Hello, everyone, redhead eight, the newer version is out already, and I'm sure that you guys are
aware and you already know CentOS is the same as RedHat, so I've decided to create this video.
So you understand what exactly the difference between seven and eight.
So Readhead Enterprise Lennix eight, which is also called in short, Relet is now available for production
use with lots of lot of developer friendly capabilities relaid official release by RedHat was announced
on May 7th, 2019.
So I'm going to cover only what has changed and what you should know in terms of my course.
So let's go over it one by one.
So on the left hand side, we're going to talk about what other things that have changed.
And the other two columns, four, eight and seven, saying general availability ET became available
for the development use on November eight.
Fourteen, twenty, eighteen.
And for seven it was 2014.
So code name for seven we had Maypo and four eight.
It's called ARTPOP.
Kernel version four seven is three point one four eight.
It's four dot eighteen.
End of support for eight right now.
They have it for May 2029, whereas seven we still have the support until 2024.
Last minor release for REL Aid.
It's just started.
So there isn't any maybe by the time you are looking or watching, this video already has a minor version
out, whereas a relatively minor version was seven seven.
All right.
Network time synchronization.
So you probably know and right.
So rels seven has A.P. as well as Cronie D, which is a chronic demon to these are two different services
that were introduced and seven now in eight.
It's only Karani.
Just remember that you won't be able to work with A.P. or A.P. configurations.
GUI interface.
There is a newer version for Genom, the default database RÉAL seven only had or supported Morea DB
or database, whereas the newer version has a lot of other support for other databases as well.
For example, postgrads radius.
All right, moving on, the default firewall Inwell eight, which is Firewall D, it uses an tables
framework in the backend in seven firewall D, it used IP tables framework in the backend.
So if you remember the IP table, then you want to stop and stop, start the service.
You would do IP tables, but he was still it was still tied to firewalled.
But in eight you would have to start install firewall D which uses the Ancef tables are Máximo support,
individual file and filesystem size.
In seven you have only up until five hundred terabyte.
And of course it was on Zayat FS and it was a Zephyrs was introduced in seven, now in eight again by
default.
It's still Excel file system and now we have a file system support up up to one terabyte.
So one zero sorry one petabyte.
So one zero two four terabyte package management by default both are installed youm so seven has a youm.
If you remember you would use a Jum and DNF can be installed from extra REPL in seven.
You could still use DNF, but you probably don't know what DNF is if you're using seven but an eight,
something you need to keep in mind if you have install eight by default.
Both our install youm is symbolic link to DNF so you could still run youm, but it is linked to another
command call DNF most likely in REL.
They're probably going to completely deprecate youm and they're going to start using DNF.
But anyway, good news is that the game is still available.
DNF is the newer version, which is available in eight as well.
Maximum RAM support for seven.
We had it twelve terabyte on 64 architecture system and now in eight we could have up to twenty four
terabyte Onex.
Sixty four architecture as well.
So in summary, as you could see, there is in any of the differences that probably that you thinking
that could affect any of the contents that I have in my course.
Eddie, everything that I have covered in my course, whether you go with S.O.S eight or seven, everything
that I code, it's still well, it is still applicable.
All the commands that you've learned, nothing changed.
So if you have additional question, if you want to know more, there are a few more changes which.
Has nothing to do with what I have covered my course, but again, if you wanted to know more, I have
actually also added some documentation and handouts where you can look and you could find out all the
details about both the differences between both seven and eight.
All right.
Good luck.
