I want to know how to build a rails server and host an app on it locally. I know I can use heroku or aws but in the case of this app I can’t, the database should be hosted locally in the company for security reasons; they do not want to store their data on servers that are not theirs.
How do I start?
What are the main things to consider?
Do I host on heroku and link the local database to the site or do I host them all in the same place?
How much power does the machine need for around 10-20k users?
What OS should I use Ubuntu or what?
Would really appreciate if you have any tutorials or article links.
You can just use ngrok. It doesn't require any side server deployments.

As the title suggests, how can I host a Ruby on Rails application on a home server. I want to be able to develop on linux and then deploy on a server running linux. I know there's PaaS out there that help with deployment and host but for a specific job I need to be able to do it on a computer that will act as a server.
Your phrasing 'run a RoR project on a local computer for production' is a little strange.
If you just want to do development on your PC and have somewhere that will host your production app for free and you can push to from your PC (i.e. the way most development works) you want Heroku.
If you literally want to use your computer as the server for a production app you can use something like Ngrok, which creates a tunnel from the web to your localhost. However you would definitely not want to run most applications like this because if you ever shut down or even closed your computer the site would stop working. Additionally I would guess there's security concerns with using your computer as a server for a publicly accessible URL for any extended period, though I don't know that for sure.
So lately, I offer myself a Mac Mini which I want to use as a server (Websites, caching, Xcode Server (which is not working), VPN (which is not working), and stuff). Currently it is running macOS Sierra (10.12.4) with Server.app (5.3) installed. I've successfully enabled Websites & DNS service so my server is accessible from the outside. I have a trusted and valid SSL certificate.
The problem is...
...I don't know how to setup the server to be a production server for Ruby On Rails.
Want I want
To host a web app using Ruby On Rails on macOS server (www.example.com)
To know how to setup the server app to serve a web app
To host a Git repository for the web app code
I looked at the settings for Websites service in the Server app but I didn't find any options for other than PHP and Python.
What I know
My MacBook is already setup with Ruby 2.4 and Rails 5.0. I know how to install Rails for development purpose
Even if it's not straight-forward, post any help you have.
One of my guesses is that I could forward the port opened for the website without specifying a folder where the files are in the Server app.
I'd be pleased of you inlight in some way to achieve my goal.
I am pretty sure that you don't want to actually run production off of your mac mini. That said once you have your rails app running you can run rails s to run your server locally. If you want a production site you should look into either heroku or AWS elastic beanstalk for deployment.
I have an application developed by Grails 2.5.1 , i need PaaS provider to deploy it for production use , but must got these options :
SMTP server as my application needs to send emails
preferred to have access to file system but not necessary
MYSql DB
Able to deploy PHP applications in it.
Easy to deploy application's packages on
Good customer support
some adviced with Jelastic , but unfortunately they don't have SMTP server , and Heroku the deploying in it is a little bit hard.
any recommendations?
I would recommend Heroku or Elastic Beanstalk. Amazon RDS for MySQL as a Service, or Aurora which is MySQL compatible.
Not sure what you mean by "able to deploy PHP". You won't be able to run a PHP app and a Grails/Java app on the same PaaS server, but you could spin up a separate PHP app on the same PaaS.
You could use Amazon SES to send emails, or a SendGrid account. Email server really shouldn't be a deciding factor.

It is very easy to add SMTP to Jelastic.
All you need to set up your SMPT Server is here.
Also, how to use external SMTP Server in your environment - is here.
With reference to the rest of your list Jelastic provides:
Access to file system (FTP/FTPS, SFTP/FISH, WebDAV, Dashboard)
MYSql DB
Able to deploy PHP applications in it
Easy to deploy application's packages on (Direct, GIT/SVN, Bitbucket)
Good customer support (You can choose hoster by your significant criteria here).
Have a nice day,

