7. init.dスクリプトの作成

# vi /etc/init.d/vpnserver

以下の内容を記載する

#!/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 "$1" in
    start)
        $DAEMON start
        touch $LOCK
        ;;
    stop)
        $DAEMON stop
        rm $LOCK
