Docker学习，常用安装：Zookeeper、ES、Minio
一、Docker安装Zookeeper
##查询zookeeper镜像
docker search zookeeper
##拉去zookeeper镜像
docker pull zookeeper:latest##本地创建zookeeper的挂载目录
mkdir -p /opt/software/myfile/zookeeper/conf
mkdir -p /opt/software/myfile/zookeeper/data
mkdir -p /opt/software/myfile/zookeeper/datalogcd /opt/software/myfile/zookeeper##运行一个zookeeper 复制它的配置文件到本地
docker run --name zookeeper -p 2181:2181 -d zookeeperdocker container cp zookeeper:/conf .##关闭并删除docker
docker stop zookeeper
docker rm zookeeper##启动一个新的zookeeper容器，并挂载本地配置和数据目录
docker run --name zookeeper \
-p 2181:2181 \
-v /opt/software/myfile/zookeeper/conf:/conf \
-v /opt/software/myfile/zookeeper/data:/data \
-v /opt/software/myfile/zookeeper/datalog:/datalog \
--restart=always \
-d zookeeper二、Docker安装Elasticsearch
1、拉取镜像docker pull elasticsearch:7.12.02、创建本地挂载目录mkdir -p /opt/software/myfile/elasticsearch/config
mkdir -p /opt/software/myfile/elasticsearch/data
mkdir -p /opt/software/myfile/elasticsearch/plugins权限设置
sudo chmod -R 777 /opt/software/myfile/elasticsearch/3、配置文件echo "http.host: 0.0.0.0" >> /opt/software/myfile/elasticsearch/config/elasticsearch.yml4、创建容器docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \-e "discovery.type=single-node" \-e ES_JAVA_OPTS="-Xms84m -Xmx512m" \-v /opt/software/myfile/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \-v /opt/software/myfile/elasticsearch/data:/usr/share/elasticsearch/data \-v /opt/software/myfile/elasticsearch/plugins:/usr/share/elasticsearch/plugins \-d elasticsearch:7.12.0说明：-p 端口映射
-e discovery.type=single-node 单点模式启动
-e ES_JAVA_OPTS="-Xms84m -Xmx512m"：设置启动占用的内存范围
-v 目录挂载
-d 后台运行5、其他命令docker ps 查看是否启动
docker logs elasticsearch 启动日志查询
docker restart elasticsearch 重启
docker exec -it elasticsearch bash 进入异常处理：
异常一：文件夹未设置所有用户读写执行权限，处理：sudo chmod -R 777 /opt/software/myfile/elasticsearch/
三、Docker安装Minio
1、先准备Minio外部挂载配置文件(/opt/software/myfile/minio/conf)和存储上传文件的目录(/opt/software/myfile/minio/data)
mkdir -p /opt/software/myfile/minio/conf
mkdir -p /opt/software/myfile/minio/data2、下载并查看镜像
docker search minio
docker pull minio/minio3、创建Minio容器并运行
docker run -p 9000:9000 -p 9090:9090 \--net=host \--name minio \-d --restart=always \-e "MINIO_ACCESS_KEY=admin" \-e "MINIO_SECRET_KEY=admin123" \-v /opt/software/myfile/minio/data:/data \-v /opt/software/myfile/minio/conf:/root/.minio \minio/minio server \/data --console-address ":9090" -address ":9000"9000是minio的服务端端口 9090是客户端端口
MINIO_ACCESS_KEY 账号
MINIO_SECRET_KEY 密码4、登录：http://192.168.73.107:9090 admin admin123
5、创建组和用户
6、创建accessKey和secretKeyTIG1FU12193G6LPOOQXGPtMOEjBXMZ+jRkMRlOQPWEq2958ceIGcImxYiEpD7、创建bucket 和 上传文件
