Since Ubuntu is released every six months, I’ve compiled a set of instructions/shell commands to get my development environment up ASAP. This one references packages applicable to 11.10 (Oneiric Ocelot). If you use a different one, your mileage will differ!

Package management
Oneiric ships with — in my opinion only, of course — too many packages, so customize (or completely exclude) the apt-get remove, apt-get install sections as required.
sudo apt-get remove aisleriot quadrapassel gbrainy gnome-games-common gnome-mahjongg libreoffice-* gnome-sudoku gnomine -y; \
sudo apt-get autoremove -y; \
sudo apt-get update; \
sudo apt-get upgrade -y; \

- Paste the copied public key into the “Public keys” section of your git repository provider.
- ~/.gitconfig creates Subversion-like aliases.
Apache
The recommended method to serve PHP pages is via mod_userdir; i.e. a public_html/ from the user’s home directory; e.g. /home/kzhiwei/public_html/. The following commands enable mod_rewrite and mod_userdir.
sudo a2enmod rewrite; \
sudo a2enmod userdir;
- Define ServerName in /etc/apache2/httpd.conf; e.g. “localhost”.
- Update AllowOverride in /etc/apache/mods-available/userdir.conf to “AllowOverride All”, so URL rewriting, .htaccess files work correctly.
- If using CakePHP with mod_rewrite, the default .htaccess files will not working correctly. Use RewriteBase to adjust accordingly; e.g. for http://localhost/~kzhiwei/github.com/kzhiwei/sandbox/ to work correctly; e.g.
- /.htaccess: RewriteBase /~kzhiwei/github.com/kzhiwei/sandbox/
- /app/.htaccess: RewriteBase /~kzhiwei/github.com/kzhiwei/sandbox/app/
- /app/webroot/.htaccess: RewriteBase /~kzhiwei/github.com/kzhiwei/sandbox/app/webroot/
- Update /etc/apache2/mods-available/php5.conf by commenting “php_admin_value engine Off”, so PHP in user-directories work correctly.
- Issue ‘sudo service apache2 restart’ when done.

Command-T plugin for Vim
Command-T is the one plugin I use. For working with large code bases with multiple files, it helps me open multiple buffers quickly, with a couple of keystrokes. My explanation doesn’t do it much justice, you have to give it a try yourself. If it’s the only new thing you try in 2012, this is it!
wget http://www.vim.org/scripts/download_script.php?src_id=15560 -O ~/command-t.vba; \
vim ~/command-t.vba;
Command-T is distributed as a “vimball” which means that it can be installed
by opening it in Vim and then sourcing it.
:e command-t.vba
:so %
Next the C extension is built from the shell:
cd ~/.vim/ruby/command-t/; \
ruby extconf.rb; \
make;
Assuming make is successfully, the next time you open Vim you’ll be able to use the Leader key — defaults to backslash (/) — to summon Command-T. Thereafter, inputting the path/name of the file you’re interested in, then hit Enter to open.
Oracle Express Edition (XE)
wget http://oss.oracle.com/debian/dists/unstable/non-free/binary-i386/oracle-xe-universal_10.2.0.1-1.1_i386.deb; \
sudo dpkg -i oracle-xe-universal_10.2.0.1-1.1_i386.deb; \
sudo /etc/init.d/oracle-xe configure; \
. /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle_env.sh; \
sudo pecl install oci8; \
sudo touch /etc/php5/conf.d/oci8.ini;
- When prompted to provide the path to the ORACLE_HOME directory, use ‘/usr/lib/oracle/xe/app/oracle/product/10.2.0/server’.
- Using oracle_env.sh to define Oracle-related environment variables mostly works correctly, except two naggy “[[: not found” errors. This can be resolved by editing lines 108, 110 of /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh and removing the extra set of brackets.
- Add “extension=oci8.so” to /etc/php5/conf.d/oci8.ini.
- Add “export LD_LIBRARY_PATH=’/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib:’; export ORACLE_HOME=’/usr/lib/oracle/xe/app/oracle/product/10.2.0/server’” to /etc/apache2/envvars so that Oracle works correctly in PHP.
- In case “pecl install oci8″ fails, check if php5-dev, php-pear is installed.
