CentOS7安装bind域名服务

安装Bind Chroot DNS 服务器

yum install bind-chroot bind -y

拷贝bind相关文件,准备bind chroot 环境

cp -R /usr/share/doc/bind-*/sample/var/named/* /var/named/chroot/var/named/

在bind chroot 的目录中创建相关文件

touch /var/named/chroot/var/named/data/cache_dump.db
touch /var/named/chroot/var/named/data/named_stats.txt
touch /var/named/chroot/var/named/data/named_mem_stats.txt
touch /var/named/chroot/var/named/data/named.run
mkdir /var/named/chroot/var/named/dynamic
touch /var/named/chroot/var/named/dynamic/managed-keys.bind

将 Bind 锁定文件设置为可写

chmod -R  /var/named/chroot/var/named/data
chmod -R  /var/named/chroot/var/named/dynamic

将/etc/named.conf 拷贝到 bind chroot目录

# cp -p /etc/named.conf /var/named/chroot/etc/named.conf

# vi /var/named/chroot/etc/named.conf

options {
    listen-on port  { xxxxxxxxxx; };
    listen-on-v6 port  { ::; };
    directory   "/var/named";
    dump-file   "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";
    allow-query     { any; };
        //forwarders { 114.114.114.114; };

..
..
zone "example.local" {
    type master;
    file "example.local.zone";
};

zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.0.zone";
};
..
..

为 example.local 域名创建转发域与反向域文件

 # vi /var/named/chroot/var/named/example.local.zone

 ;
 ;       Addresses and other host information.
 ;
 $TTL
 @       IN      SOA     example.local. hostmaster.example.local. (
                                      ; Serial
                                      ; Refresh
                                       ; Retry
                                    ; Expire
                                 )  ; Minimum

 ;       Define the nameservers and the mail servers

                IN      NS      ns1.example.local.
                IN      NS      ns2.example.local.
                IN      A       192.168.0.70
                IN      MX       mx.example.local.

 centos7          IN      A       192.168.0.70
 mx               IN      A       192.168.0.50
 ns1              IN      A       192.168.0.70
 ns2              IN      A       192.168.0.80

创建转发域

 # vi /var/named/chroot/var/named/192.168..zone

 ;
 ;       Addresses and other host information.
 ;
 $TTL
 @       IN      SOA     example.local. hostmaster.example.local. (
                                      ; Serial
                                      ; Refresh
                                       ; Retry
                                    ; Expire
                                 )  ; Minimum

 0.168..in-addr.arpa. IN      NS      centos7.example.local.

 70.0.168.192.in-addr.arpa. IN PTR mx.example.local.
 70.0.168.192.in-addr.arpa. IN PTR ns1.example.local.
 80.0.168.192.in-addr.arpa. IN PTR ns2.example.local.

创建方向域

开机自启动 bind-chroot 服务

/usr/libexec/setup-named-chroot.sh /var/named/chroot on
systemctl stop named
systemctl disable named
systemctl start named-chroot
systemctl enable named-chroot
ln -s '/usr/lib/systemd/system/named-chroot.service' '/etc/systemd/system/multi-user.target.wants/named-chroot.service'
