[root@localhost ~]# cat network.sh
#!/bin/bash
#调整eth0文件
sed -i "/^IPV6/d" /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i "s/dhcp/static/g" /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i "s/ONBOOT=no/ONBOOT=yes/g" /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i "s/UUID/#UUID/g" /etc/sysconfig/network-scripts/ifcfg-eth0
#IP地址：
ifconfig -a | grep broadcast | awk -F‘ ‘ ‘{print "IPADDR="$2}‘ >> /etc/sysconfig/network-scripts/ifcfg-eth0
#子网掩码：
ifconfig -a | grep broadcast | awk -F‘ ‘ ‘{print "NETMASK="$4}‘ >> /etc/sysconfig/network-scripts/ifcfg-eth0
#网关：
cat /etc/resolv.conf | grep nameserver | awk -F‘ ‘ ‘{print "GATEWAY="$2}‘ >> /etc/sysconfig/network-scripts/ifcfg-eth0
#DNS：
cat /etc/resolv.conf | grep nameserver | awk -F‘ ‘ ‘{print "DNS1="$2}‘ >> /etc/sysconfig/network-scripts/ifcfg-eth0
#重启网络：
systemctl restart network
