使用 Clustershell 搭建 Kafka 和 Zookeeper 集群

1、安装环境

虚拟机环境，共有三台虚拟主机：
Router1 192.168.3.116
Router2 192.168.3.115
Router3 192.168.3.121

2、CMD 工具

SecureCRT 7.2.3
具有 Tile 功能，可以将多个 session 窗口并列显示。
设置在菜单 windows ->Tile Vertically，并且有显示 command windows 功能. 设置在菜单 View -> Command windows. 在 command windows 中可以右键设置 send commands to all sessions 菜单，就可以在 commandwindows 中输入命令后向所有 sessions 发送输入的命令。

3、搭建 zookeeper 集群

3.1 设置多台机器免密码

在 command windows 中输入命令

-bash-4.1# ls /root/.ssh
known_hosts
// 删除原有文件
-bash-4.1# rm -rf /root/.ssh/*
-bash-4.1# ls /root/.ssh
// 生成密钥文件
-bash-4.1# ssh-keygen -t rsa
Generating public/private rsa keypair.
Enter file in which to save the key(/root/.ssh/id_rsa):
Enter passphrase (empty for nopassphrase):
Enter same passphrase again: 
Your identification has been savedin /root/.ssh/id_rsa.
Your public key has been saved in/root/.ssh/id_rsa.pub.
The key fingerprint is:
82:1b:17:2f:30:7c:62:db:7c:34:4a:0d:d5:20:46:dcroot@router1
The key's randomart image is:

使用 Clustershell 搭建 Kafka 和 Zookeeper 集群

3.2 设置 zookeeper 集群

在主机 1 中安装 clustershell 工具

访问网站：http://clustershell.readthedocs.io/en/latest/install.html#red-hat-enterprise-linux-and-CentOS
$ yum --enablerepo=extrasinstall epel-release
$ yum installclustershell vim-clustershell

配置 clustershell，建立 group

** 在 /etc/clustersheel 目录下建立 groups 文件 **
Cd /etc/clustersheel
Vi groups
kafka: router[1-3]
注：router 是主机名的前缀
在主机 1 中拷贝和解压安装包
-bash-4.1# tar -zxvfzookeeper-3.4.9.tar.gz
-bash-4.1# tar -zxvfkafka_2.11-0.8.2.1.tgz

通过 clustershell 统一拷贝 zookeeper 和 kafaka 的安装包
-bash-4.1# clush -g kafka -c/opt/kafka/
验证是否拷贝成功
Ls /opt/kafka

使用 Clustershell 搭建 Kafka 和 Zookeeper 集群

修改 zookeeper 的配置文件

-bash-4.1# cp zoo_sample.cfgzoo.cfg
修改每台主机的 zoo.cfg中的 zoo.cfg文件
增加集群信息
server.1=router1:2888:3888
server.2=router2:2888:3888
server.3=router3:2888:3888
注：2888端口是作为 leader 与 follow 间通讯的，3888端口是作为 leader 选举的。同步 zookeeper 的配置文件
-bash-4.1# clush -g kafka -c/opt/kafka/zookeeper-3.4.9/conf/zoo.cfg

创建 zookeeper 数据目录
-bash-4.1# clush -g kafka mkdir/tmp/zookeeper


在每台机器中建立 myid 文件
主机 1 执行
-bash-4.1# echo "1" >/tmp/zookeeper/myid

主机 2 执行
-bash-4.1# echo "2" >/tmp/zookeeper/myid

主机 3 执行
-bash-4.1# echo "3" >/tmp/zookeeper/myid

主机 1 上验证
-bash-4.1# clush -g kafka cat/tmp/zookeeper/myid
router2: 2
router3: 3
router1: 1

启动 zookeeper 集群，在主机 1 上执行

-bash-4.1# clush -g kafka"/opt/kafka/zookeeper-3.4.9/bin/zkServer.sh start/opt/kafka/zookeeper-3.4.9/conf/zoo.cfg"
router3: ZooKeeper JMX enabled by default
router3: Using config: /opt/kafka/zookeeper-3.4.9/conf/zoo.cfg
router2: ZooKeeper JMX enabled by default
router2: Using config: /opt/kafka/zookeeper-3.4.9/conf/zoo.cfg
router1: ZooKeeper JMX enabled by default
router1: Using config: /opt/kafka/zookeeper-3.4.9/conf/zoo.cfg
router3: Starting zookeeper ... STARTED
router2: Starting zookeeper ... STARTED
router1: Starting zookeeper ... STARTED

# 连接第一个主机的 zookeeper，建立测试键值进行测试
-bash-4.1# bin/zkCli.sh -server router1
Connecting to router1
[zk: router1(CONNECTED) 8] create/test_install hello
Created /test_install
[zk: router1(CONNECTED) 9] ls/                     
[test_install, zookeeper]

# 连接第二个主机的 zookeeper，查看测试键值是否存在
-bash-4.1# bin/zkCli.sh -serverrouter2
Connecting to router2
ls /
[test_install, zookeeper]

4、建立 kafaka 集群
修改第一台主机中 kafka 目录的 config 子目录中的 server.properties 配置文件

zookeeper.connect=router1:2181,router2:2181,router3:2181/kafka

将 server.properties 配置文件分发到其他两台主机中

-bash-4.1# clush-g kafka -c /opt/kafka/kafka_2.11-0.8.2.1/config/server.properties

分别修改三台主机的 server.properties 配置文件，配置不同的 broker.id

第一台主机的 broker.id设置为 broker.id=1
第二台主机的 broker.id设置为 broker.id=2
第三台主机的 broker.id设置为 broker.id=3

启动 kafka 集群

-bash-4.1# clush-g kafka /opt/kafka/kafka_2.11-0.8.2.1/bin/kafka-server-start.sh -daemon/opt/kafka/kafka_2.11-0.8.2.1/config/server.properties

验证 9092 端口

-bash-4.1# clush-g kafka lsof -i:9092

建立测试是 topic

-bash-4.1#bin/kafka-topics.sh -create --topic test1 --zookeeper router1:2181/kakfa--partitions 3 --replication-factor 2
Created topic"topic1".

-bash-4.1#bin/kafka-topics.sh -describe --topic test1 --zookeeper router1:2181/kafka
Topic:topic1   PartitionCount:3       ReplicationFactor:2    Configs:
        Topic: topic1  Partition: 0   Leader: 1      Replicas: 1,2  Isr: 1,2
        Topic: topic1  Partition: 1   Leader: 2      Replicas: 2,3  Isr: 2,3
        Topic: topic1  Partition: 2   Leader: 3      Replicas: 3,1  Isr: 3,1
