这时要更改logs的默认目录，指向更大的磁盘。修改主要有两步：
1. 修改tomcat/conf下的logging.properties
############################################################ # Handler specific properties. # Describes specific configuration info for Handlers. ############################################################ 1catalina.org.apache.juli.FileHandler.level = FINE 1catalina.org.apache.juli.FileHandler.directory = /diska/tomcatlog/logs 1catalina.org.apache.juli.FileHandler.prefix = catalina. 2localhost.org.apache.juli.FileHandler.level = FINE 2localhost.org.apache.juli.FileHandler.directory = /diska/tomcatlog/logs 2localhost.org.apache.juli.FileHandler.prefix = localhost. 3manager.org.apache.juli.FileHandler.level = FINE 3manager.org.apache.juli.FileHandler.directory = /diska/tomcatlog/logs 3manager.org.apache.juli.FileHandler.prefix = manager. 4host-manager.org.apache.juli.FileHandler.level = FINE 4host-manager.org.apache.juli.FileHandler.directory = /diska/tomcatlog/logs 4host-manager.org.apache.juli.FileHandler.prefix = host-manager. java.util.logging.ConsoleHandler.level = FINE java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter ############################################################
把其中各个directory路径更改为要存储对应日志的路径，一般都是设置为同一个地方。
2. 修改tomcat/bin/catalina.sh
if [ -z "$CATALINA_OUT" ] ; then 179 CATALINA_OUT=/diska/tomcatlog/logs/catalina.out
把CATALINA_OUT修改为与logging.properties修改一样的路径，便于日志集中管理。
重启tomcat就能看到diska/tomcatlog/logs/下开始产生新日志了。
