elasticsearch從6.8開始， 允許免費用戶使用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。
一些基礎配置
es需要修改linux的一些參數。
設置vm.max_map_count=262144
|
1
2
|
sudo vim /etc/sysctl.confvm.max_map_count=262144 |
不重啟， 直接生效當前的命令
|
1
|
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/datamkdir -p es01/logsmkdir -p es02/datamkdir -p es02/logsmkdir -p es03/datamkdir -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
|
1
|
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

關于elasticsearch.yml

- 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
|
1
|
sudo docker run -dit --name=es elasticsearch:7.6.2 /bin/bash |
進入實例內部
|
1
|
sudo docker exec -it es /bin/bash |
生成ca: elastic-stack-ca.p12

[root@25dee1848942 elasticsearch]# ./bin/elasticsearch-certutil cathis tool assists you in the generation of x.509 certificates and certificatesigning 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 usedto sign certificate when running in 'cert' mode.use the 'ca-dn' option if you wish to configure the 'distinguished name'of the certificate authorityby default the 'ca' mode produces a single pkcs#12 output file which holds: * the ca certificate * the ca's private keyif you elect to generate pem format certificates (the -pem option), then the output willbe a zip file containing individual files for the ca certificate and private keyplease enter the desired output file [elastic-stack-ca.p12]: enter password for elastic-stack-ca.p12 : |
再生成cert: elastic-certificates.p12

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 essudo 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。
|
1
|
sudo docker-compose up |
然后進入其中一臺
|
1
|
sudo docker exec -it es01 /bin/bash |
生成密碼用auto， 自己設置用 interactive

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
|
1
|
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 superuserenter new password: error: invalid password...passwords must be at least [6] characters long[root@cfeeab4bb0eb elasticsearch]# ./bin/elasticsearch-users useradd ryan -r superuserenter 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"}' |
