That should be it. Don't forget to create a user account right away.
If you want, this should be able to be run as a script.

That's because that's the old guide. I have a more recent one that works great. Rocket.Chat is available from snaps and is self maintaining.

Google failed me this afternoon then, doh!

While Rocketchat may be available in a snapd package, snapd itself is not a native part of RHEL 7, CentOS 7, or Fedora 25.

For CentOS 7, snapd is not available from yum

For Fedora 25, it is in the built in updates repository and can be installed with dnf install snapd

But none of this negates the fact that, yes your previous instructions are broken. Nor does any of that negate his instructions here.

Even better.... @scottalanmiller, it is flat not supported on CentOS 7.

That's why we switched to running it on Ubuntu with Snaps. Runs great.
