...
1catalina.org.apache.juli.FileHandler.maxDays = 7
...
2localhost.org.apache.juli.FileHandler.maxDays = 7

4host-manager.org.apache.juli.FileHandler.maxDays = 7

或者自己加个 crontab 定时任务，执行：

find ${YOUR_TOMCAT_PATH}/logs -mtime +7 -name '*.log' -exec rm -rf {} \;

内置日志本身没有切割功能，所以你那个最大 100MB 的需求需要引入其他工具，比如 cronolog 或者 logrotate 之类的，具体用法自己搜一下吧。
