remote rsyslog client/server issue

Question

I only want rsyslog to send the logs to the centralized rsyslog server but it is sending them locally as well. This is for legal reasons, the servers will not have a logs directory, only the centralized rsyslog server will have logs.

I thought by using '&~' in the client's rsyslog.conf, it will send logs remotely only but I am wrong.

Here is the centralized rsyslog server config:

$ModLoad imuxsock # provides support for local system logging
$ModLoad imklog   # provides kernel logging support (previously done by rklogd)
$ModLoad immark   # provides --MARK-- message capability

module(load="imudp") # needs to be done just once
input(type="imudp" port="514")

$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

$klogConsoleLogLevel 3

$FileOwner root
$FileGroup root
$FileCreateMode 0640

Answer 1

You probably have syntax problems. Try to write rules with newline separator like this:

if $syslogfacility-text == 'local6' and $programname == 'httpd' then /var/log/httpd-access.log &
~

Or even better you can use modern RainerScript syntax instead of legacy format:

if ( $syslogfacility-text == 'local6' and $programname == 'httpd' )
then {
    action(type="omfile" file="/var/log/httpd-access.log")
    stop
}

It's more verbose and less ambiguous.
