         # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

         # [新增]全部用戶的根目錄（對匿名用戶無效） 
        
         local_root=/yddata

四、新增ftp用戶併爲其設置密碼

4.一、具體操做：socket

      
          1 
        
          2 
        
         [root@localhost ~]# useradd ftpuser -s /sbin/nologin 
        
         [root@localhost ~]# passwd ftpuser

五、編輯user_list文件，給予ftpuser用戶訪問ftp權限

5.一、vim /etc/vsftpd/user_listasync

5.二、在文件末尾加入ftpuser並保存tcp

六、創建可訪問目錄並指定用戶

6.一、具體操做：ide

      
          1 
        
          2 
        
          3 
        
         [root@localhost ~]# mkdir -p /yddata 
        
         [root@localhost ~]# chown -R ftpuser /yddata/      #注意後面有個/ 
        
         [root@localhost ~]# chmod -R 755 /yddata
