Docker 搭建 ELK 收集并展示 Tomcat 日志

[日期:2019-08-13] 来源:Linux社区  作者:klvchen [字体: ]

架构

前端展示 --> 索引搜索 <-- 日志提取及过滤 --> 日志缓存 <-- 日志收集
Kibana --> Elastash <-- Logstash --> redis <-- filebeat

操作系统: CentOS 7.4
相关软件:filebeat-6.3.0-linux-x86_64.tar.gz, docker 18.03.1-ce, redis_version:4.0.10, docker-compose 1.18.0

日志文件名称及内容:

安装 filebeat

mkdir /home/tools -p

cd /home/tools

# 安装包上传到 /home/tools
tar zxvf filebeat-6.3.0-linux-x86_64.tar.gz -C /usr/local
cd /usr/local
ln -s /usr/local/filebeat-6.3.0-linux-x86_64 /usr/local/filebeat

配置 filebeat 配置文件

cd /usr/local/filebeat

cat filebeat4bossmobile.yml
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /iba/ibaboss/java/bossmobile-tomcat-8.0.26/logs/catalina.out
  multiline.pattern: '^[[:word:]]|^java' # 匹配多行时指定正则表达式
  multiline.negate: true # 定义上边pattern匹配到的行是否用于多行合并,也就是定义是不是作为日志的一部分,multiline 规则参考文章底下链接
  multiline.match: after # 定义如何将匹配到的行组合成,在之前或者之后
  fields:      # 在采集的信息中添加一个自定义字段 service,里面的值为 bossmobile_catalina,区分两类日志
    service: bossmobile_catalina

- type: log
  enabled: true
  paths:
    - /iba/ibaboss/java/bossmobile-tomcat-8.0.26/logs/ibalife.*
  multiline.pattern: '^\['
  multiline.negate: true
  multiline.match: after
  fields:      # 在采集的信息中添加一个自定义字段 service,里面的值为 bossmobile_ibalife,区分两类日志
    service: bossmobile_ibalife

output.redis:
  hosts: ["192.168.0.223"]               # 这里是 redis 的内网地址
  password: "ibalife"
  key: "bossmobile"                      # 存入到 redis 中的 bossmobile key 中
  db: 0
  timeout: 5

启动 filebeat

# 创建 filebeat 保存日志的文件夹
mkdir /iba/ibaboss/filebeat_logs

nohup ./filebeat -e -c filebeat4bossmobile.yml >/iba/ibaboss/filebeat_logs/filebeat4bossmobile.log 2>&1 & 

# 如果想重新读取日志,可以停止 filebeat 后删除,再重新启动即可
ps -ef|grep filebeat

kill -9 PID

rm /usr/local/filebeat/data/registry

安装配置 ELK

cd /home/ibaboss/compose

cat docker-compose-elk.yml 
version: '3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.2.4
    container_name: logs_elasticsearch           # 给容器命名
    restart: always
    environment:
      - discovery.type=single-node
      - cluster.name=docker-cluster
      - network.host=0.0.0.0
      - discovery.zen.minimum_master_nodes=1
      - ES_JAVA_OPTS=-Xms512m -Xmx512m
    volumes:
      - /iba/ibaboss/elk-data:/var/lib/elasticsearch
    networks:
      logs_elk:     # 指定使用的网络
        aliases:
          - elasticsearch     # 该容器的别名,在 logs_elk 网络中的其他容器可以通过别名 elasticsearch 来访问到该容器

  kibana:
    image: docker.elastic.co/kibana/kibana:6.2.4
    container_name: logs_kibana
    ports:
      - "5601:5601"
    restart: always
    networks:
      logs_elk:
        aliases:
          - kibana
    environment:
      - ELASTICSEARCH_URL=http://elasticsearch:9200
      - SERVER_NAME=kibana
    depends_on:
      - elasticsearch

  logstash:
    image: docker.elastic.co/logstash/logstash:6.2.4
    container_name: logs_logstash
    restart: always
    environment:
      - LS_JAVA_OPTS=-Xmx256m -Xms256m
    volumes:
      - ./config/logstash.conf:/etc/logstash.conf
    networks:
      logs_elk:
        aliases:
          - logstash
    depends_on:
      - elasticsearch
    entrypoint:
      - logstash
      - -f
      - /etc/logstash.conf

networks:
  logs_elk:
    external:
      name: logs_elk
cd /home/ibaboss/compose/config

cat logstash.conf

input {
        redis {
                port => "6379"                                    
                host => "elk_redis"             # redis 主机是 logs_elk 网络中的 elk_redis 主机
                data_type => "list"
                key  =>  "bossmobile"           # 从 redis 中 bossmobile key 中获取数据
                password => "ibalife"
        }

}

filter {        
     mutate { # 定义去除的字段
     remove_field => ["_id","@version","_index","_score","_type","beat.hostname","beat.name","beat.version","fields.service","input.type","offset","prospector.type","source"]
    }

  if [fields][service] == "bossmobile_catalina" {
    grok {   # 匹配 message 字段中的 时间,放入自定义的 customer_time 字段中
        match => [ "message" , "(?<customer_time>%{MONTHDAY}-%{MONTH}-%{YEAR} %{HOUR}:%{MINUTE}:%{SECOND})" ]
    }
  }
    
  if [fields][service] == "bossmobile_ibalife" {
    grok {
        match => [ "message" , "(?<customer_time>%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{HOUR}:%{MINUTE}:%{SECOND})" ]
    }
  }

    date {
       match => [ "customer_time", "dd-MMM-yyyy HH:mm:ss.SSS","yyyy-MM-dd HH:mm:ss" ]     # 格式化 customer_time 中的时间类型从string 变成 date,例如 22-Jun-2018 17:45:22.397,对应为 dd-MMM-yyyy HH:mm:ss.SSS
        locale => "en"
        target => [ "@timestamp" ]  # 替换 @timestamp 字段的值,@timestamp 的值用于 kibana 排序
        timezone => "Asia/Shanghai"
    }
 
}

output {  # 根据 redis 中的 service 的字段,分别创建不同的 elasticsearch index
  if [fields][service] == "bossmobile_catalina" {         
        elasticsearch {
                hosts => ["elasticsearch:9200"]
                index   => "bossmobile_catalina-%{+YYYY.MM.dd}"
        }
  }
  
  if [fields][service] == "bossmobile_ibalife" {
        elasticsearch {
                hosts => ["elasticsearch:9200"]
                index   => "bossmobile_ibalife-%{+YYYY.MM.dd}"
        }
  }

}

# 启动容器
mkdir /iba/ibaboss/elk-data -p
cd /home/ibaboss/compose
docker-compose -f docker-compose-elk.yml  up -d

docker ps -a

访问 kibana 所在的 ip:5601,创建 Index Patterns, bossmobile_catalina-* 和 bossmobile_ibalife-*


覆盖 -- overwrite

使用 Grok 的 overwrite 参数也可以覆盖日志中的信息

grok {
        match => { "message" => "\[%{WORD}\] \[%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{HOUR}:%{MINUTE}:%{SECOND}\]%{GREEDYDATA:message}" }
        overwrite => [ "message" ]
    }

这里会把 [ERROR] [2019-06-18 10:58:56] 这类信息去除
