 * I have a domain that already has a WordPress blog installation in a directory.
 * I am changing the site to wordpress and I would like to keep the old blog as 
   it is.
 * I opened a new MySql database and edited the wp-config.php file accordingly.
 * This is the message that displays when I go to run install.php
 * >  Error establishing a database connection
   > This either means that the username and password information in your wp-config.
   > php file is incorrect or we can’t contact the database server at MYSQLHOST.
   > This could mean your host’s database server is down.
   >  * Are you sure you have the correct username and password?
   >  * Are you sure
   > that you have typed the correct hostname? * Are you sure that the database 
   > server is running?
 * I checked a few times to make sure that the database name, username and password
   are correct. They are.
 * I created a new database for this blog, but maybe having it on the same domain
   as another blog is causing an error?
 * > from wp-config.php –
   >  // You can have multiple installations in one database
   > if you give each a unique prefix $table_prefix = ‘wp_’; // Only numbers, letters,
   > and underscores please!
 * Do I need to give it a table prefix?
 * I thought that making a new database & new user would clear all that up…
    yet
   still there is an error establishing a database connection 🙁 Please Help!

 * _This either means that the username and password information in your wp-config.
   php file is incorrect or we can’t contact the database server at **MYSQLHOST.**_
 * Is your database on a computer called **MYSQLHOST** if not and it’s on the same
   server as the webserver then that needs to be changed back to localhost.

 * I first tried it with localhost and after that didn’t work, I reexamined my MySql
   database info and saw that it says
    Host: MYSQLHOST
 * Needless to say, that didn’t work either…
 * and for the record, I also re-copy/pasted my database name, username & password
   to make sure that there wasn’t a typo or extra space or anything. Still showing
   error in connecting.
