安装DA需要纯净的系统，之前有些朋友安装DA报错，请先执行：yum remove httpd* mysql* php*
1、预安装DA需要的环境：
yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio libcom_err-devel libcurl-devel gd zlib-devel zip unzip libcap-devel cronie bzip2 db4-devel cyrus-sasl-devel perl-ExtUtils-Embed autoconf automake libtool
2、从官方下载setup.sh安装脚本安装DirectAdmin面板：
wget http://www.directadmin.com/setup.sh
chmod 755 setup.sh
./setup.sh
3、安装经典的Capri皮肤：
wget http://licensepad.googlecode.com/files/capri.sh;sh capri.sh
