CompatibleOne Cloud Broker Setup – CentOS

This article describes how CompatibleOne can be setup and executed within a locally-hosted CentOS x64 environment run under VMware Workstation.

Cloud Brokering

See the CompatibleOne site for details on how the authors solved cross-vendor cloud brokering in a completely opensource solution. We will use this for our testing.

Use Case: We want to take a hardened image running on an Amazon EC2 server and migrate it to Microsoft’s Azure Platform. This first article discusses the underlying setup for CompatibleOne. We verify using an OpenStack implementation running on the low-cost Digital Ocean cloud provider; we’ll get to EC2 and Azure in a future article.

OpenStack

The CompatibleOne documentation has a brief tutorial on OpenStack, so we have a separate article on OpenStack setup which you can review.

CompatibleOne Host Platform

CompatibleOne runs on various Linux distributions. You can get the CompatibleOne software from this link and the choices are CentOS, RedHat (RHEL), Fedor, Ubuntu, and Debian. We chose CentOS 6.5 x86_64.

Our preference is to install and run CompatibleOne locally so we can do offline testing. We first tried to get the package to build and install using Cygwin so we could run CompatibleOne on our local laptop but that failed. We ended up using VMware Workstation and downloading a minimal (“network”) 64-bit Centos 6.5 image so we could keep the footprint small.

  • Create the VMware Workstation image with CentOS and installed using normal selections.
  • yum update to get latest packages. The entire list is as follows:
    yum update
    yum install autoconf automake autotools
    yum install make gcc libtool
    yum install openssl uuid openssl-devel uuid-devel libuuid-devel
    yum install git wget
  • Create user c-one (“Compatible-One”) and grant sudo privileges.
  • CentOS 6 ships with Python 2.6.6 (with critical security patches). However, CompatibleOne wants Python2.7! Prepare yourself for this by following the steps at this blog article; for completeness here are the steps we used (as root):
    yum groupinstall "Development tools"
    yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
    
    # Python 2.7.6:
    wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
    tar xf Python-2.7.6.tar.xz
    cd Python-2.7.6
    ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
    make && make altinstall
  • Finally – for Python 2.7 above – do *not* forget to link it to a place where CompatibleOne will find it:
    ln -fs /usr/local/bin/python2.7 /usr/bin

CompatibleOne Install

CompatibleOne comes with a reasonably complete documentation guide and we chose to build from source. Follow these steps:

    Setup Folder. We used these commands logged-in as the c-one user:

    
    mkdir proj
    cd proj
    mkdir accords
    cd accords/
    git clone http://git.gitorious.ow2.org/ow2-compatibleone/accords-platform.git
  • Prepare for autogen.sh. There was a bug in testorga/Makefile.am which causes autogen.sh to fail. Open the file and replace orga_SOURCES with testorga_SOURCES. Then run the following:
    [c-one@CompatibleOne accords-platform]$ ./autogen.sh
    Clean autogen generated files
    libtoolize: putting auxiliary files in `.'.
    libtoolize: copying file `./ltmain.sh'
    configure.ac:13: installing `./config.guess'
    configure.ac:13: installing `./config.sub'
    configure.ac:19: installing `./install-sh'
    configure.ac:19: installing `./missing'
    azprocci/Makefile.am: installing `./depcomp'
  • Configure the system. The CompatibleOne instructions specify to run ./configure at this point. Run ./configure:
    [c-one@CompatibleOne accords-platform]$ ./configure
    checking build system type... x86_64-unknown-linux-gnu
    checking host system type... x86_64-unknown-linux-gnu
    [...output cut...]
    config.status: executing libtool commands

        - coxml                    : yes
    [...output cut...]
        - testsuite                : no
        - pyaccords                : no
  • Build the system. This took a while on our box because we had to “discover” lots of the errors that we documented above.
    [c-one@CompatibleOne accords-platform]$ make
    Making all in scripts
    make[1]: Entering directory `/home/c-one/proj/accords/accords-platform/scripts'
    rm -f accords accords.tmp

    make[1]: Nothing to be done for `all-am'.
    make[1]: Leaving directory `/home/c-one/proj/accords/accords-platform'
  • Finalize build. We installed the built software using sudo which we *presume* is correct!
    
    sudo make install
    sudo ldconfig

CompatibleOne Configuration and First-Time Start

Once built and installed, configure CompatibleOne. This is not that bad; you basically create a configuration folder and provision all of the CompatibleOne configuration files within it. For our example, we had a dedicated user c-one so we used /home/c-one/small-accords as our starting point. Here are the set of steps:

cd /home/c-one
mkdir small-accords
cd small-accords
ACCORD_PLATFORM=/home/c-one/proj/accords/accords-platform
cp $ACCORD_PLATFORM/scripts/accords.ini .
cp $ACCORD_PLATFORM/scripts/cords_user.xml .
cp $ACCORD_PLATFORM/manifests/cords_price.xml .
cp $ACCORD_PLATFORM/scripts/style.css .
cp $ACCORD_PLATFORM/scripts/openssl.cnf .
cp $ACCORD_PLATFORM/coips.xml .
cp $ACCORD_PLATFORM/accounts.xml .
cp $ACCORD_PLATFORM/metrics.xml .
cp $ACCORD_PLATFORM/Certificates.crt .

The above prepares CompatibleOne for configuration, here goes!

[c-one@CompatibleOne small-accords]$ accords-config

Creating Accords Port Configuration : ports.xml
Creating Accords Nagios Configuration :
Creating Accords Global Configuration File: accords.xml
nagios is not required

Starting is easy; just run co-start (which is auto-installed in /usr/local/bin). For our first run we will see a lot of output, summarized below:

[c-one@CompatibleOne small-accords]$ co-start

Next, use the co-check script, which appears to be deprecated in the latest CompatibleOne release. At least, this script is not directly executable as installed by make install. But it can be run as follows:

[c-one@CompatibleOne bin]$ sh co-check

-- Verification Terminated --

All appears normal, or at least it's all "OK", right?

Finally, we can stop the system as we have fully built and configured it.

[c-one@CompatibleOne bin]$ co-stop

Other than the spurious-looking kill error above, it all looks good. We have successfully deployed CompatibleOne. Great Job!

Now what?

For normal operations, because we built from source you actually have to login as c-one and run co-start from the $HOME/small-accords folder. We may document how to create the /etc/init.d entry in another post, but it would basically do exactly that...run as c-one user and use the co-XXX functions to support start, stop, status, and so on.

In the next post we'll look at getting our shiny new CompatibleOne deployment running on a public cloud service provider.

Until then, Happy Computing!
