SHELL脚本之配置DNS分离服务

配置DNS分离服务之解析脚本文件

1.实验环境:

准备2个网卡

2.脚本如下:

#!/bin/bash #配置双网卡 #定义网卡配置文件位置 k=/etc/sysconfig/network-scripts #复制网卡配置文件模板 cd /etc/sysconfig/network-scripts cp -p ifcfg-ens33 ifcfg-ens36 #修改第1块网卡配置文件 sed -i 's/dhcp/static/' $k/ifcfg-ens33 cat >>$k/ifcfg-ens33 <<-EOF IPADDR=192.168.100.1 NETMASK=255.255.255.0 EOF #修改第2块网卡配置文件 sed -i 's/dhcp/static/' $k/ifcfg-ens36 sed -i 's/ens33/ens36/' $k/ifcfg-ens36 sed -i '/UUID/d' $k/ifcfg-ens36 cat >>$k/ifcfg-ens36 <<-EOF IPADDR=12.0.0.1 NETMASK=255.255.255.0 EOF #重启网络服务 systemctl restart network #安装dns服务 yum install bind -y #修改主配置文件 sed -i '/listen-on/s/127.0.0.1/any/' /etc/named.conf sed -i '/allow-query/s/localhost/any/' /etc/named.conf sed -i '54,57d' /etc/named.conf #修改区域配置文件 sed -i '12,$d' /etc/named.rfc1912.zones cat >>/etc/named.rfc1912.zones <<-EOF view "lan" { match-clients { 192.168.100.0/24; }; zone "kgc.com."
