Ubuntu部署zookeeper

2.1 创建文件夹

/home/xdq/xinPrj/zookeeper

mkdir zookeeper cd zookeeper 

2.2 解压文件

• 解压到当前文件夹

tar -zxvf zookeeper-3.5.1-alpha.tar.gz -C . 

• 文件目录

├── zookeeper │ ├── zookeeper-3.5.1-alpha │ │ ├── bin │ │ ├── build.xml │ │ ├── CHANGES.txt │ │ ├── conf │ │ ├── contrib │ │ ├── dist-maven │ │ ├── docs │ │ ├── ivysettings.xml │ │ ├── ivy.xml │ │ ├── lib │ │ ├── LICENSE.txt │ │ ├── NOTICE.txt │ │ ├── README_packaging.txt │ │ ├── README.txt │ │ ├── recipes │ │ ├── src │ │ ├── zookeeper-3.5.1-alpha.jar │ │ ├── zookeeper-3.5.1-alpha.jar.asc │ │ ├── zookeeper-3.5.1-alpha.jar.md5 │ │ └── zookeeper-3.5.1-alpha.jar.sha1 │ └── zookeeper-3.5.1-alpha.tar.gz 

2.3 配置文件

• 创建文件conf/zoo.cfg
  内容拷贝conf/zoo_sample.cfg即可,修改dataDir.

# ZooKeeper时间单位,用于心跳和最小任务超时为tickTime的两倍 tickTime=2000 # 存储数据 dataDir=/home/xdq/xinPrj/zookeeper/datas # 客户端连接监听端口 clientPort=2181

• cmd

bin/zkServer.sh stop 

• Result

ZooKeeper JMX enabled by default Using config: /home/xdq/xinPrj/zookeeper/zookeeper-3.5.1-alpha/bin/../conf/zoo.cfg Stopping zookeeper ... STOPPED 

3.1 配置hosts

sudo vim /etc/hosts 

127.0.0.1 localhost 

3.2 zoo.cfg文件

假设伪集群数目:3个,则需要配置三份zoo.cfg,路径:/path/zookeeper/conf/zoo.cfg分别如下

• zoo1.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk1/data dataLogDir=/tmp/zk1/log clientPort=2181 server.1=localhost:2877:3877 server.2=localhost:2888:3888 server.3=localhost:2899:3899 

• zoo2.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk2/data dataLogDir=/tmp/zk2/log clientPort=2182 server.1=localhost:2877:3877 server.2=localhost:2888:3888 server.3=localhost:2899:3899 

• zoo3.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk3/data dataLogDir=/tmp/zk3/log clientPort=2183 server.1=localhost:2877:3877 server.2=localhost:2888:3888 server.3=localhost:2899:3899 

3.3 配置zookeeper服务id

在dataDir所在的路径下建立myid文件,两种方式:

• echo写入

echo 1>/tmp/zk1/data/myid echo 1>/tmp/zk2/data/myid echo 1>/tmp/zk3/data/myid 

• vim 写入

sudo vim /tmp/zk1/data/myid sudo vim /tmp/zk2/data/myid sudo vim /tmp/zk3/data/myid

4.1 第一台服务

• zoo.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk3/data dataLogDir=/tmp/zk3/log clientPort=2181 server.1=kafka1:2888:3888 server.2=kafka2:2888:3888 server.3=kafka3:2888:3888 

4.2 第二台服务

• zoo.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk3/data dataLogDir=/tmp/zk3/log clientPort=2181 server.1=kafka1:2888:3888 server.2=kafka2:2888:3888 server.3=kafka3:2888:3888 

4.3 第三台服务

• zoo.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zk3/data dataLogDir=/tmp/zk3/log clientPort=2181 server.1=kafka1:2888:3888 server.2=kafka2:2888:3888 server.3=kafka3:2888:3888 

4.4 建立id

在dataDir路径下建立myid文件，并写入server.x对应的x，如1,2,3。

• echo写入

echo 1>/tmp/zk1/data/myid echo 1>/tmp/zk2/data/myid echo 1>/tmp/zk3/data/myid 

• vim 写入

sudo vim /tmp/zk1/data/myid sudo vim /tmp/zk2/data/myid sudo vim /tmp/zk3/data/myid 

4.5 Usage

bin/zkServer.sh start 

bin/zkServer.sh status 

bin/zkServer.sh restart 

bin/zkServer.sh stop
