Centos安装DirectAdmin教程：
1、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*
2、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 libtool3、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.sh4、DA面板安装过程截图：
根据屏幕提示输入Client ID，License ID，以及主机名。
会核实是否是授权IP，以及DA授权绑定的linux发行版。
选择DA面板将要安装的PHP/Apache等，默认推荐的，选3即可。
开始搜索最快的下载镜像，进入DA编译安装过程。
5、DA面板安装完毕：
