해당 파일에 아래 내용 수정 및 추가하기

# syslog 수신 포트 설정
module(load="imudp") # 주석 제거하여 활성화
input(type="imudp" port="514") # 주석 제거하여 활성화

# syslog 수신 시 저장할 위치 및 파일 설정 템플릿
$template Remote,"/var/log/rsyslog/%fromhost-ip%/%$YEAR%-%$MONTH%-%$DAY%.log" 

# syslog 수신 시 fromhost-ip가 127.0.0.1이 아닌 경우 템플릿 Remote 정책을 적용
:fromhost-ip, !isequal, "127.0.0.1" ?Remote

# 템플릿 Remote로 수신한 경우 로그 처리 중지
# 중지하지 않을 경우, OS에서 수집하는 syslog나 message에도 로그가 수집 됨 (중복 수집 됨)

#### MODULES ####

module(load="imuxsock"    # provides support for local system logging (e.g. via logger command)
       SysSock.Use="off") # Turn off message reception via local log socket;
                          # local messages are retrieved through imjournal now.
module(load="imjournal"             # provides access to the systemd journal
       StateFile="imjournal.state") # File to store the position in the journal
#module(load="imklog") # reads kernel messages (the same are read from journald)
#module(load="immark") # provides --MARK-- message capability

# Provides UDP syslog reception
# for parameters see http://www.rsyslog.com/doc/imudp.html
module(load="imudp") # needs to be done just once 주석제거하여 활성화
input(type="imudp" port="514") # 주석제거하여 활성화

# Provides TCP syslog reception

#### Template ###
$template Remote,"/var/log/rsyslog/%fromhost-ip%/%$YEAR%-%$MONTH%-%$DAY%.log"

#### RULES ####

# 로그가 Remote template을 거친 경우 여기서 로그 수집 중단
# 로그 수집이 중단되지 않을 경우 해당 경로 이후의 syslog 프로세스를 거침
# 일반적으로 syslog나 message 파일에 등록 되어 Remote template에도 등록이 되었기 때문에 중복 메시지가 됨.
