Zookeeper安装

环境准备

ZooKeeper服务器是用Java创建的，它运行在JVM之上。需要安装JDK 7或更高版本。

1、上传

将下载的ZooKeeper放到/opt/ZooKeeper目录下

#上传zookeeper alt+p put f:/setup/apache-zookeeper-3.5.6-bin.tar.gz #打开 opt目录 cd /opt #创建zooKeeper目录 mkdir zooKeeper #将zookeeper安装包移动到 /opt/zooKeeper mv apache-zookeeper-3.5.6-bin.tar.gz /opt/zookeeper/

2、解压

将tar包解压到/opt/zookeeper目录下

tar -zxvf apache-ZooKeeper-3.5.6-bin.tar.gz

3 配置启动

1、配置zoo.cfg

进入到conf目录拷贝一个zoo_sample.cfg并完成配置

#进入到conf目录 cd /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/conf/ #拷贝 cp zoo_sample.cfg zoo.cfg

修改zoo.cfg

#打开目录 cd /opt/zooKeeper/ #创建zooKeeper存储目录 mkdir zkdata #修改zoo.cfg vim /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/conf/zoo.cfg

修改存储目录：dataDir=/opt/zookeeper/zkdata

2、启动ZooKeeper

cd /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/bin/ #启动 ./zkServer.sh start

看到上图表示ZooKeeper成功启动

3、查看ZooKeeper状态

./zkServer.sh status

zookeeper启动成功。standalone代表zk没有搭建集群，现在是单节点

zookeeper没有启动
