Elasticsearch的安装

导入 elasticsearch PGP密钥

我们使用 Elasticsearch 签名密钥（PGP 密钥D88E42B4，可从https://pgp.mit.edu获取）和指纹对所有包进行签名 ：

4609 5ACC 8548 582C 1A26 99A9 D27D 666C D88E 42B4

下载并安装公共签名密钥：

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg

安装

使用APT安装

在使用apt安装前，先需要安装apt-transport-https

sudo apt-get install apt-transport-https

将存储库定义保存到/etc/apt/sources.list.d/elastic-8.x.list

echo "deb [signed-by=/usr/share/keyrings/elasticsearch-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list

使用以下命令安装 Elasticsearch

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

手动下载安装

首先，先到elasticsearch查找你所需要的下载的版本链接。

然后使用下面语句下载

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.8.2-amd64.deb
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.8.2-amd64.deb.sha512

比较下载的Debian软件包的 SHA 和发布的SHA是否一致

root@qhdata-dev:/home/qhdata/elasticsearch# shasum -a 512 -c elasticsearch-8.8.2-amd64.deb.sha512 
elasticsearch-8.8.2-amd64.deb: OK
root@qhdata-dev:/home/qhdata/elasticsearch# 

安装

sudo dpkg -i elasticsearch-8.8.2-amd64.deb

启动elasticsearch安全功能

安装 Elasticsearch 时，默认启用并配置安全功能。安装 Elasticsearch 时，会自动进行以下安全配置：

• elastic启用身份验证和授权，并为内置超级用户 生成密码。
• 为传输层和 HTTP 层生成 TLS 的证书和密钥，并使用这些密钥和证书启用和配置 TLS。

密码、证书和密钥将输出到您的终端。例如：

root@qhdata-dev:/home/qhdata/elasticsearch# sudo dpkg -i elasticsearch-8.8.2-amd64.deb
Selecting previously unselected package elasticsearch.
(Reading database ... 153850 files and directories currently installed.)
Preparing to unpack elasticsearch-8.8.2-amd64.deb ...
Unpacking elasticsearch (8.8.2) ...
Setting up elasticsearch (8.8.2) ...
--------------------------- 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 : <password>

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
root@qhdata-dev:/home/qhdata/elasticsearch# 

将Security autoconfiguration information的信息保存在security_autoconfiguration_information.cfg中，方便后续查看。

重新配置节点以加入现有集群

安装 Elasticsearch 时，安装过程默认配置单节点集群。如果您希望节点加入现有集群，请在首次启动新节点之前在现有节点上生成注册令牌。

在现有集群中的任何节点上，生成节点注册令牌：

/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node

复制注册令牌，该令牌将输出到您的终端。
在新的 Elasticsearch 节点上，将注册令牌作为参数传递给该 elasticsearch-reconfigure-node工具：

/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token <enrollment-token>

Elasticsearch 现在已配置为加入现有集群。
使用启动新节点systemd

启用系统索引的自动创建功能

一些商业功能会自动在 Elasticsearch 中创建索引。默认情况下，Elasticsearch 配置为允许自动创建索引，无需执行任何其他步骤。但是，如果您在 Elasticsearch 中禁用了自动索引创建，则必须进行配置 action.auto_create_index以elasticsearch.yml允许商业功能创建以下索引：

action.auto_create_index: .monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*

运行Elasticsearch(在systemd下)

要将 Elasticsearch 配置为在系统启动时自动启动，请运行以下命令：

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

Elasticsearch 可以按如下方式启动和停止：

sudo systemctl start elasticsearch.service  
sudo systemctl stop elasticsearch.service

这些命令不提供有关 Elasticsearch 是否成功启动的反馈。相反，此信息将写入位于/var/log/elasticsearch/.
如果您的 Elasticsearch 密钥库受密码保护，则需要 systemd使用本地文件和 systemd 环境变量提供密钥库密码。该本地文件在存在时应受到保护，并且一旦 Elasticsearch 启动并运行即可安全删除。

echo "keystore_password" > /path/to/my_pwd_file.tmp
chmod 600 /path/to/my_pwd_file.tmp
sudo systemctl set-environment ES_KEYSTORE_PASSPHRASE_FILE=/path/to/my_pwd_file.tmp
sudo systemctl start elasticsearch.service

