修改Zookeeper日志输出路径，并按照日期输出

1、修改log4j.properties

vi  /opt/zookeeper-3.4.8/conf/log4j.properties
# Define some default values that can be overridden by system properties
zookeeper.root.logger=INFO,ROLLINGFILE 

zookeeper.console.threshold=INFO

zookeeper.log.dir=.
zookeeper.log.file=zookeeper.log

zookeeper.log.threshold=DEBUG

zookeeper.tracelog.dir=.

zookeeper.tracelog.file=zookeeper_trace.log

…

…

#

# Add ROLLINGFILE to rootLogger to get log file output

#    Log DEBUG level and above messages to a log file
# 按照日期每天输出logs
log4j.appender.ROLLINGFILE=org.apache.log4j.DailyRollingFileAppender

log4j.appender.ROLLINGFILE.Threshold=${zookeeper.log.threshold}

log4j.appender.ROLLINGFILE.File=${zookeeper.log.dir}/${zookeeper.log.file}

# Max log file size of 10MB
#log4j.appender.ROLLINGFILE.MaxFileSize=10MB

# uncomment the next line to limit number of backup files

#log4j.appender.ROLLINGFILE.MaxBackupIndex=10

…

…

2、修改zkEnv.sh
vi  /opt/zookeeper-3.4.8/bin/zkEnv.sh
I…

…

if [ -f "$ZOOCFGDIR/java.env" ]

then

    . "$ZOOCFGDIR/java.env"

fi

if [ "x${ZOO_LOG_DIR}" = "x" ]

then
#日志输出路径 不需mkdir zookeeper启动时自动创建

    ZOO_LOG_DIR="/opt/zookeeper-3.4.8/logs"

fi

if [ "x${ZOO_LOG4J_PROP}" = "x" ]

then

    ZOO_LOG4J_PROP="INFO,ROLLINGFILE"

fi

if [ "$JAVA_HOME" != "" ]; then

  JAVA="$JAVA_HOME/bin/java"

else

  JAVA=java

fi

…

…

输出的格式为:zookeeper.log

前一天日志的输出格式为:zookeeper.log.2016-09-01
