Nginx怎么搭建图片服务器

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();        }    }
