当禁用tomcat管理页面时，但是在服务器从启动时，在tomcat默认的/aliyun/tomcat7/logs/ 存放日志的目录下依然还会生成关于host-manager，manager的日志文件，他们此时是无用的，所以要禁止自动生成这些日志，所以修改

[root@tomcat04 conf]# cat -n logging.properties |sed -n '33,41p;55,60p'
33 #####tomcat's log youhua by wujianwei 2016-5-10
34 #3manager.org.apache.juli.FileHandler.level = FINE
35 #3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
36 #3manager.org.apache.juli.FileHandler.prefix = manager.

定时清理tomcat 生成的日志：
[root@tomcat01 scripts]# vim /aliyun/scripts/tomcatlogs_clear.sh
#/bin/bash
path=/aliyun/tomcat7/logs
find $path/ -type f -name "tomcat01" -mtime +3|xargs rm -f
find $path/ -type f -name "catalina" -mtime +3|xargs rm -f
find $path/ -type f -name "localhost*" -mtime +3|xargs rm -f
