• TencentOS Server 3.1
• Docker version 19.03.14, build 5eb3275d40
• elasticsearch: 7.10.0

安裝ElasticSearch/ES

安裝步驟1：準(zhǔn)備

1. 安裝docker

安裝 docker 參考：【Centos 8】【Centos 7】安裝 docker

2. 搜索可以使用的鏡像。

```
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. 也可從docker hub上搜索鏡像。

docker hub，docker hub-stage。

4. 選擇合適的redis鏡像。

安裝步驟2：拉取ElasticSearch鏡像

1 拉取鏡像

shell> docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0

2 查看已拉取的鏡像

shell> docker images
REPOSITORY                                      TAG       IMAGE ID       CREATED         SIZE
docker.elastic.co/elasticsearch/elasticsearch   7.10.0    37190fe5beea   2 years ago     774MB
mobz/elasticsearch-head                         5         b19a5c98e43b   6 years ago     824MB

安裝步驟3：創(chuàng)建容器

創(chuàng)建容器方式1：快速創(chuàng)建容器

shell> docker create -e "discovery.type=single-node" -p 9200:9200  -p 9300:9300 \
-e ES_JAVA_OPTS="-Xms1g -Xmx1g" \
--name elasticsearch1 docker.elastic.co/elasticsearch/elasticsearch:7.10.0

• --ulimit nofile=65536:65536
• --privileged=true

安裝步驟4：運行容器

shell> docker start elasticsearch1

安裝步驟5：檢查是否安裝成功

瀏覽器訪問http://localhost:9200, 如果出現(xiàn)以下界面就是安裝成功：

ElasticSearch 配置

工作目錄/WorkingDir

"WorkingDir": "/usr/share/elasticsearch" 

設(shè)置跨域請求

shell> docker exec -it elasticsearch1 /bin/bash
shell> vi /usr/share/elasticsearch/config/elasticsearch.yml

增加如下配置：

http.cors:
  enabled: true
  allow-origin: "*"

設(shè)置 JVM 內(nèi)存參數(shù)

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

設(shè)置密碼

啟用密碼訪問

shell> docker exec -it elasticsearch1 bash
shell> vi /usr/share/elasticsearch/config/elasticsearch.yml

修改配置：

http.cors:
  enabled: true
  allow-origin: "*"
  allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

設(shè)置6個賬戶密碼

shell> docker exec -it elasticsearch1 /bin/bash
shell> cd /usr/share/elasticsearch/bin
shell> elasticsearch-setup-passwords interactive
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.
You will be prompted to enter passwords as the process progresses.
Please confirm that you would like to continue [y/N]y


Enter password for [elastic]: 
Reenter password for [elastic]: 
Enter password for [apm_system]: 
Reenter password for [apm_system]: 
Enter password for [kibana_system]: 
Reenter password for [kibana_system]: 
Enter password for [logstash_system]: 
Reenter password for [logstash_system]: 
Enter password for [beats_system]: 
Reenter password for [beats_system]: 
Enter password for [remote_monitoring_user]: 
Reenter password for [remote_monitoring_user]: 
Changed password for user [apm_system]
Changed password for user [kibana_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]

容器設(shè)置

容器隨 docker 自動啟動

設(shè)置容器的重啟策略

shell> docker update --restart=always elasticsearch1

• 每次docker啟動時，容器也會自動啟動

容器設(shè)置IP

向網(wǎng)絡(luò)中添加容器

shell> docker network connect --ip 172.19.0.2  mynetwork elasticsearch1 

• docket ip : 172.19.0.2

安裝elasticsearch-head

Docker安裝 elasticsearch-head
