I am almost finished building my ELK server which i found exiting to do. I have pushed already 12 logs to my ELK server and have almost 5GB of indexes. All runs fine and i am now exploring how to proper use this neat tool so i can convince my old server administrator to use my ELK server instead of his old grep text based server he ever build (which works fine also).
So i found a webinar movie on this website and when i was following it, he mentioned a few times to keep ELK up to date. And not only that, also Java version. So, of course, i checked my Java version and found out i have 1.7.0_91 which is not recommended.
Also he mentioned to update Elasticsearch on a regular basis. But here comes the part....how do i safely update my ELK incl. Java?
I installed all packages trough RPM (when possible) and not trough a repository. So, to be honest, i am afraid i will break things if i try to update my packages.
Is there any convenient way to keep my server up to date without breaking things?
