Some time ago I moved from servelocity to bytemark for my hosting. I was
having problems with running out of memory on a regular basis. The
main problems was that as it was a virtual server I could never
tell as it was always using all of it’s 24Gb of RAM! So I
moved to bytemark who use user-mode-linux and
are soon to move to xen. I now
have a little server with 80Mb of my own RAM. Now this is quite
small for all the rubbish that I want to run but at least I can see
what is going on and when it starts to swap I can do something
about it rather than processes just dying with a “Out of
memory error”. I have been running apace2 for my web serving
for a while and I have been trying to limit its memory usage but
never really been happy with a few processes each taking up 16Mb of
my VM (I know some of that is shared but it’s still quite a
lot)
The move to lighty was
pretty simple, I installed it at home on my server dug about a bit,
enabled the cgi and ssl modules and ran it up. Less than 2.5Mb! I
have setup virtual hosts, ssl, and php support and it’s still
running really sweet.
Next I just needed to setup the redirects for wordpress which is
really the reason for this entry I added the following:
$HTTP["url"] =~ "^/ramble/" {
server.error-handler-404 = "/ramble/index.php?error=404"
}
Looks like it works! So I copied the configs over to my virtual
server and stopped apache and started up lighttpd and hay presto I
now have a few Mb of free RAM (up to 30Mb when it’s quiet)
and 30Mb in use for caching so things are starting to fly now!
Now lets see how stable it is, as apache for all it’s sins
has been rock solid.
