry a maximum of 5 times, 30s apart. Reading the systemd.service manual and searching the Internet didn't produce any obvious answers.

要允许最多 5 次重试间隔 30 秒，请使用相关 systemd 服务文件中的以下选项.

To allow a maximum of 5 retries separated by 30 seconds use the following options in the relevant systemd service file.

[Unit]
StartLimitInterval=200
StartLimitBurst=5
[Service]
Restart=always
RestartSec=30

对于使用Type=idle"运行脚本的服务，这对我有用.请注意，'StartLimitInterval' 必须大于 'RestartSec * StartLimitBurst'，否则服务将无限期重启.

This worked for me for a service that runs a script using 'Type=idle'. Note that 'StartLimitInterval' must be greater than 'RestartSec * StartLimitBurst' otherwise the service will be restarted indefinitely.
