Question

我想在CentOS 7启动中运行交互式 Shell脚本，我曾经尝试过post install，/etc/rc.local和crontab @reboot，但没有一个与我合作

此外，我已经将它作为systemd进行了尝试，但也失败了。除了将其添加到登录之外，我需要任何方式来运行此脚本，我希望它在用户登录系统之前运行。有什么建议吗？

hostname=""
ip=""
netmask=""
gw=""
opts=""
answer="n"
device="eth0"
hwaddr=`ifconfig $device | grep -i hwaddr | sed -e 's#^.*hwaddr[[:space:]]*##I'`
dns1="205.171.2.65"
dns2="205.171.3.65"

curTTY=`/dev/tty`
exec < $curTTY > $curTTY 2> $curTTY
clear

while [ x"$answer" != "xy" ] && [ x"$answer" != "xY" ] ; do
        echo -n "enter hostname: "; read hostname
        echo -n "enter ip: "; read ip
        echo -n "enter netmask: "; read netmask
        echo -n "enter default gw: "; read gw
        echo -n "hard set '100baseTX full-dulplex' [y/n] " ; read opts
        echo

        echo You entered:
        echo -e "\thostname: $hostname"
        echo -e "\tip: $ip"
        echo -e "\tnetmask: $netmask"
        echo -e "\tdefault gw: $gw"
        echo -e "\tset 100baseTX full-duplex: $opts"
        echo -n "Is this correct? [y/n] "; read answer
done

if [ x"$opts" = "xy" ] ; then
        opts="speed 100 duplex full autoneg off"
else
        opts=""
fi

sed -i -e 's#^\(HOSTNAME=\).*$#\1'"$hostname"'#' /etc/sysconfig/network
echo GATEWAY=$gw >> /etc/sysconfig/network

echo DEVICE=$device > $scrFile
echo BOOTPROTO=static >> $scrFile
echo ONBOOT=yes >> $scrFile
echo NM_CONTROLLED=no >> $scrFile
echo HWADDR=$hwaddr >> $scrFile
echo IPADDR=$ip >> $scrFile
echo NETMASK=$netmask >> $scrFile
echo USERCTL=no >> $scrFile
echo DNS1=$dns1 >> $scrFile
echo DNS2=$dns2 >> $scrFile

if [ "x$opts" != "x" ] ; then
        echo 'ETHTOOL_OPTS="'"$opts"'"' >> $scrFile
fi
