[大数据]运维(14) docker-compose部署Elasticsearch并设置账号密码

一、前言

本文将基于docker-compose部署Elasticsearch并设置账号密码。

1. docker-compose version 1.29.2, build 5becea4c
2. elasticsearch:7.14.1
3. kibana:7.14.1

可参考：https://gitee.com/zhengqingya/docker-compose

二、docker-compose部署Elasticsearch

# 准备
git clone https://gitee.com/zhengqingya/docker-compose.git
cd docker-compose/Liunx
# 当前目录下所有文件赋予权限(读、写、执行)
chmod -R 777 ./elasticsearch
# 运行
docker-compose -f docker-compose-elasticsearch.yml -p elasticsearch up -d
# 运行后，再次给新创建的文件赋予权限
chmod -R 777 ./elasticsearch

三、访问

1. ES访问地址：ip地址:9200
   默认账号密码：elastic/123456
2. kibana访问地址：ip地址:5601/app/dev_tools#/console
   默认账号密码：elastic/123456

四、ES密码

1、设置ES密码

# 进入容器
docker exec -it elasticsearch /bin/bash
# 设置密码-随机生成密码
# elasticsearch-setup-passwords auto
# 设置密码-手动设置密码
elasticsearch-setup-passwords interactive
# 访问
curl 127.0.0.1:9200 -u elastic:123456

2、修改ES密码

# 修改elastic密码为123456 (注：执行命令时会让认证之前账号密码)
curl -H "Content-Type:application/json" -XPOST -u elastic 'http://127.0.0.1:9200/_xpack/security/user/elastic/_password' -d '{ "password" : "123456" }'

五、其他
