docker安裝elastic search和kibana的實現

2022-04-11 10:00:26

安裝目標

使用docker安裝elastic search和kibana，版本均為7.17.1

安裝es

1. docker pull

去dockerhub看具體版本，這裡用7.17.1

docker pull elasticsearch:7.17.1
docker pull kibana:7.17.1

2. 臨時安裝生成檔案

 docker run -d --name elasticsearch  -p 9200:9200 -p 9300:9300 -e  "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms256m -Xmx256m" elasticsearch:7.17.1

引數說明

-d 後臺啟動
–name 起別名即：NAMES
-p 9200:9200 將埠對映出來
elasticsearch的9200埠是供外部存取使用；9300埠是供內部存取使用叢集間通訊
-e "discovery.type=single-node"單節點啟動
-e ES_JAVA_OPTS="-Xms256m -Xmx256m" 限制記憶體大小

確保成功啟動

docker ps

3. 設定外部資料卷

執行

mkdir -p /data/elasticsearch/{config,data,logs,plugins}
yml

將容器內檔案拷貝出來

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

設定elasticsearch.yml的內容

vi /data/elasticsearch/config/elasticsearch.yml

確保有以下幾個設定，原有的設定可以不改動

cluster.name: "docker-cluster"
network.hosts:0.0.0.0
# 跨域
http.cors.allow-origin: "*"
http.cors.enabled: true
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

4. 停止並刪除臨時容器

docker stop elasticsearch
docker rm elasticsearch

5. 重新起容器並掛載外部資料夾

docker run -d --name elasticsearch 
-p 9200:9200 
-p 9300:9300 
-e "discovery.type=single-node" 
-e ES_JAVA_OPTS="-Xms256m -Xmx256m" 
-v /data/elasticsearch/logs:/usr/share/elasticsearch/logs 
-v /data/elasticsearch/data:/usr/share/elasticsearch/data 
-v /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins 
-v /data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
elasticsearch:7.17.1

等docker容器起來一分鐘左右，再存取9200 埠，會返回

因為安裝的是V7版本的，預設沒開啟x-pack(v8預設開啟)，所以能直接存取

[root@iZuf6ai62xce7wexx4wwi9Z config]# curl "http://localhost:9200"
{
  "name" : "6a1036c69d59",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "0zgLiGhESGKQYTYy9gH4iA",
  "version" : {
    "number" : "7.17.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "e5acb99f822233d62d6444ce45a4543dc1c8059a",
    "build_date" : "2022-02-23T22:20:54.153567231Z",
    "build_snapshot" : false,
    "lucene_version" : "8.11.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
[root@iZuf6ai62xce7wexx4wwi9Z config]#

安裝kibana

1. 執行臨時容器

docker run -d --name kibana -p 5601:5601 kibana:7.17.1

2. 建立本地掛載檔案

mkdir -p /data/kibana/config
docker cp kibana:/usr/share/kibana/config /data/kibana/

在本地就能看到拷貝出來的kibana.yml檔案，

vim /data/kibana/config/kibana.yml

修改設定為

#
# ** THIS IS AN AUTO-GENERATED FILE **
#

# Default Kibana configuration for docker target
server.host: "0"
server.shutdownTimeout: "5s"
elasticsearch.hosts: [ "http://localhost:9100" ] # 記得修改ip
monitoring.ui.container.elasticsearch.enabled: true
i18n.locale: "zh-CN"

3. 停掉臨時容器並重新啟動

停掉舊的

docker stop kibana
docker rm kibana

重新啟動掛載了地址的新的容器

docker run -d --name kibana -p 5601:5601 -v /data/kibana/config:/usr/share/kibana/config kibana:7.17.1

4. 進入elasticsearch容器獲取token#

存取kibana發現需要token

進入es容器獲取token

docker exec -it {elastic_search_container_id} /bin/bash
bin/elasticsearch-create-enrollment-token --scope kibana

拷貝token到kibana的ui上輸入

5. 進入kibana容器獲取驗證碼#

進入kibana容器獲取token

docker exec -it kibana /bin/bash

# 執行生成驗證碼命令
bin/kibana-verification-code

6. 重置elastic密碼

進入es容器

docker exec -it {elastic_search_container_id} /bin/bash
bin/elasticsearch-reset-password --username elastic -i

後面就使用elastic賬戶和密碼登入kibana

為es和kibana設定密碼

es開啟x-pack

vim /data/elasticsearch/config/elasticsearch.yml

增加以下xpack.security.enabled

cluster.name: "docker-cluster-01"
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

# 此處開啟xpack
xpack.security.enabled: true

重啟es容器

docker restart elasticsearch

進入es容器修改密碼

docker exec -ti elasticsearch /bin/bash
/usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive

然後會分別讓重置以下的密碼，這裡重置成123456

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]:
passwords must be at least [6] characters long
Try again.
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]

重置完畢之後帶上使用者就可以存取了

[root@k8s-master ~]# curl localhost:9200 -u elastic
Enter host password for user 'elastic':
{
  "name" : "cd52e7fbacd1",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "0S-V9zElSie_zXtcDRssAQ",
  "version" : {
    "number" : "8.1.2",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "31df9689e80bad366ac20176aa7f2371ea5eb4c1",
    "build_date" : "2022-03-29T21:18:59.991429448Z",
    "build_snapshot" : false,
    "lucene_version" : "9.0.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}
[root@k8s-master ~]#

修改kibana的密碼

修改組態檔

vi /data/kibana/config/kibana.yml

#
# ** THIS IS AN AUTO-GENERATED FILE **
#

# Default Kibana configuration for docker target
server.host: "0"
server.shutdownTimeout: "5s"
elasticsearch.hosts: [ "http://172.17.0.3:9200" ]
monitoring.ui.container.elasticsearch.enabled: true
i18n.locale: "zh-CN"
# 此處設定elastic的使用者名稱和密碼
elasticsearch.username: elastic
elasticsearch.password: "123456"

重啟容器

docker restart kibana

安裝elastic-head

docker run -d 
--name=elasticsearch-head 
-p 9100:9100 
mobz/elasticsearch-head:5-alpine

連線叢集不能連localhost:9200，而是

http://{ip}:9200/

後續帶x-pack的認證資訊的存取

url上帶上使用者名稱密碼

http://{ip}:9100/?auth_user=elastic&auth_password=123456
