复制三台虚拟机

Centos7.4 kafka集群安装与kafka

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

免密登录

ssh-keygen
# 然后enter, enter, enter 直到生成RSA, 默认会在当前用户的家目录下生成.ssh

[root@kafka02 ~]# ls -ah
.                .bash_history  .bashrc  .cshrc                .pki     .viminfo      .xauthEJoei0
..               .bash_logout   .cache   .dbus                 .ssh     .xauthBayboq
anaconda-ks.cfg  .bash_profile  .config  initial-setup-ks.cfg  .tcshrc  .xauthcwYAMX

.ssh隐藏目录中有id_rsa(私钥) 和 id_rsa.pub(公钥)

cd ~/.ssh 创建authorized_keys，将三台虚拟机的公钥都存入其中:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCZJgAqbq+/peLIdV5ZpDSS3+8nYJSg/2ZON8rj9WmXlefGLgoegRFExCN4LPEN72/QEl/ZOBxtc00Tev+pSM30veOkxJTc+XXGu5LlFp3l5bbB0nIZG5hYKstT7FYPDfNqZkJrNp+6l0Yl/Eihv9R4LPT5K2A4TbxtFi7s9c0n2fUp5XOLjQWU9qj1x7bajV0nLjV3gOeejqNKVywr2xQqOJX7DQ/e1jlKekvUGHpa/fWVyTc/rK7dCvyddAqqrO5P+7Tu9CqLvcvV1hFtgVechCJ0VCw3tId3qczJzEj51KJb1hErzCFz+7azOMkLhw0/NkX36PjgPX6F59AOsPhX root@kafka01

每台虚拟机的authorized_keys文件一致

免密登录测试:

[root@kafka03 bin]# ssh root@192.168.180.201
Last login: Fri Oct  4 13:06:53 2019
[root@kafka02 ~]#

ps：第一次会提示是否将该秘钥保存, 保存后.ssh文件目录下会生成一个known_hosts，里面存有已知的主机sha(Security HashCode Algorithum)信息:

比如我的:

192.168.180.200 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBOozduEWhzGQL5NzN1ZTpRUqfXQBNCDEq4YHeElcxuk17xsGr6job8H5lxFkf+0FwcD2ZFkbZeUJS/UnR0EtdzA=

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.cfg

zoo.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 Centos7.4 kafka集群安装与kafka

修改配置文件

vim /opt/ronnie/kafka/config/server.properties

# see kafka.server.KafkaConfig for additional details and defaults

############################# Server Basics #############################

# The id of the broker. This must be set to a unique integer for each broker.
# brokerId 需要是唯一的, 这里我就把每台的brokerId分别设置成200,201 和 202 了
broker.id=200 

# port 端口
port=9092

# hostname 主机名, 分别修改为各自对应的
host.name=kafka01

############################# Socket Server Settings #############################

# The address the socket server listens on. It will get the value returned from 
# java.net.InetAddress.getCanonicalHostName() if not configured.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
# 监听者也需要将主机名设置为各自对应的
listeners=PLAINTEXT://kafka01:9092
#advertised.listeners=PLAINTEXT://your.host.name:9092

#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

num.network.threads=3

socket.send.buffer.bytes=102400

# The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer.bytes=102400

# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600


############################# Log Basics #############################

# A comma separated list of directories under which to store log files
log.dirs=/tmp/kafka-logs

# The default number of log partitions per topic. 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. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000

############################# Zookeeper #############################

# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
# zookeeper的连接
zookeeper.connect=kafka01:2181,kafka02:2181,kafka03:2181

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=6000


############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms=0

将配置好的kafka目录发送给其他虚拟机

scp -r /opt/ronnie/kafka root@192.168.180.xxx:/opt/ronnie
在三台虚拟机上启动kafka

cd /opt/ronnie/kafka bin/kafka-server-start.sh config/server.properties&
