So in today's video, I'm going to show you how to check on the status of service is on your Lennox server.

Why Service's are important in the Lenox world and the server world is basically service's are the applications that are running on your server.

So if you have installed a pantry to or engine X or my sequel or whatever else, but the service is not actually running, then when somebody tries to go to your server in order to get a website or to get a database or something like that, they will not be able to access the service.

Kind of sort of think about like if you have a desktop computer and you have installed word on that desktop computer, but you have not opened it up right.

My opening upward now word as a service has started, and you can start interacting with word if word is installed.

So that's basically what we're dealing with in the service is we're World on a Lennox server is a lot of times the reason that you're having a problem with your Lennox server instantly because the service, for whatever reason, has been turned off or disabled.

And so even though it's installed, even though the configuration files have been done and all that kind of stuff, if the service itself is not running, it doesn't matter.

The other reason that understanding how to deal with service is in the Lenox world is important is because if you do any changes to configurations for things such as, let's say, you're your firewall.

So there is a built in firewall and Lennox or, if you do a changes to configuration in Apache or squid or anything else.

Basically, in the Lenox world for configuration, Do you have a text file when you simply go through the text file and you make modifications and edits Well, remember, right?

Those modifications and edits don't actually get loaded into the service until you restart the service.

So one of the problems a lot of new boobs and the Lenox world can have is they go in and they do always beautiful, beautiful modifications to the configuration file.

But then the server keeps doing what it was doing before they get frustrated and they keep going back and back and back, and they keep doing all these strange is that they keep doing all these modifications, and the reason why their server is still working like it did before is because they haven't really started.

The service is if you do, if you change the V hosts within the Apache configuration, but you don't restart the Apache service, then all of that is configurations that you've changed will not be loaded into service.

And so the service will keep doing what it has been doing.

So these are the reasons why service's are very important in Lenox World.

If your service is not running, then again, it's literally and not running.

And if you make changes to configuration files and you do not restart the service, those changes will not be loaded into the servers of the server can perform how you're expected to perform now.

When we start document service's again, you go back to that whole.

Remember, I was talking about that whole good new Lenox saying the cold in new Lenox thing and how Lennox really is only the Colonel and then good new is everything that gets put on top of it.

And then that's one of the reasons why Lennox can turn out to be a mess.

All right, you goto Windows, you're the windows like it or hate it in the Windows world, there's only one way to do things like one way to do things you go to service is any deal.

If you hate the control panel, it doesn't matter if you love the control battle, it doesn't matter.

Microsoft gives you one way to deal with service is Oh, but we're gonna Lennox world with Lennox World.

It's the three ways that basically do the exact same thing as far as service's market, sir.

So even when you're doing simple things like checking the status of service is starting restarting.

Stopping service is there are always multiple ways to do that in Lenox, And one of the reasons why this could be confusing, especially for Nubes, is because you come in and you've learned one way to do things and then somebody else tells you a different way to do it.

And then you get really confused or again, you go to Google.

We're trying to figure out how to do something.

Let's say change configurations and squid or something like that.

And then they tell you how to do something.

And so that's one of the problems with Lennox is it could get very confused because you could literally have it three different ways to the exact same thing s O.

Now, since we're dealing with a bun to Debbie in, uh, they use something called a system buddy.

Now, in order to control service is S o the Let me say this official here, the proper way of a proper way to deal with service is and who want to 18.4 And going forward is something cold.

System D you use a A command cold system.

But understand, even in a bond to 18.4 there's also something called the service command, and so you can actually use something called pseudo service and then Apache two.

Or whatever the service's start Stop restart status, and you basically get the exact same results on for anybody that was doing clinics a little bit ago.

The way that I don't learn to deal with service is is there's also something called I uh innit I and I T V scripts.

So there's a four Call the i n i t dot de folder and in that their specific scripts again for for two deals.

Service's Start stock Restart status, the whole nine yards.

The one thing I will say is that the i n i t.

Basically dedicated means in the Lenox world many times is that it still works.

It's still there, still does what it does, but there is no longer really any updates.

There's no longer work being done on that way of doing things.

And so when they say something is deprecate ID, Basically, what they mean is it's come to the end of the road.

You can still do it But that's not how you're supposed to do it anymore.

Understand, in the bun to world your official where to do it is System D.

If you're going back and you're looking a documentation and again with Lennox right again for dealing squid servers or firewall or Apache, you may go back and you may look at some documentation from, Let's say, 2012 within 2012.

I I and I T D scripts where the way to do things and so you may see something where they say, modify the configuration files and such and such way.

And then this is how you restart the service.

And so one of reasons I'm showing you that is just to show you that again, at least in 18.4 It's still work that it probably still work well for work for a few more years.

So I'm just showing you that to show you that it exists, and if nothing else is, you get it.

When you do see it in the future, you go.

So instead of using i n i t d I'm gonna use a system de loop roper where to do it instead.

So do you remember in the Lenox World one of the reasons why Lennox could be so Dorn fusing is you literally you literally three ways.

Three ways to to something s eval as start, stop, restart and status on service is so with that, let's go over to my computer.

I guess you're the exciting world of service is, uh so here we are my Avanti server again, we have running a bunch of 18.4 point three.

Lt s But everything that I'm showing you today should should work for about a decade into the future.

There should not be any differences and many of the things that I'm showing you can work 10 generations in the past three.

Only thing that might not work if you have an older version of Lennox, is the whole system.

The thing I think System D came in four or five years ago.

So it should work on any relatively new versions of a bun too.

But I don't know if you had a distribution from, let's say, 2010.

But on the other hand, why the hell are you running a distribution from 2000 type video?

So again, it's the athletics world that's out, Goes S O.

This is the standard of standard server insulation with virtual box.

The one thing that I have done is I haven't sold a patchy too.

So Apache to is a Web server service, I guess so that we have a service that we can interact with here as I'm gonna log in.

123456 If that's how I roll with security and gonna hit Enter.

So we're now long dead and I'm going to do clear and order to clear the scream s So we're gonna deal with system.

The first AM tbe clue system D is the proper way.

The proper way to deal with service is in the Lenox world.

So the other things that I'll show you today our ways will end up doing the exact same thing.

When the problem proper, Robert way system deep.

The first thing that we d'oh with system deep is we can use the system C t l command for status.

So to look at the status of the different service is on the system.

So we knew pseudo system c t l and then space status.
