elk集群 docker-compose单节点运行版

机器分配

192.168.77.136 docker-compose

192.168.77.137 log-test cron

安装docker、docker-compose

centos

yum -y install docker-ce docker-compose

debian/ubuntu

apt -y install docker-ce docker-compose

编写docker-compose.yaml

mkdir /opt/elk
cd /opt/elk
vim docker-compose.yaml

内容如下

version: '3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.14.0
    environment:
      - node.name=elasticsearch
      - cluster.initial_master_nodes=elasticsearch
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    volumes:
      - data01:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
  logstash:
    image: docker.elastic.co/logstash/logstash:7.14.0
    volumes:
      - /var/log:/host/var/log
      - /opt/elk/pipeline:/usr/share/logstash/pipeline
    ports:
      - 5000:5000
  kibana:
    image: docker.elastic.co/kibana/kibana:7.14.0
    ports:
      - 5601:5601

volumes:
  data01:
    driver: local

编写日志收集配置文件(供参考)

##被收集日志赋权
chmod +x /var/log
chmod -R o+r /var/log
## 创建配置文件
mkdir /opt/elk/pipeline
cd /opt/elk/pipeline


[root@localhost pipeline]# cat logstash-cron.conf 
input {
  file {
    path => "/host/var/log/cron*"  # 调整为实际的 cron 日志路径
    start_position => "beginning"
    sincedb_path => "/dev/null"
    type => "cron"  # 这将在日志事件中添加一个字段,用于表示日志的类型
  }
}

filter {
  if [type] == "cron" {
    grok {
      match => { "message" => "%{GREEDYDATA:cron_message}" }
      add_field => { "source_ip" => "192.168.77.136" }  # 将这个 IP 地址更改为实际的源服务器 IP 地址
    }
  }
}

output {
  if [type] == "cron" {
    elasticsearch {
      hosts => ["192.168.77.136:9200"]
      index => "cron_%{source_ip}-%{+YYYY.MM.dd}"
    }
  }
  stdout { codec => rubydebug }
}

[root@localhost pipeline]# cat logstash-nginx.conf 
input {
  file {
    path => "/host/var/log/nginx/*"  # 调整为实际的 cron 日志路径
    start_position => "beginning"
    sincedb_path => "/dev/null"
    type => "nginx"  # 这将在日志事件中添加一个字段,用于表示日志的类型
  }
}

filter {
  if [type] == "nginx" {
    grok {
      match => { "message" => "%{GREEDYDATA:cron_message}" }
      add_field => { "source_ip" => "192.168.77.136" }  # 将这个 IP 地址更改为实际的源服务器 IP 地址
    }
  }
}

output {
  if [type] == "nginx" {
    elasticsearch {
      hosts => ["192.168.77.136:9200"]
      index => "nginx_%{source_ip}-%{+YYYY.MM.dd}"
    }
  }
  stdout { codec => rubydebug }
}

注意权限问题:对日志文件夹有执行权限,对日志文件有读取权限,关闭selinx

启停

cd /opt/elk
docker-compose up -d > elk.log
docker-compose down

其他日志收集服务器

mkdir /opt/elk
cd /opt/elk
cat logstash.yml 

http.host: "0.0.0.0"
xpack.monitoring.elasticsearch.hosts: [ "http://192.168.77.136:9200" ]

## 创建配置文件
mkdir /opt/elk/pipeline
cd /opt/elk/pipeline

input {
  file {
    path => "/host/var/log/cron*"  # 调整为实际的 cron 日志路径
    start_position => "beginning"
    sincedb_path => "/dev/null"
    type => "cron"  # 这将在日志事件中添加一个字段,用于表示日志的类型
  }
}

filter {
  if [type] == "cron" {
    grok {
      match => { "message" => "%{GREEDYDATA:cron_message}" }
      add_field => { "source_ip" => "192.168.77.137" }  # 将这个 IP 地址更改为实际的源服务器 IP 地址
    }
  }
}

output {
  if [type] == "cron" {
    elasticsearch {
      hosts => ["192.168.77.136:9200"]
      index => "cron_%{source_ip}-%{+YYYY.MM.dd}"
    }
  }
  stdout { codec => rubydebug }
}

##启动
  docker run --name elk_logstash_1 -d -p 5000:5000   -v /var/log:/host/var/log  -v /opt/elk/pipeline:/usr/share/logstash/pipeline  -v /opt/elk/logstash.yml:/usr/share/logstash/config/logstash.yml    docker.elastic.co/logstash/logstash:7.14.0
