Can't install UFW on Amazon Linux server

Question

I'm trying to install UFW on my amazon linux server with yum and here's what I'm getting:

[root@ip-XXX-31-43-YYY ~]# sudo yum install ufw
Failed to set locale, defaulting to C
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package ufw available.
Error: Nothing to do
[root@ip-XXX-31-43-YYY ~]# 

What am I doing wrong?

I can't install via apt-get.

Answer 1

There is no ufw package for Yum.

Lighten the load on your server, and don't install a firewall on it. Instead, control which ports are open in an AWS Security Group.

Answer 2

Here is the easiest way to install ufw in Amazon Linux 2.

Install UFW on Amazon Linux 2

Step 1. Update Amazon Linux 2 system packages.

Step 2. Install and enable epel repository on Amazon Linux 2.

sudo amazon-linux-extras install epel

Step 3. Now, install UFW.

yum install --enablerepo=epel ufw

Step 4. To check the version and installation as well, run:

ufw --version
