Linux 之rsyslog+LogAnalyzer 日志收集系统

一、LogAnalyzer介绍
　　LogAnalyzer工具提供了一个易于使用，功能强大的前端，用于搜索，查看和分析网络活动数据，包括系统日志，事件日志和其他许多日志源。由于它只是将数据展示到我们用户的面前，所以数据本身需要由另一个程序收集，比如syslogd，rsyslog（现在是发行版的默认的syslogd），WinSyslog或MonitorWare代理。LogAnalyzer同样适用于Linux和Windows。它主要是用PHP编写的自由软件，基于GPL的开源应用程序。数据可以从数据库，也可以从纯文本文件而获得。

本案例规划图：

二、在rsyslog服务器上部署 LAMP环境。

1.安装httpd

[root@rsyslog ~]# yum install httpd -y
[root@rsyslog ~]# systemctl start httpd
[root@rsyslog ~]# systemctl enable httpd

2.安装mysql

[root@rsyslog ~]# yum install mysql mysql-server -y
[root@rsyslog ~]# systemctl start mariadb
[root@rsyslog ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@rsyslog ~]# mysqladmin -u root password 'rsyslog.ppp'

测试下登陆，无问题后，安装php

3.安装php

[root@rsyslog ~]# yum install php php-mysql php-gd -y
[root@rsyslog ~]# cat /var/www/html/test.php 
<?php
phpinfo();
?>

打开客户端浏览器，进行访问测试http://192.168.30.67/test.php

4.安装rsyslog,并加入开机启动

[root@rsyslog ~]# wget -O /etc/yum.repos.d/rsyslog.repo http://rpms.adiscon.com/v8-stable/rsyslog.repoc
[root@rsyslog ~]# yum install rsyslog-* --skip-broken -y
[root@rsyslog ~]# systemctl enable rsyslog

5.rsyslog建库脚本，路径在/usr/share/doc/rsyslog-mysql-8.18.0/createDB.sql，现在我们登陆数据库创建个rsyslogdb库，并导入建库脚本

[root@rsyslog ~]# more /usr/share/doc/rsyslog-mysql-8.18.0/createDB.sql 
CREATE DATABASE rsyslogdb;
USE rsyslogdb;

[root@rsyslog ~]# mysql -uroot -p < /usr/share/doc/rsyslog-mysql-8.18.0/createDB.sql 
Enter password:

登陆测试一下库建好了没

[root@rsyslog ~]# mysql -uroot -p rsyslogdb
Enter password: 
....
MariaDB [rsyslogdb]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| rsyslogdb          |
+--------------------+
4 rows in set (0.00 sec)

创建用户并授权
MariaDB [rsyslogdb]> GRANT ALL ON rsyslogdb.* TO rsyslogdbadmin@localhost IDENTIFIED BY 'rsyslog.ppp';
Query OK, 0 rows affected (0.00 sec)

MariaDB [rsyslogdb]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [rsyslogdb]> exit

最后测试下该用户的登陆
[root@rsyslog ~]# mysql -ursyslogdbadmin -p rsyslogdb

6.修改rsyslog.conf文件，修改后如下：

[root@rsyslog ~]# egrep -v '^$|^#' /etc/rsyslog.conf
$ModLoad ommysql
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal
$ModLoad immark  # provides --MARK-- message capability
$ModLoad imudp
$UDPServerRun 514
$ModLoad imtcp
$InputTCPServerRun 514
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$template Remote,"/data/log/%fromhost-ip%/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"
:fromhost-ip, !isequal, "127.0.0.1" ?Remote
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging on
$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none                /data/log/messages

cron.*                                                  /var/log/cron
*.emerg                                                 :omusrmsg:*
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log

重启rsyslog 服务，现在登陆mysql 进行验证。

MariaDB [rsyslogdb]> use rsyslogdb
Database changed
MariaDB [rsyslogdb]> select count(*) from SystemEvents;
+----------+
| count(*) |
+----------+
|       44 |
+----------+
1 row in set (0.00 sec)

MariaDB [rsyslogdb]> select * from SystemEvents where ID=1\G;

三、部署LogAnalyzer

1.下载

[root@rsyslog ~]# wget -c http://download.adiscon.com/loganalyzer/loganalyzer-3.6.6.tar.gz
解压
[root@rsyslog ~]# tar zxvf loganalyzer-3.6.6.tar.gz 
复制文件到
[root@rsyslog ~]# cp -r loganalyzer-3.6.6/src/ /var/www/html/loganalyzer
[root@rsyslog ~]# cp -r loganalyzer-3.6.6/contrib/* /var/www/html/loganalyzer/
进入到loganalyzer 程序中，将以下脚本赋予执行权限
[root@rsyslog ~]# cd /var/www/html/loganalyzer/
[root@rsyslog loganalyzer]# chmod +x configure.sh secure.sh 
运行configure.sh，将创建一个空白的config.php配置文件
[root@rsyslog loganalyzer]# ./configure.sh
