chatnaut / arclight Goto Github PK

hey.

i want to give it a try. running on ubuntu 20.04.5

install complete. reboot.

Error: Arc api not running
Failed to start PM2 process manager.

This project is really neat, but there's two different solutions for managing KVM, and it's not clear which category this project falls into too. One of them is exactly what I'm looking for, and one I'm avoiding.

1. An appliance-style interface that completely takes over the OS and modifies it, with your application existing per-server. This would be something like proxmox.
2. An application that can exist anywhere, including a VM, possibly manually deployed on top of host it manages, which uses APIs like libvirt, in order to manage servers. This would be something more like Cockpit I think.

I'm looking for option 2, and it's not clear which this is.

Could you clear my doubts about the tool. I've been looking for a long time for a web tool to manage KVM. I don't want to use Xenserver anymore.

1- Is it possible to manage multiple QEMU/KVM nodes with the same interface?

2- Is there any official docker image?

3- With this interface is it possible to manage High Availability (HA) in KVM?

i've enabled SSL in apache by using a letsencrypt certificate, however when actived opening a console seems impossible.

All attempts end in $HOST refused to connect.

When i access the Webgui on HTTP, everything works fine.

Ubuntu 22.04.1 LTS

Hello, I'm running ubuntu 20.04. I've installed arclight v2 using the script provided. Installation is successful. But when I login it shows "Arc api not running in ui" with red highlighter. @jonatan5524 @elondust @S4nfs Also by looking into the script I manually executed the command "pm2 start ecosystem.config.js" after reboot. Still not working.

The following link is referencing the same page:
https://github.com/Chatnaut/Arclight#-getting-started

fix proposal: link them to the documentation pages

I'd love to try this out but when installing on a fresh Debian 11 install, you get this error from line #52.

apache2 is already the newest version (2.4.54-1~deb11u1).
0 upgraded, 0 newly installed, 0 to remove and 79 not upgraded.

Package lsb-core is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'lsb-core' has no installation candidate

I tried removing that to see if a depreciated lib was really required and it later gives an error because of this output from lsb_release

No LSB modules are available

Is Debian unsupported or will there be a patch or workaround soon for this?

After installing and setting up reverse proxy. I can't login to the control panel, it is giving out Error: Arc api not running.

It's a simple matter to clean and lint your shell scripts with tools like shellcheck and others.

There are some pretty odd constructs in your scripts which could use some additional attention, especially since they're intended to be run as root.

For example:

if [ $(egrep -c '(vmx|svm)' /proc/cpuinfo) -eq 0 ]; then

Why not just use kvm-ok, like other modern architectures are using. Simply having the CPU flags exposed doesn't guarantee they can be used for successful virtualization.

Another odd one I found:

apt install php-dev php-pear -y
apt-get install mongodb
sudo apt install -y php-dev

Why are these 3 separate commands, and why three separate ways of executing them? Why is php-dev being installed twice?

How about just:

sudo apt -y install php-dev php-pear mongodb

This is done in a couple of places. Let's fix that first.

Also, why these two:

tar -xzf v2.0.0.tar.gz
mv Arclight-2.0.0 arclight

When you can just do:

tar -xzf v2.0.0.tar.gz -C arclight

You're also not doing any error checking on these commands, if they fail, or if commands you expect to be there are not (like a2enmod).

And using service has been deprecated long ago. You want systemctl, so you can use the more modern systemd way of managing services.

This, is also bad, and overwrites the user's intended Python interpreter, without their knowledge:

ln -s /usr/bin/python3 /usr/bin/python

Don't do that. Use the proper Debian facilities, dpkg-divert or dpkg-reconfigure python3.

It's a great start for a v0.0 of your project, but let's keep it clean, POSIX correct, and secure enough that it won't break an existing user's system without lots of untangling.
