Magento 1.5.0.1 Installer

1. Creates a .pearrc file in your home directory.
2. Sets the download_dir, cache_dir, and temp_dir to folders within your /home/user/pear directory
3. Sets the PHP_PEAR_PHP_BIN variables by adding “export PHP_PEAR_PHP_BIN=/usr/local/php5/bin/php” to your .bash_profile
4. Modifies your PATH variable by adding “export PATH=/home/user/pear:/usr/local/php5/bin:$PATH” to your .bash_profile. This change also sets the PHP5 binary as the default for your shell.

Next time you call pear you’ll be using your custom settings and when you attempt to install any modules it will be done within your home directory. Now in order to use these PEAR modules in your application you will need to add the following to your app:

$pear_user_config = '/home/user/.pearrc';
set_include_path('.' . PATH_SEPERATOR . '/home/user/pear/php' . PATH_SEPERATOR . get_include_path());

Make sure to update “user” in the path to the actual user you are using and you’ll be set.

Download and Execute the Script

Just execute the following in a shell session:

wget http://files.gimmesoda.com/dreamhost/install_pear.sh; chmod 0744 install_pear.sh; ./install_pear.sh;

You can download and review the shell script from here, just open it up in a text editor of your choice.

ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key

So apparently that command is magical! Alright, so it’s not magical but it was able to delete over 200,000 spam messages from a users Maildir/ when the rm command failed. “-bash: /bin/rm: Argument list too long”, it complained! So asking around I found out about that beauty of a command and how rm can only take a certain amount of arguments before failing.

Nice to know, as my journey of learning more about Debian Linux (and Linux in general) continues.
