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 [[email protected] ~]$hostname rsyslog [[email protected] ~]$exit [[email protected] ~]$ # 数据库服务器 [[email protected] ~]$hostname mysql [[email protected] ~]$exit [[email protected] ~]$ # websrv服务器 [[email protected] ~]# hostname websrv [[email protected] ~]# exit [[email protected] ~]$
日志服务器：
- 在rsyslog服务器上安装连接mysql模块相关的程序包
[[email protected] ~]$yum install rsyslog-mysql -y
- 找到sql脚本发送到数据库
# 下载辅助软件查找
[[email protected] ~]$yum install mlocate
[[email protected] ~]$updatedb # 更新数据库信息
[[email protected] ~]$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
[[email protected] ~]$cat /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql # 脚本文件内容

- 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[[email protected] ~]#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 $ModLoad ommysql
数据库服务器：
1.安装数据库
[[email protected] ~]$yum install mariadb-server -y [[email protected] ~]$systemctl start mariadb.service
2.执行考过来的脚本
[[email protected] ~]$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/ [[email protected] ~]$mysql < mysql-createDB.sql # 直接导入数据库
3.创建Syslog库使用的账号
[[email protected] ~]$mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 3 Server version: 5.5.60-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]> grant all on Syslog.* to [email protected]‘192.168.39.%‘ identified by ‘taotaobao‘; # 注意这里的数据库名要对应执行的sql脚本里的数据库名。 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
[[email protected] ~]$systemctl restart rsyslog.service [[email protected] ~]$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：
1.解压缩工具
[[email protected] ~]# 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 [[email protected] ~]# tar xvf loganalyzer-4.1.8.tar.gz
2.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 [[email protected] ~]# yum install httpd php56-php-fpm.x86_64 php56-php-mysqlnd.x86_64 -y
3.把loganalyzer需要的目录切到网站目录下
[[email protected] loganalyzer-4.1.8]# ll total 100 drwxrwxr-x 13 root root 4096 Sep 26 23:41 src -rw-rw-r-- 1 root root 48571 Sep 26 23:41 ChangeLog drwxrwxr-x 2 root root 43 Sep 26 23:41 contrib -rw-rw-r-- 1 root root 35497 Sep 26 23:41 COPYING drwxrwxr-x 3 root root 258 Sep 26 23:41 doc -rw-rw-r-- 1 root root 8449 Sep 26 23:41 INSTALL [[email protected] loganalyzer-4.1.8]# mv src/ /var/www/html/log # 切到网站目录下 [[email protected] loganalyzer-4.1.8]# ll /var/www/html/ total 4 drwxrwxr-x 13 root root 4096 Sep 26 23:41 log # 修改所有者为apache [[email protected] loganalyzer-4.1.8]# cd /var/www/html/ [[email protected] html]# chown -R apache.apache log/
4.修改httpd配置文件支持php-fpm
# 添加index.php
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
5.web界面测试
- 进行检测
- 这里如果错了可能会显示没有用于写的文件
- 解决方法（是缺少这个文件导致的）
[[email protected] html]# cd log/ [[email protected] log]# pwd /var/www/html/log [[email protected] log]# touch config.php # 创建这个文件 [ro[email protected] 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）
- 这些信息是最后显示的日志格式是什么样的
- 填写数据库的信息
- 查看添加的表名
[[email protected] ~]$mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 8 Server version: 5.5.60-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]> use Syslog; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed MariaDB [Syslog]> show tables; +------------------------+ | Tables_in_Syslog | +------------------------+ | SystemEvents | # 这个表是作为存储日志信息使用的 | SystemEventsProperties | +------------------------+ 2 rows in set (0.00 sec)
- 成功
- 查看报告书界面（但是没有饼状图不清晰）
[[email protected] html]# yum install php56-php-gd.x86_64 -y # 支持画饼状图的包 [[email protected] html]# systemctl restart httpd.service php56-php-fpm.service # 重启服务
- 刷新web界面(这样就会产生比较清晰的饼状图)
