If you'd like to run multiple server instances on the same machine, you can use some virtualization software such as VMWare Player.

Install The Player

If installing on a Debian/Ubuntu-based system, you may run into problems running the installer. Here's the workaround.

1. First, set your gcc compiler to match the one your system's kernel used.

cd /usr/bin; mv gcc gcc.ORIG; ln -s gcc-4.1 gcc

2. Next, install your kernel's header files, and symlink them to where the installer wants them:

apt-get install linux-headers-$(uname -r); \
cd /usr/src/; ln -s ln -s linux-headers-2.6.22-1-mepis-smp linux

3. Unpack the provided tar.gz, and run the installer:

cd /tmp/; tar xzf VMware-player-2.0.1-55017.i386.tar.gz; \
cd vmware-player-distrib; ./vmware-install.pl

Get An Image

Download a VMWare appliance from one of these places, then unpack it and start it up.

• VMWare Appliances Directory
• The Canned OS Project

Configure The Image

Now that you have a working linux image, you can start installing other software into it, and configuring the filesystem according to these instructions.

• Ubuntu/Debian Build Server Setup
• RedHat/Fedora Build Server Setup
