Basic questions about One-Click Install WordPress on Ubuntu 12.10

Hi,

I am new to Digitalocean and VPS hosting.

I am learning to setup and move data for my WordPress blog. I use both methods - first, setting up WordPress from starch ( I followed this tutorial - https://www.digitalocean.com/community/articles/how-to-install-wordpress-on-ubuntu-12-04). Second, using one-click install (I am following this tutorial- https://www.digitalocean.com/community/articles/one-click-install-wordpress-on-ubuntu-12-10-with-digitalocean) . The first method- setting WordPress from scratch, works perfectly well, but I am having trouble in one-click installation.

First Question: When I use one-click to feature install WordPress on Ubuntu 12.10, it simply install WordPress, and left me unaware about details such as MySQL Database name, username and password for my newly installed WordPress blog. I also tried to access wp-config.php. file, but I was baffled after seeing that there no information was stored in the file-(https://dl.dropboxusercontent.com/u/13241857/wpconfig.PNG). Can you help me find these details ?

Second Question: I am also trying to install PHPMyAdmin for database administration and importing old database. I used apt-get install -y phpmyadmin, and I can easily access PHPMyAdmin login page by navigating to http://IP/phpmyadmin ( https://dl.dropboxusercontent.com/u/13241857/phpmyadmin.PNG). But I don’t have any idea about the login username and password. Where can I find these details ?

Third Question (not much important): When I execute mysql, sometimes, I encountered this error message- ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: Yes). What cause this error message ? Any idea ?

Note: Software I use - DigitalOcean Console, Putty and WinSCP.

Your help is appreciated.

Thanks Ishank
