Linux Configuration for rsyslog central log host

(24 July 2013)

CentOS 6 uses rsyslog 5.8.

# rsyslog v5 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 ####

$ModLoad imuxsock # provides support for local system logging (e.g. via logger command) $ModLoad imklog # provides kernel logging support (previously done by rklogd) #$ModLoad immark # provides --MARK-- message capability

# Provides UDP syslog reception $ModLoad imudp $UDPServerRun 514

# Provides TCP syslog reception $ModLoad imtcp $InputTCPServerRun 514

#### GLOBAL DIRECTIVES ####

# 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

#### 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 #*.debug;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 *

# 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) # The statement between the begin … end define a SINGLE forwarding # rule.

Comments

  • This is mostly stock (I believe) -- the magic for the /var/log/HOSTS stuff is at teh bottom, the DynFile and the template
  • You might have to restorecon -Rv /etc/rsyslog.conf after putting a new version of the file in place. I did. The error was the monumentally unhelpful
# service rsyslog start

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
