elasticsearch 生成enrollment token

在我之前的文章 “如何在 Linux，MacOS 及 Windows 上进行安装 Elasticsearch”，我详细描述了如何在各个平台中安装 Elastic Stack 8.x。在其中的文章中，我们大多采用默认的证书来安装 Elasticsearch。在今天的文章中，我们用自己创建的证书一步一步地来安装 Elastic Stack 8.x。我们可以参考之前的文章：

我们将在 Ubuntu 20.04 上来进行展示。我们将安装最新的 Elastic Stack 8.7.1。

如何使用自定义的证书安装 Elastic Stack 8.x

安装 Elasticsearch

我们首先在 Ubuntu 系统上参照文章 “Elasticsearch: 使用 Debian 安装包来安装 Elasticsearch 8.x” 来安装 Elasticsearch。当然，我们可以使用默认的证书来使得 Elasticsearch 顺利运行，这个是没有任何问题的。但是，在实际的部署中，有很多开发者希望使用自己的证书来进行安装，一方面可控，另一方可以延续之前的 7.x 的安装证书。

在我们运行如下的命令之后：

sudo apt-get update && sudo apt-get install elasticsearch

The generated password for the elastic built-in superuser is : xsYCh*5qOz7hSpkH-fHC
If this node should join an existing cluster, you can reconfigure this with
'/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token <token-here>'
after creating an enrollment token on your existing cluster.
You can complete the following actions at any time:
Reset the password of the elastic built-in superuser with 
'/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic'.
Generate an enrollment token for Kibana instances with 
 '/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana'.
Generate an enrollment token for Elasticsearch nodes with 
'/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node'.
-------------------------------------------------------------------------------------------------
### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd
 sudo systemctl daemon-reload
 sudo systemctl enable elasticsearch.service
### You can start elasticsearch service by executing
 sudo systemctl start elasticsearch.service

上面显示了 elastic 超级用户的密码已经 kibana 的 enrollment token 等信息。如果这个时候我们直接启动 elasticsearch 服务，那么它将顺利启动并运行。假如你之前已经生成过自己的证书，那么这个时候，你可以直接进行配置 config/elasticsearch.yml 文件即可。如果你没有，请阅读下一节来创建自己的证书。

创建证书

创建根证书

我们使用如下的命令来生成根证书：

/usr/share/elasticsearch/bin/elasticsearch-certutil ca --silent --pem -out config/certs/ca.zip

我们去 Elasticsearch 的配置文件目录进行查看：


root@ubuntu2004:/usr/share/elasticsearch/config/certs# pwd
/usr/share/elasticsearch/config/certs
root@ubuntu2004:/usr/share/elasticsearch/config/certs# ls
ca.zip

我们接下来解压缩上面得到的 ca.zip 文件：


root@ubuntu2004:/usr/share/elasticsearch# pwd
/usr/share/elasticsearch
root@ubuntu2004:/usr/share/elasticsearch# unzip config/certs/ca.zip -d config/certs
Archive:  config/certs/ca.zip
   creating: config/certs/ca/
  inflating: config/certs/ca/ca.crt  
  inflating: config/certs/ca/ca.key

上面显示，ca.zip 含有两个文件 ca.crt 及 ca.key。

为各个节点生成证书文件

我们在 /usr/share/elasticsearch/config/certs 目录底下创建一个 instances.yml 文件，它将包含我们要使用 SSL 保护的不同节点的实例。就我而言，我的机器的情况如下：


root@ubuntu2004:/usr/share/elasticsearch# ifconfig | grep inet
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255
        inet 192.168.0.8  netmask 255.255.255.0  broadcast 192.168.0.255
        inet6 fe80::d246:4880:928b:f508  prefixlen 64  scopeid 0x20<link>
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
root@ubuntu2004:/usr/share/elasticsearch# hostname
ubuntu2004

如上所示，我当前的机器的 IP 地址为 192.168.0.8，而我的 hostname 是 ubuntu2004。我们甚至可以在 /etc/hosts 中添加如下的项：


127.0.0.1 localhost
192.168.0.8 parallels
192.168.0.8 ubuntu2004

这样当我们 ping ubuntu2004 时，它的响应是：


ping ubuntu2004
PING ubuntu2004 (192.168.0.8) 56(84) bytes of data.
64 bytes from parallels (192.168.0.8): icmp_seq=1 ttl=64 time=0.112 ms
64 bytes from parallels (192.168.0.8): icmp_seq=2 ttl=64 time=0.250 ms

