Net::SCP is a pure-Ruby implementation of the SCP protocol. This operates over SSH (and requires the Net::SSH library), and allows files and directory trees to copied to and from a remote server.

This solution lies somewhere between manually uploading and fully automation using Capistrano or Vlad.

Drupal rocks for some things, its deployment sucks! As I automate my drupal workflows better, I should post them one by one.

Following is the my bash script recipe, for installing drupal, checking it into a git repository and replicating it remotely.

The second piece of puzzle should be automating MySQL backup and deployment using either Capistrano or Vlad.

I installed Scala in /usr/local , the reason for which can be found here.

Prerequisite

Before starting installation, you will need **:

1. Mac OS X 10.6 Snow Leopard
2. The latest Xcode Tools (from the Snow Leopard DVD or downloaded from Apple — the 10.5 version won’t work)
3. Confidence running UNIX commands using the Terminal

Step 1: The PATH

Launch Terminal from /Applications/Utilities folder.

First lets set the PATH variable using a text editor. I use Textmate (hence the mate command). You can use Textmate, Smultron or vim.

mate ~/.bash_profile

At the end of this file add(even if it is blank)

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/scala/scala-2.7.5.final/bin:$PATH"

Save and close the file. Close the Terminal. On restarting the terminal, enter following command:

echo $PATH

We should be able to see /usr/local/scala/scala-2.7.5.final/bin as one of the paths. Note: If we were compiling scala, we would prefer its binaries to be at /usr/local/bin/scala. However we are taking the easier route.

Step 2: Download Scala

I keep all my software installers that I install away from Application folder, in a folder in home directory.

Make a new folder:

mkdir ~/SourceFolder
cd ~/SourceFolder

Download scala IzPack Installer:

curl -O http://www.scala-lang.org/downloads/distrib/files/scala-2.7.5.final-installer.jar

Step 3: Install

The installer needs administrator permission. Hence install by double click would not complete due to permissions issue.

On the Terminal:

sudo java -jar scala-2.7.5.final-installer.jar

Type in the password when prompted. Installer GUI would start

Choose language.

Goto next.

Read and accept the license.

By default, the installer will install in /usr/local/. However choose /usr/local/scala/, otherwise the installer tends to overwrite /usr/local.

Scala is installer.

To verify, we’ll run Scala interpreter:

scala

On my machine, it shows:

Welcome to Scala version 2.7.5.final (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_15).
Type in expressions to have them evaluated.
Type :help for more information.

scala>

Type :quit to exit from the interpreter.

Scala is installed on Snow Leopard.

Before moving to new system (where I enforce quotas on all home folders), I had portable home directories for all the users on my shared server storage. The old setup did not strictly apply the quota limits on all users. Some of the users had large home folders and a couple of them logging on different systems, would fill up the whole hard disk on that system.

To find out how much space each user was using on the server, I ran the following command in their home directory.

$ du -chd -1 > $HOME/user_space_report.txt

Simple.

Globally ignore .DS/_Store

echo ".DS_Store" >> ~/.gitignore
git config --global core.excludesfile ~/.gitignore

Information about me and my email goes here.

git config --global user.name "My name"
git config --global user.email me@olemiss.edu

I love colors

git config --global color.branch auto
git config --global color.diff auto
git config --global color.interactive auto
git config --global color.status auto

And I love TextMate

git config --global core.editor "mate -w"

Coming from Linux background, while working on OS X shell, I still cannot abandon my old Linux habits. A common one is trying to use wget instead of curl for downloading stuff.

Just out just curiosity, I was wondering why OS X supports curl, but no wget in the OS.

I came across this interesting page doing comparison of the two.

I work with Ruby on Leopard and and I need RMagick.

If you are a programmer and don’t know what RMagick is, you should know how code can melt your picture into art in Ruby:).

Thanks to Onrails.org for the starting script, I have removed some cruft and added some spice.

RMagicK install tastes good with freshly brewed UpTown coffee.

#!/bin/sh
mkdir -p ~/Scripts
cd ~/Scripts
if [ -d ImageMagickInstall ]
then
# remove old ImageMagickInstall directory if it exists 
   rm -rf ImageMagickInstall
fi

As soon as I pushed my project directory to my remote OS X Tiger server, I got the following error.

    bash: line 1: git-receive-pack: command not found
    fatal: The remote end hung up unexpectedly

Google comes to rescue.

    Many installations of sshd do not invoke your shell as the login shell when you directly run programs; what this means is that if your login shell is bash, only .bashrc is read and not .bash_profile. As a workaround, make sure .bashrc sets up $PATH so that you can run git-receive-pack program.

Running following two lines solved the problem.

echo export PATH=/usr/local/bin:$PATH >> ~/.bashrc
source ~/.bashrc

Although it is one of the first chapters one read when starting with Linux/Unix, it is always confusing where should we put what when it comes to installing stuff on Linux/OS X computers.

I found a detailed reference Filesystem Hierarchy standard website.

It is also worth knowing, why is it important to store any new customized apps in /usr/local.

Steps I took to install Git on OS X Tiger server are as follows (Thanks to LarrytheLiquid):

cd /usr/local/src

Next lets install an XML parser dependency, Git, and it’s man pages:

curl -O http://surfnet.dl.sourceforge.net/sourceforge/expat/expat-2.0.1.tar.gz
tar xvzf expat-2.0.1.tar.gz
cd expat-2.0.1
./configure --prefix=/usr/local
make
sudo make install
cd..

curl -O http://kernel.org/pub/software/scm/git/git-1.5.3.7.tar.gz
tar xvzf git-1.5.3.7.tar.gz
cd git-1.5.3.7
./configure --prefix=/usr/local
make
sudo make install
cd ..

curl -O http://www.kernel.org/pub/software/scm/git/git-manpages-1.5.3.7.tar.bz2
sudo tar xjv -C /usr/local/man -f git-manpages-1.5.3.7.tar.bz2

Add the following environment variable to whatever file your shell uses (.bash_profile for BASH):

export MANPATH="/usr/local/man:$MANPATH"

One last line to add

export PATH="/usr/local/bin:$PATH"

Git Installed. Check installed version.

git --version
