Re: Connect to MySQL database (on Ubuntu Server) using Perl

[moritz]

Supply a hostname to the connect call (localhost if the database server is on the same machine), so that mysql connects through the network.

Also I think you have to write "dbi:mysql:database=$db".

See DBD::mysql for more information.

Hi,

Thanks for the reply. I've changed my code to this:

#!/usr/bin/perl
use strict;
use warnings;
use DBI;

my $username='username';
my $pass='password';
my $db='database_name';
my $host='hostname';
my $dbh = DBI->connect( "dbi:mysql:database=$db:$host", $username, $pa
+ss, { 'PrintError' => 1, 'RaiseError' => 1 } );

I'm still getting an error: Unknown MySQL server host 'hostname' (2) at ...

Use the real host name, not "hostname". For example "localhost". The documentation of your VPS should tell you what the correct hostname is.

I just used hostname for my privacy. I used the real hostname in my script.

When I was setting up my server (for my first time) I gave it a hostname (that's the name I tried in my script). I haven't done all the dns stuff yet. I've tested the site just using the ip address (I've also tested this as my hostname).
