CentOS7下搭建日志采集分析系统LogAnalyzer

LogAnalyzer是一款Web界面syslog日志分析工具。它提供了对日志的简单浏览、搜索、基本分析和一些图表报告的功能。数据可以从数据库或一般的syslog文本文件中获取，所以LogAnalyzer不需要改变现有的记录架构。基于当前的日志数据，它可以处理syslog日志消息，Windows事件日志记录，支持故障排除，使用户能够快速查找日志数据

具体步骤如下

1、环境准备

CentOS7.6的服务器一台

IP:192.168.198.132 可以访问互联网，并关闭SELINUX

2、脚本方式完成HTTP PHP MySQL LogAnalyzer的部署

上传脚本及相关文件至/opt目录下

代码语言：javascript复制

cd /opt
tar -zxvf rsyslog_and_loganalyzer.tar.gz 
sh loganalyzer.sh

(图片可放大查看)

其中loganalyzer.sh脚本内容如下

代码语言：javascript复制

[root@localhost opt]# cat loganalyzer.sh 
#!/bin/bash

脚本并非全自动化，需要在执行过程中需要重新设置MySQL的root密码
