Where should I leave?

When I write the command to change the pass tells me this:
mysqladmin: Can't turn off logging; error: 'Access denied; you need the SUPER privilege for this operation'

I usually use debian ubuntu and when I have # root on centos I directly # qando by then I thought to be already root or we must give sudo su to become root

I am following this link http://josephades1.googlepages.com/gen_securetb change mysql pass as written but I can not find the file and the "dbpass" line in / etc / asterisk / res_mysql.conf and if I try to enter into setting pbx I wrote FATAL ERROR
DB Error: connect failed HELP HELP Please :|

I haven't installed 2.6.1, but you could always grant the user superuser access then just modify it in mysql directly.

The above link wasn't working for me with a clean install of 2.6.1, however, after speaking with Kerry G, I have the solution:
asteriskuser mysql password:

(from the Linux CLI):

mysql -u root -p
(enter mysql root password, default is passw0rd (with a zero))
mysql> use mysql;
mysql> update user set password=PASSWORD("new_pass_here") where User='asteriskuser';
mysql> flush privileges;
mysql> quit

Now change to the new password in these files:

/etc/amportal.conf (AMPDBPASS towards the bottom of the file)
/etc/asterisk/cdr_mysql.conf (password field)
Once done, run these commands from the Linux CLI:

service mysqld restart
amportal restart

That should do it. To change the mysql root password, the old way still seemed to work.

mysqladmin -u root -p password new_pass_here
(prompted for old mysql root password - default is 'passw0rd' - no quotes, with a zero)

Now change the password in this file:

/etc/asterisk/cbmysql.conf (password field)

Thanks Kerry for the info!
