When using windows I would use "The Uniform Server" which would allow me to create folders and install an instance of TUS into each folder and run each instance of TUS separately*, where each had its own configuration settings for the programs/services and website running from the folder TUS was installed to. Its great for USB sticks since it can run independently of the OS and therefor doesn't need to be installed as such. It is just run. Is there such an app for linux?
*Only one instance of TUS and the programs running from it (Apache, mysql) can be run at anyone time afaik.
