Do I have to install Ruby on my Apache server to run scripts


You can probably run the script on your notebook directly.

Try creating an example script like this:

echo "puts 'hello'" > example.rb
ruby example.rb

That should print:

hello

You can run any Ruby code that way.

You can also make the script executable.

Edit example.rb so it reads like this:

 #!/usr/bin/env ruby
 puts 'hello'

Then on the command line, make the script executable:

 chmod +x example.rb

Then run it:

 ./example.rb

If you are building something more like a Rails app, and you want to run it on a remote webserver that runs Apache:

  1. On the remote webserver, you must install Ruby. I personally like ruby-install better than rbenv and rvm.

  2. Install a web application server. I personally like Passenger for Apache.

  3. Configure Apache. The Passenger gem will tell you how to do this.

  4. Restart Apache.

SQL Server 2014 Unattended Install
I don't know what else you're using, but you don't need to use a domain user for replication. You can use a SQL account if you'd like (the documentation says so). For the password issue, take a look at the list of parameters you can pass setup.exe (here). You can mix and match parameters and a config.ini. As such, you can set it up such that all you specify via command line switches is the variou

External Apache tomcat Server
The reason we use external server during development is that the server integrated with Eclipse works most of the time but not all of the time. This you will notice when there are multiple number of web application being deployed as part of the development in your Eclipse and you start and stop Tomcat a number of times to refresh web applications in rapid succession. The problems that can happen a

Failed to start Apache Web Server
When using php with a fastCGI proxy or PHP-FPM, the PHP runtime is not longer embedded in the apache runtime process. This will improve performance of your Apache webserver and PHP, since processes are stored in memory separate from each other, even after the request is server. However this does mean that php admin values can no longer be stored in the apache configuration, as is possible when ru
