MinIo安装及启动
1. 通过 docker 安装 MinIo
# 搜索是否有 minio 镜像
docker search minio
# 有则拉取镜像
docker pull minio/minio
2. 启动 及配置 MinIo
# 先创建minio 文件存放的位置
mkdir -p /opt/docker/minio/data
# 启动并指定端口
docker run \
-p 5000:9000 \
-p 5001:5001 \
--name minio \
-v /opt/docker/minio/data:/data \
-e "MINIO_ROOT_USER=Jonny" \
-e "MINIO_ROOT_PASSWORD=minioadmin" \
-d minio/minio server /data --console-address ":5001"
# 设置为和 docker 绑定启动,docker 启动则 minio 就启动
docker update --restart=always
这里解释一下 docker 里面的几个参数
-p: 指定端口映射,格式为:主机(宿主)端口:容器端口
-e “MINIO_ROOT_USER=Jonny”: 设置环境变量;
-d: 后台运行容器,并返回容器ID;
-v: 绑定一个卷
3.其他OPTIONS解释
docker run [OPTIONS] IMAGE [COMMAND] [ARG…]
OPTIONS参数说明:
-a stdin: 指定标准输入输出内容类型,可选 STDIN/STDOUT/STDERR 三项;
-d: 后台运行容器,并返回容器ID;
-i: 以交互模式运行容器,通常与 -t 同时使用;
-P: 随机端口映射,容器内部端口随机映射到主机的端口
-p: 指定端口映射,格式为:主机(宿主)端口:容器端口
-t: 为容器重新分配一个伪输入终端,通常与 -i 同时使用;
name=“nginx-lb”: 为容器指定一个名称;
dns 8.8.8.8: 指定容器使用的DNS服务器,默认和宿主一致;
dns-search example.com: 指定容器DNS搜索域名,默认和宿主一致;
-h “mars”: 指定容器的hostname;
-e username=“ritchie”: 设置环境变量;
env-file=[]: 从指定文件读入环境变量;
cpuset=“0-2” or cpuset=“0,1,2”: 绑定容器到指定CPU运行;
-m :设置容器使用内存最大值;
net=“bridge”: 指定容器的网络连接类型,支持 bridge/host/none/container: 四种类型;
link=[]: 添加链接到另一个容器;
expose=[]: 开放一个端口或一组端口;
volume , -v: 绑定一个卷
例如,使用docker镜像nginx:latest以后台模式启动一个容器,并将容器命名为mynginx:
docker run name mynginx -d nginx:latest
使用镜像nginx:latest以后台模式启动一个容器,并将容器的80端口映射到主机随机端口:
docker run -P -d nginx:latest
使用镜像 nginx:latest,以后台模式启动一个容器,将容器的 80 端口映射到主机的 80 端口,主机的目录 /data 映射到容器的 /data:
docker run -p 80:80 -v /data:/data -d nginx:latest
绑定容器的 8080 端口,并将其映射到本地主机 127.0.0.1 的 80 端口上:
docker run -p 127.0.0.1:80:8080/tcp ubuntu bash
使用镜像nginx:latest以交互模式启动一个容器,在容器内执行/bin/bash命令:
docker run -it nginx:latest /bin/bash
SpringBoot 整合 MinIO
1.导入依赖
<!-- https://mvnrepository.com/artifact/io.minio/minio -->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.4.0</version>
</dependency>
2.application.yml 配置信息
minio:
endpoint: http://127.0.0.1:9000 #Minio服务所在地址
bucketName: tulaoda #存储桶名称
accessKey: Jonny #访问的key
secretKey: minioadmin #访问的秘钥
3.MinioConfig.class配置类
@Data
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {
private String endpoint;
private String accessKey;
private String secretKey;
private String bucketName;
@Bean
public MinioClient minioClient() {

这一块的接口慢慢试,主要用的几个接口在上面
报错解决
错误原因:
minio版本太新需要更换成8.2.2的版本

}
主要是因为 :
系统时区与硬件时区不一致导致的
解决步骤如下
- 安装ntp ntpdate
yum -y install ntp ntpdate
- 与时间服务器同步时间
ntpdate 0.asia.pool.ntp.org
- 将系统时间写入硬件时间
hwclock --systohc
报错是因为没有给buckts配置权限策略导致。
解决步骤如下:
方法一 :客户端操作

方法二: 在创建 Bucket 的时候直接设置权限策略[后端修改]
将 MinIOUtil 工具类的创建 Bucket 的方法优化一下
/** * 创建存储bucket * @return Boolean */ public Boolean makeBucket(String bucketName) { try { if (!bucketExists(bucketName)) { minioClient.makeBucket(MakeBucketArgs.builder() .bucket(bucketName) .build()); String policyJson = "{\n" + "\t\"Version\": \""+new SimpleDateFormat("yyyy-mm-dd").format(System.currentTimeMillis())+"\",\n" + "\t\"Statement\": [{\n" + "\t\t\"Effect\": \"Allow\",\n" + "\t\t\"Principal\": {\n" + "\t\t\t\"AWS\": [\"*\"]\n" + "\t\t},\n" + "\t\t\"Action\": [\"s3:GetBucketLocation\", \"s3:ListBucket\", \"s3:ListBucketMultipartUploads\"],\n" + "\t\t\"Resource\": [\"arn:aws:s3:::" + bucketName + "\"]\n" + "\t}, {\n" + "\t\t\"Effect\": \"Allow\",\n" + "\t\t\"Principal\": {\n" + "\t\t\t\"AWS\": [\"*\"]\n" + "\t\t},\n" + "\t\t\"Action\": [\"s3:AbortMultipartUpload\", \"s3:DeleteObject\", \"s3:GetObject\", \"s3:ListMultipartUploadParts\", \"s3:PutObject\"],\n" + "\t\t\"Resource\": [\"arn:aws:s3:::" + bucketName + "/*\"]\n" + "\t}]\n" + "}\n"; minioClient.setBucketPolicy(SetBucketPolicyArgs.builder().bucket(bucketName).config(policyJson).build()); log.info("buckets:【{}】,创建[readwrite]策略成功!", bucketName); } else { log.info("minio bucket->>>【{}】already exists", bucketName); } } catch (Exception e) { e.printStackTrace(); return false; } return true; }
这一块报错是因为文件名写错了🤣,注意在将文件上传到服务器的过程中修改了文件名:
文件名的格式为:yyyy-mm/dd/
+uuid
+文件后缀
