    Hello. I am new with WordPress. I use Azure to create an Ubuntu virtual machine with MySQL, and other Azure instance with an empty web to install WordPress by FTP.

    I gave the appropriate permissions to the user, the MySQL user is up; but when I try to install WordPress, navigator returns:

    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 prueba-ubuntu-server.cloudapp.net:3306. 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?

    If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

    How can I fix it?

    In nutshell, you’re getting this error because WP is unable to establish a database connection. Reason why WP is unable to establish a database connection can vary. It could be that your database login credentials are wrong or have been changed. It could be that your database server is unresponsive. It could be that your database has been corrupted. Majority of the times this error happens because of some sort of server error. Also, there could be other factors as well. To troubleshooting this problem:
    – double check your wp-config.php file settings for the database name, database username and database password, and the host name (e.g., “localhost” Vs. something else). This is where most errors occur. – Then make sure wp-config.php is in right location.
    – Then check that you don’t need to change the database host from “localhost” to something else. You can get that info from your hosting provider.
    – Check you have actually created a database with the same database name as is in your wp-config.php file.
    – Last, but not least, if all that information is correct your database probably has a problem with it. Contact your hosting provider if the database server is offline (if the problem suddenly happened), or if they have any other problem at their end, or they made any changes to your account, or if there are any limitations/restrictions, or if the hosting package is set to Windows and not Linux, etc.
    – If the error is intermittent then it’s your server. What’s happening is that the web server and/or the database server are gettign overloaded and the connection is droping out or is refused for a short time. That gives you the database error as the website can’t connect to the database. To fix this, you’ll need to talk to your hosting company as they are the only ones that can do anything about hardware issues like this.
