Technology Errors

mysql: grant all privileges on test.* to ‘root’@’localhost’ identified by ‘s3kr1t’

The below is part of the output when receiving an error attempting to install the Perl DBD::mysql module using the CPAN shell. I rarely use the Perl CPAN shell since most of the packages are available on CentOS, my typical Linux distribution choice for servers, using the yum package manager. In this case I was working on installing Monarch on a server at work to assist with Nagios file management. Monarch allows you to backup the entire Nagios configuration files with the click of a button. Monarch will also provide a visual view of any Nagios build errors, Nagios configuration files (including users, user groups, services, check commands, etc.,), and more. So when attempting to build the Perl DBD:mysql module via the CPAN shell I received some errors which I initially did not understand because they did not explain the specific issue however I eventually located the problem which ended up being easy to resolve. Below I describe the error in detail as well as information on how to resolve.

Perl Module Error: Can’t locate URI/ in @INC

In the process of installing Monarch, which is a Nagios file manager, earlier I ran into a couple errors for modules I thought I had already installed. Then I realized the issue must be because during the process of installing modules Perl wanted to upgrade from 5.8 to 5.10 on CentOS. I went ahead and upgraded Perl however I left 5.8.8 intact since CentOS seems to rely on Perl 5.8.8 in many ways. Anyhow the full error I received is below as noted from the Apache error logs. You can easily resolve the below error by following the directions below.

MySQL Ruby Gem: `require’: no such file to load — mysql (LoadError)

I am starting to learn ruby and am working on a test script to import some data into a MySQL database. I am using the below code found on to first get the MySQL connection from Ruby working. The code was producing an error which I figured might be because I installed the MySQL Ruby gem instead of installing the MySQL Ruby module from source.

The below code attempts to connect to the MySQL server to return the MySQL server version.
