runnig a webserver - no chance

Lakotaubp

@dobey Your probably right but you never know. They have a rpi, maybe they might try UT on it and see what can be done with UT.

@bforpc Forgive me but what is the usecase to run a web server on a mobile device? It will be slow, it will be unreliable over WiFi and it will drain your battery.

Dear Group,

I have tried the last 3 days without success. Apache is not running under libertine, nginx are running, but - no matter what the error is - it does not found any file in the web root directory.

Only hint - no error - i found in debug logs of nginx are:
2020/10/05 15:47:21 [debug] 9911#9911: *1 http script var: "/"
2020/10/05 15:47:21 [debug] 9911#9911: *1 trying to use dir: "/" "/var/www/html/"
2020/10/05 15:47:21 [debug] 9911#9911: *1 trying to use file: "=404" "/var/www/html=404"
2020/10/05 15:47:21 [debug] 9911#9911: *1 http finalize request: 404, "/?" a:1, c:1
2020/10/05 15:47:21 [debug] 9911#9911: *1 http special response: 404, "/?"
I have tried also running the Web Servers from the root of the nexus 5 it self. This will be working - but breaks the system and then some apps (all web browsers) are not working annymore. morph browser crashes the hole system into a reboot.

Is there a chance, to have ubport up and running and also a web server inkl. php?

Let me try to eschew the philosophical conversation and have a technical one (and ducking my head while doing so;) ).

Can you give more detail about what exactly you tried and what exactly was the result. I understand you installed apache in libertine?! which packages precisely, how did you configure it, start it, test it ...

Thats a very well nice suggestion.

Only some standards.
Like described: If i install apache2, it will not start, because of some restrictions inside libertine - at this moment i cant remember. nginx is starting (the daemon), but no websites will be served out - Browser says alway: page not found, The nginx conf is standard, searching in webroot under /var/www/html - what has exist with content and all needed rights.
Installed i have the packages with pkg install nginx php (and some other dependencys).

In root of ubports i have try to install apache2 or nginx and mc, but - because of less storage in the roor dir, i moved /var/cache/apt and /usr/share/doc to the /userdir storage and linked it back. After that i install nginx what worked well...except for the small thing that the device no longer boots into the desktop - something was broken - yes yes yes ... i had read that, this can be happen and i dont care about it.It was a try.

@bforpc Have you tried lighttpd?
In my attempt to test MotionOS (using lighttpd if i'm not wrong...) in Libertine, i was able to access the Web UI in Morph: https://forums.ubports.com/topic/2570/help-needed-motion-eye-in-a-container?lang=en-GB

Well, it's in the eye of the beholder what is standard ... I personally have no experience with apache, so I wouldn't have a clue what is standard .... well let me just try ... sudo apt install apache2 on my laptop and afterward go to http://localhost shows some default website. ha! that was easy. I somehow feared it was more difficult:) Ok, try again on my deb: libertine-container-manager install-package -p apache2 ... no, it doesn't like that

Setting up apache2 (2.4.18-2ubuntu3.17) ...
/bin/sh: 1: .: Can't open /etc/apache2/envvars
Could not read /etc/apache2/envvars
dpkg: error processing package apache2 (--configure):

Mhm. I guess you'd have to dig into whatever happens in "Setting up". I poked a little bit but .deb packages are still pretty much magic black boxes to me. I don't know where to find the setup code...

Instead of using libertine you could put your server in your home directory and add an upstart service for it. Or create an unconfined app that does the very same, allowing you to use Clickable for compiling, adding dependencies and such.

@jonius
Hi,

can you explain a little bit more, how to do exactly that, what you described?

Dear bforpc,

i tried the same with my Nexus 5 running on UT. I couldn't run

sudo apt install apache2

directly, I got this message:

W: Es wird keine Sperre für schreibgeschützte Sperrdatei /var/lib/dpkg/lock-frontend verwendet.
W: Es wird keine Sperre für schreibgeschützte Sperrdatei /var/lib/dpkg/lock verwendet.

as i learned this IS intentional: askubuntu/sudo-apt-get-install-is-showing-not-using-locking-for-read-only-file-var-lib read the Warnings. Soon after i run into some storage issues, however a soft reset of the phone didnt help. With minimal packages installed my intention worked but the wifi was unstable as well.

Now i even cant remove the packages anymore.

with:

sudo mount -o remount,rw /

you can execute i.e. or more:

sudo apt install apache2

the next try is to install apache2 on libertine and somehow let it run.

@zykrates
You shoult not use apt in UT.
And now you should reinstall OS using ubports installer for avoiding further problems.

zykrates

@keneda i tried to flash it last. It is funny, that the ubports installer didnt wont to reflash on Win10, but it worked on ubuntu

the storage issue was on /dev/loop0 and after flashing there is 282M again free space. If you use the space carefully it worked for me. I forgot this issue and tried to install more apps and then it crashed.

i try apache with libertine now

btw: every iot device (i.e. esp32) has some webserver capabilities. The power consumtion of the nexus 5 is below 0,5W (25mW in Standby)
