centos7 树莓派3B samba设置成功的分享一下

我的是树莓派3B上刷的centos7最小安装版，sam和nmb服务已经启动，smb.conf设置用testpram检测问题，

# See smb.conf.example for a more detailed config fileor
# read the smb.conf manpage.
# Run 'testparm' to verify the config is correct after
# you modified it.

树莓派的ip为192.168.1.200.

映射\\192.168.1.200\samba就是不通，有人知道是哪里出问题了吗？
