yum install -y bind bind-chroot bind-utils
chroot是通过相关文件封装在一个伪根目录内，已达到安全防护的目的，一旦程序被攻破，将只能访问伪根目录内的内容，而不是真实的根目录
BIND安装好之后不会有预制的配置文件，但是在BIND的文档文件夹内（/usr/share/doc/bind-9.9.4），BIND为我们提供了配置文件模板，我们可以直接拷贝过来：
cp -r /usr/share/doc/bind-9.9.4/sample/etc/* /var/named/chroot/etc/ cp -r /usr/share/doc/bind-9.9.4/sample/var/* /var/named/chroot/var/
配置BIND服务的主配置文件（/var/named/chroot/etc/named.conf），命令：vim /var/named/chroot/etc/named.conf；
内容很多使用简单配置，删除文件中logging以下的全部内容，以及option中的部分内容，得到如下配置
vim /var/named/chroot/etc/named.conf
options
{
// Put files that named is allowed to write in the data/ directory:
directory "/var/named"; // "Working" directory
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
};
在主配置文件（/var/named/chroot/etc/named.conf ）中加入，zone参数
vim /var/named/chroot/etc/named.conf
options
{
// Put files that named is allowed to write in the data/ directory:
directory "/var/named"; // "Working" directory
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
};
zone "yaohjk.com" {
type master;
file "yaohjk.com.zone";
};
新建yaohjk.com.zone文件，yaohjk.com的域名解析文件，zone文件放在/var/named/chroot/var/named/下，zone文件可以已/var/named/chroot/var/named/named.localhost为模板。
命令：
cp /var/named/chroot/var/named/named.localhost /var/named/chroot/var/named/yaohjk.com.zone
文件yaohjk.com.zone的内容如下：
[[email protected]]# cat yaohjk.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1

login IN A 192.168.0.199
pay IN A 192.168.0.199
wx IN A 192.168.0.199
禁用bind默认方式启动，改用bind-chroot方式启动。命令如下：
[[email protected] named]# /usr/libexec/setup-named-chroot.sh /var/named/chroot on [[email protected] named]# systemctl stop named [[email protected] named]# systemctl disable named [[email protected] named]# systemctl start named-chroot [[email protected] named]# systemctl enable named-chroot [[email protected] named]# [[email protected] named]# ps -ef|grep named named 25984 1 0 13:41 ? 00:00:00 /usr/sbin/named -u named -c /etc/named.conf -t /var/named/chroot root 29267 48688 0 13:54 pts/1 00:00:00 grep --color=auto named [[email protected] named]#
