下载
首先在158和159主机上下载bind和bind-utils
yum -y install bind-utils bind
如果下载较慢的话使用清华大学的yum源
清华大学源地址
Index of /centos-stream/9-stream/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror
cd /etc/yum.repos.d/
创建bak
mkdir bak
移动
mv -pv * bak/
ls -lhrt
vim base.repo
填入如下内容
[root@localhost yum.repos.d]# cat centos.repo
[baseos]
name=CentOS Stream $releasever - BaseOS
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=BaseOS&infra=$infra
baseurl=https://mirrors.ustc.edu.cn/centos-stream/9-stream/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
[appstream]
name=CentOS Stream $releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=AppStream&infra=$infra

gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
配置完成之后
yum clean all
清除所有缓存
yum makecache
重新生成缓存
查看该命令在哪里
[root@dns-master190 ~]# which named-checkconf
/usr/sbin/named-checkconf
查看该命令来自那个安装包

检测配置是否正确

[root@rsync-158 named]# named-checkzone ldp.com ldp.com.zone

OK
启动
systemctl start named
查看端口
udp的53端口是提供域名解析服务的，tcp的53是提供bind服务的
将网卡文件的DNS 记录注释
之后执行nmcli c reload和nmcil c up ens160
进入配置/etc/resolv.conf文件
[root@rsync-158 named]# cat /etc/resolv.conf
