Today I finished part 1 of the Elasticsearch tutorial. It explains (in german) how to set up CentOS minimal for the ELK server. This is to do in advance. Next week I will publish part 2 which will include the installation of Elasticsearch. I know that the website is not optimized at the moment and some content doesn't look good. I have decided to put some content online related to some e-mails i have recieved about the tutorial.
