Codio is awesome. Coolio would have been a better name, but I guess that’s taken!
It’s free, but don’t let that fool you. What you get is a beautifully simple yet powerful IDE in your browser. It works great even on my tablet, so I can edit/update/deploy even on the road (or on the couch half asleep, and here’s where git comes in handy!). It supports github out of the box. And has a cool terminal with SSH and everything. Yay!
Now if that was not awesome enough, these guys went out of their way and added an even cooler feature:
Every project gets its own Box: an instantly available server-side development environment with full terminal access.
So you get to do it all without leaving their site. I wanted to try playing with a pet project I’m working on using django. It was pretty easy to get it all setup (especially that the code was on github, but you could as simply upload the code).
Here’s a step by step tutorial to get django up and running on codio.
Open a terminal:
Tools > Terminal
I’m using MySQL, so:
parts install mysql
parts mysql start
mysqladmin -u root password StrongPassword
mysql -u root -pStrongPassword
mysq> create database dbname;
mysql> grant all privileges on dbname.* to 'dbuser'@'localhost' identified by 'dbpasswd';
mysql> flush privileges;
Also make sure to install python using the ‘parts’ command:
parts install python2
(see the related issue on github.com: https://github.com/codio/boxparts/issues/80)
Create the requirements.txt file if you don’t have that already. Hint: run ‘pip freeze > requirements.txt’ to save those. So in requirements.txt:
Run the following in the codio.com terminal:
parts install pip
pip install -r requirements.txt
Upload the django project, or import it from GitHub then:
python manage.py syncdb
python manage.py runserver 0.0.0.0:8009
I still need to get it running through apache.
I’ll get on that later tonight.
parts install apache2_mod_wsgi # also installs apache2 and apr_util
============ apache2 ============
To start the Apache server:
$ parts start apache2
To stop the Apache server:
$ parts stop apache2
Apache config is located at:
Default document root is located at:
============ apache2_mod_wsgi ============
If Apache2 httpd is already running, you will need to restart it:
$ parts restart apache2
Default configuration for wsgi is:
WSGIScriptAlias / /home/codio/workspace
You can change default in /home/codio/.parts/etc/apache2/config/wsgi.conf file
So I changed the file in /home/codio/.parts/etc/apache2/config/wsgi.conf to:
LoadModule wsgi_module /home/codio/.parts/packages/apache2_mod_wsgi/3.4/mod_wsgi.so
WSGIScriptAlias / /home/codio/workspace/conf/wsgi.py # <-- this is where I put my wsgi.py file
Require all granted
Then start apache, and visit your site at http://UNIQUE-NAME.codio.io:3000/:
parts start apache2
You will probably see a ‘500 Internal Server Error’ message. So tail the apache ErrorLog file in the terminal to see what went wrong:
tail -f /home/codio/.parts/var/apache2/log/error_log
Here’s what I see (and I haven’t figured the fix yet):
 mod_wsgi (pid=912): Target WSGI script '/home/codio/workspace/conf/wsgi.py' cannot be loaded as Python module.
 mod_wsgi (pid=912): Exception occurred processing WSGI script '/home/codio/workspace/conf/wsgi.py'.

… issue fixed by installing python using the ‘parts’ command above
