###暴雪爸爸开了8.0,我去保卫艾泽拉斯了,很久没有更新。公司用的BIND做的DNS管理,采用了文本格式存储。之前用过BIND+MYSQL+DLZ,对于后面想要自行搭建运维可视化平台的小伙伴来说,确实很方便。但性能问题是个大问题,最后无奈采用通过Dnspython封装的BIND接口,操作BIND的jnl文件进行动态解析。
附上一个dlz和原生bind的性能测试数据(比较老,仅供参考):

效果图如下:

#一、 Jnl文件
jnl 文件(journal文件)是bind动态更新的时候记录更新内容所生成的日志文件。BIND9支持两个授予用户对一个域执行动态更新权限的备选方案,分别由allow-update和update-policy设定。其中allow-update 授于指定用户对域中的任何名称的任何的记录更新的权利。allow-update指定哪些主机允许为主域名服务器提交动态 DNS 更新。默认为拒绝任何主机进行更新,详见百度。

##二、 环境准备

  • Dnspython对应你的python版本,官网http://www.dnspython.org/
  • Django运行版本1.6.1
  • Python运行版本2.7.1

##三、 食用过程
###1.生成TSIG key,修改named.conf添加授权,定义zone文件添加allow-update(详见百度,这里不具体展开)
###2.增删改后端部分代码

# -*- coding: utf8 -*-
import dns.tsigkeyring
import dns.update
import dns.query 
import dns.resolver
keyring = dns.tsigkeyring.from_text({"youth":tsig key密码})
up = dns.update.Update("youth.cn", keyring=keyring)
up .add("test2", 60, 'a', "192.168.183.131")    #添加名称为test2的A记录,TTL时间60,解析地址192.168.183.131
up.delete("test2")  #删除test2记录
up.replace("test2", 360, "CNAME", "test3.youth.cn.")  #将test2修改为CNAME记录,TTL时间360,CNAME地址test3.youth.cn.
dns.query.tcp(up, SERVER_IP)

###3.前端用的Metronic框架,jQuery表格插件用的dataTables,部分前端代码如下:

####这里踩过的坑:
最终公司的DNS惨遭了30G的DD,导致运营商都跟着一起倒霉,后续将NS解析迁移至网宿的云DNS平台,我的平台还是通过网宿的云DNS平台所提供的接口API进行域名解析,BIND只作为内网解析及解析记录汇总(即选择外部解析后,解析记录将存储在我的内部平台上并推送记录到网宿节点,这也是为了将来万一换厂家,直接推送全部记录即可)

####URL监控用的Openfalcon做的,后续会慢慢补上。。。
