3.  vim /etc/fdfs/mod\_fastdfs.conf

修改为以下配置  
connect\_timeout=10 \# 客户端访问文件连接超时时长（单位：秒）  
tracker\_server=192.168.1.120:22122 \# tracker服务IP和端口（更换成自己机器的IP）  
url\_have\_group\_name=true \# 访问链接前缀加上组名  
store\_path0=/usr/local/fdfs/storage \# 文件存储路径

复制 FastDFS的部分配置文件到/etc/fdfs目录

将文件中，原来的server 80\{ …\} 部分代码替换为如下代码：

server {
    	listen 80;
    	server_name localhost;
    	# 监听域名中带有group的，交给FastDFS模块处理
    	location ~/group([0-9])/ {
    		ngx_fastdfs_module;
    	}
    	location / {
    		root html;
    		index index.html index.htm;
    	}
    	error_page 500 502 503 504 /50x.html;
    	location = /50x.html {
    		root html;
    	}
    }

启动nginx

4.  ./nginx -s reload \# 重新加载配置

### 关闭防火墙 ###

查看防火墙的状态的命令为：sudo systemctl status firewalld。  
打开防火墙的方式有两种，一种是打开后重启会恢复回原来的状态，命令为：sudo systemctl start firewalld；  
另一种是打开后重启不会恢复到原来的状态，命令为：sudo systemctl enable firewalld，这种方式输入命令后要重启系统才会生效。  
关闭防火墙的方式也有两种，和打开相对应，命令分别为  
**sudo systemctl stop firewalld**  
**sudo systemctl disable firewalld**

## spring Cloud 整合文件存储微服务 ##

### 添加依赖 ###

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>net.oschina.zcx7878</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27.0.0</version>
        </dependency>
    </dependencies>

### FastDFS配置 ###

在resources文件夹下创建fasfDFS的配置文件fdfs\_client.conf

connect_timeout=60
    network_timeout=60
    charset=UTF-8
    http.tracker_http_port=80
    # 配置成自己的IP地址
    tracker_server=192.168.xx.xx:22122

connect\_timeout：连接超时时间，单位为秒。  
network\_timeout：通信超时时间，单位为秒。发送或接收数据时。假设在超时时间后还不能发送或接收数据，则本次网络通信失败  
charset： 字符集  
http.tracker\_http\_port ：.tracker的http端口  
tracker\_server： tracker服务器IP和端口设置

### application.yml配置 ###

在resources文件夹下创建application.yml

spring:
      servlet:
        multipart:
          max-file-size: 10MB # 单个文件大小
          max-request-size: 10MB # 总上传数据大小
      application:
        name: file-server
    server:
      port: 7008

max-file-size是单个文件大小，max-request-size是设置总上传的数据大小

### 文件上传 ###

**件信息封装**  
文件上传一般都有文件的名字、文件的内容、文件的扩展名、文件的md5值、文件的作者等相关属性，我们可以创建一个对象封装这些属性，代码如下：  
创建com.ddz.entity.FastDFSFile代码如下：

package com.ddz.entity;
    
    import java.io.Serializable;
    import java.util.Arrays;
    
    public class FastDFSFile implements Serializable {
        
        //文件名字
        private String name;
        //文件内容
        private byte[] content;
        //文件扩展名
        private String ext;
        //文件MD5摘要值
        private String md5;
        //文件创建作者
        private String author;
    
        public String getName() {
        
            return name;
        }
    
        public void setName(String name) {
        
            this.name = name;
        }
    
        public byte[] getContent() {
        
            return content;
        }
    
        public void setContent(byte[] content) {
        
            this.content = content;
        }
    
        public String getExt() {
        
            return ext;
        }
    
        public void setExt(String ext) {
        
            this.ext = ext;
        }
    
        public String getMd5() {
        
            return md5;
        }
    
        public void setMd5(String md5) {
        
            this.md5 = md5;
        }
    
        public String getAuthor() {
        
            return author;
        }
    
        public void setAuthor(String author) {
        
            this.author = author;
        }
    
        @Override
        public String toString() {
        
            return "FastDFSFile{" +
                    "name='" + name + '\'' +
                    ", content=" + Arrays.toString(content) +
                    ", ext='" + ext + '\'' +
                    ", md5='" + md5 + '\'' +
                    ", author='" + author + '\'' +
                    '}';
        }
    }

创建一个FileController，在该控制器中实现文件上传操作，代码如下：

@RestController
    @CrossOrigin
    public class FileController {
        
        /***
         * 文件上传
         * @return
         */
        @PostMapping(value = "/upload")
        public String upload(@RequestParam("file") MultipartFile file) throws Exception {
        
            //封装一个FastDFSFile
            FastDFSFile fastDFSFile = new FastDFSFile(
                    file.getOriginalFilename(), //文件名字
                    file.getBytes(),            //文件字节数组
                    StringUtils.getFilenameExtension(file.getOriginalFilename()));//文件扩展名
    
            //文件上传
            String[] uploads = FastDFSUtil.upload(fastDFSFile);
            //组装文件上传地址
            return FastDFSUtil.getTrackerUrl()+"/"+uploads[0]+"/"+uploads[1];
        }
    }

Postman测试文件上传  
选择post请求方式，输入请求地址
