Well you could install CentOS and search around some basic administrative tasks to learn. If you want to learn anything on Linux, I would recommend at least gaining an understanding of the command ... [by usr_drc]
I have been using Ubuntu 14.04 LTS server for a few months now, and although I'm still trying to figure out this server system, I'm also looking to setup and learn how to use a CentOS 7 server as well. I realize that there is a learning curve between an RPM system and a Debian system, but I can't seem to find ANY learning material on how to learn CentOS 7.
Hi all and TIA for all the questions I will have. I am just over the 'noob hill' trying valiantly to learn Linux. Luckily, I landed a job where I do basic Linux administration on HP-UX, but it is very basic and it is a live system. Which means I cannot play or learn as much as I would like to.
My background is biology and not experienced at all with anything related to coding or programming, but just beginning. I have recently partitioned my old pc (with windows Vista) and installed CentOS Linux 7. I am trying to learn Linux. For a beginner, I have a problem and a question.
Problem: I cannot get windows anymore on the computer.
So I want to learn about Linux more and to an extent Red hat, and I think the asking price ($49p/a) is a decent price to learn, I don't want centos because I would prefer Red Hat software, but is it worth having?
I of course plan to get a RHCE at some point so would it be worth investing now so I can learn the distro?
I'm having trouble understanding why CentOS is using ~1.5g for disk caching, even though it's using ~2g of swap. My understanding is that Linux will use part of RAM for disk caching only when it's not being used for something else.
I have set vm.swappiness down to 10 (default was 60), with no effect (using sysctl -w).
