debian 安装方法:

  apt-get install apache2 mysql-server-5.0 php5-common php5-mysql libapache2-mob-php5
  apt-get install apache2 mysql-server-5.0 php5
  apt-get clean
  apt-get install libmysql++-dev
  /etc/init.d/apache2 start
php代码如下:   

$link = mysql_connect("ip", "username", "password");
 if(FALSE == $link)
 {
  echo "Connect database failed!";
 }
 echo "Connect database sucess!";
 mysql_select_db('dbname', $link);

 

运行提示:Fatal error: Call to undefined function: mysql_connect()

原因：mysql不支持php，解决办法:

apt-get install php5-mysql
/etc/init.d/apache2 restart
