RHEL/CentOS 7-de PowerDNS (MariaDB bilen) we PowerAdmin-i nädip gurmaly we sazlamaly
PowerDNS köp Linux/Unix önümlerinde işleýän DNS serweridir. BIND stil zolagy faýllary, baglanyşyk bazalary ýa-da ýük balansy/ýalňyş algoritmleri ýaly dürli arka taraplar bilen düzülip bilner. Şeýle hem serwerde aýratyn amal hökmünde işleýän DNS rekursory hökmünde gurup bolýar.
PowerDNS Awtoritet serweriniň iň soňky wersiýasy 3.4.4, ýöne häzirki wagtda EPEL ammarynda bar bolan wersiýa 3.4.3. Bu wersiýanyň CentOS we Fedora-da synagdan geçirilendigi sebäpli EPEL ammary üçin birini gurmagy maslahat bererin. Şeýlelik bilen, geljekde PowerDNS-ni aňsatlyk bilen täzeläp bilersiňiz.
Bu makala size MariDB arkasy we PowerAdmin - PowerDNS üçin dostlukly web interfeýs dolandyryş guraly bolan PowerDNS serwerini nädip gurmalydygyny we gurmalydygyny görkezmekçi.
Bu makalanyň maksady bilen:
Hostname: centos7.localhost IP Address 192.168.0.102
1-nji ädim: MariaDB Backend bilen PowerDNS gurmak
1. Ilki bilen serweriňiz üçin EPEL ammaryny işletmeli:
# yum install epel-release.noarch
2. Indiki ädim, MariaDB serwerini gurmak. Muny aşakdaky buýrugy işletmek arkaly aňsatlyk bilen edip bolýar:
# yum -y install mariadb-server mariadb
3. Indiki, ulgam ýüklemesini işletmek we başlamak üçin MySQL-y düzeris:
# systemctl enable mariadb.service # systemctl start mariadb.service
4. Indi MySQL hyzmaty işleýänsoň, işledip, MariaDB üçin paroly gorarys we gurarys:
# mysql_secure_installation
/bin/mysql_secure_installation: line 379: find_mysql_client: command not found
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): Press ENTER
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password: ← Set New Password
Re-enter new password: ← Repeat Above Password
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y ← Choose “y” to disable that user
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n ← Choose “n” for no
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y ← Choose “y” for yes
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y ← Choose “y” for yes
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
5. MariaDB konfigurasiýasy üstünlikli ýerine ýetirilenden soň, PowerDNS gurmak bilen dowam edip bileris. Bu aňsatlyk bilen ylgamak bilen tamamlanýar:
# yum -y install pdns pdns-backend-mysql
6. PowerDNS üçin konfigurasiýa faýly /etc/pdns/pdns -da ýerleşýär, ýöne redaktirlemezden ozal PowerDNS hyzmaty üçin MySQL maglumat bazasyny gurarys. Ilki bilen MySQL serwerine birikeris we powerdns ady bilen maglumat bazasyny dörederis:
# mysql -u root -p MariaDB [(none)]> CREATE DATABASE powerdns;
7. Indiki, powerdns atly maglumat bazasy ulanyjysyny dörederis:
MariaDB [(none)]> GRANT ALL ON powerdns.* TO 'powerdns'@'localhost' IDENTIFIED BY 'tecmint123'; MariaDB [(none)]> GRANT ALL ON powerdns.* TO 'powerdns'@'centos7.localdomain' IDENTIFIED BY 'tecmint123'; MariaDB [(none)]> FLUSH PRIVILEGES;
Bellik: Gurmak üçin ulanmak isleýän hakyky parolyňyz bilen\tecmint123 çalyşyň.
8. PowerDNS tarapyndan ulanylýan maglumat bazasynyň tablisalaryny döretmäge dowam edýäris. Şol bloklary blok bilen ýerine ýetiriň:
MariaDB [(none)]> USE powerdns; MariaDB [(none)]> 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) );
MariaDB [(none)]> CREATE UNIQUE INDEX name_index ON domains(name); MariaDB [(none)]> CREATE TABLE records ( id INT auto_increment, domain_id INT DEFAULT NULL, name VARCHAR(255) DEFAULT NULL, type VARCHAR(6) DEFAULT NULL, content VARCHAR(255) DEFAULT NULL, ttl INT DEFAULT NULL, prio INT DEFAULT NULL, change_date INT DEFAULT NULL, primary key(id) );
MariaDB [(none)]> CREATE INDEX rec_name_index ON records(name); MariaDB [(none)]> CREATE INDEX nametype_index ON records(name,type); MariaDB [(none)]> CREATE INDEX domain_id ON records(domain_id);
MariaDB [(none)]> CREATE TABLE supermasters ( ip VARCHAR(25) NOT NULL, nameserver VARCHAR(255) NOT NULL, account VARCHAR(40) DEFAULT NULL );
Indi MySQL konsolyndan ýazyp bilersiňiz:
MariaDB [(none)]> quit;
9. Ahyrynda, PowerDNS-i MySQL-i arka görnüşinde ulanjak görnüşde düzüp bileris. Şol maksat bilen ýerleşýän PowerDNS konfigurasiýa faýlyny açyň:
# vim /etc/pdns/pdns.conf
Şol faýlda şuňa meňzeş setirleri gözläň:
################################# # launch Which backends to launch and order to query them in # # launch=
Şondan soň aşakdaky kody goýuň:
launch=gmysql gmysql-host=localhost gmysql-user=powerdns gmysql-password=user-pass gmysql-dbname=powerdns
Öň bellän hakyky parolyňyz bilen\ulanyjy-geçişini üýtgediň. Ine, konfigurasiýamyň görnüşi:
Üýtgeşmäňizi saklaň we çykyň.
10. Indi PowerDNS-i ulgam ýüklemesinden başlap hyzmatlaryň sanawyna goşarys:
# systemctl enable pdns.service # systemctl start pdns.service
Bu wagt PowerDNS serweriňiz işleýär we işleýär. PowerDNS hakda has giňişleýin maglumat üçin http://downloads.powerdns.com/documentation/html/index.html
