linux下面Zookeeper的单机模式（standalone）

1、下载 zk下载地址 http://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/

我用的是http://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.3.6/

2、下载至本地 然后sz 从本地上传到服务器

sz

ls

tar xvf zookeeper-3.3.6.tar.gz

3、解压后开始配置Zookeeper，进入到配置文件的目录

cd  zookeeper-3.3.6/conf/

将目录下面的 zoo_sample.cfg修改为zoo.cfg，mv zoo_sample.cfg  zoo.cfg，里面的配置不改

如图所示：

 # The number of milliseconds of each tick
 tickTime=
 # The number of ticks that the initial
 # synchronization phase can take
 initLimit=
 # The number of ticks that can pass between
 # sending a request and getting an acknowledgement
 syncLimit=
 # the directory where the snapshot is stored.
 dataDir=/tmp/zookeeper
 # the port at which the clients will connect
 clientPort=  

这些信息都不用去改！

4、启动Zookeeper服务器进程

cd  zookeeper-3.3./
cd bin/
ls
$ ./zkCli.sh -server 127.0.0.1:
 
执行完毕是这样：

Zookeeper Standalone模式就配置完成了

集群的模式 我下次再学习下 然后记录上来！
