Getting the EPEL and Fail2Ban on CentOS 7

[thanksajdotcom]

I'm not familiar with what EPEL is. I've seen the term before but never researched it. What is it exactly?

EPEL

Extra Packages for Enterprise Linux. CentOS was once a offshoot/fork of Redhat (not sure if it was officially or not)

EPEL is the Extra Packages for Enterprise Linux. It is basically a subset of the Fedora ecosystem that the community maintains for RHEL. The official repos for RHEL are rather limited (no Fail2Ban, no htop, very few dev packages, etc.) The EPEL gives you heavily tested packages, but not with full official support. But RH oversees the EPEL.

If you have a large RH contract, you can get things in the EPEL to be supported if you need it. I've done that before.

It's not from the CentOS project, it's from Fedora. EPEL was officially part of Red Hat always. CentOS is only a recent addition to the RH family.

You'll need to enable fail2ban too...

systemctl enable fail2ban

Ah, thank you. I know I could Google it, but an explanation from one person to another is sometimes just nicer. That and I know you guys don't mind answering, and then it's here for the next guy to find too!

I always install sysstat so that I get SAR reports. SAR collections starts automatically once installed.

yum -y install sysstat

What is that and how do I view the reports?

I also like htop. Pretty minor, but it is a nice utility.

yum -y install htop

What is that? I can't find anything conclusive that tells me what it is

@nadnerB a process viewer similar to top.

It's an "enhanced" top command.
