kafka集群安装和kafka-manager

1、软件环境

（3台服务器-测试）
* mykafka1
* mykafka2
* mykafka3

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@localhost ~]# lscpu
[root@localhost ~]# free -m
[root@localhost ~]# df -h
[root@localhost opt]# hostnamectl set-hostname mykafka1
[root@localhost opt]# yum list java*
Installed Packages
java-1.8.0-openjdk.x86_64 1:1.8.0.65-3.b17.el7 @anaconda
java-1.8.0-openjdk-headless.x86_64 1:1.8.0.65-3.b17.el7
[root@localhost opt]# yum list installed|grep java*
java-1.8.0-openjdk.x86_64 1:1.8.0.65-3.b17.el7 @anaconda
java-1.8.0-openjdk-headless.x86_64 1:1.8.0.65-3.b17.el7 @anaconda
--如果没有安装java，则需要安装java
--yum -y install java-1.8.0-openjdk*
--centos 7 自带

2 安装zookeeper

下载安装包，本地安装包路径
[root@mykafka1 opt]# ll
total 88132
-rw-r--r--. 1 root root 55201623 Nov 29 10:34 kafka_2.12-2.1.0.tgz
-rw-r--r--. 1 root root 35042811 Nov 29 10:35 zookeeper-3.4.10.tar.gz
[root@mykafka1 opt]# scp kafka_2.12-2.1.0.tgz zookeeper-3.4.10.tar.gz root@*:/opt/.
[root@mykafka1 opt]# scp kafka_2.12-2.1.0.tgz zookeeper-3.4.10.tar.gz root@*:/opt/.
--没有就下载
--wget --no-check-certificate https://www.apache.org/dist/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
[root@mykafka1 opt]# tar zxvf zookeeper-3.4.10.tar.gz -C /usr/local/
[root@mykafka1 local]# cd /usr/local/zookeeper-3.4.10/
[root@mykafka1 zookeeper-3.4.10]# mkdir {logs,data}
[root@mykafka1 zookeeper-3.4.10]# cd conf/
[root@mykafka1 conf]# cp zoo_sample.cfg zoo.cfg
[root@mykafka1 conf]# cat /usr/local/zookeeper-3.4.10/conf/zoo.cfg |grep -Ev "^#|^$"
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/zookeeper-3.4.10/data/
dataLogDir=/usr/local/zookeeper-3.4.10/log/
clientPort=2181
server.1=*:2888:3888
server.2=*:2888:3888
server.3=*:2888:3888

#server.1 这个1是服务器的标识也可以是其他的数字， 表示这个是第几号服务器，用来标识服务器，这个标识要写到快照目录下面myid文件里
#*为集群里的IP地址，第一个端口是master和slave之间的通信端口，默认是2888，第二个端口是leader选举的端口，集群刚启动的时候选举或者leader挂掉之后进行新的选举的端口默认是3888

创建myid文件
#server1
[root@mykafka1 conf]# echo "1" > /usr/local/zookeeper-3.4.10/data/myid
#server2
[root@mykafka2 conf]# echo "2" > /usr/local/zookeeper-3.4.10/data/myid
#server3
[root@mykafka3 conf]# echo "3" > /usr/local/zookeeper-3.4.10/data/myid

1、myid文件和server.myid 在快照目录下存放的标识本台服务器的文件，他是整个zk集群用来发现彼此的一个重要标识。
2、zoo.cfg 文件是zookeeper配置文件 在conf目录里。
3、log4j.properties文件是zk的日志输出文件 在conf目录里用java写的程序基本上有个共同点日志都用log4j，来进行管理。

[root@mykafka1 conf]# head -n 30 log4j.properties
# Define some default values that can be overridden by system properties
zookeeper.root.logger=INFO, CONSOLE
zookeeper.console.threshold=INFO
zookeeper.log.dir=.
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=DEBUG
zookeeper.tracelog.dir=.
zookeeper.tracelog.file=zookeeper_trace.log

zkServer.sh 主的管理程序文件
zkEnv.sh 是主要配置，zookeeper集群启动时配置环境变量的文件

启动zookeeper 启动顺序zookeeper-1>zookeeper-2>zookeeper-3
--/usr/local/zookeeper-3.4.10/bin/zkServer.sh start /usr/local/zookeeper-3.4.10/conf/zoo.cfg

[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh start /usr/local/zookeeper-3.4.10/conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/conf/zoo.cfg
Starting zookeeper ... STARTED
[root@mykafka2 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh start /usr/local/zookeeper-3.4.10/conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/conf/zoo.cfg
Starting zookeeper ... STARTED
[root@mykafka3 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh start /usr/local/zookeeper-3.4.10/conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/conf/zoo.cfg
Starting zookeeper ... STARTED

