12:03 AM

hi guys, where would be the best place to have a chat about an apache/php problem im having ?

You can ask in here; no answer guaranteed.

the short version is that apache is offering my php files for download, the longer version is that i did an dist-upgrade debian 6 to 7 with virtualmin and nginx stopped working with 502 errors. so i thought id try getting apache going again as i wouldnt mind using it again. which is where im at...

o.O

Firstly, a dist-upgrade is generally a bad idea... as you can see, things break :\

Why not try to fix the nginx install?

Journeyman Geek

@Bob: You can do staggered spinups in software?

@JourneymanGeek I thought I replied to the message about ext4

12:10 AM

at this stage id be happy to get anything working

Journeyman Geek

@HaydenThring: two possibilities, mimetypes are set wrong, or you don't have mod php installed.

so yeah im happy to get nginx working, it has all my site configs

i believe it runs under fcgi

Journeyman Geek

@Bob: ahh. ext4 isn't a bad idea

@HaydenThring: yeah

@JourneymanGeek Yea, but if he cares that much about reliability...

Something like ZFS is probably a better idea.

i did a reboot and now apache not starting. give me a few mins to work through its error log

(also i have a confession, that the dist-upgrade was done to get myself out of a botched php upgrade from dotdeb)

12:15 AM

TIL Btrfs was declared stable in Linux 3.10

Btrfs (B-tree file system, variously pronounced: "Butter F S", "Butterface", "Better F S", "B-tree F S", or simply by spelling it out) is a GPL-licensed copy-on-write file system for Linux. Development began at Oracle Corporation in 2007. As of August 2014, the file system's on-disk format has been marked as stable. Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems. Chris Mason, the principal Btrfs author, has stated that its goal was "to let Linux scale for the storage that will be available. Scaling is not just about...

Trouble is, RAID 6 support is incomplete

@HaydenThring ...well, that really doesn't help much

do you have a backup?

I'd rather use ext4 and mdadm

@Bob of my websites and databases and the etc and log folders

apache is running again but same problem, also nginx has 502's if i try that.

Journeyman Geek

@DragonLord: anf btrfs is a first class citizen on opensuse

@HaydenThring Anything in the nginx error logs?

Journeyman Geek

12:21 AM

@Bob: ZFS is tricky to set up right

@Bob: 2015/01/20 11:19:41 [error] 6120#0: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 101.170.255.224, server: bonnin.com.au, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9003", host: "www.bonnin.com.au"

@JourneymanGeek Do Btrfs and mdadm play nice?

Journeyman Geek

no idea

You wouldn't need mdam tho

Trouble is, RAID 6 support is incomplete

Journeyman Geek

ahh

12:26 AM

@JourneymanGeek But it works well once you do have it set up.

@HaydenThring Make sure FCGI is running.

Make sure FCGI is installed

Perhaps reinstall the relevant PHP package - did you use php-fpm?

Journeyman Geek

@Bob: That may up the ram requirements, and you'd want a caching SSD

@Bob, php-fpm confuses me i wasnt sure if it should be installed or not, didnt think so, tried it though made no diff, so uninstalled it again. how do i know if i need it ?

Journeyman Geek

You may need it for ngnix

and ngnix needs to be configured to use it

@JourneymanGeek how come some guides dont mention it then ? eg: linode.com/docs/websites/nginx/…

@JourneymanGeek You can do FCGI without FPM...

Journeyman Geek

12:39 AM

oh?

Then ignore what I said. ;p

> PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.

Journeyman Geek

ah hah!

It's the one I see most commonly used/recommended, though.

> Nov 29, 2011
It's official. PHP-FPM is no longer marked as "experimental" as of PHP 5.4.0RC2.

Journeyman Geek

there, ninja edited

so is there a way to tell if i should/would have fpm or fcgi installed ?

(can i just say thanks so much for the help so far)

12:46 AM

@HaydenThring Hard to say without knowing your original setup.

its working

happy

o.O

either 2 things, disabling then enabling nginx website option in virtualmin for that account or

installing these missing php extensions that i found where missing in the apache logs. (nginx didnt mention it)

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/curl.so' - /usr/lib/php5/20100525/curl.so: cannot open shared object file: No such file or directory in Unknown on line 0

@HaydenThring That's because nginx doesn't run PHP

It runs FCGI, and hands off to a separate process.

ok, its not the php modules, it seems disable/enable nginx option for that viltualserver, ill compare tho

12:50 AM

You'll find the PHP logs in a different place.

@Bob ok

ill compare one that works against one that doesnt to see diff

(btw its fcgi in my case)

Okay, so I have to use Btrfs

Ext4 cannot scale to larger than 16 TB without losing the ability to resize the volume (or so it seems)

ok the most obvious diff is that by getting virtualmin to recreate the config files, it goes from this: "fastcgi_pass localhost:9003;" to "fastcgi_pass unix:/var/php-nginx/12963572547638.sock/socket;"

At least not currently.

I'll probably use Btrfs in any case—the basic features are stable for the most part.

1:20 AM

I'll test this with a bunch of virtual disks in Hyper-V—will report back with the results

1:31 AM

I wonder if there is a correlation between low quality questions and those that open with "So.."

1:45 AM

11 hours ago, by DragonLord

I'm hoping to ramp things up to 5-10 answers a week

nope success was short lived, only working for 1 domain, not the rest

@Bob, @JourneymanGeek: I'm curious if I can scale up to 30+ answers a week, 150+ answers a month without compromising answer quality or moderation work (think Jon Skeet)

Well, we can always dream

Journeyman Geek

@DragonLord: skeet's a specialist tho

and SO has MUCH more volume than we do

(harrymc does about 20-30 answers a month)

Journeyman Geek

ahem

2:00 AM

Well, doing even 3 answers a day is exhausting for me, look at the work it took for me to earn the Bill Lumburgh hat during Winter Bash

Journeyman Geek

Many of which are somewhat... derivative of google searches.

