[轉貼]MyDNS 安裝筆記 for Debian Linux
http://blog.roga.tw/2009/08/25/2292<br><br><p>前置作業：</p>
<p>必須先有一個資料庫(MySQL, PostgreSQL)，並且正確設定帳號密碼。並且安裝 MySQL CLient Library
(套件名稱類似：libmysqlclient16，搜尋方式 apt-cache search libmysqlclient )<br>
<span id="more-2292"></span><br>
安裝步驟：<br>
<code><br>
cd /tmp<br>
wget http://mydns.bboy.net/download/mydns-1.1.0.tar.gz<br>
tar xvfz mydns-1.1.0.tar.gz<br>
</code><br>
下載原始檔，存到 /tmp 之後解壓縮。<br>
<code><br>
cd mydns-1.1.0/<br>
./configure<br>
make<br>
make install<br>
</code><br>
切換到目錄，並且編譯，預設使用 MySQL ，如果 ./configure –without-mysql 代表使用 PostgreSQL 。編譯完成後，會有提示如下：</p>
<pre> ### mydns version 1.1.0 installed!<br> ###<br> ### See the file QUICKSTART if you are in a hurry.<br> ### Otherwise, consult the manual (in doc/).<br> ###<br> ### The MyDNS server program was installed as<br> ### /usr/local/sbin/mydns<br> ###<br> ### Your configuration file should be installed as<br> ### /etc/mydns.conf<br> ### (You can auto-create it with "make conf")<br> ###<br></pre>
<p>編輯 /etc/mydns.conf ，裡面可以修改資料庫的連線設定，以及執行 MyDNS 的使用者和群組(可設定為 nobody/nogroup)。然後利用 mydns 自己的指令新增資料表：<br>
<code><br>
mydns --create-tables | mysql -u root -p dbname<br>
</code><br>
dbname 是您的資料庫的名稱，這個指令會建立 soa 和 rr 兩個資料表。<br>
接著在資料庫中修改欄位屬性：<br>
<code><br>
ALTER TABLE soa ADD COLUMN active ENUM('Y','N') NOT NULL;<br>
ALTER TABLE soa ADD INDEX (active);<br>
ALTER TABLE soa ADD COLUMN xfer CHAR(255) NOT NULL;<br>
</code><br>
然後在 /etc/init.d 裡面建立一個 shell script </p>

<p>執行 /etc/init.d/mydns start 看看能不能跑起來，沒有問題的話，讓服務開機自動啟動：<br>
<code><br>
update-rc.d mydns defaults 21 22<br>
</code><br>
接著複製系統裡面內建的管理介面到 www 目錄下：<br>
<code><br>
cp /tmp/mydns-1.0.0/contrib/admin.php /var/www<br>
</code><br>
接著修改 admin.php ，修改資料庫連線設定。如果把 $auto_update_serial 和 $auto_update_ptr 設定為 1 ，系統會在修改資料的時候，自動增加數值。</p>
