+##  环境版本
+* 操作系统：CentOS release 6.6 (Final)
+* java版本: jdk1.8
+* zookeeper版本: zookeeper-3.4.11
+
+##  一、 安装jdk
+```
+此处省略
+```
+##  二、 安装zookeeper
+### 2.1 下载源码包，并解压
+官网下载地址：`http://www.apache.org/dyn/closer.cgi/zookeeper`
+```
+wget http://mirror.olnevhost.net/pub/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz
+tar zxvf zookeeper-3.4.11.tar.gz  
+mv zookeeper-3.4.11 /usr/local/zookeeper
+```
+### 2.2 修改环境变量
+编辑 /etc/profile 文件, 在文件末尾添加以下环境变量配置:
+```
+# ZooKeeper Env
+export ZOOKEEPER_HOME=/usr/local/zookeeper
+export PATH=$PATH:$ZOOKEEPER_HOME/bin
+```
+运行以下命令使环境变量生效:
+` source /etc/profile `
+### 2.3 重命名配置文件
+初次使用 ZooKeeper 时,需要将$ZOOKEEPER_HOME/conf 目录下的 zoo_sample.cfg 重命名为 zoo.cfg, zoo.cfg 
+```
+mv  $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
+```
+### 2.4 单机模式--修改配置文件
+创建目录`/usr/local/zookeeper/data` 和`/usr/local/zookeeper/logs`
+修改配置文件
+```
+tickTime=2000
+initLimit=10
+syncLimit=5
+dataDir=/usr/local/zookeeper/data
+dataLogDir=/usr/local/zookeeper/logs
+clientPort=2181
+```
+如果是多节点,配置文件中尾部增加
+```
+server.1=192.168.1.110:2888:3888
+server.2=192.168.1.111:2888:3888
+server.3=192.168.1.112:2888:3888
+```
+同时,增加
+```
+#master
+echo "1">/usr/local/zookeeper/data/myid
+
+#slave1
+echo "2">/usr/local/zookeeper/data/myid
+
+#slave2
+echo "3">/usr/local/zookeeper/data/myid
+
+```
+### 2.5 启动 ZooKeeper 服务
+```
+# cd /usr/local/zookeeper/zookeeper-3.4.11/bin
+# ./zkServer.sh  start
+ZooKeeper JMX enabled by default
+Using config: /usr/local/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg
+Starting zookeeper ... STARTED
+
+zkServer.sh  status
+ZooKeeper JMX enabled by default
+Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
+Mode: follower
+```
+### 2.6 验证zooKeeper服务
+服务启动完成后，可以使用 telnet 和 stat 命令验证服务器启动是否正常:
+```
+# telnet 127.0.0.1 2181
+Trying 127.0.0.1...
+Connected to 127.0.0.1.
+Escape character is '^]'.
+stat
+Zookeeper version: 3.4.11-37e277162d567b55a07d1755f0b31c32e93c01a0, built on 11/01/2017 18:06 GMT
+Clients:
+/127.0.0.1:48430[0](queued=0,recved=1,sent=0)
+
+Latency min/avg/max: 0/0/0
+Received: 1
+Sent: 0
+Connections: 1
+Outstanding: 0
+Zxid: 0x0
+Mode: standalone
+Node count: 4
+Connection closed by foreign host.
+```
+### 2.7 停止 ZooKeeper 服务
+想要停止 ZooKeeper 服务, 可以使用如下命令:
+```
+# cd /usr/local/zookeeper/zookeeper-3.4.11/bin
+# ./zkServer.sh  stop
+ZooKeeper JMX enabled by default
+Using config: /usr/local/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg
+Stopping zookeeper ... STOPPED
+
+```
+## 三、zk ui安装 (选装，页面查看zk的数据)
+### 拉取代码
+```
+#git clone https://github.com/DeemOpen/zkui.git
+```
+### 源码编译需要安装 maven
+```
+# wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
+#cd zkui/
+#yum install -y maven
+#mvn clean install
+```
+### 修改配置文件默认值
+```
+#vim config.cfg
+    serverPort=9090     #指定端口
+    zkServer=192.168.1.110:2181
+    sessionTimeout=300000
+```
+### 启动程序至后台
+
+2.0-SNAPSHOT 会随软件的更新版本不同而不同，执行时请查看target 目录中真正生成的版本
+```
+ nohup java -jar target/zkui-2.0-SNAPSHOT-jar-with-dependencies.jar & 
+```
