i installed xdebugger based on the customized installation instruction at http://xdebug.org/wizard.php

I use xdegger help chrome extension to enable debugging. I tried jetbrain's bookmarklet too.

/etc/php.ini settings:
xdebug.remote_enable=On
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"
xdebug.remote_mode=req
xdebug.remote_autostart=On
xdebug.idekey=PHPSTORM
xdebug.remote_log=/var/www/xdebug.remote.log
xdebug.profiler_output_dir = "/tmp/xdebug/"
xdebug.profiler_enable = Off
zend_extension = /usr/lib64/php/modules/xdebug.so

I tried port 10000 and it didnt work either.
