Can not connect to MySQL with CodeIgniter. Possible DNS issue? - mysql

Question

I am running a dev LAMP with Codeigniter. However, when I try to load the page, the database can not connect(the database is actually on another server) and I get this error:
A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 346
My database.php is this:
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'myhost.com';
$db['default']['username'] = 'myusername';
$db['default']['password'] = 'mypassword';
$db['default']['database'] = 'mytable';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
If I change the 'pconnect' and/or 'db_debug' to false, I get the same error or it just doesn't work. I know the database is up and running correctly because others are able to connect and use it.
However, if I put the IP address of the host into the database.php file, it works.
I tried flushing the DNS and even changed to Google's DNS servers to no avail.
The result of a simple mysql_connect is:
A PHP Error was encountered
Severity: Warning
Message: mysql_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known
Filename: config/database.php
Line Number: 67

Answer 1

Try change this
$db['default']['db_debug'] = TRUE;
to this:
$db['default']['db_debug'] = FALSE;

Answer 2

Ensure that the domain name is registered to the correct I.P. address and your host has the record of this exact address. Try placing a static HTML file on the website, all you need is something that displays maybe the text "Hello World" to ensure that you are able to access the website via the domain name.
Ensure that you have inserted the domain name correctly in the script and that you can log in to PHPMyAdmin (or whatever you use) with the required credentials via copy and paste (without leading and trailing whitespace, be careful of that).
If it is a problem with the table name, it should say so. As for the rest of the settings, I am not familiar with any of them, but what I have outlined here should see your database working.
Good luck.
