Linux下rsyslog日志收集服务环境部署记录
rsyslog 可以理解为多线程增强版的syslog。 在syslog的基础上扩展了很多其他功能,如数据库支持(MySQL、PostgreSQL、Oracle等)、日志内容筛选、定义日志格式模板等。目前大多数Linux发行版默认也是使用rsyslog进行日志记录。rsyslog提供了三种远程传输协议:
- UDP 传输协议
- 基于传统UDP协议进行远程日志传输,也是传统syslog使用的传输协议; 可靠性比较低,但性能损耗最少, 在网络情况比较差, 或者接收服务器压力比较高情况下,
- 可能存在丢日志情况。 在对日志完整性要求不是很高,在可靠的局域网环境下可以使用。
- TCP 传输协议
- 基于传统TCP协议明文传输,需要回传进行确认,可靠性比较高; 但在接收服务器宕机或者两者之间网络出问题的情况下,会出现丢日志情况。 这种协议相比于UDP在
- 可靠性方面已经好很多,并且rsyslog原生支持,配置简单, 同时针对可能丢日志情况,可以进行额外配置提高可靠性,因此使用比较广。
- RELP 传输协议
- RELP(Reliable Event Logging Protocol)是基于TCP封装的可靠日志消息传输协议; 是为了解决TCP 与 UDP 协议的缺点而在应用层实现的传输协议,也是三者
- 之中最可靠的。 需要多安装一个包rsyslog-relp以支持该协议。
- 对于线上服务器,为了日志安全起见,建议使用还是使用 RELP 协议进行传输。
rsyslog的简单配置记录(如下将公司防火墙上的日志(UDP)打到IDC的rsyslog日志服务器上)
- 一、rsyslog服务端的部署
- 安装rsyslog 程序(rsyslog默认已经在各发行版安装,如果系统中没有的话,可以用yum 进行安装,如下:)
- [root@zabbix ~]# yum install rsyslog -y
- 配置:
- [root@zabbix ~]# cat /etc/rsyslog.conf
- # 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 #开启udp的514端口。也可以开启tcp的514端口,这里只接受udp的
- $UDPServerRun 514
- # Provides TCP syslog reception
- #$ModLoad imtcp
- #$InputTCPServerRun 514
- $WorkDirectory /var/lib/rsyslog
- $AllowedSender udp, 192.168.17.0/8 #仅仅接收来自192.168.17.0/8网段的主机的udp日志(这个是公司防火墙的ip地址)
- #### GLOBAL DIRECTIVES ####
- # Use default timestamp format
- $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
- $template Remote,"/data/fw_logs/%fromhost-ip%/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log" #定义模板,接受日志文件路径,区分了不同主机的日志
- :fromhost-ip, !isequal, "127.0.0.1" ?Remote # 过滤server 本机的日志
- # 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
- # The authpriv file has restricted access.
- authpriv.* /var/log/secure
- # Log all the mail messages in one place.

- # 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.
- #$WorkDirectory /var/lib/rsyslog # where to place spool files
- #$ActionQueueFileName fwdRule1 # unique name prefix for spool files

