systemd：将 start/stop 传递给服务

Question

我正在尝试创建一个用于启动和停止 softether VPN 服务器的 systemd 初始化脚本。

一个 tutorial 我发现建议遵循 init.d 脚本。

#!/bin/sh
# chkconfig: 2345 99 01
# description: SoftEther VPN Server

DAEMON=/usr/local/vpnserver/vpnserver
LOCK=/var/lock/subsys/vpnserver
test -x $DAEMON || exit 0

case "" in
    start)
        $DAEMON start
        touch $LOCK
        ;;
    stop)
        $DAEMON stop
        rm $LOCK
        ;;
    restart)
        $DAEMON stop
        sleep 3
        $DAEMON start
        ;;
    *)
        echo "Usage: [=11=] {start|stop|restart}"
        exit 1
esac

exit 0

但是我想用systemd，所以我写了下面的服务文件。

[Unit]
Description=Softether VPN server
After=syslog.target
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/vpnserver/vpnserver start
ExecStop=/usr/local/vpnserver/vpnserver stop

# Give a reasonable amount of time for the server to start up/shut down
TimeoutSec=300

[Install]
WantedBy=multi-user.target

但是这个脚本没有保留 VPN 服务器运行。 sudo systemctl status softethervpn 给我以下状态。

● softethervpn.service - Softether VPN server
   Loaded: loaded (/lib/systemd/system/softethervpn.service; disabled)
   Active: deactivating (stop) since Mon 2016-04-18 19:11:41 CEST; 1s ago
  Process: 1463 ExecStart=/usr/local/vpnserver/vpnserver start (code=exited, status=0/SUCCESS)
 Main PID: 1463 (code=exited, status=0/SUCCESS);         : 1474 (vpnserver)
   CGroup: /system.slice/softethervpn.service
           ├─1471 /usr/local/vpnserver/vpnserver execsvc
           └─control
             └─1474 /usr/local/vpnserver/vpnserver stop

Apr 18 19:11:40 raspberrypi systemd[1]: Started Softether VPN server.
Apr 18 19:11:41 raspberrypi vpnserver[1463]: The SoftEther VPN Server service has been started.
Apr 18 19:11:42 raspberrypi vpnserver[1474]: Stopping the SoftEther VPN Server service ...
Apr 18 19:11:42 raspberrypi vpnserver[1474]: SoftEther VPN Server service has been stopped.

我需要如何更正我的服务文件才能正常工作？

看来 Type 需要 forking。以下脚本对我有用（在 SoftEther Configurationfile for Systemd 找到）。

[Unit]
Description=SoftEther VPN Server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/vpnserver/vpnserver start
ExecStop=/usr/local/vpnserver/vpnserver stop

[Install]
WantedBy=multi-user.target

systemd：将 start/stop 传递给服务

systemd: Pass start/stop to service

debian

init.d

raspberry-pi

systemd
