# 开放端口
EXPOSE 9200
EXPOSE 5601
EXPOSE 9300

执行命令创建镜像 docker build -t"txz/elk:latest"

创建完成之后使用命令创建容器

docker run -itd --privileged=true -p 9300:9300 -p 9200:9200 -p 5601:5601 --name elk <image_id> /usr/sbin/init

创建完成之后进入容器 docker exec -it elk /bin/bash

进入容器之后安装x-pack插件

elasticsearch-plugin install x-pack
kibana-plugin install x-pack

完成之后启动elasticsearch $ELASTICSEARCH_PATH/bin/elasticsearch

设置密码, 注意需要密码保存起来

$ELASTICSEARCH_PATH/bin/x-pack/setup-passwords auto

修改kibana目录下config/kibana.yml

elasticsearch.username: "kibana"
elasticsearch.password: "<pwd>" 填入上一步获取到的kibana账户的密码

启动kibana $KIBANA_PATH/bin/kibana

开启成功之后测试命令，注意开启了x-pack之后需要设置Authorization. Basic 后的内容为

base64(kibana:wQCiFkNKxrIKyhNWDC1v) 的内容

curl -XGET "[<http://localhost:9200/_count?pretty>](<http://localhost:9200/_count?pretty>)" -H"Content-Type: application/json Authorization: Basic ZWxhc3RpYzpyb290dHh6" -d'{"query":{"match_all":{}}}'

如果正确返回，说明安装成功

通过访问 http://localhost:5601/ 访问kibana
