1、基礎配置

1.1 環境說明

Centos 7.5.1804
PDNS 4.1.1
MariaDB 5.5.6

1.2 關閉防火牆和 selinux

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
systemctl stop firewalld.service && systemctl disable firewalld.service
firewall-cmd --state

2、安裝 MariaDB

2.1 安裝 MariaDB

1）更改存儲目錄php

mkdir -p /opt/data/mysql/{data,log}

vim /etc/my.cnf

[mysqld]
datadir=/opt/data/mysql/data
socket=/opt/data/mysql/mysql.sock

[mysqld_safe]
log-error=/opt/data/mysql/log/mariadb.log
pid-file=/opt/data/mysql/mariadb.pid

2）默認安裝的版本爲5.5css

#安裝
yum install -y epel-release yum-plugin-priorities
yum install -y mariadb-server mariadb

#設置目錄權限
cd /opt/data/
chown -R mysql.mysql mysql/

#啓動
systemctl enable mariadb.service
systemctl start mariadb.service

2.2 初始化

1）設置軟鏈接html

ln -s /opt/data/mysql/mysql.sock /var/lib/mysql/mysql.sock

由於改動了mysqld的sock的默認目錄，但mysql_client、mysql_secure_installation這些都沒改，因此作一個軟鏈接。node

2）設置root密碼python

mysql_secure_installation
回車,
y,          #設置root密碼
root密碼,
重複root密碼,
y,          #刪除匿名登入
y,          #禁用root遠程登入
y,          #刪除test庫
y           #刷新權限

2.3 設置字符集

vim /etc/my.cnf

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake

vim /etc/my.cnf.d/client.cnf

[client]
default-character-set=utf8

vim /etc/my.cnf.d/mysql-clients.cnf

[mysql]
default-character-set=utf8

2.4 重啓 MariaDB

systemctl restart mariadb

再次登陸 MariaDB，查看字符集，發現已經是 utf8 了。mysql

mysql -uroot -p
show variables like "%character%";show variables like "%collation%";
exit

3、安裝 PowerDNS

3.1 安裝 PowerDNS

yum install -y pdns pdns-backend-mysql

PowerDNS 的配置文件位於 /etc/pdns/pdns.conflinux

3.2 新建數據庫

mysql -uroot -p
CREATE DATABASE powerdns;
GRANT ALL ON powerdns.* TO 'powerdns'@'localhost' IDENTIFIED BY 'powerdns';
FLUSH PRIVILEGES;

3.3 建立數據庫表

use powerdns;

CREATE TABLE domains (
  id                    INT AUTO_INCREMENT,
  name                  VARCHAR(255) NOT 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,

  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)

  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);

flush privileges;
show databases;
show tables;
exit

3.4 配置PowerDNS

cp /etc/pdns/pdns.conf /etc/pdns/pdns.conf.bak

vim /etc/pdns/pdns.conf

#ttl
default-ttl=300

# backend 
launch=gmysql
gmysql-host=localhost
gmysql-port=3306
gmysql-dbname=powerdns
gmysql-user=powerdns
gmysql-password=powerdns

# pdns API
webserver=yes
webserver-address=0.0.0.0
webserver-allow-from=0.0.0.0/0
webserver-port=8081
api=yes
api-key=wmqpdns
api-logfile=/var/log/pdns-api.log

# id
setgid=pdns
setuid=pdns

說明：default-ttl（默認 ttl 改成5分鐘）和 launch 兩個參數是修改，其餘都爲添加。nginx

3.5 開機啓動

systemctl enable pdns.service
systemctl start pdns.service
systemctl status pdns.service

查看808一、53兩個端口git

netstat -tulnp|grep pdns_server

tcp        0      0 0.0.0.0:8081            0.0.0.0:*               LISTEN      18847/pdns_server   
tcp        0      0 0.0.0.0:53              0.0.0.0:*               LISTEN      18847/pdns_server   
tcp6       0      0 :::53                   :::*                    LISTEN      18847/pdns_server   
udp        0      0 0.0.0.0:53              0.0.0.0:*                           18847/pdns_server   
udp6       0      0 :::53                   :::*                                18847/pdns_server

