etch amd64安装php5后没有php.ini问题

[cnhnln cnhnln]

etch amd64
aptitude install apache2 mysql-server php5 libapache2-mod-php5 php5-mysql
php5-mysqli phpmyadmin
以后发现/etc/php5/apache2和/etc/php5/cli下都没有php.ini
搜索php.ini以后发现有如下文件
/usr/share/doc/php5-common/examples/php.ini-dist
/usr/share/doc/php5-common/examples/php.ini-paranoid
/usr/share/doc/php5-common/examples/php.ini-recommended
/usr/share/php5/php.ini-dist
/usr/share/php5/php.ini-dist.cli
求助分别该使用哪个文件？谢谢
