简单搭建zookeeper集群分布式/伪分布式

分布式搭建

一、下载zookeeper安装包

自行下载：我用的是 zookeeper-3.5.4-beta.tar.gz

二、环境准备

1、 我的虚拟机自带的java是1.7的，这个版本要求java1.8的版本，因此又下载了java1.8，进行了环境变量配置

2、我准备了三台虚拟机，分别为192.168.48.101    、192.168.48.102  和     192.168.48.103

3、上传zookeeper包到101机器。并在zookeeper目录进行解压

三、简单配置

在conf目录下，通过zoo_sample.cfg复制了一个zoo.cfg

cp zoo_sample.cfg zoo.cfg 

在zoo.cfg配置信息，如下：

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/dataLogs
clientPort=2181
server.1=192.168.48.101:2888:3888
server.1=192.168.48.102:2888:3888
server.1=192.168.48.103:2888:3888

在zookeeper目录创建了myid  >>  1

使用scp命，将zookeeper配置后的包，传到102、103机器

分别在102、103修该myid   >>  2、3

配置了zookeeper环境变量

export ZOOKEEPER_HOME=/opt/zookeeper/zookeeper354
export PATH=$PATH:$ZOOKEEPER_HOME/bin

四、测试

分别启动三台机器  zkServer.sh start

[root@centos01 conf]# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[root@centos02 zookeeper]# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[root@centos03 conf]# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

分别查看三台机器状态

[root@centos01 conf]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: follower

[root@centos02 conf]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: leader

[root@centos03 conf]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/zookeeper354/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: follower

伪分布式搭建

/zkServer.sh start /opt/zookeeper/zookeeper-3.4.5/conf/zoo3.cfg

/zkServer.sh start /opt/zookeeper/zookeeper-3.4.5/conf/zoo2.cfg

/zkServer.sh start /opt/zookeeper/zookeeper-3.4.5/conf/zoo1.cfg

/zkServer.sh status /opt/zookeeper/zookeeper-3.4.5/conf/zoo3.cfg

/zkServer.sh status /opt/zookeeper/zookeeper-3.4.5/conf/zoo2.cfg

/zkServer.sh status /opt/zookeeper/zookeeper-3.4.5/conf/zoo1.cfg

kafka-server-start.sh /opt/kafka/config/server3.properties & kafka-server-start.sh /opt/kafka/config/server2.properties & kafka-server-start.sh /opt/kafka/config/server1.properties &
