详解Nginx搭建图片服务器过程

在此之前如果你是一个Nginx新手可以先参阅：

Windows nginx安装教程及简单实践

linux下安装nginx（图文教程）

本章知识点

效果图：

需求：实现图片的上传和批量上传

技术：Nginx，Vsftpd，Spring，SpringMVC，KindEditor，CentOS

说明：本章节内容主要是实现图片的上传功能。使用 KindEditer 是为了更好的演示图片的上传，回显，批量效果。后台代码与KindEditer没有直接关系，放心阅读。另外源码中有Mybatis的jar，不用理会，本章内容用不到，是为后续内容做准备！

源码：见文章底部

场景：用户将图片上传到 tomcat 服务器上，再由 tomcat 服务器通过FTP上传到 Nginx 服务器上。

项目结构：

单元测试

首先要攻破核心技术。通过单元测试实现图片上传的功能。

package com.itdragon.test;import java.io.File;import java.io.FileInputStream;import org.apache.commons.net.ftp.FTP;import org.apache.commons.net.ftp.FTPClient;import org.junit.Test;public class PictureFTPTest {  // 测试 ftp 上传图片功能  @Test  public void testFtpClient() throws Exception {    // 1. 创建一个FtpClient对象    FTPClient ftpClient = new FTPClient();    // 2. 创建 ftp 连接    ftpClient.connect("192.168.0.11", 21);    // 3. 登录 ftp 服务器    ftpClient.login("ftpuser", "root");    // 4. 读取本地文件    FileInputStream inputStream = new FileInputStream(new File("F://hello.png"));    // 5. 设置上传的路径    ftpClient.changeWorkingDirectory("/usr/local/nginx/html/images");    // 6. 修改上传文件的格式为二进制    ftpClient.setFileType(FTP.BINARY_FILE_TYPE);    // 7. 服务器存储文件，第一个参数是存储在服务器的文件名，第二个参数是文件流    ftpClient.storeFile("hello.jpg", inputStream);    // 8. 关闭连接    ftpClient.logout();      }  }

说明：这里的ip地址，端口，ftp用户名，密码，本地文件路径，以及Nginx服务器图片路径等，这些字符串参数都要根据自己实际设置的来填写的。如果你的Nginx和Vsftpd安装是按照我提供的链接来做的。那你只需要改ip地址即可。

Maven 的Web 项目

搭建Maven的Web 项目，之前有写过。这里就不过多描述。

项目核心配置文件

首先是 Maven 的核心文件 pom.xml
