# Installation – DB Connect Error

 * I have installed three wordpress instances, three are working, one is not.
 * The three working are named:
    asparagazette linksoftheweek niuviewpoints
 * The one that is not working:
    friendsofniuview
 * I have one wordpressuser account for all instances (wordpressuser) and I created
   a db (via mysql) that is the same name as the wordpress instance.
 * This is the error:
    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 locahost. This
   could mean your host’s database server is down.
 * I dbl checked and everything is named appropriately:
 * define(‘DB_NAME’, ‘friendsofniuview’);
    define(‘DB_USER’, ‘wordpressuser’); define(‘
   DB_PASSWORD’, ‘xxxxxxxxx’); define(‘DB_HOST’, ‘locahost’);
 * Is there a naming length limitation?
 * Thanks in advance for your help!
 * ~George

 * As long as each wordpress blog has a different $table_prefix in wp-config.php
   you could install hundreds of blogs using the same database, user, password.
 * If the database is already created with the user granted the proper privileges,
   length of the name should not be the issue.
 * Maybe the database server is actually down!

 * The db server is up. The other three blogs work fine. The only issue is getting
   this fourth one up. Each has their own db, but I went ahead and modified $table_prefix
   but still the same:
    the other three work fine, I cannot get this fourth one 
   to work…

 * If you’ve used a different $table_prefix you should be getting ‘thrown’ into 
   a new installation process.
 * So the database server specified in DB_HOST is running, and you’ve confirmed 
   nothing is wrong with the DB_USER and DB_PASSWORD by using [phpMyAdmin](http://codex.wordpress.org/phpMyAdmin)
   to access your database(s).
 * Did you confirm the database privileges for your DB_USER?
