OpenVPN启动后如何让Systemd运行脚本？

  • 772

一般来说，我正在尝试使用服务执行脚本。所以它由于某种原因不起作用：

[Unit]
Description=Description
After=network.target
After=openvpn.service

[Service]
ExecStart=/path_to_dir/script.sh --flag param
Type=simple
RemainAfterExit=false

[Install]
WantedBy=multi-user.target

这是他写的：

tun0: error fetching interface information: Device not found
my_script.service: Succeeded.

内容openvpn.service：

# This service is actually a systemd target,
# but we are using a service since targets cannot be reloaded.

[Unit]
Description=OpenVPN service
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/true
ExecReload=/bin/true
WorkingDirectory=/etc/openvpn

[Install]
WantedBy=multi-user.target

    一般来说，我只是通过在脚本开头添加一个小循环来解决问题：

    while true
do
    ip l | grep tun0 > /dev/null

    if [[ $? -eq 0 ]]
    then
        break
    else
        sleep 1
    fi
done