/usr/share/elasticsearch/config/certs/instances.yml


instances:
    - name: elasticsearch1
      dns:
        - localhost
        - ubuntu2004
      ip:
        - "192.168.0.8"
    - name: elasticsearch2
      dns:
        - localhost
        - ubuntu2204
      ip:
        - "192.168.0.9"
    - name: elasticsearch3
      dns:
        - localhost
        - mac
      ip:
        - "192.168.0.3"
    - name: "kibana"
      ip:
        - "192.168.0.8"

在上面，我们列举了三个节点的 Elasticsearch。根据你实际的使用情况，你可以添加或减少。在本文的实例中，我将创建一个单节点的 IP 地址为 192.168.0.8 的 Elasticsearch 集群。我们使用如下的命令：

/usr/share/elasticsearch/bin/elasticsearch-certutil cert --silent --pem -out config/certs/certs.zip --in config/certs/instances.yml --ca-cert config/certs/ca/ca.crt --ca-key config/certs/ca/ca.key


root@ubuntu2004:/usr/share/elasticsearch# pwd
/usr/share/elasticsearch
root@ubuntu2004:/usr/share/elasticsearch# ls config/certs/
ca  ca.zip  instances.yml
root@ubuntu2004:/usr/share/elasticsearch# /usr/share/elasticsearch/bin/elasticsearch-certutil cert --silent --pem -out config/certs/certs.zip --in config/certs/instances.yml --ca-cert config/certs/ca/ca.crt --ca-key config/certs/ca/ca.key
root@ubuntu2004:/usr/share/elasticsearch# ls config/certs
ca  ca.zip  certs.zip  instances.yml

从上面，我们可以看出来它生成了一个叫做 certs.zip 的文件。

我们接下来使用如下的命令来解压缩上面得到的 certs.zip 文件：


root@ubuntu2004:/usr/share/elasticsearch# pwd
/usr/share/elasticsearch
root@ubuntu2004:/usr/share/elasticsearch# ls config/certs/
ca  ca.zip  instances.yml
root@ubuntu2004:/usr/share/elasticsearch# /usr/share/elasticsearch/bin/elasticsearch-certutil cert --silent --pem -out config/certs/certs.zip --in config/certs/instances.yml --ca-cert config/certs/ca/ca.crt --ca-key config/certs/ca/ca.key
root@ubuntu2004:/usr/share/elasticsearch# ls config/certs
ca  ca.zip  certs.zip  instances.yml
root@ubuntu2004:/usr/share/elasticsearch# unzip config/certs/certs.zip -d config/certs
Archive:  config/certs/certs.zip
   creating: config/certs/elasticsearch1/
  inflating: config/certs/elasticsearch1/elasticsearch1.crt  
  inflating: config/certs/elasticsearch1/elasticsearch1.key  
   creating: config/certs/elasticsearch2/
  inflating: config/certs/elasticsearch2/elasticsearch2.crt  
  inflating: config/certs/elasticsearch2/elasticsearch2.key  
   creating: config/certs/elasticsearch3/
  inflating: config/certs/elasticsearch3/elasticsearch3.crt  
  inflating: config/certs/elasticsearch3/elasticsearch3.key  
   creating: config/certs/kibana/
  inflating: config/certs/kibana/kibana.crt  
  inflating: config/certs/kibana/kibana.key

如上所示，我们可以看到所有生成的证书文件：


root@ubuntu2004:/usr/share/elasticsearch# tree -L 4 config/
config/
└── certs
    ├── ca
    │   ├── ca.crt
    │   └── ca.key
    ├── ca.zip
    ├── certs.zip
    ├── elasticsearch1
    │   ├── elasticsearch1.crt
    │   └── elasticsearch1.key
    ├── elasticsearch2
    │   ├── elasticsearch2.crt
    │   └── elasticsearch2.key
    ├── elasticsearch3
    │   ├── elasticsearch3.crt
    │   └── elasticsearch3.key
    ├── instances.yml
    └── kibana
        ├── kibana.crt
        └── kibana.key

