ubuntu下apache2不能解释php程序故障

安装apache2, php5, mysql, phpmyadmin:

sudo apt-get install apache2 libapache2-mod-php5 php5 php5-gd mysql-server php5-mysql phpmyadmin php5-cli php-pear

安装完成后，怎么也不能解析php文件，经过一番查找，解决如下：

microdict@ibm-t60:~$ cd /etc/apache2/mods-enabled/
microdict@ibm-t60:/etc/apache2/mods-enabled$ sudo ln -s ../mods-available/php5.load php5.load
microdict@ibm-t60:/etc/apache2/mods-enabled$ sudo ln -s ../mods-available/php5.conf php5.conf
microdict@ibm-t60:/etc/apache2/mods-enabled$ sudo /etc/init.d/apache2 restart
