Ubuntu – How to install rabbitmq management plugin (rabbitmq-plugins)

rabbitmqUbuntu

Brief:
Is there a way to install rabbitmq-plugins via a ubuntu package?

Details:

I have rabbitmq running ok in my ubuntu system, and now I'm trying to monitor what's going on via the management plugin. I'm following rabbitmq.com/management.html instructions, but can't execute

rabbitmq-plugins enable rabbitmq_management

because my system does not have rabbitmq-plugins installed.

It's Ubuntu 1110, and came with rabbitmq installed as a package (aptitude install rabbitmq-server librabbitmq-dev). The config and the server are running fine (the installed version is 2.5.0).

Thought that the plugin would get installed by installing "sudo aptitude install rabbitmq-plugins-common", but doing that does not install rabbitmq-plugins.

Is there a package that will install the plugin? I'd like to avoid if possible having to purge the rabbitmq server that is running ok, and then reinstall it via a download + build from source, all just to get the plugin.

Thanks.

  rabbitmq_management

Plugin configuration has changed. Restart RabbitMQ for changes to take effect.

Check the Web UI

on your browser try http://localhost:55672 (or http://localhost:15672 for newer versions of rabbitmq) & login via default user and password which is guest:guest & you will be able to see it all.

Hope it helps.

Jquery – Backbone.js, Underscore.js : template images preloading

I don't think you necessarily need a library for this, unless there's one specifically for use with templates. As detailed in these related questions, preloading images is relatively simple:

$("<img />").attr("src", url);

will preload the image at url. It's pretty obvious that you can apply this easily to an array (here using $.each for concise syntax):

function preload(urls) {
    $.each(urls, function(i, url) {
        $("<img />").attr("src", url);
    });
}
preload(['/images/1.png', '/images/2.png', ... ]);

You don't need a library for this. The hard part, in your case, is generating the list of URLs to preload. It's impossible to know the best approach here without understanding your templating system better, but here are a few approaches:

If you have your templates available as DOM objects in memory, then you can loop through them using something like $('img').map(function() { return $(this).attr('href') }) to find the URLs. But if you're using Underscore templates in <script> tags and you don't make them into DOM objects until you render the view, then this is unlikely to work - it's going to be a pain and somewhat processor-intensive to render them with dummy data just for the purpose of extracting URLs.
If you use a build system like Ant, and if your templates are fairly separate from your other code (e.g. each template in a separate file), then you might consider using regex to parse the templates for URLs and then sticking them into an array in a Javascript file, which you can use for input to your preloader. This is a pretty complicated build task, but it's probably the best option from a performance standpoint, as all the template parsing happens at build time, not at run time.
Another build system approach, probably simpler, would be to put all images you want to preload into a given directory, and then put every file under that directory into the Javascript array. This is probably the easiest approach with Ant, though it might require you to revise your directory structure for images.
You can always make your array of URLs by hand, but it will be a pain to keep it up to date with a complex set of templates.
If you have a complex app and you want to only preload certain images at any given time, you'll probably need to identify those images by hand, and then call preload(upcomingImages) at the appropriate time for the appropriate set of images.

Run “rabbitmq-plugins enable rabbitmq_management” .. failed

check this link: https://www.rabbitmq.com/windows-quirks.html

This makes it impossible to use rabbitmqctl.

Workarounds:

Run the installer as an administrator or Copy the file .erlang.cookie manually from %SystemRoot% to %HOMEDRIVE%%HOMEPATH%.
