Часть 1. Установка и настройка авторитарного DNS сервера на основе решения PowerDNS
Добрый день!
В этой статье я опишу настройку авторитарного DNS сервера, на основе решения PowerDNS. PowerDNS — высокопроизводительный, бесплатный DNS сервер с открытым исходным кодом. Для сравнения, mail.ru использует PowerDNS как держатель своих зон.
PowerDNS — представляет собой высокопроизводительный DNS-сервер, написанный на C++ и лицензируемый под лицензией GPL. Разработка ведётся в рамках поддержки Unix-систем; Windows-системы более не поддерживаются.
Сервер разработан в голландской компании PowerDNS.com Бертом Хубертом и поддерживается сообществом свободного программного обеспечения.
PowerDNS использует гибкую архитектуру хранения/доступа к данным, которая может получать DNS информацию с любого источника данных. Это включает в себя файлы, файлы зон (англ.) BIND, реляционные базы данных или директории LDAP.
PowerDNS по умолчанию настроен на обслуживание запросов из БД.
После выхода версии 2.9.20 программное обеспечение распространяется в виде двух компонентов — (Authoritative) Server (авторитарный DNS) и Recursor (рекурсивный DNS).
Итак, начнем все с чистой операционной системы CentOS, скачанной с официального сайта www.centos.org.
Конфигурация моего оборудования:
HDD: 15Gb
RAM: 16Gb
CPU: 8×2,4GHz
OS: CentOS 7 (x64)
Дистрибутив: CentOS-7-x86_64-Minimal-1503–01.iso
1) Обновляем систему и подключаем репозитории:
yum update -y
yum clean all
rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
Проверяем:
yum repolist
2) Устанавливаем различные полезные утилиты
yum install net-tools wget bind-utils tcpdump unzip -y
3) Отключение firewalld и устанавливаем iptables
systemctl stop firewalld
systemctl disable firewalld
yum -y install iptables-services
systemctl enable iptables.service
systemctl start iptables.service
iptables -L -v -n
Создаем правила для файервола
vi /etc/sysconfig/iptables
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -i eno160 -j ACCEPT
-A INPUT -i eno192 -p tcp -m state --state NEW --dport 53 -j ACCEPT
-A INPUT -i eno192 -p udp -m state --state NEW --dport 53 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
-P INPUT DROP
COMMIT
И перезагружаем iptables
service iptables restart
4) Создаем папку со скриптами для управления
mkdir /script
vi /script/reload.sh
service pdns restart
service httpd restart
chmod +x /script/*.sh
5) Устанавливаем MariaDB
Добавляем репозиторий.
sudo vi /etc/yum.repos.d/MariaDB.repo
Вставляем в файл следующие строки:
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
Устанавливаем
yum install MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared postgresql-devel -y
Стартуем mysql
sudo /etc/init.d/mysql start
Затем выполните следующую команду, чтобы защитить сервер базы данных.
sudo mysql_secure_installation
Затем выберите «Y» (Да) для остальных подсказок, пока вы не закончите.
Enter current password for root (enter for none): press Enter
Set root password? Y
New password: Type new root password
Re-enter new password: Confirm the password
Remove anonymous users? Y
Disallow root login remotely? Y
Remove test database and access to it? Y
Reload privilege tables now? Y
Последнее, необходимо заменить cnf.ini файл по умолчанию в /etc/ для MariaDB. Но для начала нужно перейти в:
cd /usr/share/mysql
И использовать один из предопределенных cnf.ini конфигураций которые доступны (Huge, Medium и Small) в данной папке.
Сделаем резервное копирование cnf.ini файла:
sudo mv /etc/cnf.ini /etc/cnf.ini.bak
Затем скопируйте один из предварительных конфигураций в MariaDB:
sudo cp /usr/share/mysql/my-huge.cnf /etc/cnf.ini
Перезапускаем MariaDB и добавляем в автозапуск
sudo /etc/init.d/mysql restart
systemctl status mysql
systemctl enable mysql
ss -tnlp | grep 3306
netstat -tap | grep mysql
Мне нужно создать пользователя и чтобы он мог подключатся из любого компьютера, для этого:
mysql -u root -p
GRANT ALL PRIVILEGES ON *.* TO 'imperituroard'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
exit
Можно попробовать подключиться к базе данных, например с помощью программы Navicat Premium.
