How to install Docker on Ubuntu 18.04

February 25, 2019 By Albert Valbuena

Operating System level virtualization is hitting hard now, as much as VM’s did just a few years ago. Docker is the popular framework for this matter, the new kid on the block so to speak. This is the hot spot now and if anyone wants to appear knowledgeable about system administration knowing this technology is […]

How to improve Apache HTTP performance on FreeBSD

February 17, 2020 By Albert Valbuena

There are some nice articles on the internet telling you how to improve your Apache HTTP server’s performance. I did my bit on FreeBSD land.

How to set the locale in FreeBSD

April 25, 2017 By Albert Valbuena

The locale is the character set that will be used. And it is very important to match the keyboard you are using. Mind this also matters if you are transferring data to other systems. Different standards as the ASCII, UTF’s and the ISO’s, to name a few, have been put in place through the years […]

How to install the bash shell on FreeBSD

January 28, 2019 By Albert Valbuena

Believe it or not the Bash shell does not come installed on the system. By default FreeBSD uses the sh shell (after the rewrite under the BSD license on 1989 of the original Bourne Shell found on UNIX, which had inherited the ‘sh’ name from the original’s Thomson shell), the C shell or the tcsh […]

How to install Nagios on FreeBSD

January 8, 2018 By Albert Valbuena

As explained in an introduction article, Nagios is a monitoring software very well established and used in production on many environments. Results are displayed in a web page so it uses a web server to publish them to the user and needs some php code to do so. It is configured through files which happen […]

How to install the ELK stack on CentOS 8

April 30, 2020 By Albert Valbuena

The ELK stack stands for Elasticsearch, Logstash and Kibana. These three pieces of software are very useful since each brings a powerful capability that in combination is just great to use. Elasticsearch is a search and analytics engine. Logstash can process data from multiple sources. Kibana allows to visualize data in a graphic manner. These […]
