CentOS7 Docker安装 ElasticSearch8、Kibana8

一、Docker安装

yum install -y docker

#开机自启
systemctl enable docker
#启动 docker
systemctl start docker

二、安装 ElasticSearch

docker pull docker.elastic.co/elasticsearch/elasticsearch:8.6.2

vi /etc/sysctl.conf
在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144

docker network create elastic
docker run --name es01 --net elastic -p 9200:9200 -it docker.elastic.co/elasticsearch/elasticsearch:8.6.2

#运行成功后，会出现：
✅ Elasticsearch security features have been automatically configured!
✅ Authentication is enabled and cluster connections are encrypted.

ℹ️  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  fahCf24pIcF6ytXOY95=

ℹ️  HTTP CA certificate SHA-256 fingerprint:
  860a07d87cd669c5e83fd1228c8dbdc35afe40802f80661d7990770bf93e58b1

ℹ️  Configure Kibana to use this cluster:
• Run Kibana and click the configuration link in the terminal when Kibana starts.
• Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

ℹ️ Configure other nodes to join this cluster:
• Copy the following enrollment token and start new Elasticsearch nodes with `bin/elasticsearch --enrollment-token <token>` (valid for the next 30 minutes):
  eyJ2ZXIiOiI4LjYuMiIsImFkciI6WyIxNzIuMTguMC4yOjkyMDAiXSwiZmdyIjoiODYwYTA3ZDg3Y2Q2NjljNWU4M2ZkMTIyOGM4ZGJkYzM1YWZlNDA4MDJmODA2NjFkNzk5MDc3MGJmOTNlNThiMSIsImtleSI6Ii0wMy1NWWNCZUxJWDZldDJ0MmsyOlF1TVktVWhVVHE2T1lhcFZLSnZ2SFEifQ==

  If you're running in Docker, copy the enrollment token and run:
  `docker run -e "ENROLLMENT_TOKEN=<token>" docker.elastic.co/elasticsearch/elasticsearch:8.6.2`

三、安装 Kibana

docker pull docker.elastic.co/kibana/kibana:8.6.2
docker run --name kib01 --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.6.2

#运行成功后，会让你访问：
Go to http://0.0.0.0:5601/?code=989981 to get started.
0.0.0.0 替换成你服务器的地址
然后将上一步生成的的Kibana token 输入，最后输入用户名elastic,生成的密码，即可访问

四、其他配置

#如果想要自定义 ElasticSearch 密码：
docker exec -it es01 /bin/bash
elasticsearch-reset-password -u elastic -i

五、如果你要访问ES，需要使用 https 协议

如果你直接用地址比如：110.212.33.123:9200，是没法访问的，需要带上 https://110.212.33.123:9200。

六、记得安全组开放端口、防火墙开放端口
