接上篇:Elasticsearch 7.x 的安装与简单配置(阿里云Ubuntu)
Cerebro 是一个使用 Scala,Play Framework,AngularJS 和 Bootstrap 构建的开源(MIT许可)elasticsearch web管理工具。 https://github.com/lmenezes/c...
系统环境
- 操作系统:Ubuntu 18.04 LTS(阿里云)
- 系统IP
# 内网,私有地址
172.内.内.内
# 外网,公有地址
112.外.外.外
- Elasticsearch 版本:7.2
- Kibana 版本:7.2
- Cerebro 版本: 0.8.3
- Docker 版本:18.09
安装 dcoker 及组件
- 安装 docker
$ sudo apt install docker
# 将当前用户加入 docker 组,避免 root 权限运行 docker 命令
$ sudo usermod -aG docker ${USER}
$ docker --version
Docker version 18.09.7, build 2d0083d
- 安装 docker.io
$ sudo apt install docker.io
- 安装 docker-compose
$ sudo apt install docker-compose
$ docker-compose --version
docker-compose version 1.17.1, build unknown
配置 docker 镜像加速器
- 阿里云控制台 -> 产品与服务 -> 弹性计算 -> 容器镜像服务
创建并启动 docker 容器
- 将 docker-compose.yaml 保持到 Ubuntu 本地目录,内容如下,对原课程 github 上的文件有微调
- 课程 docker-compose.yaml
# docker-compose.yaml

- 在 docker-compose.yaml 所在目录运行以下命令,创建并启动容器
$ docker-compose up
安全组端口
- 本文涉及应该放行的安全组端口有3个
elasticsearch: 9200
kibana: 5601
cerebro: 9000
结果查看
- 查看磁盘挂载信息
$ docker volume ls
DRIVER VOLUME NAME
local docker_es72data1
local docker_es72data2
$ docker volume inspect docker_es72data1
