Nothing affected the server in anyway, however.

You need to modify your mirrors, in the yum.conf. That mirror is obviously bad from the error.

Where is yum.conf stored?

It is stored in /etc

I can just find a working mirror from CentOS to replace this?

http://centos.org/modules/tinycontent/index.php?id=13

you pick a mirror, you put it there, umm boom it works. self explains itself.

Yeah...it did work.

HOWEVER, cPanel is still displaying the kernel as 2.4.21-20.0.1.EL.i686, even though I installed the latest version.

Is there a reason for this?

You must reboot into the new kernel

I did run a reboot...is a special process needed for kernel rebooting?

then you need to modify your bootloader (grub/lilo) so it knows the default kernel.

That's what is shown in the lilo file.

cPanel displays 2.4.21-20.EL.c0smp

Umm you should really learn to research this stuff yourself. Its very basic administration skills

change

default=2.4.28

to

default=2.4.21-27.0.1.1

then save it and run

lilo -v -v
reboot

Thank you,
Steve

A google search on "how to upgrade kernel with yum+cpanel" doesn't yield me results. There's no way I could know this without asking.

Thanks.

And, that's not the end of the issues.

Upon doing this, my cPanel "broke" - it's not recognizing my license.

No but searching on lilo would have got you the answer.

/usr/local/cpanel/cpkeyclt

Disable any firewall you have running. A misconfigured firewall WILL BREAK CPANEL.

Nothing was misconfigured, this issue only happened after following the upgrade advice listed here.

But, will disabling the firewall work?

No, that didn't work. php is not working on one of my servers and i still can't access cPanel.

Just try what i said, including disabling firewall. If it dont work, then go to verify.cpanel.net and check if you still have a valid license.

Also how do you know its not misconfigured??

Yes, verify.cpanel.net said it's active.

And, that did not work.

I know it's not misconfigured because after several months of being turned ON, I have never run into a problem like this.

PHP includes don't appear to be working on one site.

cPanel isn't working totally

And, some sites aren't even loading.

kernel upgrades will not cause any of those problems.

Let me detail the process I did:

yum update
shutdown - r

(everything's working, but cPanel doesn't display newest kernel)

You said to change the default in lilo. I did.

Then I disable firewall, run lilo - v - v
reboot

Problems.

cPanel = invalid license error, even though my IP is registered.
php on ONE site isn't working
BOX isn't loading some sites.

===

You obviously are experienced, but don't try "it wasn't me" - I followed everything as suggested here.

CISupport,

None of those issues can come from a kernel upgrade. I am done with this thread as you are apparently trying to blame this on me. You my friend need to learn to manage a server.

WELL, DISPLAY WHAT IN THE PROCESS COULD'VE CAUSED THEM, BECAUSE BEFORE I OPENED THIS THREAD, NOTHING WAS WRONG.

I'm losing revenue due to following the steps in this process. I'm not blaming anyone, but especially not myself, since I followed the advice of experts.


==

yum update (updates kernel and os files)
(update successful)

Everything's running smoothly, except cPanel is not displaying right kernel

Edit: lilo.conf

lilo - v - v
reboot

(something's wrong)

per advice, service apf stop
lilo - v - v
reboot

(something's still wrong)

Why not just roll back the kernel? Google for it. Im done here. I dont like being blamed for something that could not happen from the process.

Alright, I ran into an issue running "yum update" and as you can see, the thread was answered below:

http://www.webhostingtalk.com/showthread.php?s=&threadid=357359

I don't profess to be a server expert, which is why I followed the advice above.

However, never has anything like this happened. I don't even think this is covered by support, so I'm going to end up being out tons of money and don't know what to do.

I understand Steve's reputation here is better than mine, but the facts are as follows:

I took his advice
Server got f'd up
He won't help.

OH yeah bro... Did you ever think that yum update can update files that need to be not updated? That i did not tell you to run. You ran that on your own.

Yum update can install php httpd rpms that will not work with cpanel.

Why dont/didnt you hire a server admin for $50 or less?

Steve is one of those "admins" and I see the type of service he is providing.

With his advice, I ran into a problem.

With my own, I did not.

I need help. I may go to a server admin later on, but for now, someone please help me. I'm BEGGING.

This whole thread is about yum... I believe you said yum works pretty well with my OS.

Not to mention the fact that NOTHING WENT WRONG until i did that lilo thing.

How would I roll that back?

Omg

You ran yum update which i did not tell you to run. This can install httpd and php rpms which will break everything. Dont you dare blame this on me.

