Question

我是新来的。

几天前，参加了MS azure活动，今天注册了Azure（免费帐户） VM环境：VM = CentOS 7，apache + php + mysql + vsftpd + phpMyAdmin

一切都已启动并运行，能够通过其公共IP地址访问“info.php” SeLinux =禁用，Firewalld禁用。

我的问题是无法通过Filezilla（PC客户端）连接此服务器。从Windows命令提示符（FTP / put）工作，能够上传文件。但是通过Filezilla

我认为是因为网络安全组设置了入站和出站规则，需要打开一些端口，但不确定，因为我试过打开1024-65535所有允许，仍然无法正常工作。

Answer 1

如果使用被动模式FTP，则应打开Azure NSG上需要的端口20,21和端口（入站规则）。您可以查看/etc/vsftpd.conf

pasv_enable=YES
pasv_min_port=60001
pasv_max_port=60005

对于此示例，您应该在Azure NSG（入站规则）上打开端口60001-60005。

Filezilla（客户端）连接的网络安全组
