Too many people suggested that we plunge the syslog section because of
its slowness and unreliability. You should use log_spread instead if you
need to collect logs from many machines.
Since this section ss probably going away, here it is:
The syslog solution can be implemented using the following
configuration:
LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog "| /usr/local/apache/bin/syslogger.pl hostnameX" common
where a simple I<syslogger.pl> can look like this:
syslogger.pl
------------
#!/usr/bin/perl
use Sys::Syslog qw(:DEFAULT setlogsock);
my $hostname = shift || 'localhost';
my $priority = 'ndelay'; # open the connection immediately
my $facility = 'local0'; # one of local0..local7
my $priority = 'info'; # debug|info|notice|warning|err...
setlogsock 'unix';
openlog $hostname, $priority, $facility;
while (<>) {
chomp;
syslog $priority, $_;
}
closelog;
The syslog utility needs to know the facility to work with and the
logging level. We will use C<local0>, one of the special logging
facilities reserved for local usage (eight local facilities are
available: local0 to local7). We will use the C<info> priority level
(again one of eight possible levels: I<debug>, I<info>, I<notice>,
I<warning>, I<err>, I<crit>, I<alert>, I<emerg>).
Now make the syslog utility on the master machine (where all logs are
to be stored) log all messages coming from facility C<local0> with
logging level C<info> to a file of our choice. This is achieved by
editing the I</etc/syslog.conf> file. For example:
local0.info /var/log/web/access_log
All other machines forward their logs from facility C<local0> to the
central machine, therefore on all but the master machine we add the
forwarding directive to the I</etc/syslog.conf> file (assuming that
the master machine's hostname is C<masterhost>):
local0.info @masterhost
We must restart the syslogd(8) daemon or send it the C<-HUP> kill
signal for the changes to take effect before the logger can be used.
