docker分布式mount docker分布式文件服务器

首先说一下从零开始自己去搭一个fastdfs挺麻烦，后来看到有人把做好的 docker 镜像传出来了，那搭建起来就很容易了

1.第一步安装docker:

在 root 权限下

yum install -y docker-io #安装docker service docker star #启动docker docker -v # 查看docker版本

yum install -y docker-io #安装docker service docker star #启动docker docker -v # 查看docker版本

2. 拉取镜像

docker pull qbanxiaoli/fastdfs 

docker pull qbanxiaoli/fastdfs

启动 fastdfs

docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=192.168.127.131 -e WEB_PORT=80 -v ${HOME}/fastdfs:/var/local/fdfs qbanxiaoli/fastdfs

docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=192.168.127.131 -e WEB_PORT=80 -v ${HOME}/fastdfs:/var/local/fdfs qbanxiaoli/fastdfs

IP 后面是你的服务器公网ip或者虚拟机的IP，-e WEB_PORT=80 指定 nginx 端口 

测试fastdfs是否搭建成功

docker exec -it fastdfs /bin/bash echo "Hello FastDFS!">index.html fdfs_test /etc/fdfs/client.conf upload index.html

能返回 url 就意见搭建成功

这样 fastdfs 就搭建好啦。

下面进入 Spring Boot 整合部分

<groupId>com.github.tobato</groupId>
   <artifactId>fastdfs-client</artifactId>
<version>1.26.2</version>

Spring Boot 基础教程及实战示例：https://github.com/javastacks/spring-boot-best-practice

在 Spring Boot 启动类上加：

@Import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)

运行测试类

返回的 url 就是能访问的地址
