Building FlowVisor on Centos 6 - quick and dirty

I had the need to build a FlowVisor instance under CentOS.  Since nearly all of the docs I could find were for debian, I threw this together.  I utilized this GENI doc and the github docs as a simple reference.  This is the quick and dirty method I used: Install the prerequisites:``` sudo yum -y install ant eclipse java-1.6.0-openjdk.x86_64 git sudo yum -y groupinstall “Development Tools”

mkdir /services
cd /services
git clone git://github.com/OPENNETWORKINGLAB/flowvisor.git

Navigate, add user and install``` cd flowvisor adduser flowvisor sudo make fvuser=flowvisor fvgroup=flowvisor install

\[root@collector flowvisor\]# sudo make fvuser=flowvisor fvgroup=flowvisor install
ant
Buildfile: build.xml

init:
\[mkdir\] Created dir: /services/flowvisor/build
\[mkdir\] Created dir: /services/flowvisor/build.tests

compile:
\[javac\] Compiling 239 source files to /services/flowvisor/build
\[javac\] Note: /services/flowvisor/src/org/flowvisor/config/LoadConfig.java uses or overrides a deprecated API.
\[javac\] Note: Recompile with -Xlint:deprecation for details.

dist:
\[mkdir\] Created dir: /services/flowvisor/dist
\[jar\] Building jar: /services/flowvisor/dist/flowvisor.jar

This yields a "working" flow visor.

Lock it down with a password:
``````
yum -y install pwgen
test -f /etc/flowvisor.passwd || sudo sh -c 'pwgen -sB 24 > /etc/flowvisor.passwd'
service flowvisor restart
