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
>>>:
[root@vm-0-5-centos config]# java --version
openjdk 11.0.16.1 2022-08-12 lts
openjdk runtime environment (red_hat-11.0.16.1.1-1.el7_9) (build 11.0.16.1+1-lts)
openjdk 64-bit server vm (red_hat-11.0.16.1.1-1.el7_9) (build 11.0.16.1+1-lts, mixed mode, sharing)

2.1 各个环境版本

  • 操作系统:centos 7
  • docker:20.10.18
  • docker-compose:2.4.1
  • elk version:7.4.2
  • filebeat:7.4.2
  • java:11.0.16.1

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=7.1.0 2.3 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:${es_version}"
        environment:
            - discovery.type=single-node
        volumes:
            - /etc/localtime:/etc/localtime
            - /elk/elasticsearch/data:/usr/share/elasticsearch/data
            - /elk/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
            - /elk/elasticsearch/plugins:/usr/share/elasticsearch/plugins
        ports:
            - "9200:9200"
            - "9300:9300"
    logstash:
        depends_on:
            - elasticsearch
        image: "docker.elastic.co/logstash/logstash:${es_version}"
        volumes:
            - /elk/logstash/config/conf.d/logstash.conf:/usr/share/logstash/pipeline/logstash.conf
        ports:
            - "5044:5044"
        links:
            - elasticsearch
​
    kibana:
        depends_on:
            - elasticsearch
        image: "docker.elastic.co/kibana/kibana:${es_version}"
        volumes:
            - /etc/localtime:/etc/localtime
            # kibana.yml配置文件放在宿主机目录下,方便后续汉化
            - /elk/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml
        ports:
            - "5601:5601"
        links:
            - elasticsearch
​
    filebeat:
        depends_on:
            - elasticsearch
            - logstash
        image: "docker.elastic.co/beats/filebeat:${es_version}"
        user: root # 必须为root
        environment:
            - strict.perms=false
        volumes:
            - /elk/filebeat/config/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
            # 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
        links:
            - logstash

3、在services中声明了四个服务

  • elasticsearch
  • logstash
  • kibana
  • filebeat

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-composeelasticsearch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-composefilebeat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:rw

⑤ 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

  #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

# 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
#migration.6_to_7.enabled: true

4.2 方法二

cd elk
#修改run.sh里面的es_host、log_host、kb_host
chmod +x ./run.sh  #使脚本具有执行权限
./run.sh  #执行脚本

5、启动

随后使用docker-compose命令启动:

docker-compose up -d
creating network "docker_repo_default" with the default driver
creating docker_repo_elasticsearch_1 ... done
creating docker_repo_kibana_1        ... done
creating docker_repo_logstash_1      ... done
creating docker_repo_filebeat_1      ... done
