刷新服务

cd /free_cicdfs/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_cicdfs/data/bind9/etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind/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_cicdfs/data/bind9/etc/bind/named.conf.options <<"EOF"
 
# include "/etc/rndc.key";
 
controls {
    inet.0.0.1 port 953
    allow {.0.0.1; } keys { "rndckey"; };
};
 
options {
    
    // set no
    dnssec-enable no;
    dnssec-validation no;
 
    listen-on port { any; };
 
    allow-query { any; };
 
    forwarders {.114.114.114;
    };
};
 
EOF
 
chmod -R  /free_cicdfs0/data/bind9/
chown root:root -R  /free_cicdfs/data/bind9/
 
chown root:named -R  /free_cicdfs/data/bind9/
 
docker-compose up -d 
# log error
couldn't add command channel.0.0.1#953: file not found
docker cp -a bind:/etc/bind  /free_cicdfs0/data/bind9/etc/
 
docker cp -a bind:/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#53
 
解决:
由于是局域网内非法DNS,所以将DNS安全关闭.
[root@-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_cicdfs/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
 
zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};

https://nginx164190.zk.wh.com/

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.168.164.190  nginx164190.zk.wh.com
 
[root@node ~]# curl https://nginx164190.zk.wh.com/
curl: () 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://.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
 
zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};
 
zone ".in-addr.arpa" {
        type master;
        file "/etc/bind/db.";
};

添加 自己的 解析条目

# A 代表 解析到 ipv
@       IN      A.0.0.1
 
# A 代表 解析到 ipv

# ptr 代表 逆向解析.0.0   IN      PTR     localhost.
cat /etc/bind/named.conf

include "/etc/bind/named.conf.options";

// add you zones
