$ModLoad imklog # provides kernel logging support (previously done by rklogd)

#加载imklog模块，为内核登录提供支持

#$ModLoad immark # provides --MARK-- message capability

# Provides TCP syslog reception

#$ModLoad imtcp

#$InputTCPServerRun

#加栽TCP摸块,允许使用TCP的514编口接收采用TCP协议转发的日志

#### GLOBAL DIRECTIVES ####

#定义全局设置

#Use default timestamp format

#ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat #定义曰志的时间使用默认的时间戳格式

#File syncing capability is disabled by default. This feature is usually not required,

#not useful and an extreme performance hit

#$ActionFileEnableSync on

#文件同步功能。默认没有开启,是注释的

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

$IncludeConfig /etc/rsyslog.d/*.conf

#包含/etx/tsyslog.d/目录中所有的".conf"子配置文件。也就是说，这个目录中的所有子配置文件也同时生效

#### RULES ####

#日志文件保存规则

#Log all kernel messages to the console.

#Logging much else clutters up the screen.

#kern.* /dev/console

#kern服务.所有曰志级别 保存在/dev/console

#这个日志默认没有开启,如果需要，则取消注释

#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

#所有服务.info以上级到的日志保存在/var/log/messages日志文件中

#mail, authpriv^ cron的B志不记录在/var/log/messages曰志文件中，因为它们部有自己的曰志文件

#所以/var/log/messages日志是最重要的系统日志文件，需要经常查看

#The authpriv file has restricted access.

authpriv.* /var/log/secure

#用户认证服务所有级别的日志保存在/vai/1og/secure日志文件中

#Log all the mail messages in one place.

mail.* -/var/log/maillog

#mail服务的所有级别的日志保存在/var/log/maillog 日志文件中

#"-"的含义是日志先在内存中保存.当曰志足够多之后.再向文件中保存

# Log cron stuff

cron.* /var/log/cron

#计対任务的所有日志保存在/var/log/cron日志文件中

# Everybody gets emergency messages

#所有日志服务的疼痛等级日志对所有在线用户广播

#Save news errors of level crit and higher in a special file. uucp,news.crit /var/log/spooler

#uucp和news曰志服务的crit以上级别的日志保存在/var/log/sppoler曰志文件中

#Save boot messages also to boot.log

local7.* /var/log/boot.log

#loacl7 日志服务的所有日志写入/var/log/boot.log 日志文件中 #会把开机时的检测信息在显示到屏幕的同时写入/var/log/boot.log 日志文件中

# ### begin forwarding rule ###

#定义转发规到

#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. #SWorkDirectory /var/lib/rsyslog # where to place spool files #$ActionQueueFileName fwdRulel # 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 t 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 #*•* @6remote-host:514

# ### end of the forwarding rule ##
