刷新服务

cd /free_cicdfs0/compose/bind9
docker-compose down; docker-compose up -d

修改配置文件

新版本 配置文件 大致结构发生了一些改变

cat /free_cicdfs0/data/bind9/etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include \”/etc/bind/named.conf.options\”;
include \”/etc/bind/named.conf.local\”;
include \”/etc/bind/named.conf.default-zones\”;

从 114 缓存 查询 数据

cat > /free_cicdfs0/data/bind9/etc/bind/named.conf.options <<\”EOF\”

# include \”/etc/rndc.key\”;

controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { \”rndckey\”; };
};

options {

// set no
dnssec-enable no;
dnssec-validation no;

listen-on port 53 { any; };

allow-query { any; };

forwarders {
114.114.114.114;
};
};

EOF

chmod 777 -R /free_cicdfs0/data/bind9/
chown root:root -R /free_cicdfs0/data/bind9/

chown root:named -R /free_cicdfs0/data/bind9/

docker-compose up -d
# log error
couldn\’t add command channel 127.0.0.1#953: file not found
docker cp -a bind9:/etc/bind /free_cicdfs0/data/bind9/etc/

docker cp -a bind9:/var/lib/bind /free_cicdfs0/data/bind9/var/lib/

可以 dig 无法 ping

broken trust chain resolving \’baidu.com/AAAA/IN\’: 114.114.114.114#53

解决:
由于是局域网内非法DNS,所以将DNS安全关闭.
[root@192-168-174-42 ~]# vim /etc/named.conf
将下面的两项设置为no
dnssec-enable no;
dnssec-validation no;

查看 已经 区域 解析,并添加 新的 解析 项

cat /free_cicdfs0/data/bind9/etc/bind/named.conf.default-zones
// prime the server with knowledge of the root servers
zone \”.\” {
type hint;
file \”/usr/share/dns/root.hints\”;
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone \”localhost\” {
type master;
file \”/etc/bind/db.local\”;
};

zone \”127.in-addr.arpa\” {
type master;
file \”/etc/bind/db.127\”;
};

zone \”0.in-addr.arpa\” {
type master;
file \”/etc/bind/db.0\”;
};

zone \”255.in-addr.arpa\” {
type master;
file \”/etc/bind/db.255\”;
};

192.168.164.190 nginx164190.zk.wh.com

在 linux 安装 局域网 cert

# 添加 解析 条目
vi /etc/hosts
192.168.164.190 nginx164190.zk.wh.com

[root@node01 ~]# curl https://nginx164190.zk.wh.com/
curl: (60) Peer\’s Certificate issuer is not recognized.
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a \”bundle\”
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn\’t adequate, you can specify an alternate file
using the –cacert option.

curl -o install_cert_linux.zip http://192.168.164.190:40080/install_cert_linux.zip
unzip install_cert_linux.zip

cd install_cert_linux
./install_cert.sh

rndc

1、953端口是rndc 的端口

2、rndc是监控bind的统计数据用的,同时不需要为了更新某个zone而重启bind

查看 默认的 解析条目

cat /etc/bind/named.conf.default-zones
// prime the server with knowledge of the root servers
zone \”.\” {
type hint;
file \”/usr/share/dns/root.hints\”;
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone \”localhost\” {
type master;
file \”/etc/bind/db.local\”;
};

zone \”127.in-addr.arpa\” {
type master;
file \”/etc/bind/db.127\”;
};

zone \”0.in-addr.arpa\” {
type master;
file \”/etc/bind/db.0\”;
};

zone \”255.in-addr.arpa\” {
type master;
file \”/etc/bind/db.255\”;
};

添加 自己的 解析条目

多台 dns 之间 进行 协同
SOA
NS

# A 代表 解析到 ipv4
@ IN A 127.0.0.1

# A 代表 解析到 ipv6
@ IN AAAA ::1

# ptr 代表 逆向解析
1.0.0 IN PTR localhost.
cat /etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include \”/etc/bind/named.conf.options\”;
include \”/etc/bind/named.conf.local\”;
include \”/etc/bind/named.conf.default-zones\”;

// add you zones
include \”/etc/bind/named.conf.my-zones\”;

# 模仿 /etc/bind/named.conf.default-zones 书写 新的 解析记录
cat > /etc/bind/named.conf.my-zones <<\”EOF\”

zone \”zk.wh.com\” {
type master;
file \”/etc/bind/db.zk.wh.com\”;
};

zone \”192.in-addr.arpa\” {

更新 解析记录
