(First of all, sorry for my english, its not my native language so you
can read some basic/strange language constructions here :)
Hi, I'm facing a problem with my Apache (1.3.33) setup, I expose the scenario:
One single machine is serving several domains (about 300 or so). One
of them has thousands of visits a day (95% of daily load) and the
other domains have very low traffic.
I use awstats to parse the access_log file and get visit stats on a
daily basis, but it's growing up a lot. I parse the logfile with
awstats_updateall, and what it does is just parse the same log again
and again for each domain (remember, about 300)
So, I have an access_log with 95% of hits for only one domain, and the
other 300 domains are parsing the same big BIG file to just get 10
hits or so. It is very inefficient, isn't it?
The current setup is with a VirtualDocumentRoot directive on server
environment, so all domains are treated the same way. And I'd like to
distinguish the main domain from the oters so parsing speeds up and
gets more effective:
Hits to main domain go to one access_log file
Hits to any other domain go to *one* single access_log file, so calls
to awstats are against this only logfile. This way I get smaller file
(and quicker to parse) for the 300 domains.
I got a working setup but I doutbt if it works because I configured it
properly, or is kind of "collateral" effect of apache conffile-parsing
(This is a local network machine, i didn't test it in production
environment :):
NameVirtualHost 192.168.0.150
UseCanonicalName Off
LogLevel debug
<VirtualHost 192.168.0.150>
VirtualDocumentRoot /var/www/sites/%-2.1/%-2.2/%-2.3/%-2.0.%-1/
DirectoryIndex index.php index.html
CustomLog /var/log/apache/webs_access_log vspecial
</VirtualHost>
<VirtualHost 192.168.0.150>
ServerName www.portal.com
ServerAlias portal.com
DocumentRoot /var/www/portal/
CustomLog /var/log/apache/access_log vspecial
DirectoryIndex index.html index.cgi index.pl index.php
</VirtualHost>
I deduced that, as I use the ServerName directive, it just matches the
second VirtualHost if the request is *only* to that name, and uses the
first one in all other cases. Is that correct? Is that setup OK, or is
it working accidentally??
I tried several combinations:
If I switch Vhosts definition order, it doesn't work.
If I use <VirtualHost www.abcd.com> in the first entry, it works also
for all domains (why? because it is the first one and therefore the
default?).
Could someone please throw some light? I've been searching for mass
virtual hosting with separate logs (not for ALL, but the setup I
exposed here) but didn't find nothing interesting, and I found Apache
documentation a little poor on that topic. Does anyone have a pointer
on how does apache treat internally all the vhosts thing?
Thanks in advance!
