Centos7 配置rsyslog客户端接收远程日志 因为路由器我设定每天重启，但是日志一重启就会清除，并且路由器最多只能保存1024条记录，所以我想把路由器的日志记录到一台服务器上，发现路由器包含远程日志功能于是我就在我的centos7服务器配置了下rsyslog，把日志记录到这里编辑服务端的/etc/rsyslog.conf文件注意下中文注释地方# 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 # 引用udp协议的模块 $UDPServerRun 514 # 设置udp协议使用端口 # Provides TCP syslog reception $ModLoad imtcp # 引用tcp协议的模块 $InputTCPServerRun 514 # 设置tcp协议使用端口 #### GLOBAL DIRECTIVES #### # Where to place auxiliary files $WorkDirectory /var/lib/rsyslog # Use default timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $template Remote,"/var/log/%$YEAR%-%$MONTH%-%$DAY%/%fromhost-ip%.log" # 设置远程日志存放路径和文件格式 :fromhost-ip, !isequal, "127.0.0.1" ?Remote # 如果是本机日志则不记录 # 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 $IMJournalStateFile imjournal.state #### RULES #### # Log all kernel messages to the console. # Logging much else clutters up the screen. # 关于内核的所有日志都放到/dev/console(控制台) #kern.* /dev/console # Log anything (except mail) of level info or higher. # Don't log private authentication messages! # 记录所有日志类型的info级别以及大于info级别的信息到/var/log/messages，但是mail邮件信息，authpriv验证方面的信息和cron时间任务相关的信息除外 *.info;mail.none;authpriv.none;cron.none /var/log/messages # The authpriv file has restricted access. # authpriv验证相关的所有信息存放在/var/log/secure authpriv.* /var/log/secure # Log all the mail messages in one place. # 邮件的所有信息存放在/var/log/maillog; 这里有一个-符号, 表示是使用异步的方式记录, 因为日志一般会比较大 mail.* -/var/log/maillog # Log cron stuff # 计划任务有关的信息存放在/var/log/cron cron.* /var/log/cron # Everybody gets emergency messages # 启动的相关信息 *.emerg :omusrmsg:* # Save news errors of level crit and higher in a special file. uucp,news.crit /var/log/spooler # Save boot messages also to boot.log local7.* /var/log/boot.log # ### begin forwarding rule ### # The statement between the begin ... end define a SINGLE forwarding # rule. They belong together, do NOT split them. If you create multiple # forwarding rules, duplicate the whole block! # Remote Logging (we use TCP for reliable delivery) # # An on-disk queue is created for this action. If the remote host is # down, messages are spooled to disk and sent when it is up again. #$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 ###然后重启rsyslogsystemctl restart rsyslog客户端直接填写ip，端口默认是514，就完成了
