一、Elasticsearch docker安装[1]
准备Dockerfile和资源文件
elasticsearch.yml(elasticsearch配置文件)
elasticsearch-6.2.4.tar.gz(安装包，官网下载)
elasticsearch-analysis-ik-6.2.4.zip(分词器插件，官网下载)
supervisord.conf (supervisord启动配置文件,也可不用supervisord启动，直接用./elasticsearch)
1. 配置文件elasticsearch.yml
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: elasticsearch-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#只启动一个节点
#避免failed to obtain node locks, tried， maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes..
node.max_local_storage_nodes: 1
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#索引数据的存储路径
path.data: /usr/local/elasticsearch/data
#日志文件的存储路径
path.logs: /usr/local/elasticsearch/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#
http.port: 9200
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
2. supervisord.conf
[supervisord]
nodaemon=true

user=elsearch
stdout_logfile_maxbytes = 20MB
stdout_logfile = /usr/local/elasticsearch/logs/elasticsearch-application.log
3. Dockerfile
#

You probably need to set vm.max_map_count in /etc/sysctl.conf on the host itself, so that Elasticsearch does not attempt to do that from inside the container.
If you don't know the desired value, try doubling the current setting and keep going until Elasticsearch starts successfully.
Documentation recommends at least 262144.
解决方法:
#在 宿主机 切换为root用户,修改内核参数为262144
#临时生效
sysctl vm.max_map_count=262144
#永久生效
echo "vm.max_map_count=262144" >> /etc/sysctl.conf
sysctl -p
failed to obtain node locks, tried，
maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes..
解决方法: 这里使用的是简单配置，单节点， 在elasticsearch.yml
node.max_local_storage_nodes: 1
二、 docker Kafka和zookeeper安装[2]
这里直接采用wurstmeister/kafka-docker 的docker 镜像,没有使用kafka自带的zookeeper
三、 docker Logstash安装[3]
Logstash 6.3官方文档 : https://www.elastic.co/guide/en/logstash/6.3/index.html
准备Dockerfile和资源文件
Dockerfile
logstash.conf (logstash输入源、输出源、过滤规则等配置文件)
logstash.yml (logstash环境配置)
logstash-6.3.0.tar.gz (安装包)
1. logstash.conf 文件
input{
kafka{
bootstrap_servers => ["192.168.243.195:9092"]
group_id => "es-consumer-group"
auto_offset_reset => "latest" #从最新的偏移量开始消费
consumer_threads => 5
decorate_events => true #此属性会将当前topic、offset、group、partition等信息也带到message中
topics => ["Microservice"] #kafka 的topic
}
#可以设置多个
# kafka{
# bootstrap_servers => ["192.168.243.195:9092"]
# client_id => "test2"
# group_id => "test2"
# auto_offset_reset => "latest"
# consumer_threads => 5
# decorate_events => true
# topics => ["logq"]
# type => "student"
# }
}
output {
elasticsearch{
hosts=> ["192.168.243.195:9200"]
index=> "microservice-%{+YYYY.MM.dd}" #这里配置微服务索引,如果没有创建索引，会自动创建，会根据日期生成索引，20190802 则会生成 microservice-2019.08.02索引
}
}
2. logstash.yml 文件(监控没配置X-pack插件，不会有登陆和Monitoring菜单)
http.host: "0.0.0.0"
log.level: info # 默认为info ,当消费数据失败，无法发现错误时候可以使用debug模式查看日志
path.logs: /opt/logs/logstash
# xpack.monitoring.elasticsearch.url: http://192.168.243.195:9200 #监控es健康状态
# xpack.monitoring.elasticsearch.username: elastic
# xpack.monitoring.elasticsearch.password: changeme
# xpack.monitoring.enabled: false
3. Dockerfile 文件
#
# logstash-6.3.0 服务
#
FROM centos7-base
MAINTAINER xuchang
ADD logstash-6.3.0.tar.gz /opt/soft/
WORKDIR /opt/soft/
COPY logstash.conf /opt/soft/logstash-6.3.0/bin/logstash.conf

RUN mkdir -p /opt/soft/logs
ENTRYPOINT /opt/soft/logstash-6.3.0/bin/logstash -f /opt/soft/logstash-6.3.0/bin/logstash.conf
四、 docker Kibana安装[4]
准备Dockerfile和资源文件
Dockerfile
kibana.yml (kibana环境配置)
kibana-6.2.4-linux-x86_64.tar.gz (安装包)
supervisord.conf (supervisord启动配置文件,也可不用supervisord启动，直接用./kibana)
1. kibana.yml
# Kibana is served by a back end server. This setting specifies the port to use.
server.port: 5601
# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "0.0.0.0"
# Enables you to specify a path to mount Kibana at if you are running behind a proxy. This only affects
# the URLs generated by Kibana, your proxy is expected to remove the basePath value before forwarding requests
# to Kibana. This setting cannot end in a slash.
#server.basePath: ""
# The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576
# The Kibana server's name. This is used for display purposes.
#server.name: "your-hostname"
# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://192.168.243.195:9200"
2. supervisord.conf

1. 根据kafka的容器Id推送数据
docker exec -ti 0ba972877a7e bin/kafka-topics.sh --create --zookeeper 192.168.243.195:2181 --replication-factor 1 --partitions 1 --topic Microservice
docker exec -ti 0ba972877a7e kafka-console-producer.sh --broker-list 192.168.243.195:9092 --topic Microservice
> sasasasasasa
> test1111111
发送两条sasasasasasa、test1111111，
发送数据后，elasticsearch作为output源,会在es中自动创建logstash.conf中的索引，由于这里采用的是日期通配，所有会创建一条microservice-2019.08.02的索引，
数据流向 kafka->logstash->elasticsearch
2. Kibana创建索引
1.登陆Kibana Web界面 http://{local-ip}:5601/
2.点击左边菜单 Management
1. 点击 * 左下角 [Index Patterns]
2. 左边列表点击 [ Create Index Pattern]
3.界面显示:
Step 1 of 2: Define index pattern
Index pattern
<这个位置填写匹配需要的索引>
You can use a * as a wildcard in your index pattern.
You can't use empty spaces or the characters \, /, ?, ", <, >, |.
4.点击下一步，保存完成
3.通过Kibana查看数据
点击Kibana左侧菜单 discover
