2、启动服务 

使用vsftpd软件，主要包括如下几个命令：

启动ftp命令#service vsftpd start

停止ftp命令#service vsftpd stop

重启ftp命令#service vsftpd restart

• 3、vsftpd的配置

  ftp的配置文件主要有三个，位于/etc/vsftpd/目录下，分别是：

  ftpusers    该文件用来指定那些用户不能访问ftp服务器。

  user_list   该文件用来指示的默认账户在默认情况下也不能访问ftp

  vsftpd.conf   vsftpd的主配置文件

• 4、以匿名用户为例，我们去掉配置文件vsftpd.conf 里面以下

  anon_upload_enable=YES

  anon_mkdir_write_enable=YES

  两项前面的#号，就可以完成匿名用户的配置，此时匿名用户既可以登录上传、下载文件。记得修改配置文件后需要重启服务。

  5、非匿名账户的创建与使用

  vsftpd服务与系统用户是相互关联的，例如我们创建一个名为test 的系统用户，那么此用户在默认配置的情况下就可以实现登录，如图

  登录后在页面创建名为“aa”的文件夹，同样我们在服务器test用户 的home目录里也可以看到相同的文件。