6) Создание и настройка базы данных для PowerDNS
Описано на официальном сайте doc.powerdns.com/md/authoritative/howtos/#basic-setup-configuring-database-connectivity
Создаем файл pdns.sql в /root и выполняем команду:
mysql -u root -p < /root/pdns.sql
CREATE DATABASE powerdns character set utf8;
GRANT ALL ON powerdns.* TO 'imperituroard'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
USE powerdns;
CREATE TABLE domains (
id INT AUTO_INCREMENT,
name VARCHAR(255) NOT NULL,
master VARCHAR(128) DEFAULT NULL,
last_check INT DEFAULT NULL,
type VARCHAR(6) NOT NULL,
notified_serial INT DEFAULT NULL,
account VARCHAR(40) DEFAULT NULL,
PRIMARY KEY (id)
) Engine=InnoDB;
CREATE UNIQUE INDEX name_index ON domains(name);
CREATE TABLE records (
id INT AUTO_INCREMENT,
domain_id INT DEFAULT NULL,
name VARCHAR(255) DEFAULT NULL,
type VARCHAR(10) DEFAULT NULL,
content VARCHAR(64000) DEFAULT NULL,
ttl INT DEFAULT NULL,
prio INT DEFAULT NULL,
change_date INT DEFAULT NULL,
disabled TINYINT(1) DEFAULT 0,
ordername VARCHAR(255) BINARY DEFAULT NULL,
auth TINYINT(1) DEFAULT 1,
PRIMARY KEY (id)
) Engine=InnoDB;
CREATE INDEX nametype_index ON records(name,type);
CREATE INDEX domain_id ON records(domain_id);
CREATE INDEX recordorder ON records (domain_id, ordername);
CREATE TABLE supermasters (
ip VARCHAR(64) NOT NULL,
nameserver VARCHAR(255) NOT NULL,
account VARCHAR(40) NOT NULL,
PRIMARY KEY (ip, nameserver)
) Engine=InnoDB;
CREATE TABLE comments (
id INT AUTO_INCREMENT,
domain_id INT NOT NULL,
name VARCHAR(255) NOT NULL,
type VARCHAR(10) NOT NULL,
modified_at INT NOT NULL,
account VARCHAR(40) NOT NULL,
comment VARCHAR(64000) NOT NULL,
PRIMARY KEY (id)
) Engine=InnoDB;
CREATE INDEX comments_domain_id_idx ON comments (domain_id);
CREATE INDEX comments_name_type_idx ON comments (name, type);
CREATE INDEX comments_order_idx ON comments (domain_id, modified_at);
CREATE TABLE domainmetadata (
id INT AUTO_INCREMENT,
domain_id INT NOT NULL,
kind VARCHAR(32),
content TEXT,
PRIMARY KEY (id)
) Engine=InnoDB;
CREATE INDEX domainmetadata_idx ON domainmetadata (domain_id, kind);
CREATE TABLE cryptokeys (
id INT AUTO_INCREMENT,
domain_id INT NOT NULL,
flags INT NOT NULL,
active BOOL,
content TEXT,
PRIMARY KEY(id)
) Engine=InnoDB;
CREATE INDEX domainidindex ON cryptokeys(domain_id);
CREATE TABLE tsigkeys (
id INT AUTO_INCREMENT,
name VARCHAR(255),
algorithm VARCHAR(50),
secret VARCHAR(255),
PRIMARY KEY (id)
) Engine=InnoDB;
CREATE UNIQUE INDEX namealgoindex ON tsigkeys(name, algorithm);
7) Устанавливаем PowerDNS autoritative.
Через репозиторий
yum install pdns pdns-backend-mysql pdns-tools pdns-backend-postgresql -y
systemctl enable pdns.service
systemctl start pdns.service
netstat -tap | grep pdns
Либо из исходников
Я устанавливаю из исходников, что и вам советую. Исходники PowerDNS можно найти на github: github.com/PowerDNS/pdns
Устанавливаем необходимые программы для сборки из исходников и выполняем предварительное конфигурирование.
yum install autoconf automake bison flex g++ git libboost-all-dev libtool make pkg-config ragel libmysqlclient-dev unzip
yum groupinstall "Development Tools"
cd /etc/yum.repos.d/
wget http://download.opensuse.org/repositories/home:waziers/CentOS_CentOS-6/home:waziers.repo
wget http://springdale.math.ias.edu/data/puias/unsupported/6/x86_64/ragel-6.6-2.puias6.x86_64.rpm
rpm -i ragel-6.6-2.puias6.x86_64.rpm
yum install -y LuaJIT LuaJIT-devel openssl-devel boost-devel sqlite-devel mysql mysql-devel
wget https://github.com/PowerDNS/pdns/archive/master.zip
unzip master.zip
cd pdns-master
./bootstrap
Далее собираем из исходников PowerDNS и устанавливаем. Также можно посмотреть доступные опции.
cd /root/pdns-master
./configure --help
./configure --with-luajit --with-lua --with-gnu-ld --with-sqlite3 --with-mysql-lib--with-mysql
make
make install
8) Настраиваем конфигурацию авторитативного сервера

#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See for detailed information.
