Mac下ZooKeeper环境部署，Linux方法相同

1、首先到官网下载Zookeeper，目前的稳定版本为3.4.9，下载地址。Liniux下可以直接进入/usr目录，使用wget命令直接下载。

 

cd /usr
sudo wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

2、解压下载ZooKeeper-3.4.9.tar.gz包，重命名目录ZooKeeper-3.4.9为ZooKeeper，删除下载的ZooKeeper-3.4.9包；

 

 

sudo tar -xf ZooKeeper-3.4.9.tar.gz
sudo mv ZooKeeper-3.4.9 ZooKeeper
sudo rm -f ZooKeeper-3.4.9.tar.gz

3、修改环境变量，在profile文件的最后部分导出ZooKeeper的安装路径，这里我把ZooKeeper放在了/Library/文件夹下，大家可以随意放置。

 

 

sudo vim /etc/profile
# ZooKeeper配置
export ZOOKEEPER_INSTALL=/Library/ZooKeeper
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin

4、创建ZooKeeper配置文件

 

 

cd ZooKeeper/conf
cp zoo_sample.cfg zoo.cfg

5、执行vim zoo.cfg，修改配置文件内容

 

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper/data
dataLogDir=/tmp/zookeeper/log
# the port at which the clients will connect
clientPort=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

 

6、创建配置中相应的目录

 

 

cd /tmp
mkdir ZooKeeper
cd ZooKeeper
mkdir log
mkdir data

 

7、启动ZooKeeper

 

cd /Library/Zookeeper/bin
./zkServer.sh

8、可以使用ZooKeeper自带的客户端工具zkCli.sh来查看ZooKeeper的节点简历情况，至此ZooKeeper环境部署完成。
