OpenSSH≥4.8支持ChrootDirectory指令。

添加到/etc/sshd_config或/etc/ssh/sshd_config安装程序的全局sshd配置文件为：

Match user ben_files
        # The following two directives force ben_files to become chrooted
        # and only have sftp available.  No other chroot setup is required.
        ChrootDirectory /var/www/vhosts/mydomain.com/files
        ForceCommand internal-sftp
        # For additional paranoia, disallow all types of port forwardings.
        AllowTcpForwarding no
        GatewayPorts no
        X11Forwarding no
