FOOD FOR THOUGHT Incredible PBX with Owncloud Raspberry Pi 3

[wile2u]

Has anyone Installed Owncloud along Incredible PBX on a Raspberry Pi 3?

 

[krzykat]

I've put owncloud on an incredible install, but never on a Rasberry Pi.

I have tried it a few times, and keep getting a http error 500 among other things.. I figured I would use the pre existing MySql server and apache.. But i felt no love.. I'll try again soon. Just got frustrated with it.

There's no reason it shouldn't work, it's just a php app. I suggest run it inside an LXC container.

That sounds like a great idea until I read this

That thread is from 6 months to over a year ago.
Check out this thread for the successful way to do LXC:

LXC on a raspberry with the containers expected to do "real-time" stuff ? (I can't see that as viable)

Don't worry @dicko it's working great. The "real time" app, asterisk, is running at the native level on the machine. Owncloud is a non-real time app and it's the one running in the LXC container.
LXC is 96% to 100% as fast as native.

Denial is not just a river in Egypt. As you will find maybe sooner, maybe later, the Rasberry is a great device, it is is fundamentally inappropriate for PBX. I would suggest a cheap NUC, it comes with a case.

@wile2u The 500 internal server error means the web server is misconfigured for owncloud, check the apache logs to find out what the problem is in the web server configuration.
On Raspberry Pi 3, running owncloud is fastest using nginx as web server and php 7, which is 40-50% faster than php 5, and nginx uses much less memory than apache, so these two together makes the most out of what you have, 1GB ram and the A53 ARM v8 64 bit 4-core processor.

@dicko For comparison the RPi3 A53 ARM v8 scores 685 on UnixBench Multi Core 4 cores 4 threads. As unbelievable as it sounds, the RPi3 actually scored better than the previous generation Amazon AWS m1.large general purpose server instance, which scored 609, running on 1 dedicated 64 bit core (2 virtual cpu cores due to Intel hyper threads) and 7.5GB RAM.
The RPi3 is slow when compared to a recent Intel Atom C2750 which scores 4439 UnixBench Multi Threaded, but that has 8 cores 8 threads compared to the RPi 3 with 4 cpus 4 threads.
Rackspace 2GB Dallas UnixBench scores 549.
Intel Xeon E3-1230v3 scores 8498.
The RPi3 is an incredible value - as good as the last generation AWS m1.large performance for a one time price $50 for the full kit including case. Is it fast enough to run as a PBX while also occasionally syncing files as an Owncloud NAS? Or do you want a fast PC NUC running the Intel Atom C2750 for $200+ ? That's up to you.

If you are happy with the power of a Raspberry, then please use it, when it breaks (which it will . . .. ) , you WILL regret it, I have nothing more to say.

@wile2u The achilles heel of the RPi is the SD card. Even a high quality durable SD card will eventually wear out from writes. To make your RPi3 SD card run forever reliably and trouble free (or for way longer than it would otherwise) the filesystem needs to be turned read-only as described here step by step:
