CentOS 7.0安装zookeeper3.4.11

环境

CentOS 7

hadoop 2.7.3 CentOS 7.0安装flume

zookeeper 3.4.11

下载zookeeper

下载链接：https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/

百度云下载链接：https://pan.baidu.com/s/1nuDb1R7 密码：ekj2

配置

上传的到集群机器上

本例中我放在了 /data/software 目录下

新建目录 解压

mkdir -p /opt/zookeeper/datamkdir -p /opt/zookeeper/log

解压zookeeper

tar -zxvf zookeeper-3.4.11.tar.gz -C /opt/zookeeper/

新建myid文件并添加内容

cd /opt/zookeeper/data# master节点echo 1 >> myid# slave1节点echo 2 >> myid# slave2节点echo 3 >> myid

说明： 在master节点中的myid添加1，在slave1中添加2，在slave2中添加3

修改zookeeper的配置文件

cd /opt/zookeeper/zookeeper-3.4.11/conf/cp zoo_sample.cfg zoo.cfgvi zoo.cfg

注释原来的dataDir,添加新创建的dataDir和dataLogDir目录

dataDir=/opt/zookeeper/datadataLogDir=/opt/zookeeper/log

同时添加以下代码 (格式：server.id=host:port:port)

server.1=master:2888:3888server.2=slave1:2888:3888server.3=slave2:2888:3888

说明：2888和3888都是zookeeper的默认端口号，也可以自己设置。第一个端口号是从服务器(follower)连接主服务器(leader)的端口号,第二个端口号是进行leadership选举的端口号

启动

分别启动zookeeper

cd /opt/zookeeper/zookeeper-3.4.11/bin./zkServer.sh start# 输出ZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfgStarting zookeeper ... STARTED

查看进程

jps# 输出39842 ResourceManager52354 Jps52325 QuorumPeerMain39545 SecondaryNameNode39213 NameNode# 输出4593 QuorumPeerMain4618 Jps45003 DataNode119466 NodeManage# 输出45738 DataNode5339 QuorumPeerMain5371 Jps120396 NodeManager

启动成功

测试

查看集群节点状态

./zkServer.sh status# 输出ZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfgMode: follower# 输出ZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfgMode: leader# 输出ZooKeeper JMX enabled by defaultUsing config: /opt/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfgMode: follower

通过 ./zkServer.sh status 命令可以看到哪个节点是leader，哪些节点是follower

客户端访问

我们已经成功登陆到zookeeper的客户端，测试成功

在CentOS 7下安装Zookeeper

Linux安装zookeeper集群(CentOS7+Zookeeper3.4.10)
