1、组件介绍
在ELK Stack中同时包括了Elastic Search、LogStash、Kibana以及Filebeat；
各个组件的作用如下：
-
Filebeat：采集文件等日志数据；
-
LogStash：过滤日志数据；
-
Elastic Search：存储、索引日志；
-
Kibana：用户界面；
各个组件之间的关系如下图所示：
2 、项目环境
因为ElasticSearch是用Java语言编写的，所以必须安装JDK的环境，并且是JDK 1.8以上。
# 安装
sudo yum install java-11-openjdk -y# 安装完成查看java版本
java -version

2.2 Docker-Compose变量配置
首先，在配置文件
.env中统一声明了ES以及各个组件的版本：
.env
ES_VERSION=7.1.02.3 Docker-Compose服务配置
创建Docker-Compose的配置文件：
version: '3.4'
services:
elasticsearch:
image: "docker.elastic.co/elasticsearch/elasticsearch:${ES_VERSION}"
environment:
- discovery.type=single-node
volumes:
- /etc/localtime:/etc/localtime
- /elk/elasticsearch/data:/usr/share/elasticsearch/data
- /elk/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
- /elk/elasticsearch/plugins:/usr/share/elasticsearch/plugins
ports:
- "9200:9200"
- "9300:9300"

# 映射到容器中[作为数据源]
- /elk/filebeat/logs:/usr/share/filebeat/logs:rw
- /elk/filebeat/data:/usr/share/filebeat/data:rw
# 将指定容器连接到当前连接，可以设置别名，避免ip方式导致的容器重启动态改变的无法连接情况

3.1 ElasticSearch服务
创建docker容器挂在的目录
注意：chmod -R 777 /elk/elasticsearch 要有访问权限
mkdir -p /elk/elasticsearch/config/
mkdir -p /elk/elasticsearch/data/
mkdir -p /elk/elasticsearch/plugins/
echo "http.host: 0.0.0.0">>/elk/elasticsearch/config/elasticsearch.yml在elasticsearch服务的配置中有几点需要特别注意：
-
discovery.type=single-node：将ES的集群发现模式配置为单节点模式； -
/etc/localtime:/etc/localtime：Docker容器中时间和宿主机同步； -
/docker_es/data:/usr/share/elasticsearch/data：将ES的数据映射并持久化至宿主机中； -
/elk/elasticsearch/plugins:/usr/share/elasticsearch/plugins：将插件挂载到主机； -
/elk/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：将配置文件挂载到主机；
3.2 Logstash服务
创建docker容器挂在的目录
注意：chmod -R 777 /elk/logstash 要有访问权限
mkdir -p /elk/logstash/config/conf.d在logstash服务的配置中有几点需要特别注意：
-
/elk/logstash/config/conf.d/logstash.conf:/usr/share/logstash/pipeline/logstash.conf：将宿主机本地的logstash配置映射至logstash容器内部；
下面是LogStash的配置，在使用时可以自定义logstash.conf：
input {
# 来源beats
beats {
# 端口
port => "5044"
}
}
output {
elasticsearch {
hosts => ["http://elasticsearch:9200"]
index => "test"
}
stdout { codec => rubydebug }
}在这里我们将原来tcp收集方式修改为由filebeat上报，同时固定了索引为test；
3.3 Kibana服务
创建docker容器挂在的目录
注意：chmod -R 777 /elk/kibana 要有访问权限
mkdir -p /elk/kibana/config在kibana服务的配置中有几点需要特别注意：
-
/elk/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml：配置ES的地址； -
/etc/localtime:/etc/localtime：Docker容器中时间和宿主机同步；
修改 kibana.yml 配置文件，新增(修改)配置项i18n.locale: "zh-CN"
[root@VM-0-5-centos ~]# cd /mydata/kibana/config
[root@VM-0-5-centos config]# cat kibana.yml
# Default Kibana configuration for docker target
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://elasticsearch:9200" ]
xpack.monitoring.ui.container.elasticsearch.enabled: true
i18n.locale: "zh-CN" # 设置为中文
[root@VM-0-5-centos config]# 3.4 Filebeat服务
注意：chmod -R 777 /elk/filebeat 要有访问权限
创建docker容器挂在的目录
mkdir -p /elk/filebeat/config
mkdir -p /elk/filebeat/logs
mkdir -p /elk/filebeat/data在Filebeat服务的配置中有几点需要特别注意
-
配置
user: root和环境变量strict.perms=false：如果不配置可能会因为权限问题无法启动；
volumes:
- - /elk/filebeat/config/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
+ - <your_log_path>/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
- - /elk/filebeat/logs:/usr/share/filebeat/logs:rw
+ - <your_log_path>:/usr/share/filebeat/logs:rw
- - /elk/filebeat/data:/usr/share/filebeat/data:rw
+ - <your_data_path>:/usr/share/filebeat/logs:rw同时还需要创建Filebeat配置文件：
filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
# 容器中目录下的所有.log文件
- /usr/share/filebeat/logs/*.log
multiline.pattern: ^\[
multiline.negate: true
multiline.match: after
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 1
setup.dashboards.enabled: false
setup.kibana:
host: "http://kibana:5601"
# 直接传输至ES
#output.elasticsearch:
# hosts: ["http://es-master:9200"]
# index: "filebeat-%{[beat.version]}-%{+yyyy.MM.dd}"
# 传输至LogStash
output.logstash:
hosts: ["logstash:5044"]
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~上面给出了一个filebeat配置文件示例，实际使用时可以根据需求进行修改；
4、使用方法
4.1 方法一
使用前必看：
① 修改ELK版本
可以修改在.env中的ES_VERSION字段，修改你想要使用的ELK版本；
② LogStash配置
修改logstash.conf为你需要的日志配置；
③ 修改ES文件映射路径
修改docker-compose中elasticsearch服务的volumes，将宿主机路径修改为你实际的路径：
volumes:
- /etc/localtime:/etc/localtime
- - /docker_es/data:/usr/share/elasticsearch/data
+ - [your_path]:/usr/share/elasticsearch/data并且修改宿主机文件所属：
sudo chown -R 1000:1000 [your_path]④ 修改filebeat服务配置
修改docker-compose中filebeat服务的volumes，将宿主机路径修改为你实际的路径：
volumes:
- ./filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
- - /elk/filebeat/logs:/usr/share/filebeat/logs:rw
+ - <your_log_path>:/usr/share/filebeat/logs:rw
- - /elk/filebeat/data:/usr/share/filebeat/data:rw
+ - <your_data_path>:/usr/share/filebeat/logs:rw⑤ 修改Filebeat配置
修改filebeat.yml为你需要的配置；
Filebeat配置文件详情参见如下：
[vagrant@localhost filebeat-7.7.1]$ vi filebeat.yml
###################### Filebeat Configuration Example #########################
#=========================== Filebeat inputs =============================

