elk docker part 1 of 3 elasticsearch8

elk: elasticsearch+kibana+logstash

自从elk升级8.0以后，强制使用上了SSL(可以关闭)，踩了不少的坑，花了不少时间折腾。

使用的版本8.0.0

共3个部分，这是第1部分,elasticsearch8

---

1. 安装docker

2. 安装elastic

docker pull elasticsearch:8.0.0

3. 运行elastic, 不加载目录

#8.0 above, require password
docker run -p9200:9200 -p9300:9300 -e node.name=node-1 -d –name elasticsearch elasticsearch:8.0.0
运行后，复制目录到宿主机

#docker cp 0000:/usr/share/elasticsearch /mnt/md0/appdata/mydocker

0000是container_id, /mnt/md0/appdata/mydocker是本地目录，这两个地方换成自己的

完成后，停止容器

docker stop 0000

删除容器

docker rm 0000

4.运行正式的elastic

docker run -p9200:9200 -p9300:9300 -v /mnt/md0/appdata/mydocker/elasticsearch/config:/usr/share/elasticsearch/config -v /mnt/md0/appdata/mydocker/elasticsearch/data:/usr/share/elasticsearch/data -v /mnt/md0/appdata/mydocker/elasticsearch/logs:/usr/share/elasticsearch/logs -v /mnt/md0/appdata/mydocker/elasticsearch/plugins:/usr/share/elasticsearch/plugins -e TZ=Asia/Shanghai -e node.name=node-1 -d –name elasticsearch elasticsearch:8.0.0

5.进入elastic的主目录，修改连接的密码

#docker exec -it 0000 bash

$cd /usr/share/elasticsearch

$./bin/elasticsearch-setup-passwords interactive

提示输入密码和确认密码，全部都设成 111111 (最少6位)

6.完成后验证

浏览器访问：https://宿主机IP:9200

录入用户名：elastic 密码111111

7.附上elasticsearch.yml

cluster.name: “docker-cluster”
network.host: 0.0.0.0
