Pow is a Rack server for OS X. It’s quick and easy to use and lets you skip that whole update an Apache file, then edit /etc/hosts, ethane move a file, then run an app type of process. To get started with Pow, curl it down and pipe it to a shell, then provide the password when prompted to do so: odr:~ charlesedge$ curl get.pow.cx | sh % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 9039 100 9039 0 0 10995 0 --:--:-- --:--:-- --:--:-- 10996 *** Installing Pow 0.5.0... *** Installing local configuration files... /Users/charlesedge/Library/LaunchAgents/cx.pow.powd.plist *** Installing system configuration files as root... Password: /Library/LaunchDaemons/cx.pow.firewall.plist /etc/resolver/dev *** Starting the Pow server... *** Performing self-test... *** Installed For troubleshooting instructions, please see the Pow wiki: https://github.com/basecamp/pow/wiki/Troubleshooting To uninstall Pow, `curl get.pow.cx/uninstall.sh | sh` To install an app into Pow, create a symlink to it using ln (assuming ~/.pow is your current working directory): ln -s /path/to/myapp Then just open the url, assuming my app is kryptedapp.com: open http://kryptedapp.com Pow can also use ~/Library/LaunchAgents/cx.pow.powd.plist to port proxy. This allows you to redirect different apps to different ports. When pow boots, it runs .powconfig, so there’s a lot you can do there, like export, etc. Once you’re done testing out pow, if you don’t decide it’s awesome, remove it with the following command: curl get.pow.cx/uninstall.sh | sh

Microsoft Azure is Microsoft’s cloud services. Azure can host virtual machines and act as a location to store files. However, Azure can do much more as well, providing an Active Directory instance, provide SQL database access, work with hosted Visual Studio, host web sites or provide BizTalk services. All of these can be managed at https://manage.windowsazure.com. windows_azure_logo6 You can also manage Windows Azure from the command line on Linux, Windows or Mac. To download command line tools, visit http://www.windowsazure.com/en-us/downloads/#cmd-line-tools. Once downloaded, run the package installer. Screen Shot 2013-11-29 at 10.51.01 PMWhen the package is finished installing, visit /usr/local/bin where you’ll find the azure binary. Once installed, you’ll need to configure your account from the windowsazure.com site to work with your computer. To do so, log into the windowsazure.com portal. Screen Shot 2013-12-01 at 8.25.57 PM Once logged in, open Terminal and then use the azure command along with the account option and the download verb: azure account download This account downloads the .publishsettings file for the account you’re logged in as in your browser. Once downloaded, run azure with the account option and the import verb, dragging the path to your .publishsettings file from https://manage.windowsazure.com/publishsettings/index?client=xplat: azure account import /Users/krypted/Downloads/WindowsAzure-credentials.publishsettings The account import then completes and your user is imported into azure. Once imported, run azure with the account option and then storage list: azure account storage list You might not have any storage configured yet, but at this point you should see the following to indicate that the account is working: info: No storage accounts defined info: account storage list command OK You can also run the azure command by itself to see some neat ascii-art (although the azure logo doesn’t really come through in this spiffy cut and paste job): info: _ _____ _ ___ ___________________ info:        /_\  |__ / | | | _ \ __| info: _ ___ / _ \__/ /| |_| |   / _|___ _ _ info: (___ /_/ \_\/___|\___/|_|_\___| _____) info: (_______ _ _) _ ______ _)_ _ info: (______________ _ ) (___ _ _) info: info: Windows Azure: Microsoft's Cloud Platform info: info: Tool version 0.7.4 help: help: Display help for a given command help: help [options] [command] help: help: Open the portal in a browser help: portal [options] help: help: Commands: help: account to manage your account information and publish settings help: config Commands to manage your local settings help: hdinsight Commands to manage your HDInsight accounts help: mobile Commands to manage your Mobile Services help: network Commands to manage your Networks help: sb Commands to manage your Service Bus configuration help: service Commands to manage your Cloud Services help: site Commands to manage your Web Sites help: sql Commands to manage your SQL Server accounts help: storage Commands to manage your Storage objects help: vm Commands to manage your Virtual Machines help: help: Options: help: -h, --help output usage information help: -v, --version output the application version Provided the account is working, you can then use the account, config, hdinsight, mobile, network, sb, service, site, sql, storage or vm options. Each of these can be invoked along with a -h option to show a help page. For example, to see a help page for service: azure service -h You can spin up resources including sites, storage containers and even virtual machines (although you might need to create templates for VMs first). As an example, let’s create a new site using the git template: azure site create --git Overall, there are a lot of options available in the azure command line interface. The web interface is very simple, with options in the command line interface mirroring the options in the web interface. Running and therefore scripting around these commands is straight forward. I wrote up some Amazon stuff previously at http://krypted.com/commands/amazon-s3cmd-commands, but the azure controls are really full featured and I’m really becoming a huge fan of the service itself the more I use it (which likely means I’ll post more articles on it soon).

Create a file called goodmorning.rb and paste the following into it: #!/usr/bin/env ruby puts 'Good Morning' Make the file executable for your user. Then run the file (let’s just say it’s on the desktop of a user named admin): /Users/admin/Desktop/goodmorning.rb That’s all for this morning…

I originally posted this at http://www.318.com/TechJournal So Ruby on Rails… What does this mean for me and what exactly is Ruby on Rails from a systems administration standpoint? Ruby on Rails was created by David Heinemeier Hansson from his work on Basecamp, a web-based project-management tool, by the company 37signals. Ruby on Rails was first released to the public in July 2004. Ruby on Rails is a web application framework designed to support the development of dynamic websites. To see some sites built using Ruby on Rails check out http://happycodr.com Ruby is an object-oriented program language that Rails is built on.  To access rails, you can use the rails command. The Ruby on Rails framework is built into Leopard Server and can be started up using the mongrel_rails start command. It can be stopped using the mongrel_rails command. Mongrel is a fast HTTP library and server for Ruby. Mongrel_rails is a command line tool that can be used to control the Mongrel webserver. Some options to the mongrel_rails command include the following: -d daemonize -p assign a custom port -a assign an address for the HTTP listener -l assign a log file to use -t customize the timeout variable -m use additional MIME types -r change the document root -B enable debugging -C use a configuration file -S define an additional config script -h access the help libraries -G generate a config file –user define who the server will run as –version get the version information for Mongrel But that’s not all you can do with mongrel_rails. The actual file is not compiled so you can read it in clear text and learn more about what it is doing behind the scenes. Just cd into the /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/ folder to find it. One item of note is the inclusion ofmongrel_rails_persist, a wrapper for mongrel_rails that allows admins to register the Mongrel Server with Bonjour and create a launchd plist to run Mongrel (/Library/LaunchAgents/com.apple.persist.portnnnn.mongrel_rails_server.plist). So let’s say that you have a Ruby application that lives at the following location /Library/WebServer/MyRubyApp. You can run the following command to launch it over port 8001 in a persistent manner: mongrel_rails_persist start -p 8001 -c /Library/WebServer/MyRubyApp To access it from a web browser you would enter the address http://servername.domainname.com:8001 From here you’ll be able to daemonize Mongrel and provide the Rails development framework to developers in your environment. There are already a lot of projects for using Ruby with FileMaker and other database systems, so keep an eye out for more information about this piece of Leopard Server!