# you can use different inputs for various configurations.
#您可以为各种配置使用不同的输入。
# Below are the input specific configurations.
#下面是特定于输入的配置。

# Paths that should be crawled and fetched. Glob based paths.
#应该被爬取的路径。基础路径。
paths:
#可配置多个路径

### Multiline options
# Multiline can be used for log messages spanning multiple lines. This is common
# Multiline可用于记录跨多行的消息。这是常见的
# for Java Stack Traces or C-Line Continuation
#用于Java堆栈跟踪或c行延续
# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#必须匹配的regexp模式。示例模式匹配以[开头的所有行
multiline.pattern: ^\[
# Defines if the pattern set under pattern should be negated or not. Default is false.
#定义模式下的模式集是否应该被否定。默认是false
multiline.negate: true
# Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
#Match可以设置为“after”或“before”。它用于定义是否应该将行追加到模式中
# that was (not) matched before or after or as long as a pattern is not matched based on negate.
#在之前或之后匹配的，或者只要模式没有基于negate匹配。
# Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
#注意:在Logstash中，After等同于previous, before等同于next
multiline.match: after

- add_kubernetes_metadata: ~
#================================ Logging =====================================
# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: debug
# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",

#logging.selectors: ["*"]
#============================== X-Pack Monitoring ===============================
# filebeat can export internal metrics to a central Elasticsearch monitoring
# cluster. This requires xpack monitoring to be enabled in Elasticsearch. The
# reporting is disabled by default.
# Set to true to enable the monitoring reporter.
#monitoring.enabled: false
# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch
# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.
#monitoring.cluster_uuid:
# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch
# output configuration, so if you have the Elasticsearch output configured such
# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.
#monitoring.elasticsearch:
#================================= Migration ==================================
# This allows to enable 6.7 migration aliases
