1.安装
1.1.Dockerfile
这个镜像自带webmin，不需要手动安装；手动安装webmin参考官网：https://webmin.com/download/
FROM sameersbn/bind
# 复制自定义的配置文件
COPY named.conf.options /etc/bind/named.conf.options
COPY named.conf.local /etc/bind/named.conf.local
# 暴露 DNS 服务端口
EXPOSE 53
# 启动 BIND 服务
CMD ["/usr/sbin/named", "-g"]
1.2 named.conf.options
options {
directory "/var/cache/bind";
dnssec-validation auto;
recursion yes;
allow-query { any; };
# allow-query-cache { any; };
listen-on { any; };
listen-on-v6 { any; };
max-cache-ttl 3600;
forwarders {
8.8.8.8;
};
};
1.3 named.conf.local
zone "test.com" {
type master;
file "/var/lib/bind/test.com.hosts";
};
zone "test.net" {
type forward;
forward only;
forwarders { 8.8.8.8; };
};
1.4启动
docker build -t bind9 .
docker run --name bind9 -d --restart=always \
--publish 9000:53/tcp --publish 9000:53/udp --publish 10000:10000/tcp \
bind9
检查启动情况：docker ps
如果一直在重启，查看日志：docker logs bind9
2.配置
2.1控制台
启动成功后，访问端口10000可进入控制台。初始账号密码：root/password
参考：https://juejin.cn/post/7147536857298993189

2.2反向解析
在/etc/bind/named.conf.default-zones下添加配置
zone "2.0.192.in-addr.arpa" IN {
type master;
file "/etc/bind/2.0.192.in-addr.arpa";
allow-update { none; };
};
在上面配置的file路径下创建文件，也可以docker打包时复制到容器中。
$TTL 604800
@ IN SOA ns1.example.com. admin.example.com. (
3 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns1.example.com.
;
$ORIGIN 2.0.192.in-addr.arpa.
2 IN PTR host2.example.com.
100 IN PTR server100.example.com.
;
3.测试
替换成启动时配置的实际ip和port
nslookup -port=9000 b.test.com 0.0.0.0
dig @0.0.0.0 -p 9000 b.test.com
nslookup -port=9000 192.0.2.100 0.0.0.0
dig @0.0.0.0 -p 9000 -x 192.0.2.100
4.监控
4.1 bind_exporter
下载bind_exporter
curl -s https://api.github.com/repos/prometheus-community/bind_exporter/releases/latest | grep browser_download_url | grep linux-amd64 | cut -d '"' -f 4 | wget -qi -
解压&移动
tar xvf bind_exporter*.tar.gz
sudo mv bind_exporter-*/bind_exporter /usr/local/bin
新增bind9配置并重启
(centos)sudo vim /etc/named.conf
(ubuntu)sudo vim /etc/bind/named.conf.options
statistics-channels {
inet 127.0.0.1 port 8053 allow { any; };
};
sudo systemctl restart named
创建Prometheus用户组和用户
sudo groupadd --system prometheus
sudo useradd -s /sbin/nologin --system -g prometheus prometheus
创建systemd配置
sudo tee /etc/systemd/system/bind_exporter.service<<EOF

重启&启动
sudo systemctl daemon-reload
sudo systemctl restart bind_exporter.service
sudo systemctl enable bind_exporter.service
检查
systemctl status bind_exporter.service
sudo ss -tunelp | grep 9153
4.2 Prometheus
创建用户组和用户
sudo groupadd --system prometheus

2.在左侧菜单栏中，点击“Configuration”（配置），然后选择“Data Sources”（数据源）。
3.点击“Add data source”（添加数据源）按钮。
4.在“Type”（类型）下拉菜单中，选择“Prometheus”。
5.在“Name”（名称）字段中，为数据源输入一个有意义的名称，例如“Prometheus Server”。
6.在“URL”字段中，输入 Prometheus 服务器的地址，通常是 http://your-prometheus-server:9090 ，请将 your-prometheus-server 替换为您实际的 Prometheus 服务器的主机名或 IP 地址。
7.（可选）根据您的需求设置其他选项，如访问模式、HTTP 配置等。
8.点击“Save & Test”（保存并测试）按钮。如果配置正确，您应该看到“Data source is working”（数据源正常工作）的消息。
导入
1.在左侧菜单栏仪表板中选择“导入”。
