How can I resolve certificate issues in Eucalyptus? - eucalyptus

I have recently installed eucalyptus on a Ubuntu 10.04. Everything works fine until I get to the user interface. Whenever I try to get to the store tab I get the following error:
Error 60: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
I have been doing some research and tried to update the certificate, make changes to the /usr/lib/python2.7/dist-packages/imagestore/lib/fetch.py but none of these solutions worked.
I am really stuck and do not know what to do.

I cannot help resolve the issue on Ubuntu and I suspect the Euca version involved is way out date. If you are willing to work on CentOS then you've got two great options
FastStart - this is an awesome bundle of Eucalyptus and CentOS. I use this to spin up a new cloud after each release, including the pre-release of 3.3. Total time to new cloud is roughly 35 minutes.
http://www.eucalyptus.com/download/faststart
Package downloads - This is your standard install method and the only option to pick if you're trying to build a large cloud.

BTW - if you are looking to build a large cloud I also recommend you check out the Reference Architectures. These are Eucalyptus deployment blueprints based on lots of real-world, customer environments. http://eucalyptus.com/eucalyptus-cloud/reference-architectures
If you have other questions, I hope we see you on IRC. It's the #eucalyptus channel on freenode: http://webchat.freenode.net/?channels=eucalyptus
Hope this helps

ACORE API, assistance with errors and deployment

I'm having trouble with setting up ACORE API's and then having them work on a website.
Background:
Azerothcore running 3.3.5 on a debian standalone server, this has the Database, Core files and runs both the world and auth server basically a standard setup that is shown in the how-to wiki.
I also have a standalone web server, on the same subnet, but it's a separate server running linux and normal web server stuff, this has a wordpress installation with azerothcore plugin for user signup etc.
I'm trying to add the player map (https://github.com/azerothcore/playermap) and the ACORE-API set of functions (server status, arenastats, BG que and wow statistics) (https://github.com/azerothcore/acore-api)
Problem:
I understand the acore-api must be run in a container (docker or whatever) on the server, which I have done and it binds to port 3000, I can then go to the local ip:3000 and it brings up this error. (all db's etc are connecting and soap is working)
error 404 when navigating to IP:3000
I do get a few errors when running NPM install seen here: I'm not sure if they would be causing any issues or not.
screenshot of NPM errors on install
But further that, when I put say 'serverstatus' on the webserver (separate server) and configure the config.ts file I can't seem to get anything to display.
I'm not sure what I'm doing wrong but is the same scenario for all of the different functions for the acore-api
How are these meant to be installed and function? I feel I'm missing a vital step.
Likewise, with PLAYERMAP I have edited the comm_conf.php and set the realmd_id, but when loading the page, I do get the map, but the uptime is missing and no players are shown?
Could someone assist if possible?
Seems like an issue with NodeJS version. Update your NodeJS to latest LTS version 16.13.0 (https://nodejs.org)

