前言
LogAnalyzer 是一款syslog日志和其他网络事件数据的Web前端
Adiscon LogAnalyzer is a web interface to syslog and other network event data. It provides easy browsing, analysis of realtime network events and reporting services.
对于任何一个系统而言，日志都是致关重要的，通过日志，系统管理员可以查看系统的运行状况，开发人员可以快速定位问题、分析问题
当系统或应用很分散时，日志就会很分散，给日志分析带来一定不便，awk，sed，grep 等工具的局限性愈发明显，ELK 可以很好解决这个问题，感兴趣可以参考之前的 ELK 搭建 ，ELK 可以高效且有针对性地解决这类问题，同时也有其复杂度和相应的基础开销，有时对于一套相对较小的系统用起来会有点重，这时使用系统自带的 rsyslog 结合 LogAnalyzer 就可以很方便的满足需求
这里分享一下使用 loganalyzer、rsyslog、mysql、apache 搭建一个简单日志服务器的操作过程，详细可以参考 David Tang 的 CentOS 6.5下利用Rsyslog LogAnalyzer MySQL部署日志服务器 (这篇文章准确来说不算原创，是参考他博客的一次实践) 和 官方文档
Tip: 当前的 LogAnalyzer 最新版本为 LogAnalyzer v4.1.3 (v4-beta) ，最新稳定版为 LogAnalyzer v3.6.6 (v3-stable)
