rsyslogd 실행 및 재시작

 

 

 

systemctl에 의해  /sbin/rsyslogd의 데몬프로세스가 수행된다.

 

 

 

 

 

rsyslog.conf 읽음

 

/sbin/rsyslogd 데몬이 실행되면서 /etc/rsyslog.conf파일을 읽어들이게 된다.

 

 

 

  /etc/syslog.conf파일에는 시스템에서 사용하는 대부분의 로그파일들에 관해 설정되어있다.

 

 

 

 

 

rsyslogd.pid 기록

 

/sbin/syslogd도 데몬(일종의 프로세스)이므로 이 프로세스의 실행번호(Process ID : PID)/run/rsyslogd.pid에 기록하게 된다.

 

 

 

 

 

rsyslog.conf에 설정된 각각의 로그파일들에 대한 로그저장 시작

 

/sbin/rsyslogd의 실행과 함께 rsyslog.conf파일에 설정되어있는 각각의 로그파일들(messages, secure, maillog)이 기록되기 시작한다.

 

 

 

 rsyslog.conf파일의 내용을 잠시 살펴보면 다음과 같다.

 

 

 

 

 

[root@RockyLinux ~]# cat /etc/rsyslog.conf

# rsyslog configuration file

 

# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html

# or latest version online at http://www.rsyslog.com/doc/rsyslog_conf.html

# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html

 

#### GLOBAL DIRECTIVES ####

 

# Where to place auxiliary files

global(workDirectory="/var/lib/rsyslog")

 

# Use default timestamp format

module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat")

 

# Include all config files in /etc/rsyslog.d/

include(file="/etc/rsyslog.d/*.conf" mode="optional")

 

#### 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

#input(type="imudp" port="514")

 

# Provides TCP syslog reception

# for parameters see http://www.rsyslog.com/doc/imtcp.html

#module(load="imtcp") # needs to be done just once

#input(type="imtcp" port="514")

 

#### RULES ####

 

# Log all kernel messages to the console.

# Logging much else clutters up the screen.

#kern.*                                                 /dev/console

 

# Log anything (except mail) of level info or higher.

# Don't log private authentication messages!

*.info;mail.none;authpriv.none;cron.none                /var/log/messages

 

# The authpriv file has restricted access.

authpriv.*                                              /var/log/secure

 

# Log all the mail messages in one place.

mail.*                                                  -/var/log/maillog

 

 

# Log cron stuff

cron.*                                                  /var/log/cron

 

# Everybody gets emergency messages

*.emerg                                                 :omusrmsg:*

 

# Save news errors of level crit and higher in a special file.

uucp,news.crit                                          /var/log/spooler

 

# Save boot messages also to boot.log

local7.*                                                /var/log/boot.log

 

 

# ### sample forwarding rule ###

#action(type="omfwd"

# # An on-disk queue is created for this action. If the remote host is

# # down, messages are spooled to disk and sent when it is up again.

#queue.filename="fwdRule1"       # unique name prefix for spool files

#queue.maxdiskspace="1g"         # 1gb space limit (use as much as possible)

#queue.saveonshutdown="on"       # save messages to disk on shutdown

#queue.type="LinkedList"         # run asynchronously

#action.resumeRetryCount="-1"    # infinite retries if host is down

# # Remote Logging (we use TCP for reliable delivery)

# # remote_host is: name/ip, e.g. 192.168.0.1, port optional e.g. 10514

#Target="remote_host" Port="XXX" Protocol="tcp")

[root@RockyLinux ~]#
