OpenNMS
-
I'll admit - not done much command line tasks in a very long time. And only a bit of Linux. But with having a EdgeMax Router Lite, and a CloudatCost DevBox - it's high time I really put some time in learning.
First project is openNMS - Open Source Network Monitoring System.
I'm following their documentation for installing it and have to say - not having to much issue thus far.

Way to go!

I've been working on this for a little bit now,..
- Installed the Repository RPM
- Installed the PostgreSQL
- Installed Nano to edit the pg_hba.conf file to allow access to the db.
- restarted the PosgreSQL db
Didn't want to fight the Java 7 JDK - the document stated that they "While we provide a JDK in our YUM repository as a fallback" so this one step I have skipped.
Now I get in to a spot, Installing OpenNMS.

Is the GPG key causing this? Is my skipping installing the Java7 package to 'blame'?

Make sure you run Yum update and then do
rpm --import http://yum.opennms.org/OPENNMS-GPG-KEYto reimport the key. -
Learn vi.

Yeah, what's up with installing nano?
My thoughts exactly.

didn't run when I attempted to use it. Nor was emac
[root@localhost data]# nano pg_hba.conf -bash: nano: command not found [root@localhost data]# emac pg_hba.conf -bash: emac: command not found -
I'm assuming vi works no problem though.

Easily said - what is vi?
And yes,.. I am looking for it.
vi is the one text editor that exists in "every" UNIX system. It's the editor you always have, no matter what. Only one you need to know because it is the only one you know you'll always have.

Vi is a text editor, sometimes also called vim. It'd just be:
vi pg_hba.confPress i to make edits and when done, press Esc and :wq followed by enter.

I see.. now. Been around since 1991 pronounced vee-eye

@thanksajdotcom
Thank you. -
It's slow - but It's running, and I'm connected.
-
Most any network monitor will be slow, without beefy hardware to back it up. They are quiet resource intensive.
-
It's on CloudatCost -

Nothing wrong with using nano either. I have never had an issue caused by nano.
I know how to use vi, but I don't use it.

(command line) restarted the box yesterday.

That's where the log stops?
