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. mail.* -/var/log/maillog local4.* /data/fw.log # 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.

====================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/ [root@zabbix fw_logs]# ll total 12K drwxrwxrwx 6 root root 84 Aug 16 18:28 . drwxr-xr-x. 18 root root 4.0K Aug 16 17:58 .. drwx------ 2 root root 74 Aug 17 09:50 172.19.10.24 drwx------ 2 root root 74 Aug 17 10:00 172.19.10.25 drwx------ 2 root root 4.0K Aug 17 00:01 192.168.17.41 drwx------ 2 root root 4.0K Aug 17 00:01 192.168.17.42 [root@zabbix fw_logs]# cd 172.19.10.24/ [root@zabbix 172.19.10.24]# ll total 20K drwx------ 2 root root 74 Aug 17 09:50 . drwxrwxrwx 6 root root 84 Aug 16 18:28 .. -rw------- 1 root root 14K Aug 16 20:45 172.19.10.24_2017-08-16.log -rw------- 1 root root 771 Aug 17 10:03 172.19.10.24_2017-08-17.log [root@zabbix 172.19.10.24]# cat 172.19.10.24_2017-08-16.log Aug 16 18:39:56 gitlab bash[138413]: user=root,ppid=124297,from=172.19.16.28 29338 22,pwd=/root,command:[2017-08-16 18:39:56]root pts/5 2017-08-16 17:23 (172.19.16.28)/etc/init.d/rsyslog restart Aug 16 18:39:56 gitlab bash[138418]: user=root,ppid=124297,from=172.19.16.28 29338 22,pwd=/root,command:[2017-08-16 18:39:56]root pts/5 2017-08-16 17:23 (172.19.16.28)/etc/init.d/rsyslog restart Aug 16 18:39:56 gitlab bash[138422]: user=root,ppid=124297,from=172.19.16.28 29338 22,pwd=/root,command:[2017-08-16 18:39:56]root pts/5 2017-08-16 17:23 (172.19.16.28)/etc/init.d/rsyslog restart Aug 16 18:39:57 gitlab bash[138426]: user=root,ppid=124297,from=172.19.16.28 29338 22,pwd=/root,command:[2017-08-16 18:39:56]root pts/5 2017-08-16 17:23 (172.19.16.28)/etc/init.d/rsyslog restart Aug 16 18:40:30 gitlab bash[138610]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/root,command:[2017-08-16 18:40:03]root pts/0 2017-08-16 18:40 (172.16.255.202)exit Aug 16 18:40:43 gitlab bash[138652]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data,command:[2017-08-16 18:40:43]root pts/0 2017-08-16 18:40 (172.16.255.202)cd /data/ Aug 16 18:40:43 gitlab bash[138657]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data,command:[2017-08-16 18:40:43]root pts/0 2017-08-16 18:40 (172.16.255.202)ls Aug 16 18:40:47 gitlab bash[138666]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data,command:[2017-08-16 18:40:47]root pts/0 2017-08-16 18:40 (172.16.255.202)mkdir hahahahah Aug 16 18:40:48 gitlab bash[138671]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data/hahahahah,command:[2017-08-16 18:40:48]root pts/0 2017-08-16 18:40 (172.16.255.202)cd hahahahah/ Aug 16 18:40:48 gitlab bash[138677]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data/hahahahah,command:[2017-08-16 18:40:48]root pts/0 2017-08-16 18:40 (172.16.255.202)ls Aug 16 18:40:54 gitlab bash[138696]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data/hahahahah,command:[2017-08-16 18:40:54]root pts/0 2017-08-16 18:40 (172.16.255.202)echo "Asdfasdf" >heihei Aug 16 18:40:54 gitlab bash[138702]: user=root,ppid=138586,from=172.16.255.202 52496 22,pwd=/data/hahahahah,command:[2017-08-16 18:40:54]root pts/0 2017-08-16 18:40 (172.16.255.202)ls ....... 有上面日志可以看出，在172.19.10.24这台机器上的操作记录都被详细记录下来了。这样，就能清楚地知道登录到这台机器上的用户都做了些什么了.......
=====================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 [root@nginx-server ~]# cp /etc/rsyslog.conf /etc/rsyslog.conf.bak [root@nginx-server ~]# cat /etc/rsyslog.conf # rsyslog v5 configuration file

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]

2）192.168.10.52为rsyslog服务端，即日志的接收端。 配置如下： [root@log-server ~]# yum install rsyslog -y [root@log-server ~]# cp /etc/rsyslog.conf /etc/rsyslog.conf.bak # rsyslog configuration file
