Another option is to use the sysutils/cronolog port. Configure it in
httpd.conf, with ErrorLog and CustomLog directives similar to the
following:
----
ErrorLog "|/usr/local/sbin/cronolog --symlink=/var/log/httpd/error_log /var/log/httpd/error_log_%y%m%d"
CustomLog "|/usr/local/sbin/cronolog --symlink=/var/log/httpd/access_log /var/log/httpd/access_log_%y%m%d" combined
----
cronolog will rotate logs automatically each day. From the cronlog man page:
Before writing a message cronolog checks the time to see whether the
current log file is still valid and if not it closes the current file,
expands the template using the current date and time to generate a new
file name, opens the new file (creating missing directories on the path
of the new log file as needed unless the program is compiled with
-DDONT_CREATE_SUBDIRS) and calculates the time at which the new file
will become invalid.
See the man page for further details.
I've been using it for awhile on my public web server. Seems to work just fine.
