实验目的：以报表图形格式展示数据库，便于观看和理解

实验工具：三台主机（A主机：centos7--配置数据库 B主机：centos6--记录日志 C主机：centos6-1--实现以报表方式展示数据库中的日志）

实验步骤如下：

一、A机器centos7(192.168.152.167)：安装并配置对应数据库

①安装数据库包

[root@centos7 ~]# yum install mariadb-server
[root@centos7 ~]# systemctl start mariadb
[root@centos7 ~]# mysql_secure_installation 
[root@centos7 ~]# mysql -uroot -p123456 < createDB.sql

②创建数据库用户

[root@centos7 ~]# mysql -uroot -p123456 
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 10
Server version: 5.5.52-MariaDB MariaDB Server

MariaDB [(none)]> show databases;

MariaDB [(none)]> use Syslog;

MariaDB [Syslog]> show tables;

2 rows in set (0.00 sec)
2 rows in set (0.00 sec)

MariaDB [Syslog]> grant all on Syslog.* to loguser@‘192.168.152.166‘ identified by ‘123456‘;
Query OK, 0 rows affected (0.00 sec)

二、centos6(192.168.152.166)准备日志

①安装软件包并修改配置文件

[root@centos6 ~]# yum install rsyslog-mysql
[root@centos6 ~]# scp /usr/share/doc/rsyslog-mysql-5.8.10/createDB.sql 192.168.152.167:
[root@centos6 ~]# vim /etc/rsyslog.conf (配置日志文件）
#*.info;mail.none;authpriv.none;cron.none /var/log/messages
*.info;mail.none;authpriv.none;cron.none :ommysql:192.168.152.167,Syslog,loguser,123456

②重启rsyslog服务

[root@centos6 ~]# service rsyslog restart 
Shutting down system logger: [ OK ]
Starting system logger: [ OK ]
测试一下数据是否写入：
[root@centos6 ~]# logger "this is a test log"

三、centos6-1(192.168.152.168)配置

①在rsyslog服务器上准备amp

[root@centos6 ~]# cd /var/www/html/
[root@centos6 /var/www/html]# yum install httpd php php-mysql php-gd

②安装并配置loganalyzer

[root@centos6 /var/www/html]# tar xvf loganalyzer-4.1.5.tar.gz
[root@centos6 /var/www/html/loganalyzer-4.1.5]# cp -r src/ /var/www/html/log
[root@centos6 /var/www/html/loganalyzer-4.1.5]# cd /var/www/html/log
[root@centos6 /var/www/html/log]# touch config.php
[root@centos6 /var/www/html/log]# chmod 666 config.php 
[root@centos6 /var/www/html/log]# service httpd restart
