安装zookeeper前需要你安装jdk；你可以查看：
Linux系统下安装JDK,Tomcat和Mysql：
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。
