无显示器连接树莓派

本文主要讲解无显示连接树莓派

下载镜像

点击这里 下载 ,如图所示:

刻录镜像

1.下载如图所示的程序

2.参考如图制作镜像

开启 SSH

写个空文件文件到 sd 卡中，文件名 SSH，因为树莓派默认把 SSH 给禁止了，我这里用sublime Text 编辑器创建一个空文件保存在 sd 卡的 根目录下

配置 WiFi

写一个配置文件 wpa_supplicant.conf 到 sd 卡的根目录

其中 wpa_supplicant.conf 配置文件如下：

country=GB
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="ssid"

    psk=fd105d44432233221ea8ddc60c4a2da03379fe94432c5e4c1f034b89fe0687288a16fdb4a132693fd
    priority=2 # 优先级，数字越大优先级越高
}
network={
    ssid="iphone"
psk=aa44443bc3ce7326f17b533fdcb57ac35c9914df5be8532ca70a23c153c7c6ac56dbb
    priority=1

如图所示,这里的密码可以使用命令生成

wpa_passphrase "ssid" "password"

连接

然后上电就可以连接了，密码自己登陆无线路由器查看，默认密码 raspberry

SSH is enabled and the default password for the 'pi' user has not been changed.
This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.

重置密码

pi@raspberrypi:~ $ sudo passwd pi
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

无密码登录

我一向不稀罕用密码登录，因为一麻烦 二不安全

Now try logging into the machine, with:   "ssh 'pi@192.168.50.86'"
and check to make sure that only the key(s) you wanted were added.