我们接下来把上面生成的证书拷贝到 /etc/elasticsearch/certs 下面去。


root@ubuntu2004:/usr/share/elasticsearch# pwd
/usr/share/elasticsearch
root@ubuntu2004:/usr/share/elasticsearch# cd config/certs/
root@ubuntu2004:/usr/share/elasticsearch/config/certs# ls
ca  ca.zip  certs.zip  elasticsearch1  elasticsearch2  elasticsearch3  instances.yml  kibana
root@ubuntu2004:/usr/share/elasticsearch/config/certs# cp -R ca /etc/elasticsearch/certs/ 
root@ubuntu2004:/usr/share/elasticsearch/config/certs# cp -R elasticsearch1 /etc/elasticsearch/certs/

这样在 /etc/elasticsearch/certs 下的文件如下：


root@ubuntu2004:/etc/elasticsearch/certs# ls
ca  elasticsearch1  http_ca.crt  http.p12  transport.p12
root@ubuntu2004:/etc/elasticsearch/certs# tree -L 2
.
├── ca
│   ├── ca.crt
│   └── ca.key
├── elasticsearch1
│   ├── elasticsearch1.crt
│   └── elasticsearch1.key
├── http_ca.crt
├── http.p12
└── transport.p12

请注意上面的 http_ca.crt，http.p12 及 transport.p12 是安装时默认生成的证书文件。

我们接下来修改证书文件的权限：


chown -R root:elasticsearch ca
chown -R root:elasticsearch elasticsearch1/


root@ubuntu2004:/etc/elasticsearch# cd certs
root@ubuntu2004:/etc/elasticsearch/certs# ls -alh
total 40K

-rw-r--r-- 1 root elasticsearch 1.7K May 12 17:35 ca.key

配置 Elasticsearch 节点

在上面我们已经生成了 Elasticsearch 及 Kibana 的证书文件。我们接下来使用上面的文件来对 Elasticsearch 进行配置：

/etc/elasticsearch/elasticsearch.yml


cluster.name: es-demo
network.host: 192.168.0.8
http.port: 9200
 
# Enable security features
xpack.security.enabled: true
 
xpack.security.enrollment.enabled: true
 
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: true
  key: /etc/elasticsearch/certs/elasticsearch1/elasticsearch1.key
  certificate: /etc/elasticsearch/certs/elasticsearch1/elasticsearch1.crt
  certificate_authorities: /etc/elasticsearch/certs/ca/ca.crt
  verification_mode: certificate
 
 
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: true
  key: /etc/elasticsearch/certs/elasticsearch1/elasticsearch1.key
  certificate: /etc/elasticsearch/certs/elasticsearch1/elasticsearch1.crt
  certificate_authorities: /etc/elasticsearch/certs/ca/ca.crt
  verification_mode: certificate

我们需要做如上的配置。

启动 Elasticsearch

我们使用如下的命令来启动 elasticsearch 服务：


root@ubuntu2004:~# service elasticsearch status
● elasticsearch.service - Elasticsearch
     Loaded: loaded (/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled)
     Active: inactive (dead)

May 12 17:59:34 ubuntu2004 systemd[1]: Starting Elasticsearch...
May 12 17:59:43 ubuntu2004 systemd[1]: Started Elasticsearch.

我们可以看到 elasticsearch 服务已经启动。我们可以通过如下的命令来查看它的日志：

journalctl -u elasticsearch

我们使用如下的命令来检查安装是否成功：

curl -k -u elastic:xsYCh*5qOz7hSpkH-fHC https://192.168.0.8:9200

在上面，请用在安装时提供的 elastic 超级用户密码来进行替换：


curl -k -u elastic:xsYCh*5qOz7hSpkH-fHC https://192.168.0.8:9200
{
  "name" : "ubuntu2004",
  "cluster_name" : "es-demo",
  "cluster_uuid" : "2-rpYdtJQeOifbwljN2LHA",
  "version" : {
    "number" : "8.7.1",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "f229ed3f893a515d590d0f39b05f68913e2d9b53",
    "build_date" : "2023-04-27T04:33:42.127815583Z",
    "build_snapshot" : false,
    "lucene_version" : "9.5.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

