1.下载zookeeper

下载地址：​​http://mirror.bit.edu.cn/apache/zookeeper/​​

2.安装zookeeper 

2.1上传压缩文件并解压

        这里使用的是CentOS7的操作系统。在root目录下新建一个名为albert的目录，将下载得到的zookeeper-3.4.13.tar.gz文件上传上去。

如图：

进入到该目录下，命令是：

cd    /root/albert

执行解压命令：

tar -zxvf zookeeper-3.4.13.tar.gz

执行移动命令：

mv zookeeper-3.4.13 /usr/local/zookeeper

2.2新建zookeeper配置文件

         Zookeeper需要一个名为zoo.cfg的配置文件，我们解压后，得到的是官方的示例文件，名为zoo_sample.cfg，这个文件在zookeeper根目录的conf子目录下。如果我们想使用默认配置，直接将该文件复制并且改名即可。

进入zookeeper配置文件目录

[root@yxy albert]# cd /usr/local/zookeeper/conf

复制配置文件：

[root@yxy conf]# cp zoo_sample.cfg zoo.cfg

      上面的命令生成了zoo.cfg

      如图：

       更改配置文件：

vi zoo.cfg

2.3配置环境变量

          命令：vi  /etc/profile

[root@yxy conf]# vi /etc/profile

修改配置文件并保存：

# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

2.4启动zookeeper

执行zkServer.sh脚本进行启动，命令是：

        zkServer.sh   start

如图：

2.5查看zookeeper的状态

    执行命令查看zookeeper状态：

        zkServer.sh    status

如图：

standalone 是单机模式。
