Ubuntu 13 Zookeeper 集群配置

一．目标

在Linux集群搭建Zookeeper集群，并配置管理Web管理系统。

二．先决条件

本文档中基于VirtualBox Ubuntu Server 13.04 虚机（启动SSH服务器）构建。

三．安装 Zookeeper环境

l 下载jdk-7u51-linux-x64.gz （预先下载到局域网环境）

l cpsing@Zookeeper-Cluster1:~# wget ftp://192.168.1.104/jdk-7u51-linux-x64.gz

l cpsing@Zookeeper-Cluster1:~# sudo cp jdk-7u51-linux-x64.gz /usr/local/

l cpsing@Zookeeper-Cluster1:sudo /usr/local# tar zxvf jdk-7u51-linux-x64.gz

l cpsing@Zookeeper-Cluster1:/usr/local/jdk1.7.0_51$ sudo vi /etc/profile

l 增加如下

export JAVA_HOME=/usr/local/jdk1.7.0_51

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

l cpsing@Zookeeper-Cluster1:/usr/local/jdk1.7.0_51$ source /etc/profile

l cpsing@Zookeeper-Cluster1:/usr/local/jdk1.7.0_51$ java -version

l cpsing@Zookeeper-Cluster1:/usr/local$ sudo wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

l cpsing@Zookeeper-Cluster1:/usr/local$ sudo tar zxvf zookeeper-3.4.6.tar.gz

l cpsing@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6$ sudo vi /etc/environment

export ZOOKEEPER_HOME=/usr/local/zookeeper-3.4.6

export PATH=$PATH:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf

l cpsing@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/conf$ cp zoo_sample.cfg zoo.cfg

dataDir=/root/zookeeper

l cpsing@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/conf$ sudo mkdir /root/zookeeper

l root@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/bin# ./zkServer.sh start

l root@Zookeeper-Cluster1:/etc/init.d# ps -ef | grep 'zookeeper'

四．执行VM Clone

Clone两台VM，如果出现网卡不能使用的情况，则按如下操作：

l 删除 /etc/udev/rules.d/70-persistent-net.rules

l 重启机器

l 修改/etc/hosts：sudo vi /etc/hosts，然后修改 /etc/hostname

五．配置集群

l 修改三台服务器的 /etc/hosts

192.168.9.208 Zookeeper-Cluster1

192.168.9.178 Zookeeper-Cluster2

192.168.9.117 Zookeeper-Cluster3

l 修改三台服务器的zookeeper配置文件增加如下；

server.1=Zookeeper-Cluster1:2888:3888

server.2=Zookeeper-Cluster2:2888:3888

server.3=Zookeeper-Cluster3:2888:3888

l 在我们配置的dataDir指定的目录下面，创建一个myid文件，里面内容为一个数字，用来标识当前主机，conf/zoo.cfg文件中配置的server.X中X为什么数字，则myid文件中就输入这个数字，例如：

root@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/bin# echo "1" > /root/zookeeper/myid

root@Zookeeper-Cluster2:/usr/local/zookeeper-3.4.6/bin# echo "2" > /root/zookeeper/myid

root@Zookeeper-Cluster3:/usr/local/zookeeper-3.4.6/bin# echo "3" > /root/zookeeper/myid

l 检查集群状态

root@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/bin# n./zkServer.sh status

如果显示如下：

root@Zookeeper-Cluster3:/usr/local/zookeeper-3.4.6/bin# n./zkServer.sh status

JMX enabled by default

Using config: /usr/local/zookeeper-3.4.6/bin/../conf/zoo.cfg

Error contacting service. It is probably not running.

执行

root@Zookeeper-Cluster1:/usr/local/zookeeper-3.4.6/bin# tail -f zookeeper.out 查看日志

解决办法：

Sudo vi /etc/hosts

注释掉：127.0.0.1 开始的行，重启zookeeper 搞定！
