kafka啟動後，會産生會多日志，經常會将磁盤撐爆。是以kafka日志清理很有必要
log4j.properties
該檔案為kafka日志管理的配置檔案，位于$KAFKA_HOME/config/log4j.properties
預設該配置檔案中日志存放路徑為$KAFKA_HOME/logs，可以修改為其他容量較大的資料盤，比如我自己設定為/data/kafka/logs
注意：如果隻是改了這個配置，是不生效的，還需要修改腳本$KA_FKA_HOME/bin/kafka-run-class.sh，加入以下配置
1
<code>LOG_DIR=</code><code>"/data/kafka/logs"</code>
log4j.properties配置
