docker使用bind9實現域名解析

Docker

重新整理服務


cd /free_cicdfs0/compose/bind9

docker-compose down; docker-compose up  -d

修改配置檔案

新版本 配置檔案 大致結構發生了一些改變

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";

從 114 快取 查詢 資料


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

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

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

docker-compose up -d 
# log error

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 無法 ping

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

解決:
由於是區域網內非法DNS,所以將DNS安全關閉.
[root@192-168-174-42 ~]# vim /etc/named.conf
將下面的兩項設定為no
        dnssec-enable no;
        dnssec-validation no;

檢視 已經 區域 解析，並新增 新的 解析 項

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.

rndc

1、953埠是rndc 的埠

2、rndc是監控bind的統計資料用的,同時不需要為了更新某個zone而重啟bind
