1. 安裝依賴包

yum install -y lua-devel.x86_64 boost-devel

2. rpm 方法安裝 pdns (注意使用 --nodeps 參數)

[root@gd02-qa-plx2-ddns-web-99 ~]# rpm -ivh  --nodeps pdns-3.3.1-20140128.vipclound.centos65.x86_64.rpm

文件已修複之前上一版本不可以正常啟動 PDNS 問題

安裝後啟動方法

/apps/sh/pdns start

關閉

/apps/sh/pdns stop

4. 確保係統中使用到 mysqlclient.18.0 庫文件, 數據庫授權並導入 sql 腳本

*授權 pdns 用戶能夠訪問 pdns 數據庫

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)

2. 確保係統中使用到 mysqlclient.18.0 庫文件, 數據庫授權並導入 sql 腳本

*授權 pdns 用戶能夠訪問 pdns 數據庫

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> flush privileges;
Query OK, 0 rows affected (0.00 sec)

導入 pdns 所需要的 sql

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

5. 配置 pdns 服務器
/apps/conf/pdns/pdns.conf

daemon=yes
recursor=192.168.86.37
launch=gmysql
gmysql-host=127.0.0.1
gmysql-user=pdns
gmysql-dbname=pdns
gmysql-password=pdns

6. 啟動 pdns 服務器

/apps/sh/pdns start

7. 測試方法

 a. 檢測端口 53/tcp 是否使用中
 b. 檢測防火牆關閉, selinux 關閉
 c. /etc/resolv.conf 是否指向自己
 d. nslookup localhost 是否能夠返回 127.0.0.1

8. nginx 啟動配置忽略, 但需要吧 webroot 指向 /app/dat/web 下

9. 配置 php
隻修改下麵 /apps/conf/php5/php.ini 兩部分

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

執行命令

mkdir /tmp/session
chown apps:apps /tmp/session

10. 啟動 nginx, (啟動 php 略)

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

可通過界麵方法進行配置管理
