docker安裝Elasticsearch7.6集群并設(shè)置密碼的方法步驟
Elasticsearch從6.8開始, 允許免費(fèi)用戶使用X-Pack的安全功能, 以前安裝es都是裸奔。接下來記錄配置安全認(rèn)證的方法。
為了簡化物理安裝過程,我們將使用docker安裝我們的服務(wù)。
一些基礎(chǔ)配置
es需要修改linux的一些參數(shù)。
設(shè)置vm.max_map_count=262144
sudo vim /etc/sysctl.conf vm.max_map_count=262144
不重啟, 直接生效當(dāng)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(quán), 我們假設(shè)安裝3個(gè)實(shí)力的es集群,先創(chuàng)建對(duì)應(yīng)的數(shù)據(jù)存儲(chǔ)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(quán)給所有人好了 sudo chmod 777 es* -R
關(guān)于版本和docker鏡像
Elasticsearch分幾種licenses,其中Open Source和Basic是免費(fèi)的, 而在6.8之后安全功能才開始集成在es的Basic授權(quán)上。
Basic對(duì)應(yīng)docker鏡像為
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.6.2
同時(shí)dockerhub同步為elasticsearch. 我們直接拉取elasticsearch:7.6.2
就好。
開始
首先,創(chuàng)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(guān)于elasticsearch.yml
內(nèi)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(shè)置允許其他ip訪問,解除ip綁定
- xpack.security 則是安全相關(guān)配置,其中ssl的證書需要自己生成
關(guān)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(shí)例中生成它,然后復(fù)制出來,后面統(tǒng)一使用。
首先運(yùn)行es實(shí)例
sudo docker run -dit --name=es elasticsearch:7.6.2 /bin/bash
進(jìn)入實(shí)例內(nèi)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(gè)生成elastic-certificates.p12 就是我們需要使用的。
復(fù)制出證書, ctrl+d退出容器內(nèi)部
sudo docker cp es:/usr/share/elasticsearch/elastic-certificates.p12 . # 關(guān)閉這個(gè)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(dòng)es集群,去里面生成密碼。
sudo docker-compose up
然后進(jìn)入其中一臺(tái)
sudo docker exec -it es01 /bin/bash
生成密碼用auto, 自己設(shè)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(hào)
輸入對(duì)應(yīng)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(jìn)入機(jī)器去修改。
進(jìn)入es的機(jī)器
sudo docker exec -it es01 /bin/bash
創(chuàng)建一個(gè)臨時(shí)的超級(jí)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(gè)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" }'
