ubuntu12.04下安装zookeeper3.4.5集群环境

1.下载zookeeper-3.4.5或者wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz

2.由于是需要用到集群，先在host中注入

vi /etc/hosts

加上192.168.50.130 sun

192.168.50.131 sun1

192.168.50.131 sun2

3.tar -xzvf zookeeper-3.4.5.tar.gz

cd zookeeper-3.4.5

cp conf/zoo_sample.cfg conf/zoo.cfg

vi conf/zoo.cfg

  修改：dataDir=/home/sun/zookeeper/data

      dataLogDir=/home/sun/zookeeper/log

  添加：

server.1=sun:2888:3888

server.2=sun2:2888:3888

server.3=sun3:2888:3888

maxClientCnxns=100

4.mkdir /home/sun/zookeeper/data,mkdir /home/sun/zookeeper/log

5.echo 1
> /home/ysc/zookeeper/data/myid(此处的1要根据本机在conf/zoo.cfg中server.x的x来写)

echo 2
> /home/ysc/zookeeper/data/myid(此处的2要根据本机在conf/zoo.cfg中server.x的x来写)

echo 3
> /home/ysc/zookeeper/data/myid(此处的3要根据本机在conf/zoo.cfg中server.x的x来写)

6.将zookeeper的地址放到环境变量中

vi
/etc/profile

在最后面输入export zookeeper_home=/home/sun/zookeeper-3.4.5

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

7.分别在每台机器上启动zookeeper，bin/zkServer.sh start

8.然后查看运行状态,bin/zkServer.sh status
