Bind-DLZ + Django + Mysql DNS管理平台

系统环境:CentOS 6.5 X64

软件版本:

  bind-9.9.5.tar.gz  
  mysql-5.6.16.tar.gz
  Python 2.7.6 
  Django 1.11.x

描述: 数据库安装就不在絮叨,了解运维的同学都应该知道

一.源码安装配置Bind:

1.源码编译安装

 tar -zxvf  bind-9.9.5.tar.gz           #解压压缩包
 cd bind-9.9.5
 ./configure --prefix=/usr/local/bind/  \
 --enable-threads=no \
 --enable-newstats   \
 --with-dlz-mysql    \
 --disable-openssl-version-check
 
 #官网说明强调编译关闭多线程,即--enable-threads=no
 
 make
 make install           #源码编译安装完成

2.环境变量配置

cat >>  /etc/profile  <<EOF 
PATH=$PATH:/usr/local/bind/bin:/usr/local/bind/sbin
export  PATH
EOF

 source  /etc/profile  #重新加载一下环境变量
 named -v           #如下图,说明环境变量正常

3.用户添加授权目录

 useradd  -s  /sbin/nologin  named
 chown  -R named:named /usr/local/bind/

4.配置Bind 注意: bind 的数据库即是 管理平台使用的数据库,这里配置的库名和,后面管理平台的数据库名一样

vi /usr/local/bind/etc/named.conf

	options {
			directory       "/usr/local/bind/";
			version         "bind-9.9.9";
			listen-on port 53 { any; };
			allow-query-cache { any; };
			listen-on-v6 port 53 { ::1; };
			allow-query     { any; };
			recursion yes;    
			dnssec-enable yes;
			dnssec-validation yes;
			dnssec-lookaside auto;

	};
	 
	 
	key "rndc-key" {
			algorithm hmac-md5;
			secret "C4Fg6OGjJipHKfgUWcAh+g==";

	};
	 
	controls {
			inet 127.0.0.1 port 953
					allow { 127.0.0.1; } keys { "rndc-key"; };
	};
	 
	 
	view "ours_domain" {
			match-clients           {any; };
			allow-query-cache           {any; };
			allow-recursion          {any; };
			allow-transfer          {any; };
	 
			dlz "Mysql zone" {
					database        "mysql
					{host=127.0.0.1 dbname=devops1 ssl=false port=3306 user=root pass=123456}
					{select zone from dns_records where zone='$zone$'}
					{select ttl, type, mx_priority, case when lower(type)='txt' then concat('\"', data, '\"') when lower(type) = 'soa' then concat_ws(' ', data, resp_person, serial, refresh, retry, expire, minimum) else data end from dns_records where zone = '$zone$' and host = '$record$'}"; 
			};
			zone "."  IN {
				type hint;
				file "/usr/local/bind/etc/named.ca";
			};
	 
	};

保存退出

5.生成 name.ca文件

(demo) -bash-4.1# cd /usr/local/bind/etc/
(demo) -bash-4.1# dig -t NS .  >named.ca

二.配置Bind-Web 管理平台

1.克隆管理平台

(demo) -bash-4.1# git  clone  https://github.com/1032231418/Bind-Web.git  #git  克隆下来
(demo) -bash-4.1# cd Bind-Web

2.安装Django框架

(demo) -bash-4.1# pip instal -r  requirement.txt

3.数据库配置:

    1.)   CREATE DATABASE  devops1   CHARACTER SET utf8 COLLATE utf8_general_ci;  #创建数据库
	
    2.)配置文件devops/settings 里连接数据库
	
			DATABASES = {
				'default': {
					'ENGINE': 'django.db.backends.mysql',
					'NAME':'devops1',
					'USER': 'root',
					'PASSWORD': '123456',
					'HOST': '127.0.0.1',
					'PORT':'3306',
				}
			}
			
    3.)表结构刷到数据库

			 python  manage.py makemigrations

image

			 python  manage.py migrate		

image

    4.)创建管理用户
	
			 (env) [root@pyvm devops]# python manage.py  createsuperuser  

image

    5.)运行项目
	
			 (env) [root@pyvm devops]# python manage.py  runserver 0.0.0.0:8001

http://ip/8001 访问WEB 界面 登录账户就是创建的管理用户

三.启动Bind服务并设置开机启动脚本

1.启动 Bind 服务并设置开机启动脚本

(demo) -bash-4.1# /usr/local/bind/sbin/named

2.监控系统日志:

 tail -f /var/log/messages

3.如下,说明服务启动正常

测试bind连接数据库是否正常:

4.设置 Bind 开机启动脚本

bind 本文档会附带,传到服务器  /etc/init.d/ 目录
(demo) -bash-4.1# chmod  755 /etc/init.d/bind 
(demo) -bash-4.1# #mkdir  /var/run/named/ && chown  named:named -R /var/run/named 
杀掉 named  服务,改用脚本启动

(demo) -bash-4.1# pkill  named
(demo) -bash-4.1# /etc/init.d/bind  start            #监控日志,查看启动状态
(demo) -bash-4.1# chkconfig  --add bind            #加入开机启动

tail -f /var/log/messages
