本文小編為大家詳細介紹“docker怎么安裝Elasticsearch集群并設置密碼”,內容詳細,步驟清晰,細節處理妥當,希望這篇“docker怎么安裝Elasticsearch集群并設置密碼”文章能幫助大家解決疑惑,下面跟著小編的思路慢慢深入,一起來學習新知識吧。
一些基礎配置
es需要修改linux的一些參數。
設置vm.max_map_count=262144
sudo vim /etc/sysctl.conf vm.max_map_count=262144
不重啟, 直接生效當前的命令
sysctl -w vm.max_map_count=262144
es的data和logs目錄需要給1000的用戶授權, 我們假設安裝3個實力的es集群,先創建對應的數據存儲文件
mkdir -p es01/data mkdir -p es01/logs mkdir -p es02/data mkdir -p es02/logs mkdir -p es03/data mkdir -p es03/logs ## es的用戶id為1000,這里暫且授權給所有人好了 sudo chmod 777 es* -r
關于版本和docker鏡像
elasticsearch分幾種licenses,其中open source和basic是免費的, 而在6.8之后安全功能才開始集成在es的basic授權上。
basic對應docker鏡像為
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.6.2
同時dockerhub同步為elasticsearch. 我們直接拉取elasticsearch:7.6.2
就好。
開始
安裝文件均放在github: https://github.com/ryan-miao/docker-china-source/tree/master/docker-elasticsearch
首先,創建docker-compose.yml
version: '2.2' services: es01: image: elasticsearch:7.6.2 container_name: es01 environment: - node.name=es01 - cluster.name=es-docker-cluster - discovery.seed_hosts=es02,es03 - cluster.initial_master_nodes=es01,es02,es03 - bootstrap.memory_lock=true - "es_java_opts=-xms512m -xmx512m" ulimits: memlock: soft: -1 hard: -1 volumes: - ./es01/data:/usr/share/elasticsearch/data - ./es01/logs:/usr/share/elasticsearch/logs - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml - ./elastic-certificates.p12:/usr/share/elasticsearch/config/elastic-certificates.p12 ports: - 9200:9200 networks: - elastic es02: image: elasticsearch:7.6.2 container_name: es02 environment: - node.name=es02 - cluster.name=es-docker-cluster - discovery.seed_hosts=es01,es03 - cluster.initial_master_nodes=es01,es02,es03 - bootstrap.memory_lock=true - "es_java_opts=-xms512m -xmx512m" ulimits: memlock: soft: -1 hard: -1 volumes: - ./es02/data:/usr/share/elasticsearch/data - ./es02/logs:/usr/share/elasticsearch/logs - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml - ./elastic-certificates.p12:/usr/share/elasticsearch/config/elastic-certificates.p12 ports: - 9201:9200 networks: - elastic es03: image: elasticsearch:7.6.2 container_name: es03 environment: - node.name=es03 - cluster.name=es-docker-cluster - discovery.seed_hosts=es01,es02 - cluster.initial_master_nodes=es01,es02,es03 - bootstrap.memory_lock=true - "es_java_opts=-xms512m -xmx512m" ulimits: memlock: soft: -1 hard: -1 volumes: - ./es03/data:/usr/share/elasticsearch/data - ./es03/logs:/usr/share/elasticsearch/logs - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml - ./elastic-certificates.p12:/usr/share/elasticsearch/config/elastic-certificates.p12 ports: - 9202:9200 networks: - elastic kib01: depends_on: - es01 image: kibana:7.6.2 container_name: kib01 ports: - 5601:5601 environment: elasticsearch_url: http://es01:9200 elasticsearch_hosts: http://es01:9200 volumes: - ./kibana.yml:/usr/share/kibana/config/kibana.yml networks: - elastic networks: elastic: driver: bridge
關于elasticsearch.yml
內容如下
network.host: 0.0.0.0 xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.keystore.type: pkcs12 xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.keystore.path: elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: elastic-certificates.p12 xpack.security.transport.ssl.truststore.type: pkcs12 xpack.security.audit.enabled: true
network.host 設置允許其他ip訪問,解除ip綁定
xpack.security 則是安全相關配置,其中ssl的證書需要自己生成
關于證書elastic-certificates.p12
es提供了生成證書的工具elasticsearch-certutil
,我們可以在docker實例中生成它,然后復制出來,后面統一使用。
首先運行es實例
sudo docker run -dit --name=es elasticsearch:7.6.2 /bin/bash