Install Openstack on single node

I want to install Openstack on CentOS 8(single node). I am having single machine (physical machine) where I want to install all nodes of Openstack. This setup I required for simulation only not production use.
I have tried to install Openstack using packstac 3 times but couldn't success.
I got different issues during installation:
1.In first attempt After installation, I tried to create instance, but not getting console of instances even after it got created successfully.
2. In second attempt, during deployment of instance, network not getting allocated.
3. In third attempt, it got stuck at packstack, puppet testing only.
I have followed below 2 links:
https://computingforgeeks.com/install-openstack-victoria-on-centos/
https://www.google.com/amp/s/www.linuxtechi.com/install-openstack-centos-8-with-packstack/amp/
I followed each and every steps mention in the likns.
I want to create two Ubuntu VMs on Openstack.
Can someone provide me some links/video, where I can get everything which is required to install Openstack on single node and create two Ubuntu VMs and assign network to them and test the connectivity between these two VMS.
Thanks in advance.
I would use official Packstack documentation. Note that you should start with a totally fresh Centos installation; i.e. don't try to install Packstack on a server where a previous installation failed (or succeeded).
You can also try Devstack. Its default configuration requires a smaller machine than Packstack (in my experience, 8GB RAM should be sufficient). Same remark: Start with a fresh installation of Centos or Ubuntu.
Microstack is another alternative. Its advantage is a very simple and quick installation; its disadvantage is a very strange (in my opinion) configuration and not a lot of documentation. However, it is suitable for your purpose. It claims to work on any Linux, Windows and MacOS; it does require snap.
I suggest directly installation onto Ubuntu Server.
some time ago I wrote a serie of posts in which I explained in detail how to install OpenStack Rocky. The 2 first blog posts ([1] and [2]) contain commands, examples, content of configuration files that cover common scenarios and tips for the successful installation of most OpenStack services (keystone, nova, glance, etc.) in a single node, and the third post [3] describes the installation of a computing node. This 3rd post is installed in a different node for the sake of making it easier to understand how nova works, but the installation can be safely carried out in the same node than the other components.
I find that the posts are short enough and are very easy to follow (I use that blog as my installation tips, and so I have used them for several deployments). The only caveat is that it is based on Ubuntu, but if you know about your installation, it should be easy to translate the installation to CentOS (some colleagues have used these tips for CentOS installations).
I tried to install Openstack several times last week (october 2021): a) with CentOS 8 Stream to metal hardware (real server) with devstack - no one version was installed (neither Master nor Xena & Wallaby, version Viktoria & below are not for Stream OS); b) Virtual machine with CentOS 8 Stream installed with packstack - installation was clearly successful (!), quite easy for install (according to official RDO project and its homepage), however there is the real problem with virtual and actual networking: no external network is accessible, router created was OK with external connection (router IP was detected successfully from outside) but no connection was possible from and to instance. So I conclude the Openstack package is not completely documented to resolve problems, however its installation can be quite easy (when successfully finish ;) )
Addition: Of coarse, there are resources with an information how network can be configured, official Openstack docs describes different network configurations as well (however it is difficult to find it for one click and being newbie), but anyway this system requires a lot of time to study before usage.

SBT 1.0+ Resolvers no longer using Credentials?

this is related to the last question I posted on the subject:
SBT Publish to Visual Studio Team Services (Web) Packages Plugin Repo
At the time I wrote that I was running SBT 0.13.16, and was able to make everything work.
My team has attempted since then to upgrade to SBT 1.0.x, and while for a while it seemed to work, it turns out that was only thanks to the cached versions of our libraries in ivy.
Attempting a clean setup using the same technique that worked in SBT 0.13.16 results in no attempt to send authentication information to the servers (and thus, no library download and frustrated devs); verified with Fiddler.
PUBLISHING does work and seems to make proper use of the credentials, but DEPENDENCY RESOLUTION does not, any longer.
Any idea what I'm doing wrong, or how I can replicate the old behavior?
Thanks!
Apparently this was resolved at some point before sbt 1.1.6.

Meteor: what are the best settings in a production environment?

I am developing a meteor application. I noticed that the meteor server sometimes suddently crashes, this makes me think that it might not be optimized for production.
In a production environment, should I consider to add/remove some packages? Which one? And what are the best settings? I just want to make sure to have a reliable server that stay up all the time.
Have you taken a look at meteor up yet? It will set up a production quality server for you. I've used it for several production applications and it works great.
As far as adding/removing packages goes, I've never ran into any problems with installed packages running on production. A couple of my apps have about a dozen or so packages installed. But if you suspect that a package might be causing the problem, I would go to atmosphere and search for your packages and make sure that they haven't been flagged. You'll see a bright red flag next to the package name if it's been flagged by the community as "not working".
Maybe also check for issues on GitHub.
If you do decide to use meteor up, after your app has been uploaded to the server, you can check the log s for any problems.
mup logs -f

Do we have any cli/api to check openstack development version

Do we have any cli/api to check openstack development version..i mean whether my system installed havana or grizzly.I searched the openstack cli/api docs but i don't find any relevant.
OpenStack has a number of elements if you want to verify state.
Each of the component projects and each of the python-client api bindings have their own versions. Then there are configurable options for addressing API versions in REST queries.
I took a crack at building an API for the very purpose of verifying this data as well as all python dependencies a while back with the aim of cross verifying that against a vulnerability database but I simply haven't had the time to bring it to completion.
This would be a very useful feature I think.
You might look at your pip requires if you installed from source. Alternatively you can follow the debian package version chain from dependencies and that should provide good insight into what is installed on your system though it's not exactly verified.
