Ruby on Rails VPS Deployment Tutorial – How To Deploy Rails Applications To "Cloud" VPS Providers

Ruby on Rails is finest run on a VPS server (if you don’t want to make use of the likes of Heroku) – usually hosted on one of many numerous "cloud" suppliers. While that is fairly customary (and comparatively easy to arrange), what isn’t easy is the way in which wherein it’s a must to arrange the software program operating on the assorted VPS packing containers you’ll have.

The reality is that almost all of establishing a VPS server for the likes of Rails is software program centric – which means that the underlying "VPS" remains to be the identical irrespective of which setup you find yourself utilizing.

That is why it's known as a "stack" – you're mainly putting in numerous "layers" of the system, from the OS to the underlining libraries to the net server & GIT and many others.

When you're desirous about getting your Ruby on Rails utility uploaded and operating on a "cloud" VPS, you'll be finest positioned to have a look at the assorted items of * software program * you'll require to get it operating. This may be finished in numerous other ways, however the underlying necessities are nonetheless the identical. This tutorial goes to clarify learn how to do it …

What's Required to Get A Rails-Powered VPS Operating

Crucial factor is to understand that this "stack" exists on * ALL * methods – whatever the working system or no matter.

The particular software program stack you require is as follows:

  • Working System (Linux or Home windows)
  • System Libraries (OpenSSL, GIT, and many others)
  • Language Interpreters (Ruby / PHP and many others)
  • Software program Packages (Net Server and many others)
  • GIT Repo's + Server Config

The purpose right here is that the above represents the standard "stack" required to get any net server on-line. Net servers are ALL the identical – they’re standardized methods designed to offer customers with the power to "publish" HTML pages on the internet.

The one distinction – and that is particularly pertinent with Rails – is that you simply want what's often called "utility" server software program – which represents the "processing" of dynamic requests. For Rails, that is usually "Passenger" however Puma can be relevant.

To know how these works, I'll briefly clarify the steps required to get all of it working …

Putting in The Numerous Software program Packages

As talked about, 99% of the job is putting in the completely different packages.

To do that, you mainly let the host arrange the server both by their net primarily based interface, or by the API. The API is barely actually for third occasion apps, so it's in all probability not going to be one thing you'll be involved with.

The purpose is that every part after that’s as much as you. Right here's the way you do it …

  1. SSH Entry
    The very first thing it’s essential is acquire SSH entry to the field. That is finished usually by the supplier's net service (Digital Ocean has a "console" applet for instance.This gives you direct entry to the server, and you must be capable of log in utilizing the "root" username (& password delivered by way of electronic mail).
  2. Create "deploy" Person
    After you acquire preliminary SSH entry, you're finest eradicating entry for the "root" person (to stop hackers) and alter the port to one thing aside from 22. This usually means it’s a must to bear in mind the port – however it’s essential ensure that you’ll be able to primarily "block" a lot of the hacking makes an attempt you'll get. On prime of this, it's suggested you create some kind of "deploy" person. This mainly permits you to substitute the "root" person and take away reliance on the default settings for the deployment.
  3. Set up OS-Degree Libraries
    After establishing a "deploy" person, you'll then want to put in the assorted OS-level libraries which can be required to run the assorted functions. These will range relying on which kind of utility you want to use – however will usually embrace a lot of the identical packages.
  4. Set up Programming Languages
    Subsequent, it’s essential set up the assorted programming languages ​​required by your utility. When you're utilizing Ruby on Rails, this can be Ruby. You might also require NodeJS to assist the system execute the assorted Javascript components of your apps.
  5. Set up Net Server Software program
    This can both be Apache or NGinx. Each are supported on all flavors of Linux – and you must be capable of get them engaged on Home windows too.
  6. Set up "Software" Server Software program
    After the net server, you'll want to put in the "utility" server. That is this system which turns HTTP requests over to the Ruby interpreter – permitting in your Rails app to ship HTML responses. For Rails, this can both be Phusion Passenger, or Puma. Establishing both is comparatively sophisticated, so that you'll have to lookup learn how to do it.
  7. Set Up The Numerous Domains In The Server Config Information
    Each NGinx & Apache function a "digital host" system – the place you're capable of "break up" the server amongst completely different domains / apps. By setting them within the config recordsdata, you're capable of decide precisely which apps you're internet hosting in your servers.
  8. Arrange GIT Repo's
    Lastly, it’s essential arrange the assorted GIT repo's that you could be require in your numerous apps. While you can use a "File Supervisor" system – and even FTP – to add recordsdata instantly, GIT is much simpler at dealing with versioned uploads.

By doing the entire above, you'll be capable of get your functions deployed to your personal VPS servers. While not exhaustive, the above is pretty-much what it’s essential get all of it working.
