Centos 7에서 rsyslog 서비스를 시작하려고 시도했지만 작동하지 않습니다. 구성 파일 참조 -
# rsyslog configuration file
# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
#### MODULES ####
# The imjournal module bellow is now used as a message source instead of imuxsock.
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal
#$ModLoad imklog # reads kernel messages (the same are read from journald)
#$ModLoad immark # provides --MARK-- message capability
# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514
# Provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 10544
#### GLOBAL DIRECTIVES ####
# Where to place auxiliary files
$WorkDirectory /var/lib/rsyslog
# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
# File syncing capability is disabled by default. This feature is usually not required,
# not useful and an extreme performance hit
#$ActionFileEnableSync on
# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf
# Turn off message reception via local log socket;
# local messages are retrieved through imjournal now.
$OmitLocalLogging on
# File to store the position in the journal
$IMJournalStateFile imjournal.state
#### RULES ####
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.* /dev/console
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none /var/log/messages
# The authpriv file has restricted access.
authpriv.* /var/log/secure
# Log all the mail messages in one place.
mail.* -/var/log/maillog
# Log cron stuff
cron.* /var/log/cron
# Everybody gets emergency messages
*.emerg :omusrmsg:*
# Save news errors of level crit and higher in a special file.
uucp,news.crit /var/log/spooler
# Save boot messages also to boot.log
local7.* /var/log/boot.log
# ### begin forwarding rule ###
# The statement between the begin ... end define a SINGLE forwarding
# rule. They belong together, do NOT split them. If you create multiple
# forwarding rules, duplicate the whole block!
# Remote Logging (we use TCP for reliable delivery)
#
# An on-disk queue is created for this action. If the remote host is
# down, messages are spooled to disk and sent when it is up again.
#$ActionQueueFileName fwdRule1 # unique name prefix for spool files
#$ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible)
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
#$ActionQueueType LinkedList # run asynchronously
#$ActionResumeRetryCount -1 # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
#*.* @@remote-host:514
# ### end of the forwarding rule ###
아래에는 netstat 출력도 있습니다. 어디에서나 rsyslog 서비스가 실행되는 것을 볼 수 없습니다.

다음을 사용하여 rsyslogconf를 확인해 보십시오. rsyslogd -f /etc/rsyslog.conf -N 1
모든 것이 정상이면 systemd-journald.socket
다음을 사용하여 다시 시작해 보십시오.
systemctl restart systemd-journald.socket
다음 명령을 사용하여 시작되었는지 logger
확인할 수 있습니다.rsyslog
logger "hello"
답변2
SELinux가 활성화되어 있을 수 있으며 이로 인해 rsyslogd가 tcp 수신기에 대해 선택한 비표준 syslog 포트 10544에 바인딩되지 않습니다. SELinux를 완전히 비활성화하거나 다음 명령을 실행하고 rsyslog를 다시 시작하십시오.
semanage port -a -t syslogd_port_t -p tcp 10544
/etc/rsyslog.d에 포함된 구성 파일에도 오류가 있을 수 있습니다. rsyslogd가 실행되지 않을 때 다음 명령을 실행하여 구성 파일을 확인하세요.
rsyslogd -f /etc/rsyslog.conf -N 1
