1??????集群環境
主節點
master001 ~~ master006
從節點
slave001 ~~ slave064
2??????安裝CDH5的YUM源
rpm -Uvhhttp://archive.cloudera.com/cdh5/one-click-install/redhat/6/x86_64/cloudera-cdh-5-0.x86_64.rpm
或

ZooKeeperClient :
master001,master002, master003, master004, master005, master006
?
3.2????安裝
ZooKeeper Client節點:
yum install -y zookeeper
ZooKeeper Server節點:
yum install -y zookeeper-server
3.3????配置
1.zookeeper節點改動zookeeper配置文件
/etc/zookeeper/conf/zoo.cfg

# Thenumber of milliseconds of each tick
tickTime=2000
# Thenumber of ticks that the initial
#synchronization phase can take
initLimit=10
# Thenumber of ticks that can pass between
# sendinga request and getting an acknowledgement
syncLimit=5
# thedirectory where the snapshot is stored.
dataDir =/data/disk01/zookeeper/zk_data
dataLogDir =/data/disk01/zookeeper/zk_log
# theport at which the clients will connect
clientPort=2181

service zookeeper-server init --myid=3
master004:
service zookeeper-server init --myid=4
master005:
service zookeeper-server init --myid=5
master006:
service zookeeper-server init --myid=6
3.執行zookeeper
service zookeeper-server start
?
3.4????安裝路徑
程序路徑
/usr/lib/zookeeper/
配置文件路徑
/etc/zookeeper/conf
日志路徑
/var/log/zookeeper
3.5????執行|關閉|查看狀態
ZooKeeper
service zookeeper-server start|stop|status
?
3.6????經常使用命令
查看ZooKeeper節點狀態
zookeeper-server status
?
手動清理日志
/usr/lib/zookeeper/bin/zkCleanup.shdataLogDir [snapDir] -n count
自己主動清理日志
autopurge.purgeInterval 這個參數指定了清理頻率，單位是小時，須要填寫一個1或更大的整數，默認是0，表示不開啟自己清理功能。
autopurge.snapRetainCount 這個參數和上面的參數搭配使用，這個參數指定了須要保留的文件數目。默認是保留3個。

# Thedefault log rolling policy is RFA, where the log file is rolled as per the sizedefined for the
# RFAappender. Please refer to the log4j.properties file to see more details on thisappender.
# In caseone needs to do log rolling on a date change, one should set the environmentproperty
#HBASE_ROOT_LOGGER to "<DESIRED_LOG LEVEL>,DRFA".
# Forexample:
#HBASE_ROOT_LOGGER=INFO,DRFA
# Thereason for changing default to RFA is to avoid the boundary case of filling outdisk space as
# DRFAdoesn't put any cap on the log size. Please refer to HBase-5655 for morecontext.