很显然，我们的安装时成功的。

安装 Kibana

我们可以参考文章 “Kibana：使用 Debian 安装包来安装 Kibana 8.x” 来安装 Kibana。由于我们已经修改了 Elasticsearch 的证书，我们需要对 Kibana 进行配置。在运行如下的命令之后：

sudo apt-get update && sudo apt-get install kibana

我们针对 Kibana 进行配置。首先，我们把证书拷贝过来：


root@ubuntu2004:/usr/share/elasticsearch/config/certs# pwd
/usr/share/elasticsearch/config/certs
root@ubuntu2004:/usr/share/elasticsearch/config/certs# ls
ca  ca.zip  certs.zip  elasticsearch1  elasticsearch2  elasticsearch3  instances.yml  kibana
root@ubuntu2004:/usr/share/elasticsearch/config/certs# cp -R ca /etc/kibana/certs/ 
root@ubuntu2004:/usr/share/elasticsearch/config/certs# cp -R kibana /etc/kibana/certs/

我们可以在 Kibana 的配置文件目录看到文件：


root@ubuntu2004:/etc/kibana/certs# ls -alh
total 16K
drwxr-sr-x 4 root kibana 4.0K May 14 10:27 .
drwxr-s--- 3 root kibana 4.0K May 14 10:22 ..
drwxr-sr-x 2 root kibana 4.0K May 14 09:59 ca
drwxr-sr-x 2 root kibana 4.0K May 12 18:17 kibana
root@ubuntu2004:/etc/kibana/certs# tree -L 2
.
├── ca
│   ├── ca.crt
│   └── ca.key
└── kibana
    ├── kibana.crt
    └── kibana.key

我们可以利用上面的证书文件来配置 /etc/kibana/kibana.yml 文件。上面显示我们的证书文件的所有权是 root:kibana。如果你有不对的，请进行相应修改。

创建 elastic/kibana 服务账号

根据文档 https://www.elastic.co/guide/en/elasticsearch/reference/current/service-accounts.html，我们创建一个 elastic/kibana 服务账号。我们在 terminal 下打入如下的命令：


root@ubuntu2004:/usr/share/elasticsearch/bin# ls
elasticsearch                          elasticsearch-geoip             elasticsearch-setup-passwords

root@ubuntu2004:/usr/share/elasticsearch/bin# ./elasticsearch-service-tokens create elastic/kibana kibana-token
SERVICE_TOKEN elastic/kibana/kibana-token = AAEAAWVsYXN0aWMva2liYW5hL2tpYmFuYS10b2tlbjpBQlVPWWpGRlNVQ2hhMWdlNzBpUXZn

我们记下这个 service token。将在下面的配置中使用。

我们是使用如下的命令来把上面的 service token 放进 keystore。我们可以在如下的地址发现已经存在一个叫做 kibana.keystore 的文件。我们无需去重新创建这个文件。


root@ubuntu2004:/etc/kibana# ls
certs  kibana.keystore  kibana.yml  node.options

参考链接 https://www.elastic.co/guide/en/kibana/current/secure-settings.html。我们打入如下的命令：

root@ubuntu2004:/usr/share/kibana/bin# ./kibana-keystore list

上面显示还没有任何的值在里面。我们使用如下的命令：


root@ubuntu2004:/usr/share/kibana/bin# pwd
/usr/share/kibana/bin

配置 Kibana

/etc/kibana/kibana.yml


server.port: 5601
server.host: "0.0.0.0"
server.publicBaseUrl: "https://ubuntu2004:5601"
 
server.ssl.enabled: true
server.ssl.certificate: /etc/kibana/certs/kibana/kibana.crt
server.ssl.key: /etc/kibana/certs/kibana/kibana.key
 
elasticsearch.hosts: ["https://192.168.0.8:9200"]
 
elasticsearch.ssl.verificationMode: full
elasticsearch.ssl.certificateAuthorities: [/etc/kibana/certs/ca/ca.crt]

我们接下来启动 kibana 服务：

service kibana start

我们查看它的状态：

我们回到 Elasticsearch 的配置目录：

修改过后，我们再次重新启动 elasticsearch 服务：

service elasticsearch restart

我们再次重新启动 kibana 服务：

service kibana restart

我们再查看 kibana 服务的状态：

这次我们没有看到错误信息了。

我们在浏览器中打入地址 https://localhost:5601：

这样就成功地登录 Kibana 了。
