1.安装zookeeper单机模式

配置java环境

[root@zookeeper ~]# wget https://www.reucon.com/cdn/java/jdk-8u45-linux-x64.tar.gz
[root@zookeeper ~]# tar xf jdk-8u45-linux-x64.tar.gz
[root@zookeeper ~]# cp -r jdk1.8.0_45 /usr/local/
[root@zookeeper ~]# cat /etc/profile.d/java.sh
JAVA_HOME=/usr/local/jdk1.8.0_45
JAVA_BIN=/usr/local/jdk1.8.0_45/bin
JRE_HOME=/usr/local/jdk1.8.0_45/jre
PATH=$PATH://usr/local/jdk1.8.0_45/bin:/usr/local/jdk1.8.0_45/jre/bin
CLASSPATH=/usr/local/jdk1.8.0_45/jre/lib:/usr/local/jdk1.8.0_45/lib:/usr/local/jdk1.8.0_45/jre/lib/charsets.jar
[root@zookeeper ~]# source /etc/profile.d/java.sh
[root@zookeeper ~]# java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

下载软件包

[root@zookeeper ~]# wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

安装

[root@zookeeper ~]# tar xf zookeeper-3.4.6.tar.gz -C /usr/local/
[root@zookeeper ~]# ln -s /usr/local/zookeeper-3.4.6/ /usr/local/zookeeper
[root@zookeeper conf]# pwd
/usr/local/zookeeper/conf
[root@zookeeper conf]# cp zoo_sample.cfg zoo.cfg

#修改配置文件
[root@zookeeper conf]# egrep -v "^#|^$" /usr/local/zookeeper/conf/zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/build
clientPort=2181
dataLogDir=/data/zookeeper/logs
#tickTime: 这个时间是作为Zookeeper服务器之间或客户端与服务器之间维持心跳的时间间隔, 也就是每个tickTime时间就会发送一个心跳
#dataDir: 顾名思义就是Zookeeper保存数据的目录, 默认情况下, Zookeeper将写数据的日志也保存在这个目录里
#clientPort: 这个端口就是客户端连接Zookeeper服务器的端口, Zookeeper会监听这个端口, 接受客户端的访问请求

启动zookeeper

[root@zookeeper ~]# /usr/local/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

#查看结果
[root@zookeeper ~]# netstat -tunlp |grep 2181
tcp        0      0 :::2181                     :::*                        LISTEN      1444/java

2.安装zookeeper集群

zookeeper-1    192.168.3.19

zookeeper-2    192.168.3.20

zookeeper-1操作:

#停止zookeeper服务
[root@zookeeper ~]# /usr/local/zookeeper/bin/zkServer.sh stop
JMX enabled by default
Using config: /usr/local/zookee

#修改配置文件/usr/local/zookeeper/conf/zoo.cfg
[root@zookeeper ~]# egrep -v "^$|^#" /usr/local/zookeeper/conf/zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/build
clientPort=2181
dataLogDir=/data/zookeeper/logs
server.1 = 192.168.3.19:2888:3888
server.2 = 192.168.3.20:2888:3888

#配置myid
[root@zookeeper ~]# cat /data/zookeeper/build/myid 
1

zookeeper-2需要安装java和zookeeper，过程请看上文

#配置文件内容如下
[root@zookeeper-2 conf]# egrep -v "^$|^#" /usr/local/zookeeper/conf/zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/build
clientPort=2181
dataLogDir=/data/zookeeper/logs
server.1 = 192.168.3.19:2888:3888
server.2 = 192.168.3.20:2888:3888

#启动服务
[root@zookeeper-2 ~]# /usr/local/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

最后验证集群状态

#zookeeper-1
[root@zookeeper ~]# /usr/local/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: leader

#zookeeper-2
[root@zookeeper-2 ~]# /usr/local/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower

通过客户端脚本验证

[root@zookeeper ~]# /usr/local/zookeeper/bin/zkCli.sh
[zk: localhost:2181(CONNECTED) 2] ls /
[zookeeper]                # 第一次部署Zookeeper集群，默认创建名为/zookeeper的节点
