下载压缩包

        从 此地址 下载zookeeper-xxx.tar.gz    注意：从目前的最新版本3.5.5开始，带有bin名称的包才是我们想要的下载可以直接使用的里面有编译后的二进制的包，而之前的普通的tar.gz的包里面是只是源码的包无法直接使用。，如果下载3.5.5以后的版本的Zookeeper安装包，需下载带有bin标识的。

解压

> tar -zxvf zookeeper-3.5.6.tar.gz //解压
> cd zookeeper-3.5.6/conf //切换到配置目录下
> mv zoo_sample.cfg zoo.cfg //更改默认配置文件名称
> vi zoo.cfg //编辑配置文件，自定义dataDir

启动Server

> cd zookeeper-3.4.10/bin //切换到 bin目录
> ./zkServer.sh start //启动
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /Users/admin/zookeeper/apache-zookeeper-3.5.6/bin/../conf/zoo.cfg
Starting zookeeper ... FAILED TO START

问题原因：

   需要下载带有bin的文件

解决过程：

查看启动状态：

admindeMac-mini-2:bin admin$ ./zkServer.sh status
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /Users/admin/zookeeper/apache-zookeeper-3.5.6/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Error contacting service. It is probably not running.

查看报错日志

admindeMac-mini-2:bin admin$ ./zkServer.sh start-foreground
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /Users/admin/zookeeper/apache-zookeeper-3.5.6/bin/../conf/zoo.cfg
错误: 找不到或无法加载主类 org.apache.zookeeper.server.quorum.QuorumPeerMain

重新下载带有bin的文件后成功运行

 

客户端连接：
