【转】tomcat logs 目录下各日志文件的含义

原文链接：https://www.cnblogs.com/qlqwjy/p/8036091.html

tomcat每次启动时，自动在logs目录下生产以下日志文件，按照日期自动备份。可以帮助我们更好的找出错误。

一、认识各种目录的作用及记录的信息

目录

1.catalina.日期.log

这个主要是记录tomcat启动时候的信息，类似于我们在eclipse中启动服务的时候在控制台看到的信息。在里面可以看到启动的JVM参数以及操作系统等日志信息。如果没有使用log4j等日志机制，系统的的错误信息与打印语句也在这个日志文件中记录。(linux下所有的日志都在catalina.out中)

例如:
