场景：生产环境可集中式分析特定日志，便于管理，以及快速解决程序问题等。
常见：nginx、apache的访问日志，错误日志 catalina.out日志等。可以把错误日志提取出并解决。
安装方式：
1）编译安装 常用组合 ELK+Reids+插件
1.1）优点：方便管理
1.2）缺点：需要手动安装配置，相对yum繁琐
2）yum安装
2.1）优点：安装配置方便
2.2）缺点：相对编译不太好管理（依赖关系等因素）
My eg：
注意事项：elk安装比较简单，但是要注意最低配置。这里我个人用的是编译安装，并且自己写的脚本。yum安装脚本可直接用。

启动：logstash -f catalinalog.conf （测试）