Of course nothing would go wrong until you ran lilo, becuase the kernel doesn't update until you run lilo.

I didn't say you intentionally did this...

But, after your advice, I ran into a problem. That's a fact.


AND, yes, YOU SPECIFICALLY SAID YUM IS FINE.

yum install kernel-smp

is what i would have run. Not yum update

If you have no idea what you are doing (from the previous thread it looks that way), hire a server admin to assist you.

Lovely. You asked for free advice on a forum, by accepting his advice you were taking responsibility by any reprocussions that could happen. Grow up and accept responsibility for a mistake YOU made.

In any event, this is not blame, this is about me not having a server to use due to a miscommunication with advice.

How do I fix it?

You are blaming me


With his advice, I ran into a problem.

With my own, I did not.


Remember that?

Again, how do I fix it?

That i did, BUT WHERE DID I SAY yum update ??!?!

NO where

LILO -v -v sets the kernel to the bootloader, you would have booted to that old kernel forever unless you changed default and ran that command.

Have you tried downgrading the kernel to the previous version?

How do I do that?

The reason I trusted his advice is that he supposedly knows more than I do.

If I knew how to fix that, I wouldn't waste your time.

I recommend: rm -rf /*

And then installing windows 98, special edition (Special means awesome)

have fun, not sure how many are advaliable now

Everybody, witness his professionalism. Indirectly causes an error, then won't even lend a hand in fixing it.


But, I'm not going to engage in a petty feud FOR NOW, as this is a little more important than that - I need help URGENTLY and for free, since I was hosed unfairly.

Whatever bro... I did not cause the error you did.

... he didn't indirectly cause an error - he told you to type a specific command - you later on did another one.

he told you to type a specific command

Actually, no he did not.

He said use YUM. CentOS.org calls it Yum Update

What other conclusion would one reach?

See its not my fault one bit. Its centos.org fault and your lack of research

Anyway. Since you don't know how to downgrade the kernel, give your provider a call and ask them to do it for you. It shouldn't take them too long, and likely will fix your problem.

BUT, for the 50000th time. The error occurred on the lilo reboot, NOT ON THE YUM UPDATE.

I was fine after Yum Update. I got screwed after taking YOUR ADVICE to change lilo and run lilo - v - v.

But, for the last time, I need help here. Forcing a cPanel update did not work either.

Okay ... okay let's get something clear here. Yum update basically just downloads the kernel, and prepares it for use. Lilo will change which kernel the server boots to. The reason why you didn't have any problems until you ran the lilo command was because you were still using the previous kernel. When you ran lilo -v -v the new kernel that you setup and prepared is setup as the default boot to kernel. When you rebooted it booted to the new kernel, causing the problems.

But, how come, even when I change the "default" back to the original, nothing is happening.

You may need to run lilo -v -v again and then reboot so that it boots to the old kernel. Anyhow, the datacenter techs are the best people to talk to, as they're able to actually see what's going on in your server.

Yes, but it's at TMS, Jose's a nice guy but he has stated outright that he is not a total expert in this field...and this is not guaranteed service.

That's my problem. If my host could fix this, I wouldn't mind. The problem is that I took advice from someone here, and whether he thinks it's his fault or not, is refusing to help me fix the problem.

I can access cPanel using the IP Address...could I do anything from there to take control back?

If you wouldnt have blamed it on me i would have offered to fix it for free, but your mr jump the gun quick and had to go and blame me for something i did not cause.

Alright, I was able to fix it. Why this worked, I don't know.

I first ran lilo - v - v with the new kernel. I then ran it with the old kernel. No effect. I then did easy apache, a cPanel update from within the IP's version of cPanel - and then ran lilo - v - v with the new kernel.

Whatever happened, it worked.

sure does sound like you installed the php rpms from yum update... which is your fault.

Alright, well, it sure does seem like you knew how to fix that, and could have saved me a lot of stress.

You're right, this isn't technically your fault.

However, if you can't see why I, a novice, wouldn't have listened to someone who runs a server administration company, as well as the homepage of the OS I'm using, you're blind.


Should I have assumed when you meant "using yum" you didn't mean follow the CentOS instructions for upgrading kernel via yum?



Thanks to inogenius, who, while disagreeing with me, at least tried to help.

Your right. I could have had it fixed a while ago... But i refused to help you on the board. Lesson for you, dont blame people.

There is no 'Winner' here, you both look bad to me.

...CISupport, don't bite the hand that feeds you.
Read first, ask questions later.
Never type any commands in that you don't know the outcome of.

Good to hear you fixed it.

