MySQL & PostgreSQL

To create a database and account for yourself on vulcan, first run `vulcan_create_db`, then run `vulcan_reset_db_password` to activate your accounts and set up a password for your MySQL and PostgreSQL databases. If you're doing web development, please use a unique password for your databases (one that you don't use elsewhere).

phpMyAdmin and phpPgAdmin are installed for general database access. If you want a desktop client (MySQL Query Browser / PG Admin), you can use PuTTY's port forwarding feature to connect securely.

This will set up PuTTY to your local port to vulcan's MySQL database. Set your client to connect to '127.0.0.1' port '3306'. The same can be achieved for PostgreSQL by changing the ports to '5432'.

Publishing Web Content

• Put the web content you want to publish in the public_html directory in your account.
• To access, go to: http://vulcan.ist.unomaha.edu/~username/
• You can create an 'index.html' file to display instead of the directory listings.
• Run `vulcan_publish_website` to set up your public_html permissions correctly. By default, vulcan will use very restrictive permissions to prevent others from reading your data. Unfortunately, this means apache can't see your public_html files, `vulcan_publish_website` will fix that.
• You can see your portion of apache's error log, and access log via ~/.http_error_log and ~/.http_access_log. These files are rotated nightly, so copy them if you want to keep them. You can use `tail -f ~/.http_*_log` to watch them in real time. Note that the daemon that does this tries very hard, but isn't quite perfect, so some errors might be lost
• See what vulcan's install of PHP has to offer.
