一.kafka启动报如下错误，或者 启动消费者和生产者报如下错误 

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

解决方法：

下载slf4j-1.7.6.zip

解压
unzip slf4j-1.7.6.zip

把slf4j-nop-1.7.6.jar 包复制到kafka libs目录下面
cd  slf4j-1.7.6
cp slf4j-nop-1.7.6.jar  /export/kafka/libs/