检查Elasticsearch是否正在运行

您可以通过向localhost:9200发送 HTTPS 请求来测试您的 Elasticsearch 节点是否正在运行：

curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic https://localhost:9200 

然后输入安装期间生成的超级用户elastic的密码。返回如下。

root@qhdata-dev:/home/qhdata/elasticsearch# curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic https://localhost:9200
Enter host password for user 'elastic':
{
  "name" : "qhdata-dev",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "un55kUpqQ9iFGEfp5UUQ5g",
  "version" : {
    "number" : "8.8.2",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "98e1271edf932a480e4262a471281f1ee295ce6b",
    "build_date" : "2023-06-26T05:16:16.196344851Z",
    "build_snapshot" : false,
    "lucene_version" : "9.6.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}
root@qhdata-dev:/home/qhdata/elasticsearch# 

Elasticsearch配置

外网访问

修改/etc/elasticsearch/elasticsearch.yml

然后重启服务，在外网页中输入https://<host>:9200，进入网页后会提示输入用户跟密码，我这里使用的是超级用户elastic与对应的密码。然后即可登陆插卡该elasticsearch的信息。

第三方包安装

elasticsearch-analysis-ik中文分词

官方网址：https://github.com/medcl/elasticsearch-analysis-ik
首先，在https://github.com/medcl/elasticsearch-analysis-ik/releases中找到对应的版本。

然后使用elasticsearch-plugin安装（从版本v5.5.1开始支持）

cd /usr/share/elasticsearch/bin
./elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v8.8.2/elasticsearch-analysis-ik-8.8.2.zip

安装完后再plugins中可以查看到对应的包

root@qhdata-dev:/usr/share/elasticsearch/bin# cd /usr/share/elasticsearch/plugins
root@qhdata-dev:/usr/share/elasticsearch/plugins# ls -r
analysis-ik
root@qhdata-dev:/usr/share/elasticsearch/plugins# 

重启elasticsearch

Enterprise Search的安装

参考文章：https://www.elastic.co/cn/downloads/enterprise-search
服务器系统：Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-153-generic x86_64)
enterprise search版本：8.8.2(软件包发行版)

安装

首先，先到enterprise-search查找你所需要的下载的版本链接。

然后使用下面语句下载

wget https://artifacts.elastic.co/downloads/enterprise-search/enterprise-search-8.8.2.deb
wget https://artifacts.elastic.co/downloads/enterprise-search/enterprise-search-8.8.2.deb.sha512

比较下载的Debian软件包的 SHA 和发布的SHA是否一致

root@qhdata-dev:/home/qhdata/elasticsearch# shasum -a 512 -c enterprise-search-8.8.2.deb.sha512
enterprise-search-8.8.2.deb: OK
root@qhdata-dev:/home/qhdata/elasticsearch# 

安装

sudo dpkg -i enterprise-search-8.8.2.deb

启动elasticsearch并查找http证书

当您第一次启动 Elasticsearch 时，会自动进行以下安全配置：

• elastic启用身份验证和授权，并为内置超级用户 生成密码。
• 为传输层和 HTTP 层生成 TLS 的证书和密钥，并使用这些密钥和证书启用和配置 TLS。

密码、证书和密钥将输出到您的终端。
http_ca.crt在单独的终端中，找到Elasticsearch 创建的文件的绝对路径名。然后使用find指令查找。

root@qhdata-dev:/etc/elasticsearch# find $(pwd) -name 'http_ca.crt'
/etc/elasticsearch/certs/http_ca.crt
root@qhdata-dev:/etc/elasticsearch# 

然后记录下证书的路径

enterprise search配置

修改/usr/share/enterprise-search/config/enterprise-search.yml

然后使用bin/enterprise-search执行，第一次由于没有设置secret_management.encryption_keys会提示报错，同时会产生对应的key。

root@qhdata-dev:/usr/share/enterprise-search# bin/enterprise-search
