QA » openQA Project

Thinking simply not using systemd might be an easy alternative I tried that. Except with 80 being unavailable I couldn't easily change the ports and couldn't find any docs on how to change that easily:

sudo sed -i "s@listen       80;@listen       8080;@g" /etc/nginx/nginx.conf
sudo systemctl enable --now nginx
sudo sed -i "s@Listen 80@Listen 9090@g" /etc/apache2/listen.conf
sudo systemctl enable --now apache2

Next step try and run openQA from packages:

$ zypper in openQA-single-instance
[...]
$ sudo systemctl restart openqa-webui
A dependency job for openqa-webui.service failed. See 'journalctl -xe' for details.
[...]postgresql-script[...]Cannot find an active PostgreSQL server binary. Please install one of the PostgreSQL[...]

Somehow postgresql is installed but unable to find itself?

Removed postgresql and re-installed openqa-single-instance. All services run just fine now. Must have been some issue with packages not getting installed correctly before?

Final missing step:

$ sudo /usr/share/openqa/script/configure-web-proxy -p apache2

Unfortunately this doesn't work with nginx:

$ sudo /usr/share/openqa/script/configure-web-proxy -p nginx
zone "upstream_webui" is too small in /etc/nginx/vhosts.d/openqa-upstreams.inc:2
configuration file /etc/nginx/nginx.conf test failed

This says zone upstream_webui 64k; which is part of the ngx_http_upstream module. Upstream docs don't really say what it means. Removing it results in an error (zero size).

Looks like 1000k works? I feel like this would be worth documenting but I don't understand what it means.

The docs state "Defines the name and size of the shared memory zone that keeps the group’s configuration and run-time state that are shared between worker processes.". So it shouldn't need big values but it should fit reasonably well in a users memory. "64k" sounds fine (I guess we're talking bytes? So 64kb?) and I would argue the exact value with a "reasonable guess" ;)

It would seem 64k is "not enough" on my system, either because I'm using containers or because it's arm64. I wonder if this could be related to pagesize? It's 16K on my host.

It seems like the argument processing isn't working properly. So configure-web-proxy -p --port 8080 is ignoring the port and configure-web-proxy -P 9090 fails with "invalid option". I'm investigating why this is the case.

So I found an upstream issue about the minimum zone size afterall stating it must be 8 * ngx_pagesize which would indeed be 128k on my system:

Merged.

Now waiting on a second approval for https://github.com/os-autoinst/openQA/pull/5769

I added another review comment but we're getting very close to merging this as well

I know that it took very long to get https://github.com/os-autoinst/openQA/pull/5769 merged but are you sure that's enough for the team to know how to setup apache+nginx and quickly switch between those?

So this would mean the following line failed? The code before that is the same.

test -n "$web_port" && sed -i "s/^Listen.*$/Listen $web_port/" /etc/apache2/listen.conf

Actually a2enmod must be failing? Since the test shows none of the "..." already present messages?

Still guessing since I can't make this fail, which is what the test does:

zypper in openQA-local-db apache2
./script/configure-web-proxy

https://github.com/os-autoinst/openQA/pull/5793 A revert if nothing else. I have no idea how to reproduce this or what could cause a2enmod to fail with no error message.
