复制三台虚拟机
-
修改主机名及hosts
vim /etc/hostname- 将三台主机的主机名分别修改为kafka01, kafka02, kafka03
vim /etc/hosts修改为:
127.0.0.1 localhost 192.168.180.200 kafka01 192.168.180.201 kafka02 192.168.180.202 kafka03 -
关闭防火墙
# ps: 这里就不搞iptables防火墙了, 直接关, 不然开得一个个开放端口, 比较烦
service firewalld stop

JDK安装
-
将jdk的tar包上传，然后tar -zxvf 该包 -C 想要解压到的目录
-
我这边是解压到了/opt/ronnie/目录, 并且 mv jdk1.8XXXX jdk1.8 将它改名为了jdk1.8
[root@kafka02 ronnie]# ll
总用量 0
drwxr-xr-x. 7 10 143 245 12月 16 2018 jdk1.8
drwxrwxrwx. 8 root root 120 10月 4 13:00 kafka
drwxr-xr-x. 8 root root 158 10月 2 20:20 zookeeper
-
修改系统配置文件
vim /etc/profile # 添加jdk路径 export JAVA_HOME=/opt/ronnie/jdk1.8 export PATH=$JAVA_HOME/bin:$PATH检查配置是否成功:
[root@kafka02 .ssh]# java -version java version "1.8.0_202" Java(TM) SE Runtime Environment (build 1.8.0_202-b08) Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode) [root@kafka02 .ssh]# javac -version javac 1.8.0_202将配置好的jdk目录传送给其他几台机器:
scp -r /opt/ronnie/jdk1.8 root@192.168.180.xxx:/opt/ronnie
Zookeeper安装
-
上传Zookeeper的tar包, 我这里用的是3.5.5
-
tar -zxvf 该包 -C 你想要解压到的目录
我这里一样解压到了/opt/ronnie/下, 并 mv zookeeperXXXXX zookeeper 将其重命名为zookeeper
- 创建data目录:
mkdir -p /opt/ronnie/zookeeper/data- 在data目录下创建日志目录:
mkdir -p /opt/ronnie/zookeeper/data/log- 在data目录下创建zk目录:
mkdir -p /opt/ronnie/zookeeper/data/zk-
cd zk/, 创建myid, 三台虚拟机kafka01, kafka02, kafka03 分别对应myid 1,2,3
-
进入zookeeper的配置文件目录, 创建并修改zoo.cfg
cd /opt/ronnie/zookeeper/conf # 拷贝一份zoo_sample.cfg 为 zoo.cfg cp zoo_sample.cfg zoo.cfg # 修改zoo.cfg文件 vim zoo.cfgzoo.cfg:
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/opt/ronnie/zookeeper/data/zk dataLogDir=/opt/ronnie/zookeeper/data/log # the port at which the clients will connect clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1 server.1=kafka01:2888:3888 server.2=kafka02:2888:3888 server.3=kafka03:2888:3888 -
将zookeeper添加至环境目录
vim /etc/profile # 添加Zookeeper配置 export ZOOKEEPER_HOME=/opt/ronnie/zookeeper export PATH=$ZOOKEEPER_HOME/bin:$PATH -
将配置好的zookeeper目录传送给其他几台虚拟机
scp -r /opt/ronnie/zookeeper root@192.168.180.xxx:/opt/ronnie-
启动Zookeeper: zkServer.sh start
-
检查Zookeeper启动状态: zkServer.sh status
成功启动案例:
[root@kafka02 conf]# zkServer.sh status ZooKeeper JMX enabled by default Using config: /opt/ronnie/zookeeper/bin/../conf/zoo.cfg Client port found: 2181. Client address: localhost. Mode: leader 如果报了: JMX enabled by default
Using config: /hadoop/zookeeper/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.可能是配置文件的问题, 也可能是防火墙的问题, 可以cd logs 去查看下日志中的报错来定位问题
Kafka安装
- 上传kafka的tar包, 并tar -zxvf -C 你想要解压的目录,
我这用的是2.12-2.3.0版本的kafka
-
修改配置文件

More partitions allow greater # parallelism for consumption, but this will also result in more files across # the brokers. num.partitions=1 # The number of threads per data directory to be used for log recovery at startup and flushing at shutdown. # This value is recommended to be increased for installations with data dirs located in RAID array. num.recovery.threads.per.data.dir=1 ############################# Internal Topic Settings ############################# offsets.topic.replication.factor=1 transaction.state.log.replication.factor=1 transaction.state.log.min.isr=1 ############################# Log Flush Policy ############################# # Messages are immediately written to the filesystem but by default we only fsync() to sync # the OS cache lazily. The following configurations control the flush of data to disk. # There are a few important trade-offs here: # 1. Durability: Unflushed data may be lost if you are not using replication. # The settings below allow one to configure the flush policy to flush data after a period of time or # every N messages (or both). This can be done globally and overridden on a per-topic basis. #log.flush.interval.ms=1000 # be set to delete segments after a period of time, or after a given size has accumulated. # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens # from the end of the log. # The minimum age of a log file to be eligible for deletion due to age log.retention.hours=168 # A size-based retention policy for logs. Segments are pruned from the log unless the remaining # segments drop below log.retention.bytes. Functions independently of log.retention.hours. #log.retention.bytes=1073741824 # The maximum size of a log segment file.

Kafka-eagle安装
- 下载
https://codeload.github.com/smartloli/kafka-eagle-bin/tar.gz/v1.3.9
- 上传tar包并 tar -zxvf -C /opt/ronnie/kafka， 然后 mv kafka-eagle-xxxxx kafka-eagle 将解压后的文件重命名为kafka-eagle
- 然后你会发现里面还有一个tar包..... tar -zxvf 该包 解压到当前目录并删除tar包
- 配置环境变量
