創(chuàng)建并啟動(dòng)minIO容器：
這里的 \ 指的是命令還沒有輸入完，還需要繼續(xù)輸入命令，先不要執(zhí)行的意思。
這里的9090端口指的是minio的客戶端端口。雖然設(shè)置9090，但是我們在訪問9000的時(shí)候，他也會(huì)自動(dòng)跳到9090。
9000端口是minio的服務(wù)端端口，我們程序在連接minio的時(shí)候，就是通過這個(gè)端口來連接的。
-v就是docker run當(dāng)中的掛載，這里的/usr/local/mydata/minio/data:/data意思就是將容器的/data目錄和宿主機(jī)的/mydata/minio/data目錄做映射，這樣我們想要查看容器的文件的時(shí)候，就不需要看容器當(dāng)中的文件了。
注意在執(zhí)行命令的時(shí)候，他是會(huì)自動(dòng)在宿主機(jī)當(dāng)中創(chuàng)建目錄的。我們不需要手動(dòng)創(chuàng)建。
minio所上傳的文件默認(rèn)都是存儲(chǔ)在容器的data目錄下的！
假如刪除容器了宿主機(jī)當(dāng)中掛載的目錄是不會(huì)刪除的。假如沒有使用-v掛載目錄，那他在宿主機(jī)的存儲(chǔ)位置的文件會(huì)直接刪除的。
宿主機(jī)的掛載目錄一定是根目錄，如果是相對(duì)路徑會(huì)有問題。還有容器當(dāng)中的目錄也是必須是絕對(duì)路徑（根路徑就是帶/的）。
所謂的掛載其實(shí)就是將容器目錄和宿主機(jī)目錄進(jìn)行綁定了，操作宿主機(jī)目錄，容器目錄也會(huì)變化，操作容器目錄，宿主機(jī)目錄也會(huì)變化。這樣做的目的 可以間接理解為就是數(shù)據(jù)持久化，防止容器誤刪，導(dǎo)致數(shù)據(jù)丟失的情況。
MINIO_ACCESS_KEY:賬號(hào) MINIO_SECRET_KEY:密碼 (正常賬號(hào)應(yīng)該不低于3位，密碼不低于8位，不然容器會(huì)啟動(dòng)不成功)
–console-address 指定客戶端端口
-d --restart=always 代表重啟linux的時(shí)候容器自動(dòng)啟動(dòng)
–name minio 容器名稱

?docker run -p 9000:9000 -p 9090:9090 ?--name minio ?-d --restart=always ?-e "MINIO_ACCESS_KEY=minioadmin" ?-e "MINIO_SECRET_KEY=minioadmin" ?-v /usr/local/mydata/minio/data:/data ?minio/minio server ?/data --console-address ":9090" -address ":9000"

springboot集成minio

一、配置yml文件

#yml配置文件增加如下配置minio:endpoint: http://ip:9000fileUploadUrl: http://ip:9000accessKey: minioadmin (用戶名)secretKey: minioadmin (密碼)bucketName: file (文件組：桶名)

二、引入pom（8與7的方法不適用，以下使用8.0.3）

? ? ? ? <dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.0.3</version></dependency>

三、系統(tǒng)加載minio配置

@Data
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {private String endpoint;private String accessKey;private String secretKey;private String bucketName;@Beanpublic MinioClient minioClient()  {MinioClient minioClient = MinioClient.builder().endpoint(endpoint).credentials(accessKey, secretKey).build();return minioClient;}}
