1.安装zookeeper

zookpeer下载地址:apache-zookeeper-3.7.1-bin.tar.gzhttps://link.csdn.net/?target=https%3A%2F%2Fwww.apache.org%2Fdyn%2Fcloser.lua%2Fzookeeper%2Fzookeeper-3.7.1%2Fapache-zookeeper-3.7.1-bin.tar.gz%3Flogin%3Dfrom_csdn

1.1解压安装zookeeper软件包（三个节点做）

cd /root

tar zxf apache-zookeeper-3.7.1-bin.tar.gz

mv apache-zookeeper-3.7.1-bin /usr/local/zookeeper-3.7.1

cd /usr/local/zookeeper-3.7.1/conf/

cp zoo_sample.cfg zoo.cfg

1.2 修改配置文件（第一个节点）

vim zoo.cfg

将zoo.cfg复制到其他两个节点

scp zoo.cfg 172.25.23.8:/usr/local/zookeeper-3.7.1/conf/

scp zoo.cfg 172.25.23.9:/usr/local/zookeeper-3.7.1/conf/

1.3 给每个机器指定对应的节点号

mkdir data logs

echo 1 > data/myid

mkdir data logs

echo 2 > data/myid

mkdir data logs

echo 3 > data/myid

cd /usr/local/zookeeper-3.7.1/bin

./zkServer.sh start

1.4 启动zookeeper

cd /usr/local/zookeeper-3.7.1/bin

./zkServer.sh start

1.5 开启之后，查看三个节点zookeeper状态

./zkServer.sh status

2、安装kafka

2.1 安装 kafka（3个节点都要操作）

cd /root

tar zxf kafka_2.13-2.7.1.tgz

mv kafka_2.13-2.7.1 /usr/local/kafka

2.2 修改配置文件（3个节点都要操作）

cd /usr/local/kafka/config/

vim server.properties

2.3 将相关命令加入到系统环境当中（3个节点都要操作）

vim /etc/profile

export KAFKA_HOME=/usr/local/kafka

export PATH=$PATH:$KAFKA_HOME/bin

source /etc/profile

2.4 启动kafka

cd /usr/local/kafka/config/

kafka-server-start.sh -daemon server.properties

netstat -antp | grep 9092

三个节点都启动

Kafka 命令行操作

创建topic

kafka-topics.sh --create --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181 --replication-factor 2 --partitions 3 --topic test

–zookeeper：定义 zookeeper 集群服务器地址，如果有多个 IP 地址使用逗号分割，一般使用一个 IP 即可

–replication-factor：定义分区副本数，1 代表单副本，建议为 2

–partitions：定义分区数

–topic：定义 topic 名称

查看当前服务器中的所有 topic

kafka-topics.sh --list --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181

查看某个 topic 的详情

kafka-topics.sh  --describe --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181

发布消息

kafka-console-producer.sh --broker-list 172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092  --topic test

消费消息

kafka-console-consumer.sh --bootstrap-server 172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092 --topic test --from-beginning

–from-beginning：会把主题中以往所有的数据都读取出来

修改分区数

kafka-topics.sh --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181 --alter --topic test --partitions 6

删除 topic

kafka-topics.sh --delete --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181 --topic test

2.5 创建topic

cd /usr/local/kafka/bin

kafka-topics.sh --create --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181 --partitions 3 --replication-factor 2 --topic wyn

kafka-topics.sh --describe --zookeeper 172.25.23.7:2181

2.6 测试topic

发布消息

kafka-console-producer.sh --broker-list 172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092 --topic wyn

kafka-console-producer.sh --broker-list 172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092 --topic wyn

消费消息

kafka-console-consumer.sh --bootstrap-server 172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092 --topic nginx-es --from-beginning

3、配置数据采集层filebeat（172.25.23.8）

安装nginx

cd /root

rpm -ivh nginx-1.20.0-1.el7.ngx.x86_64.rpm

3.1 定制日志格式

vim /etc/nginx/nginx.conf

log_format  json '{"@timestamp":"$time_iso8601",'

                           '"@version":"1",'

                           '"client":"$remote_addr",'

                           '"url":"$uri",'

                           '"status":"$status",'

                           '"domain":"$host",'

                           '"host":"$server_addr",'

                           '"size":$body_bytes_sent,'

                           '"responsetime":$request_time,'

                           '"referer": "$http_referer",'

                           '"ua": "$http_user_agent"'

               '}';



access_log  /var/log/nginx/access.log  json;

3.2 上传、解压安装包

cd /opt

rpm -ivh filebeat-5.5.0-x86_64.rpm

3.3 修改配置文件filebeat.yml

vim /etc/filebeat/filebeat.yml

3.4 启动filebeat

systemctl restart filebeat

systemctl status filebeat

查看端口是否打开

netstat -antp|grep filebeat

4、所有组件部署完成之后，开始配置部署

4.1 在kafka上创建一个话题nginx-es

cd /usr/local/kafka/bin

./kafka-topics.sh --create --zookeeper 172.25.23.7:2181,172.25.23.8:2181,172.25.23.9:2181 --replication-factor 1 --partitions 1 --topic nginx-es

./kafka-topics.sh --list --zookeeper 172.16.39.66:2181,172.16.39.70:2181,172.16.39.71:2181

4.2 修改logstash的配置文件

cd /etc/logstash/conf.d/

vim nginxlog.conf

input {

kafka {

    topics => "nginx-es"

    #codec => "json"

    decorate_events => true

    bootstrap_servers => ["172.25.23.7:9092,172.25.23.8:9092,172.25.23.9:9092"]

  }

}

output {

      elasticsearch {

      hosts => ["172.25.23.7:9200 "]

      index => "nginx-%{+YYYY-MM-dd}"

      }

  }

​​​​​​​systemctl restart logstash

systemctl status logstash

4.3 验证网页

cd /usr/local/src/node_modules/grunt/bin

./grunt server

4.4 Kibana上创建索引