- #$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 ###
- [root@zabbix ~]# mkdir /data/fw_logs/
- [root@zabbix ~]# /etc/init.d/rsyslog restart
- 二、在公司防火墙(192.168.17.41/42)上配置udp日志输出策略(在防火墙添加rsyslog服务端的ip和514端口)
- 三、过一会儿,在rsyslog日志服务器上设置的日志目录下就能看到防火墙的日志输出了
- [root@zabbix ~]# ll /data/fw_logs/
- total 4.0K
- drwxrwxrwx 4 root root 46 Jul 28 10:40 .
- drwxr-xr-x. 18 root root 4.0K Jul 28 10:38 ..
- drwx------ 2 root root 41 Jul 28 10:37 192.168.17.41
- drwx------ 2 root root 41 Jul 28 10:40 192.168.17.42
- [root@zabbix ~]# ll /data/fw_logs/192.168.17.41
- total 16K
- drwx------ 2 root root 41 Jul 28 10:37 .
- drwxrwxrwx 4 root root 46 Jul 28 10:40 ..
- -rw------- 1 root root 13K Jul 28 14:02 192.168.17.41_2017-07-28.log
- ------------------------------------------------------------------------------------
- 可以将上面rsyslog服务端的rsyslog.conf里的ip白名单设置为客户机的ip端,比如:
- $AllowedSender tcp, 172.18.0.0/16 #表示接收172.18.0.0/16网段的客户机的tcp日志输入,前提是打开tcp的514端口
- 客户机的配置:
- 只需要在rsyslog.conf文件里添加下面一行:
- *.* @172.18.10.20 #后面的ip是rsyslog服务端的ip地址
- 启动rsyslog日志即可!
====================再看一例=======================
以上配置的是将公司防火墙的日志打到rsyslog里。现在有这么一个需求:
公司IDC的另外两台服务器172.19.10.24和172.19.10.25上部署了gitlab、nexus、jenkins、jira和wiki,上面的权限设置的比较杂,很多人都有登录需求。现在需要将登录到这两台服务器上的用户的所有操作过程记录下来,记录达到rsyslog日志里,相当于做用户操作记录的审计工作。
- 配置如下(结合上面的安装配置)(服务端的ip是172.19.16.21):
- 1)rsyslog服务端配置 (相比于上面的配置,这里去掉了AllowedSender的来源ip的白名单限制。即允许接收所有机器的日志;上面的防火墙日志还是能继续收集)
- [root@zabbix ~]# cat /etc/rsyslog.conf|grep -v "#"|grep -v "^$"
- $ModLoad imudp
- $UDPServerRun 514
- $WorkDirectory /var/lib/rsyslog
- $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
- $template Remote,"/data/fw_logs/%fromhost-ip%/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"
- :fromhost-ip, !isequal, "127.0.0.1" ?Remote
- $IncludeConfig /etc/rsyslog.d/*.conf
- *.info;mail.none;authpriv.none;cron.none /var/log/messages
- authpriv.* /var/log/secure
- mail.* -/var/log/maillog
- cron.* /var/log/cron
- *.emerg *
- uucp,news.crit /var/log/spooler
- local7.* /var/log/boot.log
- local5.* /var/log/history.log
- [root@zabbix ~]# /etc/init.d/rsyslog restart
- 2)在172.19.10.24上的配置
- [root@gitlab ~]# cat /etc/rsyslog.conf|grep -v "#"|grep -v "^$"
- $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
- $IncludeConfig /etc/rsyslog.d/*.conf
- *.info;mail.none;authpriv.none;cron.none /var/log/messages
- authpriv.* /var/log/secure
- mail.* -/var/log/maillog
- cron.* /var/log/cron
- *.emerg *
- uucp,news.crit /var/log/spooler
- local7.* /var/log/boot.log
- local5.* @172.19.16.21
- [root@gitlab ~]# /etc/init.d/rsyslog restart
- [root@gitlab ~]# cat /etc/profile #在该文件的底部添加下面内容
- .......
- export HISTTIMEFORMAT
- export PROMPT_COMMAND='{ command=$(history 1 | { read x y; echo $y; }); logger -p local5.notice -t bash -i "user=$USER,ppid=$PPID,from=$SSH_CLIENT,pwd=$PWD,command:$command"; }'
- 3)在另一台172.19.10.25上做类似配置配置
- [root@nexus ~]# cat /etc/rsyslog.conf |grep -v "#"|grep -v "^$"
- $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
- $IncludeConfig /etc/rsyslog.d/*.conf
- *.info;mail.none;authpriv.none;cron.none /var/log/messages
- authpriv.* /var/log/secure
- mail.* -/var/log/maillog
- cron.* /var/log/cron
- *.emerg *
- uucp,news.crit /var/log/spooler
- local7.* /var/log/boot.log
- local5.* @172.19.16.21
- [root@nexus ~]# /etc/init.d/rsyslog restart
- [root@nexus ~]# cat /etc/profile
- .......
- export HISTTIMEFORMAT
- export PROMPT_COMMAND='{ command=$(history 1 | { read x y; echo $y; }); logger -p local5.notice -t bash -i "user=$USER,ppid=$PPID,from=$SSH_CLIENT,pwd=$PWD,command:$command"; }'
- 4)过一段时间,发现在rsyslog服务端的日志目录/data/fw_logs下面已经有收集到的日志了
- [root@zabbix fw_logs]# pwd
- /data/fw_logs
- [root@zabbix fw_logs]# cd
- [root@zabbix ~]# cd /data/fw_logs/

=====================通过rsyslog收集nginx日志到远程服务器上====================
需求说明:通过rsyslog服务将192.168.10.21服务器上的/data/nginx/logs/www.kevin.com-access.log日志实时同步到192.168.10.52服务器上(路径为/data/rsyslog/nginx)。
1)192.168.10.21为rsyslog客户端,即日志的推送端。rsyslog日志是客户机主动将自己的日志推送到远程服务器上。
操作如下:
[root@nginx-server ~]# yum install rsyslog -y

