Linux下安装Zookeeper

1.下载 zookeeper :  http://mirror.bit.edu.cn/apache/zookeeper/

2. 解压: tar -zxvf ****  /.../zookeeper

3. 进入config目录 cp zoo_sample.cfg zoo.cfg

4. 修改zoo.cfg配置

# 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=/.../zookeeper/data
dataLogDir=/.../zookeeper/log
# the port at which the clients will connect
clientPort=2181

 5. 添加环境变量

创建一个环境变量ZOOKEEPER并把该环境变量添加到系统路径：

　　vim /etc/profile

 

　　在export PATH语句前添加两行：

　　ZOOKEEPER=/usr/local/zookeeper/zookeeper-3.4.6

　　PATH=$PATH:$ZOOKEEPER/bin

 

　　并执行 source /etc/profile

6. 启动zookeeper  ./zkServer.sh start    停止: ./zkServer.sh stop

root@iZbp160z8sb56y5j9b3ljfZ:/home/zookeeper/zookeeper-3.4.8/bin# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

7. 测试zookeeper  ./zkCli.sh -server 116.62.48.243:2181  

root@iZbp160z8sb56y5j9b3ljfZ:/home/zookeeper/zookeeper-3.4.8/bin# ./zkCli.sh -server 116.62.48.243:2181
