篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了zookeeper集群部署相关的知识,希望对你有一定的参考价值。

前提:关闭防火墙
1、解压
cd /opt/module/
tar -zxvf apache-zookeeper-3.5.5-bin.tar.gz
2、创建数据文件和目录文件
在zookeeper的跟目录下创建两个文件夹data和log
cd /opt/module/apache-zookeeper-3.5.5-bin/
mkdir data
mkdir log
3、拷贝配置文件
cd /opt/module/apache-zookeeper-3.5.5-bin/conf/
cp zoo_sample.cfg zoo.cfg
配置文件更改

The number of milliseconds of each tick

tickTime=2000

The number of ticks that the initial

synchronization phase can take

initLimit=10

The number of ticks that can pass between

sending a request and getting an acknowledgement

syncLimit=5

the directory where the snapshot is stored.

do not use /tmp for storage, /tmp here is just

example sakes.

dataDir=/opt/module/apache-zookeeper-3.5.5-bin/data
dataLogDir=/opt/module/apache-zookeeper-3.5.5-bin/log

the port at which the clients will connect

clientPort=2181

the maximum number of client connections.

increase this if you need to handle more clients

#maxClientCnxns=60

Be sure to read the maintenance section of the

administrator guide before turning on autopurge.

http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

Purge task interval in hours

Set to “0” to disable auto purge feature

#autopurge.purgeInterval=1
server.0=192.168.1.100:2888:3888
server.1=192.168.1.101:2888:3888
server.2=192.168.1.102:2888:3888
4、创建服务器myid
在data目录下创建一个myid的文件,里面的值可以给个任意的值,但要和上述服务起server.x对应
cd /opt/module/apache-zookeeper-3.5.5-bin/data/
touch myid

5、集群拷贝
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop101:/opt/module/apache-zookeeper-3.5.5-bin
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop102:/opt/module/apache-zookeeper-3.5.5-bin
6、集群myid更改
进入到每个节点,修改myid值
集群系统环境变量添加:vi /etc/profile
export ZOOKEEPER_HOME=/opt/module/apache-zookeeper-3.5.5-bin
export PATH= P A T H : PATH: PATH:ZOOKEEPER_HOME/bin
保存系统环境变量:source /etc/profile
关闭集群防火墙
7、集群启动
进入到每个节点启动
cd /opt/module/apache-zookeeper-3.5.5-bin
zkServer.sh start
zkServer.sh status

zkCli连接验证
zkCli.sh -server hadoop100:2181
