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：
-
Security：如何安装 Elastic SIEM 和 EDR
-
Elasticsearch: 使用 Debian 安装包来安装 Elasticsearch 8.x
-
Elasticsearch：使用 Docker compose 来一键部署 Elastic Stack 8.x
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：

--------------------------- Security autoconfiguration information ------------------------------
Authentication and authorization are enabled.
TLS for the transport and HTTP layers is enabled and configured.
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:

- 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.keyroot@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

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/

├── 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

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

├── 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：

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

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：

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
{

"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 kibanaroot@ubuntu2004:~# sudo apt-get update && sudo apt-get install kibana

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

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# pwd
