How to Install and Configure ‘PowerDNS’ (with MariaDB) and ‘PowerAdmin’ in RHEL/CentOS 7
|
||||
RHEL/CentOS 7中安装并配置‘PowerDNS’（与MariaDB搭配）和‘PowerAdmin’
|
||||
================================================================================
|
||||
PowerDNS is a DNS server running on many Linux/Unix derivatives. It can be configured with different backends including BIND style zone files, relational databases or load balancing/failover algorithms. It can also be setup as a DNS recursor running as a separate process on the server.
|
||||
PowerDNS是一个运行在许多Linux/Unix衍生版上的DNS服务器，它可以使用不同的后端进行配置，包括BIND类型的区域文件、相关的数据库，或者负载均衡/失效转移算法。它也可以被配置成一台DNS递归器，作为服务器上的一个独立进程运行。
|
||||
|
||||
The latest version of PowerDNS Authoritative server is 3.4.4, but the one available in the EPEL repository right now is 3.4.3. I would recommend installing the one for the EPEL repository due to the fact that this version is tested in CentOS and Fedora. That way you will also be able to easily update PowerDNS in future.
|
||||
PowerDNS授权服务器的最新版本是3.4.4，但是当前EPEL仓库中可以获得的版本是3.4.3。我推荐安装EPEL仓库中提供的那一个，因为该版本已经在CentOS和Fedora中测试过。那样，你也可以在今后很容易地更新PowerDNS。

#### 6. The configuration file for PowerDNS is located in `/etc/pdns/pdns`, but before editing it, we will setup a MySQL database for PowerDNS service. First we will connect to the MySQL server and will create a database with name powerdns: ####
|
||||
#### 6. PowerDNS的配置文件位于`/etc/pdns/pdns`，在编辑之前，我们将为PowerDNS服务配置一个MySQL数据库。首先，我们将连接到MySQL服务器并创建一个名为powerdns的数据库： ####

### Step 2: Installing PowerAdmin to Manage PowerDNS ###
|
||||
### 步骤 2： 安装PowerAdmin来管理PowerDNS ###
|
||||
|
||||
#### 11. Now we will install PowerAdmin – a friendly web interface designed to manager PowerDNS servers. Since it is written in PHP, we will need to install PHP and a web server (Apache): ####
|
||||
#### 11. 现在，我们将安装PowerAdmin——一个友好的网页接口PowerDNS服务器管理器。由于它是用PHP写的，我们将需要安装PHP和一台网络服务器（Apache）： ####
|
||||
|
||||
# yum install httpd php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mhash gettext

|
||||
|
||||
Once the install is complete, we will need to start and set Apache to start at system boot:
|
||||
安装完成后，我们将需要启动并设置Apache开机启动：
|
||||
|
||||
# systemctl enable httpd.service
|
||||
# systemctl start httpd.service
|
||||
|
||||
|
||||
Enable Start Apache System Boot
|
||||
启用Apache开机启动
|
||||
|
||||
#### 12. Now that all system requirements for running PowerAdmn are met, we can proceed and download the package. Since the default web directory for Apache is /var/www/html/, we will download the package in there. ####
|
||||
#### 12. 由于已经满足PowerAdmin的所有系统要求，我们可以继续下载软件包。因为Apache默认的网页目录位于/var/www/html/，我们将下载软件包到这里。 ####
|
||||
|
||||
# cd /var/www/html/
|
||||
# wget http://downloads.sourceforge.net/project/poweradmin/poweradmin-2.1.7.tgz

||||
#### 15. Since we already created one, we can proceed to the next step. You will be asked to enter the database details you setup earlier. You will also need to setup Poweradmin administrator password: ####
|
||||
#### 15. 因为我们已经创建了一个，所以我们可以继续进入下一步。你会被要求提供先前配置的数据库详情，你也需要为Poweradmin设置管理员密码： ####
|
||||
|
||||
|
||||
Enter PowerDNS Database Settings
|
||||
输入PowerDNS数据库配置

||||
#### 16. 输入这些信息后，进入步骤 4。你将创建为Poweradmin创建一个受限用户。这里你需要输入的字段是： ####
|
||||
|
||||
- Username - username for hte PowerAdmin.
|
||||
- Password – password for the above user.
|
||||
- Hostmaster - When creating SOA records and you have not specified hostmaster, this value will be used.
|
||||
- Secondary nameserver – the value will be used as primary name server when creating new DNS zones.
|
||||
- 用户名 - PowerAdmin用户名。
|
||||
- 密码 – 上述用户的密码。
|
||||
- 注册人 - 当创建SOA记录而你没有制定注册人时，该值会被使用。
