Install ubuntu-server16.0, set WiFi

Want to install a server version of the Linux system to play, the following record of the pits encountered.

1: Installation language selected in English: It may be because of other reasons, I chose the text when the installation failed, the last time I chose Chinese success.

2: Previously installed an Ubuntu, the back thought of directly covering the Ubuntu partition on it, but it turned out to be very tragic, it is recommended that the small partners to cover the idea of the previous Ubuntu partition is deleted, only one usable large partition is good, the dual system does not matter, the Linux partition is more scattered , Windows generally on the CDE three disk, the Linux partition is deleted is OK.

3: The main detail record how to set WiFi problem:

First look at the information of their network card: The General people are eth0, and wlan0, but in ubuntu-server16.0 inside became enp4s0 and Wlp5s0, is the first pit bar,

ubuntu-server16.0 itself does not have a wpa_supplicant, so the first must practice wired network installation

Install wpasupplicant

Write Wifi-ssid and password to a configuration file

Wpa_passphrase SSID password > xxx.conf

Edit the network configuration file vi/etc/network/interfaces

SOURCE/ETC/NETWORK/INTERFACES.D/*# The loopback network Interfaceauto loiface Lo inet Loopbackauto Wlp5s0iface Wlp5s0 inet dhcpwpa-conf/home/ubuntu/xxx.conf# The primary network interface

There are several ways to get an IP address:

Get IP address automatically: If not, you can reboot first.

Dhclient Wlp5s0

Or get the IP manually: if not, you can reboot first.

• -B-Fork into background
• -c filename-Path to configuration file
• -i interface-Interface to listen on

Wpa_supplicant-I  wlp5s0  -c/home/ubuntu/xxx.conf

The road has always felt very flat, the road ahead always feel very rugged.
