ElasticSearch
生成相关文件
# 生成 CA
./bin/elasticsearch-certutil ca
# 基于已有 CA 生成压缩包，里面有个elastic-certificates.p12 文件包含节点证书、节点密钥、CA证书
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
修改 config/elasticsearch.yml 文件，添加以下配置
cluster.name: my-cluster
node.name: node-1
xpack.security.transport.ssl.enabled: true
# 如果要使用主机名验证，verification_mode 设置为 full
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.client_authentication: required
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
添加节点证书密码，就是第一步操作h过程中设置的密码
./bin/elasticsearch-keystore add xpack.security.transport.ssl.keystore.secure_password
./bin/elasticsearch-keystore add xpack.security.transport.ssl.truststore.secure_password
到了这里，已经为集群节点之间的通信做了加密处理
生成 https 支持所需文件
./bin/elasticsearch-certutil http
# When asked if you want to generate a CSR, enter n.
# When asked if you want to use an existing CA, enter y.
# Enter the path to your CA. This is the absolute path to the elastic-stack-ca.p12 file that you generated for your cluster.
# Enter the password for your CA.
# Enter an expiration value for your certificate. You can enter the validity period in years, months, or days. For example, enter 90D for 90 days.
# 看要不要预设集群节点来选择 y or n
# When asked if you want to generate one certificate per node, enter y.
# 每个证书都有自己的私钥，并针对特定的主机名或 IP 地址颁发。
# 出现提示时，输入集群中第一个节点的名称。 使用生成节点证书时使用的相同节点名称。
# 输入用于连接到您的第一个节点的所有主机名。 这些主机名将作为 DNS 名称添加到证书的主题备用名称 (SAN) 字段中。
# Each certificate will have its own private key, and will be issued for a specific hostname or IP address.
# When prompted, enter the name of the first node in your cluster. Use the same node name that you used when generating node certificates.
# Enter all hostnames used to connect to your first node. These hostnames will be added as DNS names in the Subject Alternative Name (SAN) field in your certificate.
# 输入所有需要以 https 连接的 ip 或者域名，以换行分隔
# List every hostname and variant used to connect to your cluster over HTTPS.
# 配置客户端可以通过哪些 ip 地址连接到 ES 服务，以换行分隔
# Enter the IP addresses that clients can use to connect to your node.
# Repeat these steps for each additional node in your cluster.
# 执行以上步骤后会得到一个压缩包，将压缩包内的 http.p12 与 elasticsearch-ca.pem 文件分别添加到对应的 ES 或者 Kibana 的 config 文件夹下面，并按照示例 yml 文件进行配置修改
# 如果以上步骤配置了密码，则执行一下脚本添加密码
./bin/elasticsearch-keystore add xpack.security.http.ssl.keystore.secure_password
修改 ES 的 elasticsearch.yml 文件
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: http.p12
修改 Kibana 的 kibana.yml 文件
# 先复制 elasticsearch 配置过程中生成的 elasticsearch-ca.pem 文件到 kibanan 配置文件夹下面，然后添加一下配置，不然的话配置值需要设置为绝对路径值
elasticsearch.ssl.certificateAuthorities: elasticsearch-ca.pem
# 配置 ES https连接地址
elasticsearch.hosts: https://:9200
# 此时，kibana 与 ES 之间的加密通信就配置完成了
Kibana 配置
在上面配置 ES 的时候，就把 kibanna 与 es 之间的加密通信配置好了，此处我们只需要配置 kibana 对外的 https 支持即可
创建证书与key
# 创建证书与key
./bin/elasticsearch-certutil csr -name kibana-server -dns example.com,www.example.com
# 将生成的压缩文件解压得到 kibana-server.crt、kibana-server.key 并复制到 kibana 的配置文件夹下面
修改 kibana.yml 文件
server.ssl.certificate: config/kibana-server.crt
server.ssl.key: config/kibana-server.key
server.ssl.enabled: true
补充
现在 ES 关于密码的设置已经不推荐用户自定义了，建议采用由 ES 提供的 elasticsearch-reset-password 重置密码，使用如下
./bin/elasticsearch-reset-password -u elastic --auto
./bin/elasticsearch-reset-password -u kibana-system --auto
服务启动关闭指令
# 启动 ES
ES_JAVA_OPTS="-Xms2g -Xmx2g" ./bin/elasticsearch -d -p pid
# 关闭 ES
pkill -F pid
# 启动 Kibanan
nohup ./bin/kibana >/dev/null 2>&1 & echo $! > pid
# 关闭 Kibana
pkill -F pid

elasticsearch.yml
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 0.0.0.0
transport.port: 9300
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9201
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.seed_hosts: ["172.17.0.1"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# --------------------------------- Readiness ----------------------------------
#
# Enable an unauthenticated TCP readiness endpoint on localhost
#
readiness.port: 19399
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.client_authentication: required