4、安裝PowerDNS-Admin

4.1 安裝python3.6 + pip

yum install -y epel-release
yum install -y https://centos7.iuscommunity.org/ius-release.rpm
yum install -y python36u python36u-devel python36u-pip
pip3.6 install -U pip
pip install -U virtualenv
rm -f /usr/bin/python3 && ln -s /usr/bin/python3.6 /usr/bin/python3

4.2 安裝構建python庫所需包

1）若是使用 Centos 默認的 mariadb 5.5 版本，安裝以下：github

yum install -y gcc mariadb-devel openldap-devel xmlsec1-devel xmlsec1-openssl libtool-ltdl-devel

2）若是使用mariadb 10.x 版本，安裝以下：

yum install gcc MariaDB-devel MariaDB-shared openldap-devel xmlsec1-devel xmlsec1-openssl libtool-ltdl-devel

4.3 安裝 Nodejs 10

curl -sL https://rpm.nodesource.com/setup_10.x | bash -
curl -sL https://dl.yarnpkg.com/rpm/yarn.repo -o /etc/yum.repos.d/yarn.repo
yum install -y yarn

4.4 建立python3 virtualenv環境

yum install -y git
git clone https://github.com/ngoduykhanh/PowerDNS-Admin.git /opt/web/powerdns-admin
cd /opt/web/powerdns-admin
virtualenv -p python3 flask

激活 python3 環境並安裝python庫（後續操做都是基於python3 環境下操做）

source ./flask/bin/activate
pip install python-dotenv
pip install -r requirements.txt

下載的包臨時存放在 /root/.cache/pip/wheels 目錄下。

4.5 建立數據庫

mysql -u root -p
CREATE DATABASE powerdnsadmin CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON powerdnsadmin.* TO 'pdnsadminuser'@'%' IDENTIFIED BY 'p4ssw0rd';
FLUSH PRIVILEGES;
exit

4.6 配置 config.py

cp config_template.py config.py

vim config.py

#地址改爲0.0.0.0
BIND_ADDRESS = '0.0.0.0'
# 配置數據庫鏈接信息,庫/用戶/密碼是以前手動建立的,不是pdns數據庫
SQLA_DB_USER = 'pdnsadminuser'
SQLA_DB_PASSWORD = 'p4ssw0rd'
SQLA_DB_HOST = 'localhost'
SQLA_DB_NAME = 'powerdnsadmin'
# 開啓MySQL
# DATABASE - MySQL
SQLALCHEMY_DATABASE_URI = 'mysql://'+SQLA_DB_USER+':'+SQLA_DB_PASSWORD+'@'+SQLA_DB_HOST+':'+str(SQLA_DB_PORT)+'/'+SQLA_DB_NAME
# 註釋sqlite
# DATABASE - SQLite
# SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir, 'pdns.db')

4.7 建立表並建立資產文件

一、建立表

export FLASK_APP=app/__init__.py
flask db upgrade

報以下錯：

Traceback (most recent call last):
  File "/opt/web/powerdns-admin/flask/bin/flask", line 10, in <module>
    sys.exit(main())
  File "/opt/web/powerdns-admin/flask/lib/python3.6/site-packages/flask/cli.py", line 894, in main
    cli.main(args=args, prog_name=name)
  File "/opt/web/powerdns-admin/flask/lib/python3.6/site-packages/flask/cli.py", line 557, in main
    return super(FlaskGroup, self).main(*args, **kwargs)
  File "/opt/web/powerdns-admin/flask/lib/python3.6/site-packages/click/core.py", line 696, in main
    _verify_python3_env()
  File "/opt/web/powerdns-admin/flask/lib/python3.6/site-packages/click/_unicodefun.py", line 124, in _verify_python3_env
    ' mitigation steps.' + extra
RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment. Consult https://click.palletsprojects.com/en/7.x/python3/ for mitigation steps.