進入實例內部
sudo docker exec -it es /bin/bash
生成ca: elastic-stack-ca.p12
[root@25dee1848942 elasticsearch]# ./bin/elasticsearch-certutil ca this tool assists you in the generation of x.509 certificates and certificate signing requests for use with ssl/tls in the elastic stack. the 'ca' mode generates a new 'certificate authority' this will create a new x.509 certificate and private key that can be used to sign certificate when running in 'cert' mode. use the 'ca-dn' option if you wish to configure the 'distinguished name' of the certificate authority by default the 'ca' mode produces a single pkcs#12 output file which holds: * the ca certificate * the ca's private key if you elect to generate pem format certificates (the -pem option), then the output will be a zip file containing individual files for the ca certificate and private key please enter the desired output file [elastic-stack-ca.p12]: enter password for elastic-stack-ca.p12 :
再生成cert: elastic-certificates.p12
[root@25dee1848942 elasticsearch]# ./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12 this tool assists you in the generation of x.509 certificates and certificate signing requests for use with ssl/tls in the elastic stack. the 'cert' mode generates x.509 certificate and private keys.
這個生成elastic-certificates.p12 就是我們需要使用的。
復制出證書, ctrl+d退出容器內部
sudo docker cp es:/usr/share/elasticsearch/elastic-certificates.p12 . # 關閉這個容器 sudo docker kill es sudo docker rm es
如此獲取了證書。
生成密碼
我們首先要啟動es集群,去里面生成密碼。
sudo docker-compose up
然后進入其中一臺
sudo docker exec -it es01 /bin/bash
生成密碼用auto, 自己設置用 interactive
[root@cfeeab4bb0eb elasticsearch]# ./bin/elasticsearch-setup-passwords -h sets the passwords for reserved users commands -------- auto - uses randomly generated passwords interactive - uses passwords entered by a user non-option arguments: command option description ------ ----------- -e <keyvaluepair> configure a setting -h, --help show help -s, --silent show minimal output -v, --verbose show verbose output [root@cfeeab4bb0eb elasticsearch]# ./bin/elasticsearch-setup-passwords auto initiating the setup of passwords for reserved users elastic,apm_system,kibana,logstash_system,beats_system,remote_monitoring_user. the passwords will be randomly generated and printed to the console. please confirm that you would like to continue [y/n]y changed password for user apm_system password apm_system = yxvzet9b2jedujyp66ws changed password for user kibana password kibana = 8nnthbj0n02idatghidu changed password for user logstash_system password logstash_system = 9nidge7ksv8sqidsk8dj changed password for user beats_system password beats_system = qeuvaf1vealpjhfeuojj changed password for user remote_monitoring_user password remote_monitoring_user = dtzcrckvtzsinrn3tw3d changed password for user elastic password elastic = q5f2qnfujqyvzpiz57mz
使用密碼
瀏覽器訪問localhost:9200/9201/9202 需要輸入賬號
輸入對應的elastic/password就好
瀏覽器訪問localhost:5601
忘記密碼
如果生成后忘記密碼了怎么辦, 可以進入機器去修改。
進入es的機器
sudo docker exec -it es01 /bin/bash
創建一個臨時的超級用戶ryanmiao
./bin/elasticsearch-users useradd ryan -r superuser enter new password: error: invalid password...passwords must be at least [6] characters long [root@cfeeab4bb0eb elasticsearch]# ./bin/elasticsearch-users useradd ryan -r superuser enter new password: retype new password:
用這個用戶去修改elastic的密碼:
curl -xput -u ryan:ryan123 http://localhost:9200/_xpack/security/user/elastic/_password -h "content-type: application/json" -d ' { "password": "q5f2qnfujqyvzpiz57mz" }'
