[quote=“ianabc, post: 32830, member: 24548”]OK, I think apache is working but that your php setup might be broken. That script should be getting executed on the server, not offered for download. You might need to apt-get install the php packages again.

Could you just confirm that the apache startup script is indeed working, first press Ctrl-C to kill off the apache debug session, then run the actual startup script, here is the output from my system
[CODE]
$ sudo /etc/init.d/apache2 start
$ ps -ef | grep apache
root 20307 1 0 16:21 ? 00:00:00 /usr/sbin/apache2 -k start
www-data 20312 20307 0 16:21 ? 00:00:00 /usr/sbin/apache2 -k start

Once we know that apache is fine we can[S] start fixing php [/S](looks fixed)[/quote]

That’s a problem, the startup script (/etc/init.d/apache2) isn’t exiting correctly.

Tom Elliott

Fresh install would probably work.

When doing the fresh install, don’t install LAMP.

What’s LAMP?

Tom Elliott

Linux, Apache, Mysql, PHP

(Don’t choose webserver, mysql server, or what have you)

I always do minimal install.

NDNtech

So how would I do a minimal install, I don’t think I’m following you. (Sorry, it’s been a long day in this tiny room in front of this server)

ianabc

I think I agree with Tom about the install, you would probably be able to fix the install but a reinstall might be less of a headache. When you are running the ubuntu install DVD just tell it you don’t need a webserver installed - the fog installer will do that for you later.

ianabc

I’d be interested to see the contents of the /etc/init.d/apache2 file if you have it before you reinstall though.

NDNtech

Okay. I had issues with my install too. I couldn’t do a regular install for some reason. I had to boot into the live OS and install from there. In the normal install I kept seeing messages in the command area saying it didn’t have permissions to do things, and then it would error out and say it didn’t know where to install GRUB.

I had a feeling that maybe it’s because I’m using RAID, but I couldn’t find any supporting info on that. I’m using RAID5 on a Dell PowerEdge R610 if that makes any difference. lol

[quote=“NDNtech, post: 32845, member: 23658”]Okay. I had issues with my install too. I couldn’t do a regular install for some reason. I had to boot into the live OS and install from there. In the normal install I kept seeing messages in the command area saying it didn’t have permissions to do things, and then it would error out and say it didn’t know where to install GRUB.

I had a feeling that maybe it’s because I’m using RAID, but I couldn’t find any supporting info on that. I’m using RAID5 on a Dell PowerEdge R610 if that makes any difference. lol[/quote]

I have similar hardware but I’m using CentOS instead of Ubuntu. If you configure the RAID5 in hardware then I think you can just pretend like it’s a simple SATA disk in the installer (i.e. Don’t tell it about the RAID configuration - let the hardware manage that). The installer messages sound weird, what do you mean by the “normal install”?

NDNtech

I’m in the Ubuntu installer and I don’t see that option, It just goes through the steps until it gets to the screen to select a partition

NDNtech

By normal install, I mean just the wizard. I don’t know how to explain it. It’s the one that’s not the live boot of ubuntu

ianabc

You should do a full reinstall from the CD or DVD, running the wizard will usually try to preserve some of your configuration files which seems to be causing the problems. Make sure you backup anything that is on there you want to keep then boot from a CD or DVD. Ubuntu has a server image which might be a better fit than the live CD.

[url]http://releases.ubuntu.com/12.04[/url]

[url]http://releases.ubuntu.com/12.04/ubuntu-12.04.4-server-amd64.iso[/url]

I can’t remember the install process in detail but if you are asked what software you want to install just make sure you don’t install a web server or mysql or anything like that. There might even be a “minimal” option.

Once it is installed give the fog installer a go again.

NDNtech

So I should be using Ubuntu Server instead of desktop?

ianabc

That is just my personal recommendation, not a Fog recommendation! The desktop installer generally installs a bunch of stuff I’ll never use on a fog server. I actually use CentOS for my fog servers but most people seem to choose Ubuntu and both should work.

I’m struggling to remember now but I think that even when you install from liveCD it might as you if you want to “upgrade” rather than reinstall. You definitely want to avoid that! As I said above, you want treat the system as a completely new install.

NDNtech

Yeah, I always do the clean install, it does have the upgrade option pre-selected as if it’s an amazing idea. Well I’m downloading the server version ISO right now and will reinstall it tomorrow. I have a feeling my boss want me off the clock lol
