拓扑：
安装JDK
不管需不需要，都装上JDK吧，省的麻烦，我这里装的是jdk1.8.0_151
tar xf jdk-8u151-linux-x64.tar.gz -C /opt/
配置环境变量
vim /etc/profile
export JAVA_HOME=/opt/jdk1.8.0_151
export PATH=$JAVA_HOME/bin:$PATH
source /etc/profile
安装zk
以192.168.0.156为例
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz
tar xf zookeeper-3.4.14.tar.gz -C /opt/
# 修改配置信息
cd /opt/zookeeper-3.4.14/conf
cp zoo_sample.cfg zoo.cfg
修改zk配置文件：
# vim zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/elk/zk/data/
clientPort=2181
server.1=192.168.0.156:12888:13888
server.2=192.168.0.42:12888:13888
server.3=192.168.0.133:12888:13888
创建数据目录，添加zk的竞选ID：
# 添加数据目录
mkdir -p /data/elk/zk/data/
# 192.168.0.156上
echo 1 > /data/elk/zk/data/myid
# 192.168.0.42上
echo 2 > /data/elk/zk/data/myid
# 192.168.0.133上
echo 3 > /data/elk/zk/data/myid
其他两台的配置一样，除了myid不同。
启动三台ZK
./bin/zkServer.sh start
查看状态，输出如下表示ZK集群OK了
./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: follower
安装Kafka
wget https://www-us.apache.org/dist/kafka/2.2.0/kafka_2.11-2.2.0.tgz
tar xf kafka_2.11-2.2.0.tgz -C /opt/
# 配置文件
cd /opt/kafka_2.11-2.2.0/config
修改配置文件：
# vim server.properties
broker.id=1
listeners=PLAINTEXT://192.168.0.156:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/data/elk/kafka/logs
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=192.168.0.156:2181,192.168.0.42:2181,192.168.0.133:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
另外两台配置信息需要改动的地方分别是broker.id=2和3，listeners改成自己本机IP。
创建日志目录：
mkdir -p /data/elk/kafka/logs
配置hosts：
kafka01 192.168.0.156
kafka02 192.168.0.42
kafka03 192.168.0.133
启动三台kafka
../bin/kafka-server-start.sh -daemon server.properties
测试：
（1）、创建topic
../bin/kafka-topics.sh --create --zookeeper 192.168.0.156:2181 --replication-factor 1 --partitions 2 --topic message_topic
（2）、查看topic
../bin/kafka-topics.sh --list --zookeeper 192.168.0.156:2181
（3）、测试消费者，生产者
# 在其中一台执行以下命令
./bin/kafka-console-consumer.sh --bootstrap-server 192.168.0.156:9092 --topic message_topic --from-beginning
# 另开一个终端执行以下命令
../bin/kafka-console-producer.sh --broker-list 192.168.0.156:9092 --topic message_topic
>hello
>
# 就会输出以下内容
./bin/kafka-console-consumer.sh --bootstrap-server 192.168.0.156:9092 --topic message_topic --from-beginning
hello
安装logstash
wget https://artifacts.elastic.co/downloads/logstash/logstash-7.1.1.tar.gz
tar xf logstash-7.1.1.tar.gz -C /opt/
修改配置文件
vim logstash.yml
path.data: /data/elk/logstash/data

tar xf elasticsearch-7.1.1-linux-x86_64.tar.gz -C /opt/
配置elasticsearch.yml
node.name: node02
path.data: /data/elk/data
path.logs: /data/elk/logs
network.host: 192.168.0.169
http.port: 9200
discovery.seed_hosts: ["node01", "node02"]
cluster.initial_master_nodes: ["node01", "node02"]
另外一台配置更改node.name和network即可。
创建普通用户
useradd elastic
chown elastic.elastic elasticsearch-7.1.1/ -R
创建数据日志目录
mkdir -p /data/elk/{data,logs}
chown elastic.elastic /data -R
配置内核参数和文件描述符
vim /etc/stsctl.conf
fs.file-max=65536
vm.max_map_count = 262144
sysctl -p
vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536

示例nginx
在nginx服务器上配置filebeat
首先部署filebeat。
修改配置文件：
# vim filebeat.yml
filebeat.inputs:
- type: log

paths:
- /var/log/*.log
- type: log
enable: true
paths:
- /var/log/nginx/access.log

启动服务：
nohup ./filebeat &
在logstash上配置获取日志
配置文件：
# vim opt/logstash-7.1.1/config/conf.d/nginx.conf
input {
kafka {
codec => "json"
topics => ["nginx-topic"]
bootstrap_servers => ["192.168.0.156:9092, 192.168.0.42:9092, 192.168.0.133:9092"]
group_id => "logstash-g1"
}
}
output {
elasticsearch {
hosts => ["192.168.0.87:9200", "192.168.0.169:9200"]
index => "logstash-%{+YYYY.MM.dd}"
}
}
启动服务：
nohup ../../bin/logstash -f ../conf.d/nginx.conf &
在ES上查看索引
curl '192.168.0.87:9200/_cat/indices?v'

green open logstash-2019.06.17-000001 vNCkz0a2R8unLxr5m9dSWg 1 1 2 0 82.1kb 41kb
在kibana上添加索引
在NG的机器上随便curl以下：
# curl localhost/121231
日志比较乱，是因为我们没做日志的过滤。
