创建守护进程来运行 .sh

我已经尝试了一段时间，但一直无法创建运行脚本的服务。我尝试运行的脚本如下。

#!/bin/sh
while true

do

sudo bbb-record --rebuildall

sleep 300
done

我尝试创建一个守护进程来运行它，如下所示：

[Unit]
Description=bbb-rebuild
[Service]
ExecStart=/home/sysadmin/rebuild
Restart=always

[Install]
WantedBy=multi-user.target 

exit=0

我收到错误消息

==== AUTHENTICATION COMPLETE ===
Failed to start rebuild.service: Unit rebuild.service is not loaded properly: Invalid argument.

你最好使用systemd-定时器为了达成这个。

创建一个名为“systemd 服务”的计时器rebuild.timer

# nano /etc/systemd/system/rebuild.timer

[Unit]
Description=Start script every hour

[Timer]
OnCalendar=hourly

[Install]
WantedBy=timers.target

编辑脚本如下

#!/bin/sh
bbb-record --rebuildall

确保脚本可运行chmod +x /home/sysadmin/rebuild

编辑你的 systemd 服务以删除restart=always和exit 0

[Unit]
Description=bbb-rebuild

[Service]
ExecStart=/home/sysadmin/rebuild

[Install]
WantedBy=multi-user.target

然后只需使用 启用你的 systemd-timer 即可systemctl enable rebuild.timer。
然后使用 检查计时器是否已启用systemctl status rebuild.timer。
