# docker启动的elasticsearch-ik服务
|
||
|
||
## 介绍
|
||
|
||
整合`elasticsearch`和`analysis-ik`的一键启动容器，选用版本`7.17.18`。
|
||
|
||
## 用法
|
||
|
||
```sh
|
||
docker compose up -d
|
||
```
|
||
|
||
### 安全问题
|
||
|
||
在`config/elasticsearch.yml`中已经配置了`xpack.security.enabled: true`，所以在首次启动容器后需要为elasticsearch中的各个账号设置密码：
|
||
|
||
```sh
|
||
docker exec -it es bin/elasticsearch-setup-passwords interactive
|
||
```
|
||
|
||
接下来就可以按照提示分别为各个用户设置密码：
|
||
|
||
- elastic
|
||
- apm_system
|
||
- kibana
|
||
- kibana_system
|
||
- logstash_system
|
||
- beats_system
|
||
- remote_monitoring_user
|
||
|
||
密码生效后会写入`data`目录中，所在容器是可以`down`掉的。
|
||
|
||
## 问题
|
||
|
||
如果服务启动失败，可能是文件夹文件问题，修改`config`目录和`data`目录的权限：
|
||
|
||
```sh
|
||
chmod 777 -R data
|
||
chmod 755 -R config
|
||
```
|
||
|
||
然后再试着重新启动服务。
|
||
|
||
## arm64平台
|
||
|
||
如果要在arm平台上使用，请将`docker-compose.yml`文件中的镜像标签改为`wandoubaba517/elasticsearch-ik:7.17.18`。
