运行 systemd 服务之前/之后挂载/卸载远程共享

  • 772

我想使用systemd运行一个脚本，通过将数据保存到远程存储来进行备份，因此：

  • 挂载远程存储（例如NFS共享）
  • 运行脚本
  • 卸载远程存储

这就是我试图做的：

cat /etc/systemd/system/mnt-server-share.mount

[Unit]
Description=Remote storage test
After=network.target

[Mount]
What=server:/share
Where=/mnt/server/share
Type=nfs
Options=defaults,noauto
TimeoutSec=30

[Install]
WantedBy=multi-user.target

cat /etc/systemd/system/backuptest.service

[Unit]
Description=Remote backup test
RequiresMountsFor=/mnt/server/share

[Service]
Type=simple
ExecStart=/usr/local/bin/backup.sh
ExecStop= systemctl stop mnt-server-share.mount

[Install]
WantedBy=multi-user.target

但在脚本结束/失败后，远程存储不再是umount。我可以将mount/umount放入脚本中，但我希望我可以使用systemd来完成...任何人都可以帮助我做到这一点吗？

systemd

    在自动挂载文件中/etc/systemd/system/mnt-server-share.mount指定空闲超时值。

    TimeoutIdleSec=

      Configures an idle timeout. Once the mount has been idle for the specified time, systemd will attempt to unmount. Takes a unit-less value in seconds, or a time span value such as "5min 20s". Pass 0 to disable the timeout logic. The timeout is disabled by default.

    从你的例子来看：

    [Unit]
Description=Remote storage test
After=network.target

[Mount]
What=server:/share
Where=/mnt/server/share
Type=nfs
Options=defaults,noauto
TimeoutSec=30
TimeoutIdleSec=1m

[Install]
WantedBy=multi-user.target
