Kafka 内核部分需要安装jdk, zookeeper.
安装JDK就不需要讲解了,安装完配置下JAVA_HOME,和Path,将java安装目录和运行文件目录配置下就ok拉。
安装地址: 下载
安装地址:下载
安装完zookeeper 需要配置如下信息:
下载后,解压放在目录D:\bigdata(本文所用的目录)下,关于zookeeper以及kafka的目录,路径中最好不要出现空格,比如D:\Program Files,尽量别用,运行脚本时会有问题。
1.进入zookeeper的相关设置所在的文件目录,例如本文的:D:\bigdata\zookeeper-3.4.10\conf
2.将"zoo_sample.cfg"重命名为"zoo.cfg"
3.打开zoo.cfg(至于使用什么编辑器,根据自己喜好选即可),找到并编辑:
dataDir=/tmp/zookeeper to D:/bigdata/zookeeper-3.4.10/data或 D:\bigdata\zookeeper-3.4.10\data(路径仅为示例,具体可根据需要配置)
这里注意,路径要么是"/"分割,要么是转义字符"\",这样会生成正确的路径(层级,子目录)。
4.与配置jre类似,在系统环境变量中添加:
a.系统变量中添加ZOOKEEPER_HOME=D:\bigdata\zookeeper-3.4.10
b.编辑系统变量中的path变量,增加%ZOOKEEPER_HOME%\bin
5在zoo.cfg文件中修改默认的Zookeeper端口(默认端口2181)
这是本文最终的zoo.cfg文件的内容:
# 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=D:/bigdata/zookeeper-3.4.10/data
#dataDir=D:\\bigdata\\zookeeper-3.4.10\\data
# 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进入kafka配置文件所在目录,D:\bigdata\kafka_2.11-0.9.0.1\config
②编辑文件"server.properties",找到并编辑:
log.dirs=/tmp/kafka-logs to log.dirs=D:/bigdata/kafka_2.11-0.9.0.1/kafka-logs 或者 D:\bigdata\kafka_2.11-0.9.0.1\kafka-logs
同样注意:路径要么是"/"分割,要么是转义字符"\",这样会生成正确的路径(层级,子目录)。错误路径情况可自行尝试,文件夹名为这种形式:bigdatakafka_2.11-0.9.0.1kafka-logs
③在server.properties文件中,zookeeper.connect=localhost:2181代表kafka所连接的zookeeper所在的服务器IP以及端口,可根据需要更改。本文在同一台机器上使用,故不用修改。
④kafka会按照默认配置,在9092端口上运行,并连接zookeeper的默认端口2181。
CMD进入安装目录 输入命令 .\bin\windows\kafka-server-start.bat .\config\server.properties 即可运行
注意:这个里面会报错,报找不到kafka.Kafka类
需要进入kafka-class-run文件里面改下配置。%ClassPath% 加上双引号"%ClassPath%"