[root@mykafka1 config]# ps -ef|grep zookeeper

查看leader
--/usr/local/zookeeper-3.4.10/bin/zkServer.sh status /usr/local/zookeeper-3.4.10/conf/zoo.cfg
--[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status
[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status /usr/local/zookeeper-3.4.10/conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/conf/zoo.cfg
Error contacting service. It is probably not running.
发现错误，检查配置文件，应该没问题，可能是防火墙（3台一样的处理）
[root@mykafka1 conf]# systemctl status firewalld.service
[root@mykafka1 conf]# systemctl stop firewalld.service
[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh restart
[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: follower

3台都重启后，发现1位leader,另外两台是follower
[root@mykafka1 conf]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: leader
[root@mykafka2 config]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: follower
[root@mykafka3 config]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: follower

3 Kafka集群搭建

[root@mykafka1 opt]# tar zxvf kafka_2.12-2.1.0.tgz -C /usr/local/
[root@mykafka1 opt]# cd /usr/local/kafka_2.12-2.1.0/config/
broker.id=0
listeners=PLAINTEXT://*:9092
log.dirs=/tmp/kafka-logs
zookeeper.connect=*:2181,*:2181,1*:2181

---mykafka2
broker.id=1
listeners=PLAINTEXT://*:9092
log.dirs=/tmp/kafka-logs
zookeeper.connect=*:2181,*:2181,*:2181

--mykafka3
broker.id=2
listeners=PLAINTEXT://*:9092
log.dirs=/tmp/kafka-logs
zookeeper.connect=*:2181,*:2181,*:2181

[root@mykafka1 config]# vim /etc/profile
export KAFKA_HOME=/usr/local/kafka_2.12-2.1.0
PATH=${KAFKA_HOME}/bin:$PATH
export PATH
[root@mykafka1 config]# source /etc/profile

启动kafka
[root@mykafka1 config]# /usr/local/kafka_2.12-2.1.0/bin/kafka-server-start.sh -daemon /usr/local/kafka_2.12-2.1.0/config/server.properties
[root@mykafka1 config]# ps -ef|grep kafka

创建topic–test
--/usr/local/kafka_2.12-2.1.0/bin/kafka-topics.sh --create --zookeeper *:2181 --replication-factor 3 --partitions 3 --topic hongquan
#解释
--replication-factor 3 #复制3份
--partitions 3 #创建3个分区
--topic #主题为hongquan

#创建一个broker，发布者

/usr/local/kafka_2.12-2.1.0/bin/kafka-console-producer.sh --broker-list *:9092 --topic hongquan

# 创建一个订阅者

/usr/local/kafka_2.12-2.1.0/bin/kafka-console-consumer.sh --zookeeper *:2181 --from-beginning --topic hongquan

/usr/local/kafka_2.12-2.1.0/bin/kafka-topics.sh --describe --zookeeper *:2181 --topic test
查看topic
/usr/local/kafka_2.12-2.1.0/bin/kafka-topics.sh --list --zookeeper *:2181,*:2181,*:2181
查看topic状态
/usr/local/kafka_2.12-2.1.0/bin/kafka-topics.sh --describe --zookeeper *:2181,*:2181,*:2181 --topic hongquan

4 kafka-manager安装

官网下载，git clone https://github.com/yahoo/kafka-manager.git，这里下载的需要进行源码编译，有点麻烦，这里采用编译好的包

kafka-manager-1.3.3.7.zip 此安装包可以在baidu网盘上进行下载

链接: https://pan.baidu.com/s/15dneVAnMx76qaKV2SuSKDw 提取码: knie

[root@mykafka1 opt]# unzip kafka-manager-1.3.3.7.zip -d /data/
[root@mykafka1 opt]# cd /data/kafka-manager-1.3.3.7/conf/
[root@mykafka1 conf]# cp application.conf application.conf.bk
[root@mykafka1 conf]# vim application.conf
kafka-manager.zkhosts="*:2181,*:2181,*:2181"

kafka-manager 默认的端口是9000，可通过 -Dhttp.port，指定端口; -Dconfig.file=conf/application.conf指定配置文件:
[root@mykafka1 kafka-manager-1.3.3.7]# nohup bin/kafka-manager -Dconfig.file=conf/application.conf -Dhttp.port=8080 &

[root@mykafka1 kafka-manager-1.3.3.7]# tail -f -n 100 nohup.out