This system lists a couple of UTF-8 supporting locales that
you can pick from.  The following suitable locales were
discovered: en_US.utf8

解決：

export LC_ALL=en_US.utf8

二、建立資產文件

yarn install --pure-lockfile
flask assets build

4.8 啓動

./run.py

訪問PowerDNS-Admin Web界面：http://192.168.159.128:9191

一、先註冊用戶，第一個用戶將處於管理員角色。

二、第一次登陸時，將被重定向到設置頁面以配置PDNS API信息。

#填入在/etc/pdns/pdns.cof配置的API信息：
PDNS API URL：http://127.0.0.1:8081
PDNS API KEY：wmqpdns

4.9 配置systemd服務

使用systemd管理PowerDNS-Admin

vim /usr/lib/systemd/system/powerdns-admin.service

[Unit]
Description=PowerDNS-Admin
After=network.target

[Service]
User=root
Group=root
WorkingDirectory=/opt/web/powerdns-admin
ExecStart=/opt/web/powerdns-admin/flask/bin/gunicorn --workers 2 --bind unix:/opt/web/powerdns-admin/powerdns-admin.sock app:app

[Install]
WantedBy=multi-user.target

啓動Powerdns-Admin服務並將其設置爲在啓動時啓動：

systemctl daemon-reload
systemctl start powerdns-admin
systemctl enable powerdns-admin

能夠運行systemctl status powerdns-admin命令確認狀態是否正在運行，沒問題的話會返回相關的成功信息。

systemctl status powerdns-admin

4.10 安裝nginx

yum install -y nginx

配置nginx

vim /etc/nginx/conf.d/powerdns-admin.conf

server {
  listen *:80;
  server_name               192.168.159.128;

  index                     index.html index.htm index.php;
  root                      /opt/web/powerdns-admin;
  access_log                /var/log/nginx/powerdns-admin.local.access.log combined;
  error_log                 /var/log/nginx/powerdns-admin.local.error.log;

  client_max_body_size              10m;
  client_body_buffer_size           128k;
  proxy_redirect                    off;
  proxy_connect_timeout             90;
  proxy_send_timeout                90;
  proxy_read_timeout                90;
  proxy_buffers                     32 4k;
  proxy_buffer_size                 8k;
  proxy_set_header                  Host $host;
  proxy_set_header                  X-Real-IP $remote_addr;
  proxy_set_header                  X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_headers_hash_bucket_size    64;

  location ~ ^/static/  {
    include  /etc/nginx/mime.types;
    root /opt/web/powerdns-admin/app;

    location ~*  \.(jpg|jpeg|png|gif)$ {
      expires 365d;
    }

    location ~* ^.+.(css|js)$ {
      expires 7d;
    }
  }

  location / {
    proxy_pass            http://unix:/opt/web/powerdns-admin/powerdns-admin.sock;
    proxy_read_timeout    120;
    proxy_connect_timeout 120;
    proxy_redirect        off;
  }
}

啓動nginx

nginx -t
systemctl restart nginx
systemctl enable nginx

瀏覽器訪問 192.168.159.128 便可打開powerdns-admin登入頁

注意：若是添加 new domain 時候提示 400 錯誤，應該是添加的域名格式不對（可能後面有空格）。

4.11 集成OpenLADP

LDAP URI : ldap://192.168.159.130:389
LDAP Base DN : ou=People,dc=wmqe,dc=com
LDAP admin username : cn=admin,dc=wmqe,dc=com
LDAP admin password : ••••••••
Basic filter : (objectClass=inetOrgPerson)
Username field : cn

或者：ldaps://192.168.159.130:636

5、提供域名解析服務

配置子域名解析，可直接在公網生效，不用在本地指定DNS地址。經過配置NS記錄做爲子域名向外提供服務，後續將三級子域名設置爲DNS提供域名解析。

5.1 註冊域名，並配置解析記錄

因NS記錄不能直接指定IP，需先配置A記錄，再配置NS記錄。

1）註冊域名 wmqxxxxx.com

2）配置A記錄，指定到pdns的外網IP（確保53端口的tcp,udp協議都開放）

pdns.wmqxxxxx.com --> 54.223.118.175

3）配置NS記錄，指定到前面建立的A記錄

prod.wmqxxxxx.com --> pdns.wmqxxxxx.com

5.2 配置pdnsadmin

1）添加domain

添加以前NS記錄做爲domain：prod.wmqxxxxx.com

2）添加A記錄解析（記得要點右上角的Apply Changes）

pdnsadmin -> 172.31.57.1

3）這樣就能夠經過 pdnsadmin.prod.wmqxxxxx.com 這個域名訪問內網172.31.57.1地址的服務了，用dig命令測試下效果：

dig pdnsadmin.prod.wmqxxxxx.com

; <<>> DiG 9.13.7 <<>> pdnsadmin.prod.wmqxxxxx.com
