zookeeper安装

1.查看zk端口号是否被占用

  a.netstat -lntup 2181；

   b.lsof -i:2181;

  c.ps aux | grep 2181;

2.解压安装包

tar -zxvf /home/soft/zookeeper-3.4.9.tar.gz -C /usr/local/tools/zookeeper

3.复制conf文件夹下的zoo_sample.cfg

 a.cp zoo_sample.cfg zoo.cfg

  b.修改文件zoo.cfg：

    dataDir=/usr/local/tools/zookeeper/zookeeper-3.4.9/data

    dataLogDir=/usr/local/tools/zookeeper/zookeeper-3.4.9/logs

4.修改配置文件：vi /etc/profile

export ZOOKEEPER_HOME=/usr/local/tools/zookeeper/zookeeper-3.4.9

export PATH=$ZOOKEEPER_HOME/bin:$PATH

export PATH

5.生效配置文件

source /etc/profile

6.启动zk:./bin/zkServer.sh start;

  重启zk:./bin/zkServer.sh restart;

 查看zk状态：./bin/zkServer.sh status

 停止服务：./bin/zkServer.sh stop

  ps -ef | grep zookeeper;

  kill -9 pid;

  检查是否启动成功：./bin/zkCli.sh -server localhost:2181

  查看日志：tail -100f .//zookeeper.out

7.输入jps命令查看进程

1580 QuorumPeerMain

1601 Jps
