Powerdns installation and deployment memo

PowerDNS

A DNS server that supports PHP Web Page Management and allows you to add DNS address records directly to the database, which is flexible and convenient.

Download the ddns package

http://downloads.powerdns.com/releases/pdns-3.3.1.tar.gz

Download the webpage management page

wget https://github.com/downloads/poweradmin/poweradmin/poweradmin-2.1.6.tgz

Decompress the package to the/apps/dat/web directory.

[root@gd02-qa-plxt2-nodomain web]# cd /apps/dat/web[root@gd02-qa-plxt2-nodomain web]# tar xf poweradmin-2.1.6.tgz [root@gd02-qa-plxt2-nodomain web]# mv poweradmin-2.1.6 pdns

The file has fixed the problem that the previous version cannot start PDNS normally.

How to start after installation

/apps/sh/pdns start

Close

/apps/sh/pdns stop

4. Make sure that the mysqlclient.18.0 database file is used in the system, the database is authorized, and the SQL script is imported.

* Authorize the pdns user to access the pdns Database

mysql> create database pdns;Query OK, 1 row affected (0.00 sec)mysql> grant all on pdns.* to 'pdns'@'localhost' identified by 'pdns';Query OK, 0 rows affected (0.00 sec)mysql> grant all on pdns.* to 'pdns'@'127.0.0.1' identified by 'pdns';Query OK, 0 rows affected (0.00 sec)mysql> grant all on pdns.* to 'pdns'@'0.0.0.0' identified by 'pdns';Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

SQL required for importing pdns

[root@station140 mysql5]# /apps/svr/mysql5/bin/mysql -u pdns -ppdns pdns <  /apps/conf/pdns/pdns.sql

5. Configure the pdns Server
/Apps/conf/pdns. conf

daemon=yesrecursor=192.168.86.37launch=gmysqlgmysql-host=127.0.0.1gmysql-user=pdnsgmysql-dbname=pdnsgmysql-password=pdns

6. Start the pdns Server

/apps/sh/pdns start

 

7. Test Method

A. Check whether port 53/tcp is in use. B. Check if the firewall is disabled. If selinux is disabled, c./etc/resolv. conf is directed to its own d. nslookup localhost. If yes, 127.0.0.1 is returned.

8. nginx STARTUP configuration is ignored, but you need to point webroot to/app/dat/web

 

9. Configure php
Modify only the following two parts:/apps/conf/php5/php. ini.

session.save_path = "/tmp/session" date.timezone Asia/Chongqing

 

Execute Command

mkdir /tmp/sessionchown apps:apps /tmp/session

10. Start nginx (start php slightly)

[root@gd02-qa-plxt2-nodomain /]# lsof -i:80COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAMEnginx   3105 root    7u  IPv4  42727      0t0  TCP *:http (LISTEN)nginx   3106 apps    7u  IPv4  42727      0t0  TCP *:http (LISTEN)

Configuration management can be performed through the interface

How to add host records

You can call the add record button to ADD multiple domain names.

 

After adding the data, you can immediately call nslookup for verification. This is very convenient.
