Proxying from apache2 to application server (eg tomcat, jetty)

It is often convenient to proxy an application server, such as Jetty or Tomcat, as these tend to be mounted on ports other than port 80. The following steps worked in an Ubuntu setup.

Enable mod_proxy
a2enmod proxy
a2enmod proxy_http

Edit sites-enabled/default to add your proxying rule, eg:
ProxyPass /alfresco http://localhost:8080/alfresco
ProxyPassReverse /alfresco http://localhost:8080/alfresco
<Proxy http://localhost:8080/alfresco*>
Order deny,allow
Allow from all

/etc/init.d/apache2 restart

You should now see your application server content on your default url ie http://localhost/alfresco will contain the same content as

Alfresco setup

Alfresco is AMAZING - it does not follow the Unix way, or even the Java way, but rather the bloatware way. This is a very bad smell (as is their constant pimping of the paid version).

Alfresco comes with ITS OWN COPY of Java, MySQL and Tomcat.
As I have copies of all these systems on my own box I have chosen to insulate my system and to play fair with Alfreco, and install on a fresh Ubuntu VirtualBox VM, with nothing other than OpenSSH installed.

VM Setup: I also enabled the VirtualBox Guest Additions, on my MacBookPro host, and found that the default bidirectional Copy/Paste functionality did not work.
Stop the VM and change Settings>>Advanced Shared Clipboards to Host To Guest

This vm (called alfresco) is on a virtual network, setup with help from Mr Sysadmin:

Add a Host only network in virtualbox >> preferences >> network

Add an adapter2 to vm >> settings >> network
attached to Host-only adapter

Add to /etc/hosts on host machine alfresco

On vm add to /etc/network/interfaces
auto eth1
iface eth1 inet static
/etc/init.d/networking restart

Install alfresco (NOTE The x32 versions also works)
sudo su
chmod u+x alfresco-community-3.4.d-installer-linux-x64.bin

Take defaults, specify a password for mysql root and Alfresco admin.
/etc/init.d/alfresco start

Now the url http://alfresco:8080/alfresco/ should work.

Dual repositories: Subversion and Git

Git and SVN

I have not got a completely pain free git/svn integration,
this seems to be because casutils started life as a git project.

Install git svn integration
sudo apt-get install git-core git-svn

I have two checkouts: local/casutils and workspace/casutils
workspace/casutils was created in the normal way with
git init casutils
local/casutils was created with
git svn clone
I work in workspace/casutils, when all is committed and pushed to master I switch to local/casutils
git pull -s recursive -Xtheirs ../../workspace/casutils
git svn dcommit

this pushes the changes, with their git commit messages, to svn.