重启rsyslog服务
[root@nginx-server ~]# /etc/init.d/rsyslog restart
关闭系统日志记录器: [确定]
启动系统日志记录器: [确定]
由于作为日志的推送端,rsyslog日志不需要开启514端口(如上在rsyslog.conf文件里没有打开dup或tcp的514端口)
[root@nginx-server ~]# lsof -i:514
[root@nginx-server ~]#
2)192.168.10.52为rsyslog服务端,即日志的接收端。
配置如下:

=========================温馨提示========================
rsyslog也可以收集多个日志文件,需要注意的是:
$InputFileTag 定义的APPNAME必须唯一,同一台主机上不同的应用应当使用不同的APPNAME,否则会导致新定义的TOKEN和TAG不生效;
$template 定义的模板名必须唯一,否则会导致新定义的TOKEN和TAG不生效;
$InputFileStateFile 定义的StateFile必须唯一,它被rsyslog用于记录文件上传进度,否则会导致混乱;
如下是rsyslog收集多个日志的配置,这里以2个日志文件为例:
日志的推送端配置
- [root@external-lb01 ~]# cat /etc/rsyslog.conf
- ..........
- $ModLoad imfile
- .........
- *.info;mail.none;authpriv.none;cron.none;local5.none;local4.none /var/log/messages
- .........
- $InputFileName /data/nginx/logs/portal.kevin.com-access.log
- $InputFileTag portal_access
- $InputFileSeverity info
- $InputFileStateFile /etc/rsyslog.d/stat1-access
- $InputFileFacility local4
- $InputFilePollInterval 1
- $InputFilePersistStateInterval 1
- $InputRunFileMonitor
- local4.* @192.168.10.52
- $InputFileName /data/nginx/logs/www.kevin.com-access.log
- $InputFileTag web_access
- $InputFileSeverity info
- $InputFileStateFile /etc/rsyslog.d/stat-access
- $InputFileFacility local5
- $InputFilePollInterval 1
- $InputFilePersistStateInterval 1
- $InputRunFileMonitor
- local5.* @192.168.10.52
- 重启日志发送端的rsyslog服务
- [root@external-lb01 ~]# /etc/init.d/rsyslog restart
日志的接收端配置
- [root@open-falcon01 ~]# cat /etc/rsyslog.conf
- ........
- $ModLoad imudp
- $UDPServerRun 514
- # Provides TCP syslog reception
- $ModLoad imtcp
- $InputTCPServerRun 514
- .........
- $template SpiceTmpl,"%msg%\n"
- $template DynaFile,"/data/external-lb/nginx/nginx-access.log"
- $template SpiceTmpl2,"%msg%\n"
- $template DynaFile2,"/data/external-lb/portal/portal-access.log"
- .........
- *.info;mail.none;authpriv.none;cron.none;local5.none;local4.none /var/log/messages
- .........
- local5.* ?DynaFile;SpiceTmpl
- local4.* ?DynaFile2;SpiceTmpl2
- 重启日志接收端的rsyslog服务
- [root@open-falcon01 ~]# /etc/init.d/rsyslog restart
- 查看,当访问对应对应的url时,就会有转发后的文件产生,并实时有日志内容转发过来
- [root@open-falcon01 ~]# ll /data/external-lb/nginx/nginx-access.log
- -rw------- 1 root root 1067372 Oct 9 10:51 /data/external-lb/nginx/nginx-access.log
- [root@open-falcon01 ~]# ll /data/external-lb/portal/portal-access.log
- -rw------- 1 root root 88141 Oct 9 22:26 /data/external-lb/portal/portal-access.log
==========================================================================
注意:
a)如果发现日志还没有接收过来,即/data/rsyslog/nginx目录下没有日志产生,就同时重启推送端和接收端的rsyslog服务。确保双方的iptables防火墙和selinux关闭!
b)也可以自行修改接收的日志文件的存放路径,如改为下面的配置:
$template DynaFile,"/data/rsyslog/nginx/nginx-access.log"
则日志收集后存放的文件如下:
[root@log-server ~]# ll /data/rsyslog/nginx/
total 571716
-rw------- 1 root root 483539594 Jun 13 12:58 2018-06-13.log
-rw------- 1 root root 101893593 Jun 13 13:13 nginx-access.log
