I wouldn't mind seeing a good guide for ELK. I've thought about setting one up, but never had the resoures in my home lab until recently.

That's the one I used.

If you want to cheat, they have a one click installer

Definitely no need to build your own from scratch. They have they prebuilt for you.

I tried to Spin it up on CentOS7 at home last night... I got it almost working, but I'm still missing something aparently...

Where's that one-click installer at? I didn't see it anywhere...

scottalanmiller

When you go to build a new machine on Digital Ocean, you select ELK as the VM type.

scottalanmiller

Here you go...

Calling it a "one click installer" is very confusing. It's nothing like that. It's a pre-built image.

dafyre

@scottalanmiller Ah, this would be my problem... I'm trying to build it myself, lol. Once I can deploy it by hand, then I'd look at a DO droplet or the like.

Learn it the hard way first, that way when you break it from the one-click-installer, you can at least go digging to figure out why it broke.

dafyre

So I got my own ELK stack installed in my meager office lab... It wasn't too teribly bad... I enjoy using the most recent packages when I (attempt) to build something, so I used the latest & greatest betas out for Logstash and Elastic. A few quick googles and I was good. 8-)

Now to replicate this on my home server which arguably sees more traffic than my office test setup, lol.

ELK is definitely the way to go. So powerful!

dafyre

That DO article left out some steps about allowing Firewall rules for some of the ports, I think. I've bee na few days since I've looked at it... I have noticed that I need to set the Kiban4 and logstash processes to restart once a day or the whole thing stops.

I'm stuck in here :

create and edit a new yum repository file for Elasticsearch:

sudo vi /etc/yum.repos.d/elasticsearch.repo

Add the following repository configuration:
/etc/yum.repos.d/elasticsearch.repo

**** [elasticsearch-1.4]
name=Elasticsearch repository for 1.4.x packages
baseurl=http://packages.elasticsearch.org/elasticsearch/1.4/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1****

You should post in a new thread as this is a fresh question.

Thanks.

I really like the Digital Ocean tutorial series they did a while ago, like installing MediaWiki. Creating something which you can use at home also helps make projects like these a bit more personal - and thus interesting. Build your own media server (samba, ftp or a bit more advanced like ownCloud). Just make sure it stays a challenge: buy some Raspberry Pi's or Zero's and cluster a web app with MySQL, Redis and stuff like that...
