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.
