Cant connect to database

I am new to asterisk freepbx. I also have some knowledge of linux so here goes

I installed Fedora Core and installed asterisk 1.8 I am following a guide on http://www.voiptoday.org/index.php?option=com_content&view=article&id=110:freepbx-how-to-install-asterisk-freepbx-on-centos

Everything went ok until i ran this command
./install_amp --username=asteriskuser --password=SOMEPASSWORD

everything says OK except connecting to database …Failed
[Fatal} Cannot connect to database

can someone tell me how to delete the db and recreate it or is there an easy fix for this .

When it says ‘SOMEPASSWORD’ it means that you should provide a password of your own (without the single quote characters). Now you have provided a password that contains the single quote character

'SOMEPASSWORD'

That wont work. As for how to delete and re-create the database, Google is your friend.

But, since you have limited knowledge of Linux I can see other parts that could fail, I suggest that you download our Distro instead.
You will find it here:
