为什么tomcat7同时登录catalina.out和catalina.YYYY-MM-DD.log？

Question

在OpenBSD 5.2，Tomcat的7.0.29默认安装的似乎是记录所有的错误到两个catalina.out及catalina.YYYY-MM-DD.log。

（请注意 的总文件大小与catalina.YYYY-MM-DD.log大致相同catalina.out，并且日志确实似乎重复。）

有没有办法让它只登录catalina.YYYY-MM-DD.log而不登录catalina.out？

Answer 1

在http://tomcat.apache.org/tomcat-7.0-doc/logging.html阅读了一些信息后，似乎注释掉或删除所有提到的java.util.logging.ConsoleHandlerfrom/etc/tomcat/logging.properties应该可以解决问题。

在那之后，不知何故该文件仍然被 tomcat（asstdout和stderr）打开以供写入，但它似乎不再有任何东西了。
