安装ElasticSearch/ES
安装步骤1：准备
1. 安装docker
安装 docker 参考：【Centos 8】【Centos 7】安装 docker
2. 搜索可以使用的镜像。
shell> docker search elasticsearch
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
elasticsearch Elasticsearch is a powerful open source sear… 6115 [OK]
kibana Kibana gives shape to any kind of data — str… 2622 [OK]
3. 也可从docker hub上搜索镜像。
docker hub，docker hub-stage。
4. 选择合适的redis镜像。
查找镜像。
| 版本 | 拉取命令 |
|---|---|
| 最新版本 | docker pull elasticsearch:latest |
| 7.4.0 | docker pull elasticsearch:7.4.0 |
| 7.12.0 | docker pull elasticsearch:7.12.0 |
| 8.0.0 | docker pull elasticsearch:8.0.0 |
| 8.9.0 | docker pull docker.elastic.co/elasticsearch/elasticsearch:8.9.0 |
安装步骤2：拉取ElasticSearch镜像
1 拉取镜像
shell> docker pull docker.elastic.co/elasticsearch/elasticsearch:8.9.0

Status: Downloaded newer image for docker.elastic.co/elasticsearch/elasticsearch:8.9.0
docker.elastic.co/elasticsearch/elasticsearch:8.9.0
2 查看已拉取的镜像
shell> docker images

安装步骤3：创建容器
创建容器方式1：快速创建容器
shell> docker create -e "discovery.type=single-node" \
--name elasticsearch1 -p 9200:9200 -p 9300:9300 \
docker.elastic.co/elasticsearch/elasticsearch:8.9.0
安装步骤4：运行容器
shell> docker start elasticsearch1
安装步骤5：检查是否安装成功
浏览器访问http://localhost:9200, 如果出现以下界面就是安装成功：
ElasticSearch配置
工作目录/WorkingDir
"WorkingDir": "/usr/share/elasticsearch"
设置跨域请求
shell> docker exec -it elasticsearch1 /bin/bash
shell> vi /usr/share/elasticsearch/config/elasticsearch.yml
增加如下配置：
xpack.security.enabled: false
xpack.security.http.ssl.enabled: false
http.cors:
enabled: true
allow-origin: "*"
重置密码
shell> docker exec -it elasticsearch1 /bin/bash
shell> /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic
WARNING: Owner of file [/usr/share/elasticsearch/config/users] used to be [root], but now is [elasticsearch]
WARNING: Owner of file [/usr/share/elasticsearch/config/users_roles] used to be [root], but now is [elasticsearch]
This tool will reset the password of the [elastic] user to an autogenerated value.
The password will be printed in the console.
Please confirm that you would like to continue [y/N]y
Password for the [elastic] user successfully reset.
New value: bAdUgEN9******
启用用户名密码访问
shell> docker exec -it elasticsearch1 bash
shell> vi /usr/share/elasticsearch/config/elasticsearch.yml
修改配置：
xpack.security.enabled: true
xpack.security.http.ssl.enabled: false
http.cors:
enabled: true
allow-origin: "*"
allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
设置 JVM 内存参数
shell> docker exec -it elasticsearch1 /bin/bash
shell> vi /usr/share/elasticsearch/config/jvm.options
修改如下配置：
################################################################
## IMPORTANT: JVM heap size
################################################################
##
## The heap size is automatically configured by Elasticsearch
## based on the available memory in your system and the roles
## each node is configured to fulfill. If specifying heap is
## required, it should be done through a file in jvm.options.d,
## which should be named with .options suffix, and the min and
## max should be set to the same value. For example, to set the
## heap to 4 GB, create a new file in the jvm.options.d
## directory containing these lines:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/8.9/heap-size.html
## for more information
##
################################################################
-Xms1g
-Xmx1g
容器设置
容器随 docker 自动启动
设置容器的重启策略
shell> docker update --restart=always elasticsearch1
- 每次docker启动时，容器也会自动启动
容器设置IP
向网络中添加容器
shell> docker network connect --ip 172.19.0.2 mynetwork elasticsearch1
- docket ip : 172.19.0.2
安装elasticsearch-head
Docker安装 elasticsearch-head
安装Kibana
略
其它
查看 elasticsearch 的版本
查看容器的版本：
shell> docker ps | grep elasticsearch1
8c23805f805c docker.elastic.co/elasticsearch/elasticsearch:8.9.0 "/bin/tini -- /usr/l…" 9 days ago Up 11 hours 0.0.0.0:9200->9200/tcp, :::9200->9200/tcp, 0.0.0.0:9300->9300/tcp, :::9300->9300/tcp elasticsearch1
登录容器查看版本：文章来源：https://www.toymoban.com/news/detail-652201.html
shell> docker exec -it elasticsearch1 bin/elasticsearch -V
Version: 8.9.0, Build: docker/8aa461beb06aa0417a231c345a1b8c38fb498a0d/2023-07-19T14:43:58.555259655Z, JVM: 20.0.2
把容器中的 ElasticSearch 文件复制出来
shell> docker cp -a elasticsearch1:/usr/share/elasticsearch /data/elasticsearch1/eg
