通过 loganalyzer 展示数据库中的日志
环境准备
三台主机
一台日志服务器,利用上一个案例实现,IP:192.168.39.7,
一台数据库服务器,利用上一个案例实现,IP:192.168.39.27,
一台当httpd+php 服务器,并安装loganalyzer展示web图形,IP:192.168.39.77
日志服务器工具 loganalyzer-4.1.8.tar.gz
准备服务器:
# 日志服务器
[root@centos7 ~]$hostname rsyslog
[root@centos7 ~]$exit
[root@rsyslog ~]$
# 数据库服务器
[root@centos7 ~]$hostname mysql
[root@centos7 ~]$exit
[root@mysql ~]$
# websrv服务器
[root@centos ~]# hostname websrv
[root@centos ~]# exit
[root@websrv ~]$
日志服务器:
- 在rsyslog服务器上安装连接mysql模块相关的程序包
[root@rsyslog ~]$yum install rsyslog-mysql -y
- 找到sql脚本发送到数据库
# 下载辅助软件查找
[root@rsyslog ~]$yum install mlocate
[root@rsyslog ~]$updatedb # 更新数据库信息
[root@rsyslog ~]$locate mysql-createDB.sql # 使用locatedb查找脚本文件存放路径
/usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql
[root@rsyslog ~]$cat /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql # 脚本文件内容
CREATE DATABASE Syslog;
USE Syslog;

- 修改配置文件启动服务模块并且写如数据库信息(用于给数据库服务器发送日志信息)
# The imjournal module bellow is now used as a message source instead of imuxsock.
$ModLoad ommysql # 添加这一行
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none /var/log/messages
*.info;mail.none;authpriv.none;cron.none :ommysql:192.168.39.27,Syslog,syslog,taotaobao
#配置rsyslog将日志保存到mysql中
[root@centos8 ~]#vim /etc/rsyslog.conf
####MODULES####
#在 MODULES 语言下面,如果是 CentOS 8 加下面行
module(load="ommysql")
#在 MODULES 语言下面,如果是 CentOS 7,6 加下面行
$ModLoad ommysql
数据库服务器:
- 安装数据库
[root@mysql ~]$yum install mariadb-server -y
[root@mysql ~]$systemctl start mariadb.service
- 执行考过来的脚本
[root@mysql ~]$mysql <
anaconda-ks.cfg .cshrc .tcshrc
.bash_history ifcfg-eth0 .viminfo
.bash_logout init_env_191113.sh .vimrc
.bash_profile mysql-createDB.sql
.bashrc .pki/
[root@mysql ~]$mysql < mysql-createDB.sql # 直接导入数据库
- 创建Syslog库使用的账号
[root@mysql ~]$mysql

Query OK, 0 rows affected (0.00 sec)
测试日志服务器和数据库是否连接:
- 数据库端查看Syslog库没启动服务之前是空的
MariaDB [Syslog]> show tables;
+------------------------+
| Tables_in_Syslog |
+------------------------+
| SystemEvents |
| SystemEventsProperties |
+------------------------+
2 rows in set (0.00 sec)
MariaDB [Syslog]>
MariaDB [Syslog]> SELECT COUNT(*) FROM SystemEvents;
+----------+
| COUNT(*) |
+----------+
| 0 |
+----------+
1 row in set (0.00 sec)
- 启动rsyslog服务
[root@rsyslog ~]$systemctl restart rsyslog.service
[root@rsyslog ~]$logger "this is a test log" # 日志服务器触发日志(logger触发日志命令)
- 查看数据库是否有数据(可以多测试几遍)
MariaDB [Syslog]> SELECT COUNT(*) FROM SystemEvents;
+----------+
| COUNT(*) |
+----------+
| 8 |
+----------+
1 row in set (0.00 sec)
websrv服务器端:
- 解压缩工具
[root@websrv ~]# ll
-rw-r--r-- 1 root root 2943754 Oct 10 13:04 loganalyzer-4.1.8.tar.gz # web界面日志服务工具包
[root@websrv ~]# tar xvf loganalyzer-4.1.8.tar.gz
- 安装需要的服务实现LAMP架构
# 注意这里的php版本一定要是在5.6版本相同或以上要不这个软件不支持
[root@websrv ~]# yum install httpd php56-php-fpm.x86_64 php56-php-mysqlnd.x86_64 -y
- 把loganalyzer需要的目录切到网站目录下
[root@websrv loganalyzer-4.1.8]# ll
total 100
drwxrwxr-x 13 root root 4096 Sep 26 23:41 src

drwxrwxr-x 13 root root 4096 Sep 26 23:41 log
# 修改所有者为apache
[root@websrv loganalyzer-4.1.8]# cd /var/www/html/
[root@websrv html]# chown -R apache.apache log/
- 修改httpd配置文件支持php-fpm
# 添加index.php
DirectoryIndex index.php index.html
# 找到这个模块位置,添加中间三行内容。
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
- 创建调用模块文件(或者理解为反向代理)
[root@websrv html]# vim /etc/httpd/conf.d/fcgi.conf
Directoryindex index.php
Proxyrequests off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1
第4、5这两项的配置在centos7上要加。centos8是默认配置好的不用修改。
[root@websrv html]# cd log/
[root@websrv log]# pwd
/var/www/html/log
[root@websrv log]# touch config.php # 创建这个文件
[root@websrv log]# chmod 666 config.php # 给这个文件所有人可读和可写权限(根据工作需求更改)
[root@centos7 ~]$mysql
