FTP和nginx搭建檔案存取器

FTPUtil工具類       --檔案上傳(在多tomcat時,檔案不能存到tomcat裡,需要使用ftp和nginx搭建一個存檔案,讀取檔案的地方)

安裝FTP伺服器  執行並登陸  測試:在瀏覽器上輸入ftp:****** ******為ip

需要注意的是,在伺服器或者linux上需要建立ftp使用者,將ftp上傳檔案的資料夾使用者設為ftp使用者

下圖的ftp.server.http.prefix的值為nginx代理的域名

public class FTPUtil {
    private static  final Logger logger = LoggerFactory.getLogger(FTPUtil.class);

    private static String ftpIp = PropertiesUtil.getProperty("ftp.server.ip");
    private static String ftpUser = PropertiesUtil.getProperty("ftp.user");
    private static String ftpPass = PropertiesUtil.getProperty("ftp.pass");

    public FTPUtil(String ip,int port,String user,String pwd){
        this.ip = ip;
        this.port = port;
        this.user = user;
        this.pwd = pwd;
    }

    public static boolean uploadFile(List<File> fileList) throws IOException {
        FTPUtil ftpUtil = new FTPUtil(ftpIp,21,ftpUser,ftpPass);
        logger.info("開始連線ftp伺服器");
        //注意:如果nginx代理指向的資料夾中包括img資料夾,訪問圖片時需要在mmall.properties的ftp.server.http.prefix值後新增img/
        boolean result = ftpUtil.uploadFile("img",fileList);
        logger.info("結束上傳,上傳結果:{}",result);
        return result;
    }

    private boolean uploadFile(String remotePath,List<File> fileList) throws IOException {
        boolean uploaded = false;
        FileInputStream fis = null;
        //連線FTP伺服器
        if(connectServer(this.ip,this.port,this.user,this.pwd)){
            try {
                ftpClient.changeWorkingDirectory(remotePath);  //需不需要切換資料夾
                ftpClient.setBufferSize(1024);
                ftpClient.setControlEncoding("UTF-8");
                ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);  //二進位制檔案型別
                ftpClient.enterLocalPassiveMode();  //開啟本地的被動模式
                for(File fileItem : fileList) {
                    fis = new FileInputStream(fileItem);
                    ftpClient.storeFile(fileItem.getName(), fis);
                    uploaded = true;
                }
            } catch (IOException e) {
                logger.error("ftp上傳檔案異常",e);
                e.printStackTrace();
            } finally {
                fis.close();
                ftpClient.disconnect();
            }
        }
        return uploaded;
    }

    private boolean connectServer(String ip,int port,String user,String pwd){
        boolean isSuccess = false;
        ftpClient = new FTPClient();
        try {
            ftpClient.connect(ip);  //連線ftp
            isSuccess = ftpClient.login(user,pwd);  //登陸ftp
        } catch (IOException e) {
            logger.error("連線FTP伺服器異常",e);
        }
        return isSuccess;
    }


    private String ip;
    private int port;
    private String user;
    private String pwd;
    private FTPClient ftpClient;

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    public FTPClient getFtpClient() {
        return ftpClient;
    }

    public void setFtpClient(FTPClient ftpClient) {
        this.ftpClient = ftpClient;
    }
}

nginx部分:

在瀏覽器中輸入一個網址會先check一下你本地的hosts檔案,如果有做對映的話就直接通過對映的ip訪問你的web伺服器(這邊是nginx) 當這個請求被nginx 獲得後  他會check一下請求的域名和servername是否匹配,

匹配到的話就根據相應的配置返回內容,沒有匹配到的話就根據預設的配置返回內容

linux下

在/usr/local/conf中vim nginx.conf新增include vhost/*.conf;  即匯入在conf下的所有以.conf結尾的配置檔案

在/conf中mkdir vhost

在/etc/hosts中新增例如:******** image.imooc.com   前面是伺服器ip 後面是域名

在/conf/vhost中vim image.imooc.com.conf(可以與/etc/hosts中的名字不一致)

編輯image.imooc.com.conf   監聽80埠,碰到image.imooc.com轉到location 裡面

server { 
	listen 80; 
	autoindex off;   //是否顯示目錄
	server_name image.imooc.com; 
	access_log /usr/local/nginx/logs/access.log combined; 
	index index.html index.htm index.jsp index.php; 
	#error_page 404 /404.html; 
	if ( $query_string ~* ".*[\;'\<\>].*" ){
		return 404;
		} 
	location ~ /(mmall_fe|mmall_admin_fe)/dist/view/* {
		deny all; 
	} 
	location / {
		root /ftpfile/img/; 
		add_header Access-Control-Allow-Origin *; 
	} 
} 

重啟:   ../../sbin/nginx -s reload

window

在nginx的安裝目錄下找到conf資料夾下的nginx.conf裡面新增include vhost/*.conf

在/conf中mkdir vhost

在/conf/vhost中vim image.imooc.com裡面

server { 
	listen 80; 
	autoindex on; 
	server_name image.imooc.com www.image.imooc.com; 
	access_log D:/nginx/nginx-1.10.2/logs/access.log combined; 
	index index.html index.htm index.jsp index.php; 
	#error_page 404 /404.html; 
	if ( $query_string ~* ".*[\;'\<\>].*" ){ return 404; } 
	location ~ /(mmall_fe|mmall_admin_fe)/dist/view/* { deny all; } 
	location / { 
	root D:\ftpfile;
	add_header Access-Control-Allow-Origin *; } 
} 
在c:\Windows\System32\drivers\etc\hosts中新增
例如:****** www.imooc.com   前面是伺服器ip 後面是域名

nginx.exe -t 測試配置檔案是否正確
nginx.exe -s reload 重啟
