1. 进入zookeeper安装目录下修改log4j.properties文件内容如下：
cd /opt/zookeeper/zookeeper-3.4.13/conf
#修改
zookeeper.log.dir=../logs
#增加
log4j.appender.DAYROLLINGAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DAYROLLINGAppender.DatePattern='.'yyyy-MM-dd-HH
log4j.appender.DAYROLLINGAppender.File=${zookeeper.log.dir}/${zookeeper.log.file}
log4j.appender.DAYROLLINGAppender.Threshold=INFO
log4j.appender.DAYROLLINGAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.DAYROLLINGAppender.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] - %m%n
2. 修改zkEnv.sh 环境变量
vim /opt/zookeeper/zookeeper-3.4.13/bin/zkEnv.sh
if [ "x${ZOO_LOG_DIR}" = "x" ]
then
ZOO_LOG_DIR="$ZOOBINDIR/../logs"
fi
if [ "x${ZOO_LOG4J_PROP}" = "x" ]
then
ZOO_LOG4J_PROP="INFO,DAYROLLINGAppender"
fi