# In particular, see
#
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.

# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
Include conf.modules.d/*.conf
#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User apache
Group apache
# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# definition. These values also provide defaults for
# any containers you may define later in the file.
#
# All of these directives may appear inside containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#
#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed. This address appears on some server-generated pages, such
# as error documents. e.g. admin@your-domain.com
#
ServerAdmin root@localhost
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80
#
# Deny access to the entirety of your server's filesystem. You must
# explicitly permit access to web content directories in other
# blocks below.
#
AllowOverride none
Require all denied
#
# Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#
#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/var/www/html"
#
# Relax access to content within /var/www.
#
AllowOverride None
# Allow open access:
Require all granted
# Further relax access to the default document root:
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.4/mod/core.html#options
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride None
#
# Controls who can get stuff from this server.
#
Require all granted
Order deny,allow
deny from all
allow from 217.21.61.8
allow from 10.128.71.3
allow from 10.135.55.4

#
# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
DirectoryIndex index.html
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
Require all denied
#
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a
# container, that host's errors will be logged there and not here.
#
ErrorLog "logs/error_log"
#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn
#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
#
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
# You need to enable mod_logio.c to use %I and %O
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
#
# The location and format of the access logfile (Common Logfile Format).
# If you do not define any access logfiles within a
# container, they will be logged here. Contrariwise, if you *do*
# define per- access logfiles, transactions will be
# logged therein and *not* in this file.
#
#CustomLog "logs/access_log" common
#
# If you prefer a logfile with access, agent, and referer information
# (Combined Logfile Format) you can use the following directive.
#
CustomLog "logs/access_log" combined
#
# Redirect: Allows you to tell clients about documents that used to
# exist in your server's namespace, but do not anymore. The client
# will make a new request for the document at its new location.
# Example:
# Redirect permanent /foo http://www.example.com/bar
#
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL. You will also likely
# need to provide a section to allow access to
# the filesystem path.
#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client. The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.
#
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
#
# "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
AllowOverride None
Options None
Require all granted
#
# TypesConfig points to the file containing the list of mappings from
# filename extension to MIME-type.
#
TypesConfig /etc/mime.types
#
# AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.
#
#AddType application/x-gzip .tgz
#
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
#
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi
# For type maps (negotiated resources):
#AddHandler type-map var
#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
#
# Specify a default charset for all content served; this enables
# interpretation of all content as UTF-8 by default. To use the
# default browser choice (ISO-8859-1), or to allow the META tags
# in HTML content to override this choice, comment out this
# directive:
#
AddDefaultCharset UTF-8
#
# The mod_mime_magic module allows the server to use various hints from the
# contents of the file itself to determine its type. The MIMEMagicFile
# directive tells the module where the hint definitions are located.
#
MIMEMagicFile conf/magic
#
# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
#
#
# EnableMMAP and EnableSendfile: On systems that support it,
# memory-mapping or the sendfile syscall may be used to deliver
# files. This usually improves server performance, but must
# be turned off when serving from networked-mounted
# filesystems or if support for these functions is otherwise
# broken on your system.
# Defaults if commented: EnableMMAP On, EnableSendfile Off
#
#EnableMMAP off
EnableSendfile on
# Supplemental configuration
#
# Load config files in the "/etc/httpd/conf.d" directory, if any.

12) Финальная настройка
Заходим по адресу 172.24.184.177/poweradmin/install/index.php
Где 172.24.184.177 — IP вашего сервера.
И вводим все предложенные данные.
После завершения установки, удаляем папку /var/www/html/poweradmin/install и заходим в веб интерфейс управления по
адресу 172.24.184.177/poweradmin/index.php
А вот так выглядит веб интерфейс (есть русский язык):
P.S. Эта статья — первая часть моего рассказа. В следующей части я расскажу про дальнейшие настройки, для оптимизации производительности и пр.
