Bind-DLZ + Django + Mysql DNS 主从管理平台

Geek Repo:Geek Repo

Github PK Tool:Github PK Tool

Bind-DLZ + Django + Mysql DNS管理平台

系统环境:CentOS 7.6 X64

软件版本:

  bind-9.11.6.tar.gz  
  mysql-5.6.16.tar.gz
  Python 3.6 
  Django 1.11.x

一．源码安装配置Bind: 

yum -y install make gcc-c++ cmake bison-devel  ncurses-devel python-devel python-ply bind-utils
./configure --prefix=/usr/local/bind/ \
--with-dlz-mysql=/usr/local/mysql \
--enable-threads=no --enable-largefile \
--disable-ipv6 --with-openssl=no
make && make install

1.用户添加授权目录

 mkdir -p /usr/local/bind/var/{logs,zones}
 cd /usr/local/bind/etc/
 /usr/local/bind/sbin/rndc-confgen > rndc.conf
 tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf
 useradd  -s  /sbin/nologin  named
 chown  -R named:named /usr/local/bind/

2.配置Bind

# 配置主服务器
vim /usr/local/bind/etc/named.conf # 主

   algorithm hmac-md5;
   secret "mvCUyhyDvNNGywhoVHbSaQ==";

                 allow { 127.0.0.1; } keys { "rndc-key"; };
};

acl trust-lan {
        172.0.0.0/8;
};

    statistics-file "/usr/local/bind/var/bind.stats";

二．配置Bind-Web 管理平台

1.获取代码

git  clone  https://github.com/ymx8383521/Bind-Web.git  #git  克隆下来
cd Bind-Web
pip install -r  requirement.txt

2.数据库配置

    1.)   CREATE DATABASE db_ops CHARACTER SET utf8 COLLATE utf8_general_ci;  #创建数据库
      grant all privileges on db_ops.* to op_oss@'%' identified by 'JqIrsM1hVvo8'
	
    2.)配置文件devops/settings 里连接数据库
	
            DATABASES = {
                'default': {
                    'ENGINE': 'django.db.backends.mysql',
                    'NAME':'db_ops',
                    'USER': 'op_oss',
                    'PASSWORD': 'JqIrsM1hVvo8',
                    'HOST': '127.0.0.1',
                    'PORT':'3306',
                }
            }
			
    3.)表结构刷到数据库
            python  manage.py makemigrations 
            python  manage.py migrate
            python manage.py  createsuperuser
			 
    4.)运行项目
            python manage.py  runserver 0.0.0.0:8001

    5.)访问WEB 界面 登录账户就是创建的管理用户
            http://ip/8001

三. 针对已有数据库的操作

##### # 把新生成的models.py放到app目录下 
python manage.py inspectdb > models.py  #需要修改managed = True  
python manage.py migrate
# 数据库构
create table `t_dns_records` (
  `id` bigint(20) not null auto_increment comment '主健',
  `zone` varchar(255) not null default '' comment '域名',
  `host` varchar(255) not null default '' comment '记录名称',
  `type` varchar(255) not null default '' comment '记录类型',
  `data` varchar(255) not null default '' comment '记录值',
  `ttl` int(11) default null comment 'ttl(存活时间)',
  `mx_priority` int(11) default null comment 'mx优先级',
  `refresh` int(11) default null comment '刷新时间间隔',
  `retry` int(11)  default null comment '重试时间间隔',
  `expire` int(11) default null comment '过期时间',
  `minimum` int(11) default null comment '最小时间',
  `serial` bigint(20) default null comment '序列号,每次更改配置都会在原来的基础上加1',
  `resp_person` varchar(64) default null comment '责任人',
  `primary_ns` varchar(64) default null comment '主域名',
  `status` tinyint(4) default 1 comment '0:该记录无效, 1:该记录有效',
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updated_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  primary key (`id`),
  key `ix_zone` (`zone`),
  key `ix_host` (`host`),
  key `ix_data` (`data`),
  key `ix_type` (`type`),
  key `ix_status` (`status`),
  key `ix_created_at` (`created_at`),
  key `ix_updated_at` (`updated_at`)
) engine=InnoDB default charset=utf8 comment='DNS解析记录';

create table `t_dns_xfr_table` (
  `id` bigint(20) not null auto_increment comment '主健',
  `zone` varchar(255) not null default '' comment '域名',
  `client` varchar(255) not null default '' comment 'BIND SLAVE 客户端',
  `status` tinyint(4) default 1 comment '0:该记录无效, 1:该记录有效',
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updated_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  primary key (`id`),
  key `ix_created_at` (`created_at`),
  key `ix_updated_at` (`updated_at`)
) engine=InnoDB default charset=utf8 comment='DNS授权传送信息';

四．Bind-Web使用

参考：http://wiki.vknow.com/display/yunwei/bind

  1. slave配置zone

    zone "php.com." in {
    type slave;
    file "zones/php.com";
    masterfile-format text;
    masters{ 172.28.10.60; };
    };

  2. Bind-Web平台上操作，首先要创建SOA记录和NS记录

    select * from t_dns_records limit 3;
    +----+-----------+------+------+------------- -+-----+-------------+---------+-------+--------+---------+------------+-------------+------------+--------+---------------------+---------------------+ | id | zone | host | type | data | ttl | mx_priority | refresh | retry | expire | minimum | serial | resp_person | primary_ns | status | created_at | updated_at | +----+-----------+------+------+---------------+-----+-------------+---------+-------+--------+---------+------------+-------------+------------+--------+---------------------+---------------------+ | 1 | baidu.com | @ | NS | ns.baidu.com. | 60 | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | 1 | 2019-07-01 11:02:14 | 2019-07-11 19:10:54 | | 2 | baidu.com | @ | SOA | ns | 60 | NULL | 300 | 3000 | 86400 | 86400 | 1562898308 | admin | NULL | 1 | 2019-07-01 11:02:28 | 2019-07-12 10:25:12 | | 3 | baidu.com | xxxx | A | 172.20.10.72 | 60 | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | 1 | 2019-07-01 11:05:44 | 2019-07-11 19:10:54 | +----+-------- --+------+------+---------------+-----+-------------+---------+-------+--------+---------+------------+-------------+------------+--------+---------------------+---------------------+

    select * from t_dns_xfr_table limit 1;
    +----+-----------+--------------+--------+---------------------+---------------------+
    | id | zone | client | status | created_at | updated_at |
    +----+-----------+--------------+--------+---------------------+---------------------+
    | 1 | baidu.com | 172.20.10.61 | 1 | 2019-07-01 11:01:46 | 2019-07-01 11:01:46 |
    +----+-----------+--------------+--------+---------------------+---------------------+
