Skin color is an illusion from Nina Jablonski

This talk is kind of special. The content has nothing really new to me, except the fact that Darwin had actually concluded that skin color has nothing to do with climate. However, Ms. Nina Jablonski delivered it in such passion and power that you feel the urge of immediate action.

You can tell from the fluent flow of long sentences that this is for sure a carefully prepared talk. But no passion was lost in the preparation. Outstanding!

setting up OTRS 4

I was asked to evaluate some ticket tracking tools and OTRS came back into my mind. The following steps outline the procedure to have OTRS correctly installed on CentOS 7:

  1. LAMP stack; You probably already have it. And on your system you might have MariaDB instead of MySQL. That doesn’t matter.
  2. Install and configure Postfix and Dovecot.
  3. Make sure the following configuration for MySQL has been taken care of, especially for the 3rd line: 
            max_allowed_packet=50M
        query_cache_size=32M
        innodb_log_file_size=1073741824
  4. Install some additional perl modules from EPEL repository.
  5. Install OTRS from command line: 
    yum install --nogpgcheck http://ftp.otrs.org/pub/otrs//RPMS/rhel/7/otrs-4.0.11-01.noarch.rpm
  6. Once the installation is done, continue with the web installer from: 
    http://<your host ip>/otrs/installer.pl
  7. Simply following the wizard and then you should have a working OTRS installation.
  8. Login to OTRS using super admin account. Go to “Admin->System Administration->Package Manager” and install additional packages. Typically you’d want have OTRS:ITSM and other related packages.

Up to here, you have a working installation. In order to work with OTRS, now you have to configure all the queues, agents, customers, groups, templetes, etc. Have fun!
