elasticsearch 安全

一、集群身份认证与用户鉴权

1，开启es安全模块

#启动单节点
bin/elasticsearch -E node.name=node0 -E cluster.name=geektime -E path.data=node0_data -E http.port=9200 -E xpack.security.enabled=true
或者
bin/elasticsearch -E xpack.security.enabled=true


#使用Curl访问ES，或者浏览器访问 “localhost:9200/_cat/nodes?pretty”。返回401错误
curl 'localhost:9200/_cat/nodes?pretty'

#运行密码设定的命令，设置ES内置用户及其初始密码。
bin/elasticsearch-setup-passwords interactive

curl -u elastic 'localhost:9200/_cat/nodes?pretty'

2，设置kibana

# 修改 kibana.yml
elasticsearch.username: "kibana"
elasticsearch.password: "changeme"

3，登录

#启动。使用用户名，elastic，密码a123456

二、集群内安全通信

# 生成证书
# 为您的Elasticearch集群创建一个证书颁发机构。例如，使用elasticsearch-certutil ca命令：
bin/elasticsearch-certutil ca

#为群集中的每个节点生成证书和私钥。例如，使用elasticsearch-certutil cert 命令：
bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12

#将证书拷贝到 config/certs目录下
elastic-certificates.p12


bin/elasticsearch -E node.name=node0 -E cluster.name=geektime -E path.data=node0_data -E http.port=9200 -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.security.transport.ssl.verification_mode=certificate -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12

bin/elasticsearch -E node.name=node1 -E cluster.name=geektime -E path.data=node1_data -E http.port=9201 -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.security.transport.ssl.verification_mode=certificate -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.truststore.path=certs/elastic-certificates.p12


#不提供证书的节点，无法加入
bin/elasticsearch -E node.name=node2 -E cluster.name=geektime -E path.data=node2_data -E http.port=9202 -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.security.transport.ssl.verification_mode=certificate

## elasticsearch.yml 配置

#xpack.security.transport.ssl.enabled: true
#xpack.security.transport.ssl.verification_mode: certificate

#xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12
#xpack.security.transport.ssl.truststore.path: certs/elastic-certificates.p12

三、使用https与集群外部间的安全通信

xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: certs/elastic-certificates.p12
xpack.security.http.ssl.truststore.path: certs/elastic-certificates.p12

# ES 启用 https
bin/elasticsearch -E node.name=node0 -E cluster.name=geektime -E path.data=node0_data -E http.port=9200 -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.security.transport.ssl.verification_mode=certificate -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.http.ssl.enabled=true -E xpack.security.http.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.http.ssl.truststore.path=certs/elastic-certificates.p12

#Kibana 连接 ES https



# 为kibana生成pem
openssl pkcs12 -in elastic-certificates.p12 -cacerts -nokeys -out elastic-ca.pem


elasticsearch.hosts: ["https://localhost:9200"]
elasticsearch.ssl.certificateAuthorities: [ "/Users/yiruan/geektime/kibana-7.1.0/config/certs/elastic-ca.pem" ]
elasticsearch.ssl.verificationMode: certificate



# 为 Kibna 配置 HTTPS
# 生成后解压，包含了instance.crt 和 instance.key
bin/elasticsearch-certutil ca --pem

server.ssl.enabled: true
server.ssl.certificate: config/certs/instance.crt
server.ssl.key: config/certs/instance.key