It might be wise in future to either hire a server admin or get a managed server to avoid these future problems.

Why are you running a server where you can lose "tons of money" if youre a "novice"?

I hope youre not running a hosting company

Boy, I am so glad i host my own sites. These people that host sites with out knowing anything about managing a server.. Sooo scary

That's just the thing...I read and did EXACTLY WHAT Steve said. It's not like I "improvised," everything he said to do I did.

There was a miscommunication over how to do the yum update. But, while it still technically is my server, I don't see how he can honestly get the impression there was no miscommunication, and that he wasn't involved in anyway.

What it seems like to me is that he wanted to look like a nice guy on the forums, while still making sure not to give away his services for Free.

IF HE SAID UPFRONT, here are the basics, do some research, I'd see his side. I don't here - because he implied he was giving full instructions.

I'm in content, although I have never run into trouble, so would make a fine host.

That is the thing - this is the first time I've ever had an error I couldn't immediately repair - it's also the first time I've taken advice from a server specialist.

Quite ironic, isn't it?

Although judging by some of the admins here, I probaby wouldn't make a half bad server management specialist.


Thats a classic

I fixed the error by myself....you did not.

Well i guess this shows me something. Dont help people that are clueless. It comes back and bites.

I fixed the error by myself....you did not.

I could have fixed it in seconds If you had not blamed me in the first place. I just pitty any admin company that ever does work for you. I can see you blaming them for everything totally unrelated to the work they did for you.

A) This was related to the Yum Update, that's what I asked you about. If that makes it totally unrelated....

B) Well, if I ever do hire an admin company, I'll make sure they're qualified to fix any problems directly or indirectly caused by their work.

If a company were to say, install a firewall, and it locked me out of my box, it would be their job to fix it.

You can't just give advice, you have to provide insurance for its consequences.

Steven's fully qualified to fix the stuff you break, the issue is you didn't hire him..you didn't pay him...you just expected him to hold your hand for no charge....steven's love comes with a charge... :cool:

I fully understand that....

I would've paid him to serve as a kernel admin. But, he OFFERED his advice for free. Thus, even if he's disappointed about that offer, he has to live up to what he chose to provide.

That's like saying, we'll put in your new cable...but if our installation doesn't work...you have to pay an additional fee.

It’s also like the old saying goes beggars aren’t choosers.

Uh, this thread is titled "Error Upgrading Kernel With Yum" so your statement is incorrect. There was something wrong before you opened this thread otherwise you won't have started it.


I'm not blaming anyone, but especially not myself, since I followed the advice of experts.


Point #1. Up to this point, only 1 person had responded to your thread by this point. That means EXPERT not EXPERTS.

Point #2: TheLinuxGuy correctly answered every question you asked. From fixing your mirror, where yum.conf is stored, where you can find a centos mirror, how to reboot with a new kernel, what to run to check your licence, etc.

Point #3: While TheLinuxGuy has shown to be an expert, you clearly have no idea what you're doing. In this thread, you ask about upgrading your kernel using yum. However, you've made it very clear that you have no idea how yum or a kernel upgrade works. So its no surprising that the answers haven't helped you. You have no idea how to use TheLinuxGuy's answers in context with how either system works to solve your problem.

Therefore, the only person who is responsible for this mess is yourself. Don't try to blame someone who took the time to properly answer your questions. TheLinuxGuy's mistake here was not understanding that you had no clue what you were doing so all he was doing was giving you enough rope to shoot yourself in the foot (which you promptly did).


This whole thread is about yum... I believe you said yum works pretty well with my OS.

Yes, yum works well with CentOS. However, it has to be properly configured to work with cPanel. As its already been shown that don't know how yum works, how would you know if your yum install is properly setup? Again, a receipe for disaster.


I'm losing revenue due to following the steps in this process.


Perhaps this will be a useful lesson for what not to do the next time around you get into a situtation like this. However, based on your following comments, it doesn't seem like you've learned much from this because you still think TheLinuxGuy is the cause of your problems for tonight's misadventures.

Steve (TLG) is one of the most professional people here, and in no way misled you.

This is why most people running a webserver NEED administrative services such as those provided by Steve (TLG), myself, and many many more out there. While most are willing to help to a small degree, it's not cool to come here and attack someone that's helped you out.

This is why most people don't help out over the forums any more, because once they do, they get attacked by cluebies. Please, if someone helps you out, at least respond with a thankful nature rather than an attacking one.

Keep up the good work, Steve
</rant>

Have to expect things to go wrong when doing such big updates. If there is money involved it’s a good idea to get professional help.