Not to mention the fact that I maintain my answers for at least three full days since the last activity on the question

I stand by every answer I write, and I'm not sure if this can scale to 3-5 answers a day—I'd probably have 20+ tabs open just for active questions I've answered

It's still a leap of faith for me each time I hit the Post Your Answer button, even 300 answers later

Journeyman Geek

heh

burnout

I try to just post the best answer I can. I try not to think about it otherwise ;p.

Skeet at times posts 10+ answers a day

I'd love to do this if I had the knowledge

I wonder if it's okay to dig up old questions to do this

I can't imagine 50+ tabs just for Super User and getting notifications every hour in my Stack Exchange inbox

As I've said before, I don't "fire and forget" answers.

Jan 10 '14 at 15:20, by allquixotic

man, I've spent 10 minutes looking through the unanswered question list on SO and almost every single one of them is about some technology I've never even heard of, much less know how to answer

that's essentially what happens with most of us

2:25 AM

Green drives also don't have TLER, which can cause problems if one of the disks malfunctions. The Red drives have special firmware and undergo extra validation to ensure reliable operation in RAID. This validation costs a lot of time and money, so even if the disk media on a Red is exactly the same as that on a Green, the cost is recouped through a separate, more expensive product line made for this purpose rather than raising the price of every Green drive sold for a feature that is used only in a small minority of configurations. The latter makes absolutely no business sense. — DragonLord 3 mins ago

Well, Jon Skeet is not as active as he once was.

I'll challenge myself and try to post at least 20 answers from today to UTC end-of-day January 31, 2015 (before 7:00 PM here in New York)

I might even shoot for 50 answers

All within less than 12 days.

@JourneymanGeek, you've discussed burnout before, so I'm wondering if you think this is a really bad idea or if I should go ahead and try it

...and yes, I have grad coursework to handle at the same time.

@DragonLord you know your own limits, no?

2:40 AM

N.B. Jon Skeet does this even as a busy professional

(btw, the site only gets ~170 q/day, so you may see more rubbish since 90% of everything is crap)

I know this sounds like a Really Bad Idea™, but I'll give it a shot anyway

@Bob , feel like helping out any more ?

anyone know nginx ?

yes it seems it is enough...

@JourneymanGeek I'm very sorry to say that your fears have come true. I cannot contribute at my full pace any longer and may retire from Stack Exchange completely within the next few months.

I suppose the experiment is to be tried

20+ answers a week, 100 answers a month

I'm not sure I'm risking that much

It'll be a fun experiment, reputation and all

Maybe bring things up to Jon Skeet levels, 50+ answers a week?

300+ answers a month?

@Bob Too much text, please summarize to Tweet-length and overlay it on a fitting image so that it can be shared on Facebook. Thanks

@OliverSalzburg It's seriously awesome.

> The concept was pioneered by Adrian Thompson at the University of Sussex, England, who in 1996 evolved a tone discriminator using fewer than 40 programmable logic gates and no clock signal in a FPGA. This is a remarkably small design for such a device and relied on exploiting peculiarities of the hardware that engineers normally avoid. For example, one group of gates has no logical connection to the rest of the circuit, yet is crucial to its function.

i would open it up for bounty if i could im so keen to get it fixed and my sites back online

Commenting it out was the first thing I did. But your comment did lead me to the right solution. I checked phpinfo() and discovered that MAMP was using a different php.ini file than I expected. (It was MAMP/bin/php/php5.4.3/conf/php.ini instead of MAMP/conf/php5.4.3/php.ini.) Sure enough, it wasn't commented out in that location. — redwall_hp Oct 19 '12 at 0:21

i have commented in user php.ini, and /etc php.ini's all i can find

Journeyman Geek

man. Its quiet at work. I hope we don't get with a deluge of tickets at punch out time.

8:51 AM

i know its loading the /home/user/etc one (though ive edited them all) as if i edit the PHPRC variable in the fcgi startup script to a different users etc folder (an account that works) it makes that account not have the error too

9:10 AM

@HaydenThring grep through everything

might be some script somewhere

also if i rename the /home/user/etc/php5/php.ini it fixes it, as it reverts to the /etc/php5 one , even though both have the option commented... i have used find to find any more. i will try grep now though

its reverted.... i feel stupid, why would it be reverting ?

BIOS is a stupid, stupid thing (see: no actual spec)

@NateKerkhofs: the site? no

the channel? who knows ;p

UEFI is really much better than BIOS, but it also places a whole bunch of new requirements to boot from a disk

Journeyman Geek

@DragonLord: That may be OS dependant

SHOULD work, in theory on modern OSes

You need a UEFI partition with some files to actually boot on an UEFI machine

I haven't had a chance to read the UEFI spec—it's just huge

@JourneymanGeek, I'm just creating the virtual disks to test Btrfs on mdadm in a Hyper-V virtual machine

Journeyman Geek

ahh

should work

8 virtual disks each 16 GB

Just to test scalability

...and to see how well behaved the system is when adding disks and expanding the array as well as what happens when a disk is disconnected

this is super wierd. My desktop stopped seeing all my windows smb hosts all of a sudden

All of the virtual disks are being placed on my hard drive

They'll be hooked up to an SAS controller provided by the VMM

Will be AFK for 30-45 minutes, hang on...

@DragonLord ...not a whole bunch, no

from the perspective of the OS, it's no more complex than a legacy BIOS boot

just better defined
