docker安装Elasticsearch7.6集群并设置密码

这篇文章主要介绍了docker安装Elasticsearch7.6集群并设置密码，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

Elasticsearch从6.8开始， 允许免费用户使用X-Pack的安全功能， 以前安装es都是裸奔。接下来记录配置安全认证的方法。

为了简化物理安装过程，我们将使用docker安装我们的服务。

一些基础配置

es需要修改linux的一些参数。

设置vm.max_map_count=262144

1
2
sudo vim /etc/sysctl.conf
vm.max_map_count=262144

不重启， 直接生效当前的命令

1
sysctl -w vm.max_map_count=262144

es的data和logs目录需要给1000的用户授权， 我们假设安装3个实力的es集群，先创建对应的数据存储文件

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的用户id为1000，这里暂且授权给所有人好了
sudo chmod 777 es* -R

关于版本和docker镜像

Elasticsearch分几种licenses，其中Open Source和Basic是免费的， 而在6.8之后安全功能才开始集成在es的Basic授权上。

Basic对应docker镜像为

1
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.6.2

同时dockerhub同步为elasticsearch. 我们直接拉取elasticsearch:7.6.2就好。

开始

安装文件均放在GitHub： https://github.com/Ryan-Miao/docker-china-source/tree/master/docker-elasticsearch

首先，创建docker-compose.yml

关于elasticsearch.yml

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 设置允许其他ip访问，解除ip绑定

  • xpack.security 则是安全相关配置，其中ssl的证书需要自己生成

关于证书elastic-certificates.p12

es提供了生成证书的工具elasticsearch-certutil，我们可以在docker实例中生成它，然后复制出来，后面统一使用。

首先运行es实例

1
sudo docker run -dit --name=es elasticsearch:7.6.2 /bin/bash

进入实例内部

1
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.

这个生成elastic-certificates.p12 就是我们需要使用的。

复制出证书, ctrl+d退出容器内部

1

4
sudo docker cp es:/usr/share/elasticsearch/elastic-certificates.p12 .
# 关闭这个容器
sudo docker kill es
sudo docker rm es

如此获取了证书。

生成密码

我们首先要启动es集群，去里面生成密码。

1
sudo docker-compose up

然后进入其中一台

1
sudo docker exec -it es01 /bin/bash

生成密码用auto， 自己设置用 interactive

auto - Uses randomly generated passwords
interactive - Uses passwords entered by a user
 
Non-option arguments:

-E <KeyValuePair> Configure a setting
-h, --help     Show help    
-s, --silent    Show minimal 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

使用密码

浏览器访问localhost:9200/9201/9202 需要输入账号

输入对应的elastic/password就好

浏览器访问localhost:5601

忘记密码

如果生成后忘记密码了怎么办， 可以进入机器去修改。

进入es的机器

1
sudo docker exec -it es01 /bin/bash

创建一个临时的超级用户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:

用这个用户去修改elastic的密码：

curl -XPUT -u ryan:ryan123 http://localhost:9200/_xpack/security/user/elastic/_password -H "Content-Type: application/json" -d '

 "password": "q5f2qNfUJQyvZPIz57MZ"
}'
