Linux下rsyslog日志收集服务环境部署记录【转】

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。

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.

# ### begin forwarding rule ###

#*.* @@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/

.......

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

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：
[root@log-server ~]# yum install rsyslog -y
[root@log-server ~]# cp /etc/rsyslog.conf /etc/rsyslog.conf.bak
# rsyslog configuration file

# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html

==========================================================================
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
