HOW TO get Apache to log to PostgreSQL
|
|
|
|
First, this is intended mostly as a starting point, an example of how to do it.
|
|
|
|
The file 'httpconf.txt' is commented and contains two example lines to make
|
|
this work, a custom log format, and a line that sends the log data to psql.
|
|
I think that the comments in this file should be sufficient.
|
|
|
|
The file 'apachelog.sql' is a little SQL to create the table and grant
|
|
permissions to it.
|
|
|
|
You must:
|
|
|
|
1. Already have 'nobody' (or what ever your web server runs as) as a valid
|
|
PostgreSQL user.
|
|
|
|
2. Create the database to hold the log, (example 'createdb www_log')
|
|
|
|
3. Edit the file 'apachelog.sql' and change the name of the table to what
|
|
ever you used in step 2. ALSO if need be, change the name 'nobody' in
|
|
the grant statement.
|
|
|
|
4. As an appropriate user (postgres is ok), do 'psql www_log < apachelog.sql'.
|
|
This should have created the table and granted access to it.
|
|
|
|
5. SAVE A COPY OF YOUR httpd.conf !!!
|
|
|
|
6. Edit httpd.conf, add the two lines in the example file as appropriate,
|
|
IN THE ORDER IN WHICH THEY APPEAR. This is simple for a single server,
|
|
but a little more complex for virtual hosts, but if you set up virtual
|
|
hosts, then you should know were to put these lines.
|
|
|
|
7. Down and restart your httpd. I do it on Red Hat 4.1 like this:
|
|
/etc/rc.d/init.d/httpd.init stop
|
|
then
|
|
/etc/rc.d/init.d/httpd.init start
|
|
OR I understand you can send it a signal 16 like 'kill -16 <pid>' and do it.
|
|
|
|
8. I should be working, query the web server about 30 or more times then look
|
|
in the db and see what you have, if nothing then query the web server
|
|
30 or 50 more time and then check. If still nothing, look in the server's
|
|
error log to see what is going on. But you should have data.
|
|
|
|
NOTES:
|
|
The log data is cached some where, and so will not appear INSTANTLY in the
|
|
database! I found that it took around 30 queries of the web server, then
|
|
many rows are written to the db at once.
|
|
|
|
ALSO, I leave it up to you to create any indexes on the table that you want.
|
|
|
|
The error log can (*I think*) also be sent to PostgreSQL in the same fashion.
|
|
|
|
At some point in the future, I will be writing some PHP to interface to this
|
|
and generate statistical type reports, so check my site once and a while if
|
|
you are interested it this.

Have fun ... and remember, this is mostly just intended as a stating point,
|
|
not as a finished idea.
