此文是基于上一篇文章:hadoop集群搭建

安装zookeeper:

【在各个slave节点安装zookeeper】

下载地址:http://mirror.bit.edu.cn/apache/zookeeper/

zk节点最好是奇数个,这样子方便在节点中选取leader节点;

上传zookeeper-3.4.10的安装包到/software目录下:

tar -zxvf zookeeper-3.4..tar.gz 

解压到/software下;
进入zookeeper-3.4.10创建文件夹data;

mkdir -p /software/zookeeper-3.4./data

在data下创建文件myid,内容是1;

echo "">>/software/zookeeper-3.4./data/myid

进入conf,复制一份zoo_sample.cfg命名为zoo.cfg;

cp zoo_sample.cfg zoo.cfg

修改zoo.cfg内容:

dataDir=/software/zookeeper-3.4./data
#这里是zookeeper快照目录,建议根据实际修改

最后一行添加:

格式:server.serverId=hostname:lfPort:txPort

# serverId是zk节点的ID编号

# hostname是主机名

# lfPort是leader与follower之间的通信端口(默认2888)

# txPort是follower之间选举leader的通信端口(默认3888)

server.=slave01::3888   #server.1中的1是id,后面是主机名和端口号
server.=salve02::
server.=slave03::3888

然后将zookeeper-3.4.10文件夹的权限改成hadoop;

chown -R hadoop:hadoop /software/zookeeper-3.4.

其它节点安装只需要将整个zookeeper-3.4.10目录拷贝到其它节点相同的文件夹/software下面,并且修改data下的myid文件,修改为各自的id:

scp -r hadoop1:/hadoop/zookeeper
echo "2">/software/zookeeper-3.4.10/data/myid

为了方便可以将zookeeper的可执行文件目录添加到PATH环境变量中:

PATH=/software/zookeeper-3.4./bin;

分别在每个节点上/software/zookeeper-3.4.10/bin目录下

启动 ./zkServer.sh start;

linux安装配置zookeeper-3.4.10

查看启动状态 ./zkServer.sh status

linux安装配置zookeeper-3.4.10

停止 ./zkServer.sh stop

linux安装配置zookeeper-3.4.10

利用jps查看进程会多出:QuorumPeerMain

使用zkCli.sh -server IP:PORT来连接zookeeper集群,具体语法如下:

zkCli.sh -server 127.0.0.1:

使用help查看相关帮助;
