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
sudo vim /etc/sysctl.conf vm.max_map_count=262144
不重启， 直接生效当前的命令
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
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。
首先，创建docker-compose.yml
version: '2.2'
services:
es01:
image: elasticsearch:7.6.2
container_name: es01
environment:
- node.name=es01

关于elasticsearch.yml
内容如下
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 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
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
sudo docker run -dit --name=es elasticsearch:7.6.2 /bin/bash
进入实例内部
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.
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
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。
sudo docker-compose up
然后进入其中一台
sudo docker exec -it es01 /bin/bash
生成密码用auto， 自己设置用 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
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"
}'
