微服務日誌監控系統ELK之docker-compose搭建ELK

docker-compose搭建日誌監控系統ELK

1、基礎環境

環境要求

服務器：centos 7.0

環境： docker、dockers-compose

內存： 4G

2、環境配置

elasticsearch需要設置系統內核參數，否則會因爲內存不足無法啓動。

# 改變設置
sysctl -w vm.max_map_count=262144
# 使之立即生效
sysctl -p

3、配置啓動docker-compose.yml

創建logstash的配置文件 logstash-springboot.conf

input {
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 4560
    codec => json_lines
  }
}
output {
  elasticsearch {
    hosts => "es:9200"
    index => "ms-%{+YYYY.MM.dd}" 
  }
}

啓動文件 docker-compose.yml

version: '3'
services:
  elasticsearch:
    image: elasticsearch:6.4.0
    container_name: elasticsearch
    environment:
      - "cluster.name=elasticsearch" #設置集羣名稱爲elasticsearch
      - "discovery.type=single-node" #以單一節點模式啓動
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m" #設置使用jvm內存大小
      - TZ=Asia/Shanghai
    volumes:
      - /data/elk/elasticsearch/plugins:/usr/share/elasticsearch/plugins #插件文件掛載
      - /data/elk/elasticsearch/data:/usr/share/elasticsearch/data #數據文件掛載
    ports:
      - 9200:9200
  kibana:
    image: kibana:6.4.0
    container_name: kibana
    links:
      - elasticsearch:es #可以用es這個域名訪問elasticsearch服務
    depends_on:
      - elasticsearch #kibana在elasticsearch啓動之後再啓動
    environment:
      - "elasticsearch.hosts=http://es:9200" #設置訪問elasticsearch的地址
      - TZ=Asia/Shanghai
    ports:
      - 5601:5601
  logstash:
    image: logstash:6.4.0
    container_name: logstash
    volumes:
      - /data/elk/logstash/logstash-springboot.conf:/usr/share/logstash/pipeline/logstash.conf #掛載logstash的配置文件
    environment:
      - TZ=Asia/Shanghai #環境設置時區
    depends_on:
      - elasticsearch #kibana在elasticsearch啓動之後再啓動
    links:
      - elasticsearch:es #可以用es這個域名訪問elasticsearch服務
    ports:
      - 4560:4560

給掛載目錄授權

chmod 777 /data/elk/elasticsearch/plugins
chmod 777 /data/elk/elasticsearch/data

在docker-compose.yml文件夾下執行 命令啓動服務

docker-compose up -d

執行啓動成功

在logstash中安裝json_lines插件

# 進入logstash容器
docker exec -it logstash /bin/bash
# 進入bin目錄
cd /bin/
# 安裝插件
logstash-plugin install logstash-codec-json_lines
# 退出容器
exit
# 重啓logstash服務
docker restart logstash

關閉防火牆，或開啓相關接口即可訪問kibana.

systemctl stop firewalld

通常ELK可應用微服務的日誌收集，線上查看，日誌統計等。

4.spring booot輸出日誌到ELK

spring boot日誌中配置logback.xml向logstash中發送日誌。

配置文件如下：

    <!-- 微服務資源配置文件 -->
