3 ZooKeeper

3.1 节点分配

ZooKeeperServer :

master002,master003, master004, master005, master006

ZooKeeperClient :

master001,master002, master003, master004, master005, master006

3.2 安装

ZooKeeper Client节点:

yum install -y zookeeper

ZooKeeper Server节点:

yum install -y zookeeper-server

3.3 配置

1.zookeeper节点改动zookeeper配置文件

/etc/zookeeper/conf/zoo.cfg

maxClientCnxns=50

# 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

server.2=master002:2888:3888

server.3=master003:2888:3888

server.4=master004:2888:3888

server.5=master005:2888:3888

server.6=master006:2888:3888

2.初始化节点

master002:

service zookeeper-server init --myid=2

master003:

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.执行zookeeper

service zookeeper-server start

3.4 安装路径

程序路径

/usr/lib/zookeeper/

配置文件路径

/etc/zookeeper/conf

日志路径

/var/log/zookeeper

3.5 执行|关闭|查看状态

ZooKeeper

service zookeeper-server start|stop|status

3.6 经常使用命令

查看ZooKeeper节点状态

zookeeper-server status

手动清理日志

/usr/lib/zookeeper/bin/zkCleanup.shdataLogDir [snapDir] -n count

自己主动清理日志

autopurge.purgeInterval 这个參数指定了清理频率，单位是小时，须要填写一个1或更大的整数，默认是0，表示不开启自己清理功能。

autopurge.snapRetainCount 这个參数和上面的參数搭配使用，这个參数指定了须要保留的文件数目。默认是保留3个。
