    export PATH=${JAVA_HOME}/bin:$PATH

source /etc/profile
java -version

2、安装zookeeper

#下载zookeeper
https://zookeeper.apache.org/
#解压
tar -xzvf apache-zookeeper-3.5.5-bin.tar.gz
mv apache-zookeeper-3.5.5-bin zookeeper
cd /www/softs/zookeeper
mkdir /www/softs/zookeeper/data
#修改配置文件
cp conf/zoo_sample.cfg conf/zoo.cfg
vim conf/zoo.cfg
    dataDir=/www/softs/zookeeper/data
    server.1=172.19.60.175:2888:3888
    server.2=172.19.60.174:2888:3888

【服务器-1】
echo "1" > /www/softs/zookeeper/data/myid
【服务器-2】
echo "2" > /www/softs/zookeeper/data/myid

#启动服务
/www/softs/zookeeper/bin/zkServer.sh start
/www/softs/zookeeper/bin/zkServer.sh status
/www/softs/zookeeper/bin/zkServer.sh stop
/www/softs/zookeeper/bin/zkServer.sh restart
【从服务器显示状态】
Mode: follower
【主服务器显示状态】
Mode: leader

3、安装kafka

#下载
https://www.apache.org/dyn/closer.cgi?path=/kafka/1.0.0/kafka_2.12-1.0.0.tgz

mv kafka_2.12-2.2.1 kafka

#编辑配置文件
vim /www/softs/kafka/config/server.properties
【服务器-1】
broker.id=0
port=9092
log.dirs=/www/softs/kafka/kafka-logs
listeners=PLAINTEXT://192.168.10.41:9092

4、命令

# 启动zookeeper
/www/softs/kafka/bin/zookeeper-server-start.sh -daemon /www/softs/kafka/config/zookeeper.properties

# 启动broker
nohup /www/softs/kafka/bin/kafka-server-start.sh /www/softs/kafka/config/server.properties 1>/dev/null 2>&1 &

# 停止zookeeper
/www/softs/kafka/bin/zookeeper-server-stop.sh

# 停止broker
/www/softs/kafka/bin/kafka-server-stop.sh

# 创建topic
/www/softs/kafka/bin/kafka-topics.sh --create --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --replication-factor 1 --partitions 6 --topic test

# 查看所有topic
/www/softs/kafka/bin/kafka-topics.sh --list --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092

# 查看单个topic信息
/www/softs/kafka/bin/kafka-topics.sh --describe --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --topic test

# 给topic增加partitions
/www/softs/kafka/bin/kafka-topics.sh --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --alter --topic test --partitions 6

# 生产消息
/www/softs/kafka/bin/kafka-console-producer.sh --broker-list 172.19.60.175:9092,172.19.60.174:9092 --topic test

# 消费消息
/www/softs/kafka/bin/kafka-console-consumer.sh --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --topic test --from-beginning

# 删除topic

# 检测消费者位置
/www/softs/kafka/bin/kafka-consumer-groups.sh --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --describe --group test

# 查看消费者状态
/www/softs/kafka/bin/kafka-consumer-groups.sh --bootstrap-server 172.19.60.175:9092,172.19.60.174:9092 --describe --group test

# 杀死进程
ps -ef | grep java | grep -v grep | awk '{print $2}' | xargs kill -9

# 清除日志
rm -rf /tmp/kafka-logs/ && rm -rf /tmp/zookeeper/ && rm -rf /home/kafka/logs/*

5、PHP扩展

# kafka php库
# 下载源码librdkafka
    https://github.com/edenhill/librdkafka.git
cd librdkafka-master
./configure
make && make install

# 安装php kafka扩展 php-rdkafka extension
# 下载源码
    https://github.com/arnaud-lb/php-rdkafka.git
    
# 编译安装
unzip php-rdkafka-master.zip
cd php-rdkafka-master
/www/server/php/72/bin/phpize
./configure --with-php-config=/www/server/php/72/bin/php-config
make && make install

# 查看.so名称
ls /www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/
# 修改php.ini
extension = /www/server/php/72/lib/php/extensions/no-debug-non-zts-20170718/rdkafka.so
# 重启php，查看phpinfo，搜索kafka，找到即成功
# 使用示例:
    https://arnaud-lb.github.io/php-rdkafka/phpdoc/rdkafka.examples.html