I'm able to run rails s through ssh successfully and see the app start up just as it does on my own machine but I'm unable to access the app from the web. The app is directly under the home folder and I have a symbolic link pointing from public_html to the public folder of my rails app, just as this tutorial explains. I even tried setting up a subdomain and every other step in the tutorial to no avail. Any help would be highly appreciated.
You need an application server like Phusion Passenger, Unicorn or puma to run a Ruby app in a production environment. Typically, you'll integrate the application server into a web server's (Apache, nginx) environment.
I don't know about your hoster, but if you have root access, then you can probably use any of these application servers.
The built-in server you start by running rails server is only meant for testing purposes on your local machine. It has not been made with security, performance, stability or any other production-environment criteria in mind.
Is it feasible to have a Ruby on Rails app, which is:
a) deployed on Heroku, and
b) working with a remote SQL Server database?
I take it that I'll need unixODBC installed on Heroku, but I cannot find a way to do so. Is this possible?
Or, is there any other way (without ODBC?) to accomplish this?
Thank you very much for any guidance or tip.
Updated:
Some info on the subject:
1) Heroku pre-installs both unixODBC and FreeTDS by default, so you already have them.
2) Also, it is possible to run shell commands via Heroku Console in backticks, e.g.:
heroku console
`odbcinst`
(runs "odbcinst" command in Heroku shell and shows the result)
3) You do not have access to filesystem outside of your slice where the packages are installed. If you only need a driver path, Heroku support can provide it (/usr/lib/odbc/libtdsodbc.so in my case).
4) You cannot run sudo commands in Heroku shell.
At the moment, to connect to MS SQL Server you at least need to append ‘freetds.conf’ file. Even when using tinyTDS (there is an open ticket#2 in tinyTDS gitgub issue page). DSN-less connection instructions from "wiki.rubyonrails.org SLASH database-support SLASH ms-sql" didn’t work for me, I guess this connection requires some extra-configuration either.
‘freetds.conf’ cannot be modified without sudo. Therefore, I conclude that currently there is no way to make MS SQL and Heroku work together.
I’ve managed to set up this connection with EngineYard and activerecord-sqlserver-adapter.
I followed these instructions:
https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/wiki/Platform-Installation---Ubuntu
(there are only some filepath differences, e.g. ‘odbc.ini’ is located in ‘/etc/unicodbc’, not in ‘/etc’ - this is easy to work out).
I installed 'unixODBC' and 'freetds' packages using EY Unix Packages feature, and made all configurations manually through SSH. Sudo is available in EY (no password required). There is also Chef Recepes feature to automate those configurations (seems to be pretty easy, I'm going to try it tomorrow).
Hope this is helpful.
It is possible.
Because Heroku copies/symlinks its own config/database.yml over whatever you supply in your repository, you may need to take additional steps (e.g. in config/environments/production.rb or in config/initializers/remote_mssql_from_heroku.rb) to set up your application appropriately.
You will face the challenge, however, that traffic from Heroku to your MSSQL database will traverse the public internet. By default, this traffic will not be encrypted. Potentially everyone in the world will be able to monitor your traffic between your Heroku application and your database, and even alter the traffic in-flight, whether for benign or malicious purpose, without you being able to detect it. MS SQL offers the capability to connect over SSL. This capability requires explicit configuration in the MSSQL server, so you must be able to access and modify that configuration. Additionally, this configuration requires that your client library be up-to-date and capable of talking with MSSQL over SSL. Note that MSSQL server will enforce that your server certificate list a Common Name or Subject Alternative Name exactly matching or wildcard-matching the server's FQDN (at least, the FQDN that the server knows about), and that the client use an FQDN for the server exactly matching or wildcard-matching one of the names on the certificate.
I've successfully used the following article which uses Heroku's newer buildpack feature to use TinyTDS and connect remotely to SQL Server 2008 R2. I'm still investigating how I could encrypt traffic. Hope this helps others!

We're having a similar problem where we're needing to import old data from a SQL Server database into our new app. The data isn't a straight table import, but needs to undergo some processing and conversions. We've built an import layer for this which lives in a private gem, so as to not pollute the new app with the old data conversion issues. This approach is also designed to permit incremental updates, as we get closer to launch we'll keep syncing records up to the moment of switch-over.
Heroku told us that it's not trivial to connect to SQLServer, in particular as they don't support FreeTDS. Their support staff recommended to run an instance with the import gem from a laptop in our office and configure it to connect to their database (which requires a dedicated DB, not the free shared one). This sounded like the most palatable approach to us.
Secondly, regarding security that was mentioned by #Justice, we discussed configuring SSL for SQLServer with the hosting company and they pointed out the complexities of this. They recommended VPN as an easier solution. As we don't have office-side VPN hardware, the simplest and free solution proved to be an SSH tunnel.
We've set up an SSH tunnel from the laptop to the SQLServer Windows box. That was straightforward. We had CopSSH installed on Windows (which comes with a Linux shell, by the way) and we were able to simply set up a tunnel, having the laptop talk to localhost for its SQLServer connection, i.e.:
ssh -L 1433:localhost:1433 user#windows_server_name
I did not know Heroku has FreeTDS on it? I was told they did not. TinyTDS if used with FreeTDS 0.91 can have a zero freetds.conf dependency and be driving by runtime connection args. We are looking into building an Ubuntu 10.4 native gem that statically links 0.91 with OpenSSL so you can just drop it into Heroku and us it to connect to Azure and/or you own outside DB.
