When I sign up for Linode, it will probably give me options for the type of
setup. Which one should I choose?
Arch Linux 2012.10
CentOS 6.2
Debian 6
Fedora 17
Gentoo
openSUSE 12.1
Slackware 13.37
Ubuntu 10.04 LTS
Ubuntu 11.10
Ubuntu 12.04 LTS
Ubuntu 12.10
Also is there anything else I should take care of during the sign-up
process?
thanks

should have no issue on a $20/mo 512MB Linode provided you're running a
modern PHP stack.

would that trigger a

my present hosting company
and
it stresses me out. That's how I was kicked
out - too many CPU alerts. My
setup at that time had no speed/cache optimization. Maybe the new Linode
setup would be so fast that traffic spikes would not be a problem.
I just don't want any kind of resource usage alerts and yes, I know once
I
get more traffic like you do, I'll have to
upgrade. I can even get the
1GB
Linode later.
Once a link to the wiki was posted on the front page of Reddit and we had
lots of traffic and I had to take that page down for a short while
(redirected). Another time, a link was posted to a Facebook page which
had
20 or 60K likes and we were getting clicks like
crazy and I had to take
that page down too.
About this:

mediawiki
file
cache. If you're not getting the performance you want you could also run
Varnish or set up a separate Linode for memcached. You could also place
the
wiki behind Cloudflare if you're serving a
lot of media files on page, if
not I don't think it would be beneficial.
I'm not serving media files. Most stuff is regular wiki pages (most of
them
to logged out users, as is often the case) and
even graphics are rarely
used. I've heard of the NGINX recommendation before but I have no
experience with it. The price for the 512 package is definitely
attractive
and I can get it and play with the setup.
thanks

What can be done to optimize Squid for mediawiki and increase the hit
ratio? The RAM I have available is 1.3GB and I told Squid it can use
130MB

email me your Squid.conf (remove any sensitive
information) and I can
compare it with my setup. Or you could tell me the settings I should
change
or add.
thanks!
