准备工作

以各大云主机厂商常用的镜像centos-8.5为例.

# cat /etc/redhat-release 
CentOS Linux release 8.5.2111

# ip addr

       valid_lft 603011sec preferred_lft 603011sec

测试期间,建议先关闭SELINUX和firewall

setenforce 0
sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config
systemctl disable firewalld
systemctl stop firewalld

创建软链接

ln -s /usr/local/bind/sbin/rndc   /usr/sbin/rndc
ln -s /usr/local/bind/sbin/named  /usr/bin/named
ln -s /usr/local/bind/sbin/named-checkconf  /usr/bin/named-checkconf
ln -s /usr/local/bind/bin/dig /usr/bin/dig
ln -s /usr/local/bind/bin/nslookup /usr/bin/nslookup
ln -s /usr/local/bind/bin/host /usr/bin/host

配置

创建配置目录及bind9启动用户bind

mkdir -p /usr/local/bind/{etc,var}
useradd -s /sbin/nologin -d /usr/local/bind/var/named bind
mkdir -p /usr/local/bind/var/named/{logs,dynamic,slaves,run}
chown bind:bind -R /usr/local/bind/var/named

rndc配置

/usr/local/bind/sbin/rndc-confgen > /usr/local/bind/etc/rndc.conf
tail -10 /usr/local/bind/etc/rndc.conf | head -9 | sed s/#\ //g > /usr/local/bind/etc/rndc.key

named.ca文件

named.ca是根域的ns记录。

/usr/local/bind/bin/dig @a.root-servers.net . -t ns > /usr/local/bind/etc/named.ca

从上面测试来看，bind9源码安装是正常的。

bind webadmin

在配置bind的zone时，bind9支持从文本文件中直接读取，也支持从数据库(如常见的mysql)中读取。不管是哪一种方式，配置bind9的zone都一样麻烦一点点，最近推出一款bind webadmin免费软件，可以很好的解决这一问题，感兴的同学可以体现一下。
