kafka安装

前提条件：kafka依赖zookeeper，在安装kafka之前应安装并启动好zookeeper

zookeeper 1台：10.X.X.105

kafka 3台： 10.X.X.106/10.X.X.107/10.X.X.108

解压安装包

tar -zxvf  kafka_2.11-1.1.0.tgz

修改解压后的包名

mv kafka_2.11-1.1.0  kafka

修改配置文件

修改kafka配置文件，其中标黄部分为必须按需修改项

• 在10.X.X.106服务器上面

vim config/server.properties

• 在10.X.X.107服务器上面

vim config/server.properties

• 在10.X.X.108服务器上面

vim config/server.properties

注：#kafka部署的机器ip和提供服务的端口号

listeners=PLAINTEXT://10.X.X.108:9092

也可以写成

host.name=10.X.X.108

port=9092

启动集群

分别在106/107/108三台机器上启动kafka

./bin/kafka-server-start.sh -daemon ./config/server.properties

使用jps检查进程是否存在，如图进程存在

验证集群

./bin/kafka-topics.sh --create --zookeeper l0.X.X.105:2181 --replication-factor 1 --partitions 5 --topic my-topic

#创建一个my-topic 的 topic 、副本为1、分区数为5

创建完成后在各个服务器的logs目录下可以看到创建的my-topic

kafka-eagle安装

前提：已安装jdk、mysql

解压安装包

tar -zxvf  kafka-eagle-bin-2.0.6.tar.gz

cd  kafka-eagle-bin-2.0.6

tar -zxvf  kafka-eagle-web-2.0.6-bin.tar.gz

修改配置文件

vim conf/system-config.properties

注：如果想要监控集群各个服务器的CPU和内存使用情况在kafka安装目录下修改bin/kafka-server-start.sh文件

在最上面一行添加一行参数

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    export KAFKA_HEAP_OPTS="-Xmx4G -Xms4G"
    export JMX_PORT="9999"
fi

重启kafka即可

程序启动与停止

kafka-eagle-bin-2.0.6/kafka-eagle-web-2.0.6/bin目录下

执行./ke.sh start启动程序，如图启动成功

 执行./ke.sh stop 停止程序

问题解决

1.启动时如果报数据库表结构不存在，有两种解决办法

• 更换高版本安装
• 手动创建数据库表结构，表结构如下：

2.注意防火墙是否关闭，端口号是否开放

3.若果遇到类似下面的问题，可以先尝试把集群的所有kafka重新启动

其它

创建topic

./bin/kafka-topics.sh --create --zookeeper 10.X.X.105:2181 --replication-factor 1 --partitions 5 --topic my

手动删除topic

查看kafka下的topic：./bin/kafka-topics.sh --zookeeper 【zoserver】 --list
        ./bin/kafka-topics.sh --zookeeper 10.X.X.105:2181 --list
删除（做标记）：./bin/kafka-topics.sh --delete --zookeeper 【zoserver】 --topic 【topic name】
        ./bin/kafka-topics.sh --delete --zookeeper 10.X.X.105:2181 --topic  my
进入kafka的zookeeper客户端：./bin/zookeeper-shell.sh 10.X.X.105:2181
进入kafka的zookeeper后查看kafka下topic：ls /brokers/topics
真删除：rmr /brokers/topics 【topic name】
       rmr /brokers/topics my
