Raspberry Pi no IP address?
提问by Slidon
I want to transfer some files from my Mac to my Raspberry Pi via SSH, but when I try to find the Raspberry Pi's IP address with the ifconfig command in the lx terminal, the line which everyone says tells you the IP address is not there!, it's just gone. My terminal looks like this:
我想通过 SSH 将一些文件从我的 Mac 传输到我的 Raspberry Pi，但是当我尝试在 lx 终端中使用 ifconfig 命令查找 Raspberry Pi 的 IP 地址时，每个人都说的那行告诉您 IP 地址不存在！ ，刚刚没了。我的终端看起来像这样：
eth0 Link encap:Ethernet HWaddr b8:27:eb:63:40:b8
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:27224 errors:0 dropped:0 overruns:0 frame:0
TX packets:733 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:2801074 (2.6 MiB) TX bytes:107019 (104.5 KiB)
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

Because this is not from my actual Raspberry Pi, please don't make deductions from it. It's just since I can't transfer files from the Raspberry Pi I can't get a copy of the actual text.
因为这不是来自我实际的 Raspberry Pi，请不要从中进行推断。只是因为我无法从 Raspberry Pi 传输文件，所以我无法获得实际文本的副本。
Sorry for the code mess up, it looks exactly like this website: http://learn.adafruit.com/adafruits-raspberry-pi-lesson-3-network-setup/finding-your-pis-ip-address
抱歉代码搞砸了，它看起来就像这个网站：http: //learn.adafruit.com/adafruits-raspberry-pi-lesson-3-network-setup/finding-your-pis-ip-address
Except without line 2 in ethO.
除了在 ethO 中没有第 2 行。

You can add the IP address (until next reboot) with:
您可以添加 IP 地址（直到下次重新启动）：
sudo ip addr add 192.168.0.100/32 dev eth0
回答by Dead-coder
You can also give your Raspberry Pi an IP address by adding 'ip = 192.168.0.4' at the end of cmdline.txt
您还可以通过在 cmdline.txt 末尾添加“ip = 192.168.0.4”来为您的 Raspberry Pi 提供 IP 地址
Do that using the command:
使用以下命令执行此操作：
sudo nano /boot/cmdline.txt
Make sure you add nothing else, not even a space or a return. After that, reboot your Raspberry Pi and type hostname -Ito see if the IP address is set.
确保不添加任何其他内容，甚至不添加空格或回车。之后，重新启动您的 Raspberry Pi 并键入hostname -I以查看是否设置了 IP 地址。

Configure your inet on the Raspberry Pi for auto (DHCP). Then, assign a fixed IP address to the Raspberry Pi using your router. That's very convenient and when considering the default configuration of the Raspberry Pi then you don't have to modify anything.
在 Raspberry Pi 上将您的 inet 配置为自动 ( DHCP)。然后，使用路由器为 Raspberry Pi 分配一个固定的 IP 地址。这非常方便，在考虑 Raspberry Pi 的默认配置时，您无需修改任何内容。
The appropriate line in /etc/network/inferfacesis:
适当的行/etc/network/inferfaces是：
iface eth0 inet dhcp
Regarding the router configuration: That's up to your device, but the manual should cover it.
关于路由器配置：这取决于您的设备，但手册应涵盖它。
