日志文件切割：以分隔割tomcat 的 catalina.out 文件为例子通过调整logrotate 的配置文件存放位置，来取消日志自动轮转的设置。比如存放在/etc/logrotate/tomcatTomcat日志切割dateextcompressnotifemptycrontab配置文件：crontab -e#mv /etc/anacrontab /etc/anacrontab.bak //取消日志自动轮转的设置,建议调整configfile，而不是修改crontab配置文件。

logback-动态修改日志格式
jfqqqqq的博客
07-08 2180
目标 在logback作为日志框架的前提下，实现在代码中动态修改日志输出格式的需求（也许没什么用，不过可以在自己的程序启动时达到类似sprinboot的banner那样的效果-springboot的banner是没有日志的类名、时间戳之类的前缀的）。 这里以‘定义一个自己的logger，在输出时不带任何前缀，只输出内容的日志格式，然后后续的所有日志再带上前缀’为目标，进行操作。 实现 知识点 0. 一个日志文件只能被一个appender使用，如果有多个配置appender指向同一个，最终会使用其中
