Zookeeper安装

1、下载Zookeeper：wget

wget http://apache.fayea.com/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

2、解压Zookeeper：

tar  -zxvf  zookeeper-3.4.6.tar.gz

3、进入Zookeeper目录：

cd zookeeper-3.4.6/

4、创建目录：

mkdir data logs

5、进入data目录创建myid文件：

vi myid

[root@localhost data]# cat myid
1

6、进入conf目录复制一份配置文件（作为备份）：

cp zoo_sample.cfg  zoo.cfg

7、修改配置文件zoo_sample.cfg：

# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial# synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just# example sakes.dataDir=/root/zookeeper-3.4.6/datadataLogDir=/root/zookeeper-3.4.6/logs# the port at which the clients will connectclientPort=2181# the maximum number of client connections.# increase this if you need to handle more clients#maxClientCnxns=60## Be sure to read the maintenance section of the# administrator guide before turning on autopurge.## http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance## The number of snapshots to retain in dataDir#autopurge.snapRetainCount=3# Purge task interval in hours# Set to "0" to disable auto purge feature#autopurge.purgeInterval=1server.1=172.16.7.1:2888:3888~                             

其中，需要配置的是

dataDir=/root/zookeeper-3.4.6/data
dataLogDir=/root/zookeeper-3.4.6/logs

和

server.1=172.16.7.1:2888:3888

8、配置环境变量：

vi /etc/profile

export ZOOKEEPER_HOME=/root/zookeeper-3.4.6export PATH=$ZOOKEEPER_HOME/bin:$PATH

9、n)使环境变量生效：

source /etc/profile

10、启动/停止/重启命令

zkServer.sh  startzkServer.sh  stopzkServer.sh  restart
