1.部署单点`ElasticSearch`

因为我们还需要部署kibana容器，因此需要让ElasticSearch和kibana容器互联。这里先创建一个网络：

# 建创建bridge网络

docker network create es-net

# 查看docker 网络

docker network ls

# 查看mysqlnet网络详细信息

docker network inspect es-net

1.2.拉取镜像

考虑到ElasticSearch的兼容性，这里ElasticSearch、kibana统一下载8.8.1版本

# 拉取镜像
docker pull elasticsearch:8.8.1

1.3.第一次执行`docker`脚本

docker run -it \
    -p 9200:9200 \
    -p 9300:9300 \
    --name es \
    --net es-net \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
    -e "discovery.type=single-node" \
    -e LANG=C.UTF-8 \
    -e LC_ALL=C.UTF-8 \
    elasticsearch:8.6.2

1.4.创建`Elasticsearch`挂载目录

mkdir -p ~/data/elasticsearch

1.5.给创建的文件夹授权

sudo chown -R 1000:1000 ~/data/elasticsearch

1.6.将容器内的文件复制到主机上

docker cp es:/usr/share/elasticsearch/config ~/data/elasticsearch
docker cp es:/usr/share/elasticsearch/data ~/data/elasticsearch
docker cp es:/usr/share/elasticsearch/plugins ~/data/elasticsearch
docker cp es:/usr/share/elasticsearch/logs ~/data/elasticsearch

1.7.删除容器

docker rm -f es

1.8.修改`docker`脚本，增加-v挂载目录和-d参数

docker run -d \
	--name es \
    --privileged \
    --network es-net \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
    -e "discovery.type=single-node" \
 	-e LANG=C.UTF-8 \
 	-e LC_ALL=C.UTF-8 \
    -p 9200:9200 \
    -p 9300:9300 \
    -v es-data:~/data/elasticsearch/data \
    -v es-plugins:~/data/elasticsearch/plugins \
    -v es-logs:~/data/elasticsearch/logs \
elasticsearch:8.8.1

1.9.修改配置`~/data/elasticsearch/config/elasticsearch.yml`：

增加：xpack.monitoring.collection.enabled: true
说明：添加这个配置以后在kibana中才会显示联机状态，否则会显示脱机状态

1.10.重启容器

docker restart es

1.11.`Elasticsearch`.`8X`以上默认开启了`X-Pack`安全功能

说明：请求Elasticsearch必须使用https

测试：https://127.0.0.1:9200/

1.12.如果账户密码忘了，设置修改账号密码如下：

docker exec -it es /bin/bash

cd /usr/share/elasticsearch/bin
./elasticsearch-setup-passwords interactive

ElasticSearch设置后账户：elastic，密码：123456

2.部署`kibana`

kibana可以给我们提供一个ElasticSearch的可视化界面，便于我们使用。

2.1.拉取镜像

docker pull kibana:8.8.1

2.2.第一次执行`docker`启动脚本

docker run -it \
 -d \
 --restart=always \
 --log-driver json-file \
 --log-opt max-size=100m \
 --log-opt max-file=2 \
 --name kibana \
 -p 5601:5601 \
 --net es-net \
kibana:8.8.1

2.3.创建`kibana`挂载目录

mkdir -p ~/data/kibana

2.4.给创建的文件夹授权

sudo chown -R 1000:1000 ~/data/kibana

2.5.将容器内的文件复制到主机上

docker cp kibana:/usr/share/kibana/config ~/data/kibana
docker cp kibana:/usr/share/kibana/data ~/data/kibana
docker cp kibana:/usr/share/kibana/plugins ~/data/kibana
docker cp kibana:/usr/share/kibana/logs ~/data/kibana

2.6.删除容器

docker rm -f kibana

2.7.修改配置文件`/home/elk8.6.2/kibana/config/kibana.yml`:

增加：i18n.locale: “zh-CN”
修改：elasticsearch.hosts: [‘https://172.20.0.2:9200’]，将IP改成elasticsearch的docker ip，注意一定要用https
增加，不验证ssl：elasticsearch.ssl.verificationMode: none
设置用户名密码：lasticsearch.username: "kibana_system"、elasticsearch.password: "123456"

2.8.修改`docker`启动脚本，增加挂载目录

docker run -it \
 -d \
 -e ELASTICSEARCH_HOSTS=https://es:9200 \
 -p 5601:5601 \
 --restart=always \
 --log-driver json-file \
 --log-opt max-size=100m \
 --log-opt max-file=2 \
 --name kibana \
 --net es-net \
 -v ~/data/kibana/config:/usr/share/kibana/config \
 -v ~/data/kibana/data:/usr/share/kibana/data \
 -v ~/data/kibana/plugins:/usr/share/kibana/plugins \
 -v ~/data/kibana/logs:/usr/share/kibana/logs \
kibana:8.8.1

2.9.查看`kibana`日志

docker logs -f kibana

此时，在浏览器输入地址访问：http://127.0.0.1:5601，即可看到结果。

账号密码是kibana.yml中配置的用户名密码

2.10.DevTools

kibana中提供了一个DevTools界面：

这个界面中可以编写DSL来操作elasticsearch。并且对DSL语句有自动补全功能。

4.部署`es`集群

署es集群可以直接使用docker-compose来完成，不过要求你的Linux虚拟机至少有4G的内存空间

首先编写一个docker-compose文件，内容如下：

version: '2.2'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.6.2
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es02,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data01:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - elastic
  es02:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.6.2
    container_name: es02
    environment:
      - node.name=es02
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es01,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data02:/usr/share/elasticsearch/data
    networks:
      - elastic
  es03:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.6.2
    container_name: es03
    environment:
      - node.name=es03
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es01,es02
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data03:/usr/share/elasticsearch/data
    networks:
      - elastic

volumes:
  data01:
    driver: local
  data02:
    driver: local
  data03:
    driver: local

networks:
  elastic:
    driver: bridge

运行docker-compose以启动集群：

docker-compose up

遇到的问题：

1、es 登陆时需要用https

2、es 账号密码需要重置，

设置账号密码
docker exec -it es /bin/bash
cd /usr/share/elasticsearch/bin
./elasticsearch-setup-passwords interactive

4、kibana 启动报错：

参考文档：https://blog.csdn.net/yangkei/article/details/126837326

[2022-09-06T19:47:01.491-04:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. security_exception: [security_exception] 
Reason: unable to authenticate user [kibana_system] for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip]

1. kibana启动报错，kibana_system用户认证

[2022-09-06T19:47:01.491-04:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. security_exception: [security_exception] Reason: unable to authenticate user [kibana_system] for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip]

解决办法：设置kibana_system用户的密码。
[es@goya1 cert]$ elasticsearch-reset-password -u kibana_system -i
warning: ignoring JAVA_HOME=/app/elasticsearch/jdk; using bundled JDK
This tool will reset the password of the [kibana_system] user.
You will be prompted to enter the password.
Please confirm that you would like to continue [y/N]y
Enter password for [kibana_system]: changeit123
Re-enter password for [kibana_system]: changeit123
Password for the [kibana_system] user successfully reset.

修改,确认kibana.yml文件的配置部分：
# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana
# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
# is proxied through the Kibana server.
elasticsearch.username: "kibana_system"
elasticsearch.password: "changeit123"
