Docker安装Elasticsearch和Kibana 8.4.1

## 安装Elasticsearch

#### 环境准备

因为我们要安装es和kibana,我们先为他们创建网络

```shell
docker network create elastic
```

拉取docker镜像，这里我们安装8.4.1

```shell
docker pull elasticsearch:8.4.1
```

#### 启动es

```shell
docker run --name myes --net elastic 
-p 9200:9200 -p 9300:9300 
-e "discovery.type=single-node" 
-e CLI_JAVA_OPTS="-Xms128m -Xmx1024m" 
-v /data/service/es/plugins:/usr/share/elasticsearch/plugins 
-it elasticsearch:8.4.1
```

启动es之后我们可以看到输出日志末尾有如下日志：

```shell
-> Elasticsearch security features have been automatically configured!
-> Authentication is enabled and cluster connections are encrypted.

->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  vSmuF==WnQl*V8m4APAc

->  HTTP CA certificate SHA-256 fingerprint:
  fdbc10be17db909e1ea7d2b6dfee6727531f30b1b12ca98a5a4eac8b83739d28

->  Configure Kibana to use this cluster:
* Run Kibana and click the configuration link in the terminal when Kibana starts.
* Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

-> Configure other nodes to join this cluster:
* Copy the following enrollment token and start new Elasticsearch nodes with `bin/elasticsearch --enrollment-token <token>` (valid for the next 30 minutes):
  eyJ2ZXIiOiI4LjQuMSIsImFkciI6WyIxNzIuMTguMC4yOjkyMDAiXSwiZmdyIjoiZmRiYzEwYmUxN2RiOTA5ZTFlYTdkMmI2ZGZlZTY3Mjc1MzFmMzBiMWIxMmNhOThhNWE0ZWFjOGI4MzczOWQyOCIsImtleSI6ImphZF9RWVlCWUszMVg5NThtbFM5OlBHb0dzNkd2VEx1OFlJSkhmby04OWcifQ==

If you're running in Docker, copy the enrollment token and run:
  `docker run -e "ENROLLMENT_TOKEN=<token>" docker.elastic.co/elasticsearch/elasticsearch:8.4.1`
```

可以看到其中两个比较重要的日志

```shell
->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  vSmuF==WnQl*V8m4APAc

和

第一行为es密码 账户为es， 并且之指明了， 用户名为elastic 和重置密码的命令

第二个为kibana密码，并且该密码有效期只有三十分钟，如果过期参考最下边的解决方案。

#### 启动Kibana

拉取kibana镜像,这里需要注意，因为ES多个组件之间需要保持版本一致。

```shell
docker pull kibana:8.4.1
```

```shell
docker run --name mykb --net elastic -p 5601:5601 kibana:8.4.1
```

启动后日志输出如下：

```shell
[root@localhost ~]# docker run --name mykb --net elastic -p 5601:5601 kibana:8.4.1
[2023-02-11T17:30:09.304+00:00][INFO ][node] Kibana process configured with roles: [background_tasks, ui]
[2023-02-11T17:30:23.917+00:00][INFO ][http.server.Preboot] http server running at http://0.0.0.0:5601

[2023-02-11T17:30:23.998+00:00][INFO ][root] Holding setup until preboot stage is completed.

i Kibana has not been configured.

Go to http://0.0.0.0:5601/?code=696159 to get started.
```

这个时候我们访问

```shell
http://{{ip}}:5601
```

点击Configure Elastic

提示如如下页面，

进入kibana容器中查看到对应日志数据有验证码日志：

```shell
Your verification code is:  696 159
```

输入验证码之后点击Verify,可以看到kibana初始化完成

此处输入ES密码即可登录kibana

##### kibana令牌过期如何重新生成？

1. 登录es实例：

```shell
docker exec  -it myes /bin/bash
```

1. 执行命令重新生成

```shell
./elasticsearch-create-enrollment-token -s kibana --url "https://172.18.0.2:9200"
eyJ2ZXIiOiI4LjQuMSIsImFkciI6WyIxNzIuMTguMC4yOjkyMDAiXSwiZmdyIjoiZmRiYzEwYmUxN2RiOTA5ZTFlYTdkMmI2ZGZlZTY3Mjc1MzFmMzBiMWIxMmNhOThhNWE0ZWFjOGI4MzczOWQyOCIsImtleSI6ImpxZkRRWVlCWUszMVg5NThFbFNDOi1wUHN2OGczU0htYTF1NnlYVGhULXcifQ==
```

其中ip地址为es地址
