Zookeeper学习记录 - linux下安装部署

Zookeeper学习记录 - linux下安装部署

【单机模式】

一、下载

官网下载地址

二、解压

tar  -zxvf  apache-zookeeper-3.6.1-bin.tar.gz

三、配置

新建如下文件夹：

mkdir /tmp/zookeeper/data
mkdir /tmp/zookeeper/log

配置

cp  zoo_sample.cfg  zoo.cfg
vim zoo.cfg

配置以下内容

dataDir=/tmp/zookeeper/data
dataLogDir=/tmp/zookeeper/log

 

四、环境变量

vim /etc/profile

 

export ZOOKEEPER_INSTALL=/usr/local/zk/apache-zookeeper-3.6.1-bin/
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin

 

source profile

 

五、启动

#进入bin目录
cd /usr/local/zk/apache-zookeeper-3.6.1-bin/bin

#启动服务端
./zkServer.sh start

#启动客户端
./zkCli.sh

 

 【集群模式】

基本步骤同 单机模式 

不同点：

一、创建myid

在 dataDir 目录下创建名为 myid 的文件，在文件第一行写上对应的 Server ID。

echo 1 > /tmp/zookeeper/data/myid
echo 2 > /tmp/zookeeper/data/myid
echo 3 > /tmp/zookeeper/data/myid

 

二、配置

# zk-conf
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper/data
dataLogDir=/tmp/zookeeper/log
clientPort=2181
server.1=IP1:2888:3888
server.2=IP2:2888:3888
server.3=IP3:2888:3888

 

三、运行结果

[root@VM-32-88-centos bin]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zk/apache-zookeeper-3.8.0-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: leader

[root@VM-32-32-centos bin]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zk/apache-zookeeper-3.8.0-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: follower

[root@VM-32-38-centos bin]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zk/apache-zookeeper-3.8.0-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: follower

 

【基础命令】

#启动命令：
zkServer.sh start
 
#停止命令：
zkServer.sh stop
 
#重启命令：
zkServer.sh restart
 
#查看集群节点状态：
zkServer.sh status

 

【验证】

[root@VM-32-88-centos bin]# zkCli.sh -server localhost:2181
Connecting to localhost:2181
[zk: localhost:2181(CONNECTED) 0] get /

[zk: localhost:2181(CONNECTED) 1] create /user tom
Created /user
[zk: localhost:2181(CONNECTED) 2] 
[zk: localhost:2181(CONNECTED) 2] get /user
tom
[zk: localhost:2181(CONNECTED) 3] 
[zk: localhost:2181(CONNECTED) 3] get /

[zk: localhost:2181(CONNECTED) 4] get /love
baby
[zk: localhost:2181(CONNECTED) 5]
