linux 靜態ip設置shell版本

      參照網上設置linux 靜態ip的教程，爲了練習相應shell腳本，本人特爲之編寫了一個自動化設置靜態ip的腳本，相應設置信息均以shell命令完成，如需改動也可以再在腳本里改動相應內容，具體shell代碼如下：

 

#! /bin/sh -

# the shell used for redhat linux or redhat-based linux os
cat > /etc/sysconfig/network-scripts/ifcfg-eth0 << EOF
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.94.133
NETMASK=255.255.255.0
GATEWAY=192.168.94.1
EOF

if [ $? -ne 0 ]
then
    echo "Error!May don't have the privileges"
    exit 1
fi

/sbin/ifdown eth0
/sbin/ifup eth0

if [ $? -ne 0 ]
then
    echo "Error!May cannot find eth0 or canot drive!"
    exit 2
fi

#強制設置權限取消
chattr -i /etc/resolv.conf
cat > /etc/resolv.conf << EOF
domain localdomain
search localdomain
nameserver 192.168.94.1
nameserver 202.96.134.133
EOF
chattr +i /etc/resolv.conf

/etc/init.d/network restart
