I created a CentOS 6.5 Droplet on Digital Ocean with 8GB RAM (you'll need at least 4 for the Java portion of the build), feel free to use any other CentOS 6.5 environment that you can have root on.
First, Mesos 0.21.0+ requires subversion 1.8+ devel package which is not available by default by yum. Add a repo that has subversion-devel 1.8 available, i.e:
Add new repo /etc/yum.repos.d/wandisco-svn.repo, with:
[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/6/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0
Now install a bunch of packages:
yum -y update
yum groupinstall -y "Development Tools"
yum install -y python-devel java-1.7.0-openjdk-devel zlib-devel libcurl-devel openssl-devel cyrus-sasl-devel cyrus-sasl-md5 apr-devel subversion-devel wget apr-util-devel
Install Maven (used to build Mesos):
cd ~
wget http://mirror.nexcess.net/apache/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.tar.gz
tar -zxf apache-maven-3.0.5-bin.tar.gz -C /opt/
ln -s /opt/apache-maven-3.0.5/bin/mvn /usr/bin/mvn
Install Gradle (used to build Aurora):
cd ~
wget https://services.gradle.org/distributions/gradle-2.2.1-all.zip
unzip gradle-2.2.1-all.zip
Install Python 2.7 (required by Aurora):
There's various ways to install Python 2.7, the simplest way I found to install it and to make sure it was being used when building Mesos was to do the following (thanks to http://bicofino.io/blog/2014/01/16/installing-python-2-dot-7-6-on-centos-6-dot-5/#comment-1575167554):
yum -y install centos-release-SCL
yum -y install python27
# drop into a new shell where python 2.7 is configured for the environment
scl enable python27 bash
Get the latest Aurora:
cd ~
wget https://github.com/apache/incubator-aurora/archive/master.zip -O aurora-master.zip
unzip aurora-master.zip
AURORA_HOME=/root/incubator-aurora-master
This step will take a while (15 - 20min, something like that):
cd ~
mesos_version=0.21.1
MESOS_BASEURL=https://archive.apache.org/dist/mesos
wget --progress=dot "$MESOS_BASEURL/$mesos_version/mesos-${mesos_version}.tar.gz"
tar zxvf mesos-${mesos_version}.tar.gz
cd mesos-$mesos_version
mkdir build
cd build
../configure
make
Copy the python egg files into a third_party directory in the Aurora directory:
mkdir $AURORA_HOME/third_party
find . -name '*.egg' -exec cp {} $AURORA_HOME/third_party \;
Build the client and admin client:
cd $AURORA_HOME
./pants binary src/main/python/apache/aurora/client/cli:aurora
./pants binary src/main/python/apache/aurora/admin:aurora_admin
Build the executors:
./pants binary src/main/python/apache/aurora/executor/bin:gc_executor
./pants binary src/main/python/apache/aurora/executor/bin:thermos_executor
./pants binary src/main/python/apache/thermos/bin:thermos_runner
# package runner within executor
python2.7 << EOF
import contextlib
import zipfile
with contextlib.closing(zipfile.ZipFile('dist/thermos_executor.pex', 'a')) as zf:
zf.writestr('apache/aurora/executor/resources/__init__.py', '')
zf.write('dist/thermos_runner.pex', 'apache/aurora/executor/resources/thermos_runner.pex')
EOF
Build the observer:
./pants binary src/main/python/apache/thermos/observer/bin:thermos_observer
Build the scheduler:
/root/gradle-2.2.1/bin/gradle distTar
At this point you should have a bunch of stuff under the dist directory:
[root@aurora incubator-aurora-0.7.1-master]# ll dist/
total 64520
-rwxr-xr-x 1 root root 2254309 Feb 24 05:35 aurora_admin.pex
-rwxr-xr-x 1 root root 2303226 Feb 24 05:35 aurora.pex

-rwxr-xr-x 1 root root 582026 Feb 24 06:10 thermos_runner.pex
drwxr-xr-x 4 root root 4096 Feb 24 06:16 tmp
You'll want dist/*.pex and dist/distributions/aurora-scheduler-0.7.1-SNAPSHOT.tar.
You can look at the upstart conf files to start the scheduler and observer(https://github.com/apache/incubator-aurora/blob/master/examples/vagrant/upstart/aurora-thermos-observer.conf)
The Aurora folks recommend building your own Mesos egg files, instead of using their prebuilt files. I followed the instructions here, which are included in the steps above.
