Tiny Core

Thursday, 20th Dec 2012  Posted @ 15:19

I have been playing around with Tiny Core and Micro Core Linux for quite a while now but have yet to do anything particularly useful with it.

Well now I have :)

I have created a minimal VMWare image capable of being a complete (and useable) webserver - a LEMP server - its only a 60mb download and the links are further down this post.

Tech specs:

1 vcpu
256mb RAM
1Gb hard drive (split 256mb swap, the rest as storage)

Software installed:
Core 4.7.1
openSSH 6.0p1
nGinx 1.0.12
PHP 5.3.8 (fast_cgi)
mySQL 5.5.17
along with all dependencies.

There is persistence for all the config files for the above and the mySQL databases. to be sure, issue sudo filetool.sh -b if you make any changes to anything.


It has been tested under ESXi 4.1 and also VM Player with no problems (apart from maybe complaints about floppy drives!)

Once its up and running and seen a few iterations from ApacheBench, htop shows this:picture

I am regularly seeing it capable of processing over 1000 requests a second (hitting a page that calls the phpinfo() function) running on a single 2.3Ghz vcpu

Next up, I will be attempting to create a minimal load balancer/reverse proxy (using the likes of Pen and Varnish) appliance and also a Lightttpd version of this appliance.

Anyway, you can find the zip file here or here. if you find it useful or have any questions, leave a comment.
