0x00 概述

为了避开虚拟机，在基于docker compose的基础上快速启动一套3节点es kibana的测试环境(7.13.3)；

要求理解docker原理和熟悉基本docker操作，本集群仅供测试用。

0x01 准备

1.1 电脑win或者mac安装好docker desktop

1.2  将docker镜像源改为国内源，加快镜像下载速度

代码语言：javascript复制
{
  "debug": true,
  "experimental": false,
  "registry-mirrors": [
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com"
  ]
}

点击Apply & Reset.

1.3 docker提前下载好镜像，以便快速启动

代码语言：javascript复制
docker pull elasticsearch:7.13.3
docker pull kibaba:7.13.3

1.4 使用ES提前制作elastic-certificates.p12，方便挂载

制作方法参考这里，存在D盘es-cluster目录，挂载路径为/d/es-cluster/elastic-certificates.p12

1.5 在本地提前新建es存储用的文件夹，方便挂在

es有存储数据的需求，这里将数据直接挂载到本机，存在D盘es-cluster目录，3个es实例对应的分别为该目录下的es01，es02，es03，挂载路径为/d/es-cluster/es01,/d/es-cluster/es02,/d/es-cluster/es03

0x02 启动测试集群

2.1 docker-compose.yml文件

新建docker-compose.yml，放在D盘es-cluster目录，路径为D:es-clusterdocker-compose.yml

docker-compose.yml (注意参数配置和用户密码)

2.2 启动和关闭

使用命令行进入到D:es-cluster，使用docker compoe up命令启动即可，注意观察日志，集群状态变为Green即可访问Kibana；

docker compose down关闭测试环境

2.3 注意事项

如下命令用于后台启动

代码语言：javascript复制
docker compose up -d

如下命令用于停止测试集群

代码语言：javascript复制
docker compose down

由于ES会存储数据，使用ctrl C停止集群会造成数据损坏或丢失，导致无法再次重启集群，切记。

如果启动报错，或者需要清空集群数据，删除/d/es-cluster/下3个es开头文件夹下面的所有内容，再次启动即可。
