[users@httpd] rotating log files
Hi guys,
I am quite new to the HTTP server. I was making some efforts to
understand how to do log files rotation. I read the documentation on
rotating log files.
There is an example of doing it this way
mv access_log access_log.old
mv error_log error_log.old
apachectl graceful
sleep 600
gzip access_log.old error_log.old
Do I write this in the configuration file or is it a separate script I
have to write?
Regards,
david

You can send a HUP signal to apache which will restart writing the files...
if you use logrotate something like:
/var/log/httpd/access.log
{
sharedscripts
size=100M
prerotate
# any prerotate here
# we run a stat update here...
endscript
postrotate
kill -HUP `cat /var/run/httpd.pid`
endscript
}
adjust to your taste...

That's what the "apachectl graceful" does.

I was curious, doesn't apache actively write to the log files? So do we
need to stop apache before, say move the files? (Stop the network when
we move the files, may be?)
Would the graceful start create new access and error log files, since
they were non existant after the move?
Thanks,

It would be a separate shell script that you'd run every night or on
Sunday or whatever...
If you want something where you can save logs for late processing for
a greater length of time:
dt=$(date '+%Y%m%d')
mv access_log access_log.$dt
mv error_log error_log.$dt
apachectl graceful
sleep 600
gzip access_log.$dt error_log.$dt
This way, you'll end up with date stamped log files.

Check cronolog at: http://www.cronolog.org/
cronolog is a simple filter program that reads log file entries from
standard input and writes each entry to the output file specified by a
filename template and the current date and time. When the expanded
filename changes, the current file is closed and a new one opened.
cronolog is intended to be used in conjunction with a Web server, such
as Apache, to split the access log into daily or monthly logs. For
example the Apache configuration directives:
TransferLog "|/usr/sbin/cronolog /web/logs/%Y/%m/%d/access.log"
ErrorLog "|/usr/sbin/cronolog /web/logs/%Y/%m/%d/errors.log"
would instruct Apache to pipe its access and error log messages into
separate copies of cronolog, which would create new log files each day
in a directory hierarchy structured by date, i.e. on 31 December 2002
messages would be written to
/web/logs/2002/12/31/access.log
/web/logs/2002/12/31/errors.log
after midnight the files
/web/logs/2003/01/01/access.log
/web/logs/2003/01/01/errors.log
would be used, with the directories 2003, 2003/01 and 2003/01/01 being
created if they did not already exist. More detail to come...
