--------------------

# 1 准备工作 #

1、安装JDK  
2、将Zookeeper上传到服务器  
3、解压Zookeeper，并创建data目录，将conf下的zoo\_sample.cfg文件改名为zoo.cfg

### 安装目录
    mkdir -p /usr/local/server && cd /usr/local/server
    ### 下载
    wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz
    ### 解压
    tar -zxvf zookeeper-3.4.11.tar.gz

### 文件改名为zoo.cfg
    cd /usr/local/server/zookeeper-3.4.11/conf && mv zoo_sample.cfg zoo.cfg
    ### 创建data目录
    cd /usr/local/server/zookeeper-3.4.11 && mkdir data log

4、建立 /user/local/server/zookeeper-cluster/zookeeper-x，将解压后的Zookeeper复制到以下三个目录

mkdir -p /usr/local/server/zookeeper-cluster/zookeeper-1
    mkdir -p /usr/local/server/zookeeper-cluster/zookeeper-2
    mkdir -p /usr/local/server/zookeeper-cluster/zookeeper-3

cp -rf /usr/local/server/zookeeper-3.4.11/* /usr/local/server/zookeeper-cluster/zookeeper-1
    cp -rf /usr/local/server/zookeeper-3.4.11/* /usr/local/server/zookeeper-cluster/zookeeper-2
    cp -rf /usr/local/server/zookeeper-3.4.11/* /usr/local/server/zookeeper-cluster/zookeeper-3

5、配置每一个 Zookeeper 的 dataDir（zoo.cfg） clientPort 分别为 2181 2182 2183

**修改**/usr/local/server/zookeeper-cluster/zookeeper-1/conf/zoo.cfg

### 修改zookeeper-1的配置文件
    vi /usr/local/server/zookeeper-cluster/zookeeper-1/conf/zoo.cfg

### 修改
    clientPort=2181
    dataDir=/usr/local/server/zookeeper-cluster/zookeeper-1/data
    ### 添加
    dataLogDir=/usr/local/server/zookeeper-cluster/zookeeper-1/log

**修改**/usr/local/server/zookeeper-cluster/zookeeper-2/conf/zoo.cfg

### 修改zookeeper-2的配置文件
    vi /usr/local/server/zookeeper-cluster/zookeeper-2/conf/zoo.cfg

clientPort=2182
    dataDir=/usr/local/server/zookeeper-cluster/zookeeper-2/data
    dataLogDir=/usr/local/server/zookeeper-cluster/zookeeper-2/log

** 修改**/usr/local/server/zookeeper-cluster/zookeeper-3/conf/zoo.cfg

### 修改zookeeper-3的配置文件
    vi /usr/local/server/zookeeper-cluster/zookeeper-3/conf/zoo.cfg

clientPort=2183
    dataDir=/usr/local/server/zookeeper-cluster/zookeeper-3/data
    dataLogDir=/usr/local/server/zookeeper-cluster/zookeeper-3/log

--------------------

# 2 配置集群 #

1、在每个 zookeeper 的 data 目录下创建一个 myid 文件，内容分别是 1、2、3 。这个文件就是记录每个服务器的 ID

echo 1 > /usr/local/server/zookeeper-cluster/zookeeper-1/data/myid
    echo 2 > /usr/local/server/zookeeper-cluster/zookeeper-2/data/myid
    echo 3 > /usr/local/server/zookeeper-cluster/zookeeper-3/data/myid

2、在每一个 zookeeper 的 zoo.cfg 配置文件中末尾**追加**客户端访问端口（clientPort）和集群服务器 IP 列表。

vi /usr/local/server/zookeeper-cluster/zookeeper-1/conf/zoo.cfg

vi /usr/local/server/zookeeper-cluster/zookeeper-2/conf/zoo.cfg

vi /usr/local/server/zookeeper-cluster/zookeeper-3/conf/zoo.cfg

集群服务器 IP 列表如下

server.1=121.36.33.154:2881:3881
    server.2=121.36.33.154:2882:3882
    server.3=121.36.33.154:2883:3883

解释：server.服务器 ID=服务器 IP 地址**:**服务器之间通信端口**:**服务器之间投票选举端口

--------------------

# 3 启动集群 #

启动集群就是分别启动每个实例。

/usr/local/server/zookeeper-cluster/zookeeper-1/bin/zkServer.sh start
    /usr/local/server/zookeeper-cluster/zookeeper-2/bin/zkServer.sh start
    /usr/local/server/zookeeper-cluster/zookeeper-3/bin/zkServer.sh start
