安装步骤：

1. zookeeper是jdk写的，所以启动需要安装jdk环境

2. 下载zookeeper

wget http://archive.apache.org/dist/zookeeper/zookeeper-3.3.3/zookeeper-3.3.3.tar.gz

 

3. 解压

tar zxvf zookeeper-3.3.3.tar.gz

 

4. 进入到zookeeper目录下，将conf下的模板配置文件复制一份，并重命名

cp conf/zoo_sample.cfg conf/zoo.cfg

 

5. 编辑zoo.cfg 文件

vi conf/zoo.cfg

内容为如下：

# 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.
dataDir=/root/zookeeper-3.3.3/data         #这里的目录为zookeeper的安装目录下
# the port at which the clients will connect
clientPort=2181

 

6. zookeeper安装目录下新建data文件夹

mkdir data

 

7. 在bin目录下，启动zookeeper

./bin/zkServer.sh start

挂起进程启动

nohup ./bin/zkServer.sh start &

8. 停止zookeeper

./bin/zkServer.sh stop
