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/datalog

cd /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 zookeeper

docker 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:7.12.0


2、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.yml


4、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/data

2、下载并查看镜像
docker search minio
docker pull minio/minio

3、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secretKey

7、创建bucket 和 上传文件
