ELK搭建教程

本文介绍了基于Docker的ELK搭建教程，以及使用ELK收集springboot logback的操作日志。

拉取镜像

docker pull elasticsearch:6.4.0
docker pull logstash:6.4.0
docker pull kibana:6.4.0

配置 es

创建插件文件目录：/usr/local/docker/elasticsearch/plugins
创建数据文件目录：/usr/local/docker/elasticsearch/data

配置 logstash

创建 logstash 配置文件：/usr/local/docker/logstash/logstash.conf

logstash.conf 文件配置：

input {
  tcp {
    # Logstash 作为服务
    mode => "server"
    host => "0.0.0.0"
    # 开放9001端口进行采集日志
    port => 4560
    # 编解码器
    codec => json_lines
  }
}
output {
  elasticsearch {
    # 配置ES的地址
    hosts => "es:9200"
    # 在ES里产生的index的名称
    index => "springboot-logstash-%{+YYYY.MM.dd}"
    
    #user => "elastic" 
    #password => "changeme"
  }
}

注意：总体来讲，127.0.0.1是本机的环回地址，0.0.0.0代表本机上任何IP地址。

创建容器

docker-compose.yml 文件配置

version: '3'
services:
  elasticsearch:
    image: elasticsearch:6.4.0
    container_name: elasticsearch
    environment:
      - "discovery.type=single-node" #以单一节点模式启动
      - "ES_JAVA_OPTS=-Xms256m -Xmx256m" #设置使用jvm内存大小
    volumes:
      - /usr/local/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins #插件文件挂载
      - /usr/local/docker/elasticsearch/data:/usr/share/elasticsearch/data #数据文件挂载
    ports:
      - 9200:9200
      - 9300:9300
  kibana:
    image: kibana:6.4.0
    container_name: kibana
    links:
      - elasticsearch:es #可以用es这个域名访问elasticsearch服务
    depends_on:
      - elasticsearch #kibana在elasticsearch启动之后再启动
    environment:
      - "elasticsearch.hosts=http://es:9200";  #设置访问elasticsearch的地址
    ports:
      - 5601:5601
  logstash:
    image: logstash:6.4.0
    container_name: logstash
    volumes:
      - /usr/local/docker/logstash/logstash.conf:/usr/share/logstash/pipeline/logstash.conf #挂载logstash的配置文件
    depends_on:
      - elasticsearch #kibana在elasticsearch启动之后再启动
    links:
      - elasticsearch:es #可以用es这个域名访问elasticsearch服务
    ports:
      - 4560:4560

ELK 收集 springboot logback 日志

<!--集成logstash-->
<dependency>
    <groupId>net.logstash.logback</groupId>
    <artifactId>logstash-logback-encoder</artifactId>
    <version>5.3</version>
</dependency>

logback.xml 文件配置：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    
    <!--应用名称-->
    <property name="APP_NAME" value="mall-admin"/>
    
    <!--日志文件保存路径-->
    <property name="LOG_FILE_PATH" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}}/logs}"/>
    <contextName>${APP_NAME}</contextName>
    
    <!--每天记录日志到文件appender-->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_FILE_PATH}/${APP_NAME}-%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${FILE_LOG_PATTERN}</pattern>
        </encoder>
    </appender>
    
    <!--输出到logstash的appender-->
    <appender name="LOGSTASH" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
        <!--可以访问的logstash日志收集端口-->
        <destination>192.168.3.101:4560</destination>
        <encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder"/>
    </appender>
    
    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
        <appender-ref ref="LOGSTASH"/>
    </root>
    
</configuration>
