I like magic like that :) I want automation as much as possible. On Jul 28, 2011, at 9:16 PM, Sven Van Caekenberghe wrote:
How easy and how fast can you download, install and start an complete Pharo Core based HTTP Server on a bare Linux machine ?
It just takes OneCommandLine:
$ curl http://zn.stfx.eu/zn/pharo-server.sh | bash
In well under a minute (in 11 seconds below, actually), you can browse http://localhost:1701 and all this with way less than 20Mb being downloaded.
Mind you, this is quick hack, for some this will be old news, for others I hope this feels like magic.
Some notes:
- pharo-server.sh will download, install and start a Pharo Smalltalk HTTP server - this script needs bash, curl, tar, unzip, at least, and was only tested on Ubuntu - no special permissions needed, all files will reside in ~/pharo-server - you will probably have to allow 1701 as a TCP port in your firewall for external access - technically, the most interesting thing is the script called st-exec.sh - you have to trust me that the installer is well-behaved, or have a look yourself ;-)
Next is a terminal log of running this script, at the end there is a small benchmark showing what kind of performance you can expect from this setup (saving the best for last). The machine in question is an Amazon EC2 micro instance, the smallest, least powerful that you can get.
Enjoy,
Sven
