Here is the magic

purge binary logs to 'mysql-bin.****';

* is the name of latest binary log file.

This is safe and quick, and can get more free space.

Just open wp-config.php, add the following line

define( "WP_POST_REVISIONS", false );

Once PHP is installed, but new extention is required, it is always recommended to run the following, take ldap for example,

cd ext/
cd ldap/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install

then all is done.
