zookeeper安装部署

hdfg

1.安装zookeeper单机模式
配置java环境

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[iyunv@zookeeper ~]# wget https://www.reucon.com/cdn/java/jdk-8u45-linux-x64.tar.gz [iyunv@zookeeper ~]# tar xf jdk-8u45-linux-x64.tar.gz [iyunv@zookeeper ~]# cp -r jdk1.8.0_45 /usr/local/ [iyunv@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 [iyunv@zookeeper ~]# source /etc/profile.d/java.sh [iyunv@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

1	[iyunv@zookeeper ~]# wget http://mirrors.hust.edu.cn/apach ... keeper-3.4.6.tar.gz

安装

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

[iyunv@zookeeper ~]# tar xf zookeeper-3.4.6.tar.gz -C /usr/local/ [iyunv@zookeeper ~]# ln -s /usr/local/zookeeper-3.4.6/ /usr/local/zookeeper [iyunv@zookeeper conf]# pwd /usr/local/zookeeper/conf [iyunv@zookeeper conf]# cp zoo_sample.cfg zoo.cfg #修改配置文件 [iyunv@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

1 2 3 4 5 6 7 8

[iyunv@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 [iyunv@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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#停止zookeeper服务 [iyunv@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 [iyunv@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 [iyunv@zookeeper ~]# cat /data/zookeeper/build/myid 1

zookeeper-2需要安装java和zookeeper，过程请看上文

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#配置文件内容如下 [iyunv@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 [iyunv@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

1 2 3 4 5 6 7 8 9 10 11

#zookeeper-1 [iyunv@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 [iyunv@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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78
