一.安装elasticsearch

# 安装es
docker pull elasticsearch:7.17.3
mkdir -p /mydata/elasticsearch/config
mkdir -p /mydata/elasticsearch/data
echo "http.host: 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml
chmod -R 777 /mydata/elasticsearch/

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
--restart=always --privileged=true \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.17.3

1.1进入到es挂载目录elasticsearch.yml的挂载目录，添加以下内容

http.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl.enabled: true
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl.enabled: false

1.2 重启es容器并进入es容器
1.3 进入容器后执行以下命令傻瓜式设置账号密码

./bin/elasticsearch-setup-passwords interactive

1.4 重启es容器

二. 安装kibana

# 安装es可视化工具kibana
docker pull kibana:7.17.3

docker run -d -p 5601:5601 \
--restart=always \
-v /mydata/kibana/kibana.yml:/usr/share/kibana/config/kibana.yml \
--name kibana \
kibana:7.4.2

2.1 配置kibana连接es
进入挂载文件 /mydata/kibana/kibana.yml


server.port: 5601 
#主机地址，可以是ip,主机名
server.host: 0.0.0.0
elasticsearch.hosts: ["http://127.0.0.1:9200"]
xpack.monitoring.ui.container.elasticsearch.enabled: true
elasticsearch.username: "es账号"
elasticsearch.password: "es密码"
i18n.locale: "zh-CN"

2.2 访问 http://ip:9200,http://ip:5601看es,kibana是否安装完成

三.配置logstash

# logstash安装
 docker run -d --name logstash \
 -p 5043:5043 -p 5044:5044  --privileged=true \
 -v /mydata/logstash/logstash.conf:/usr/share/logstash/pipeline/logstash.conf \
 -v /mydata/logstash/logstash.yml:/usr/share/logstash/config/logstash.yml \
 logstash:7.17.3

3.1 进入logstash容器执行以下命令:

docker exec -it logstash /bin/bash

/usr/share/logstash/bin/logstash-plugin install logstash-codec-json_lines

3.2 重启logstash
3.3 进入logstash容器的挂载目录logstash.conf

input {
  stdin { }

  tcp {
      mode => "server"
      host => "0.0.0.0"
      port => 5043
      codec => json_lines
  }
}

output {
  stdout {
    codec => rubydebug
  }
  elasticsearch {
    hosts => "192.168.1.1:9200"
    index => "springboot-%{+YYYY.MM.dd}"
    user => "es账号"
    password => "es密码"
  }
}

这里认证明文不安全.可以参考如下链接: 密文

四.springboot整合logstash

1.pom.xml

<dependency>
   <groupId>ch.qos.logback</groupId>
   <artifactId>logback-classic</artifactId>
</dependency>
<dependency>
   <groupId>net.logstash.logback</groupId>
   <artifactId>logstash-logback-encoder</artifactId>
   <version>7.3</version>
</dependency>

2. application.yml

server:
  port: 10500

spring:
  profiles:
      active: dev
  application:
    name: vector-search
  thymeleaf:
    cache: false
  # jackson时间格式化
  jackson:
    time-zone: GMT+8
  # elasticsearch
    date-format: yyyy-MM-dd HH:mm:ss

logging:
  level:
    root: info

3.application-dev.yml

logstash:
  host: 127.0.0.1
  port: 5043
  # 定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径
  path: /mydata/logstash
es:
  host: 127.0.0.1
  port: 9200
  username: 11111
  password: 11111

4.在resources文件夹下，创建logback-spring.xml而不是logback.xml.该配置放在公共模块,当依赖导入其他微服务模块即可实现多模块收集日志到logstash中.
在这里插入图片描述
