This article mainly introduces Ubuntu how to configure static IP, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Execute the command:

The code is as follows:

Vim / etc/network/interfaces

The editing content is as follows:

The code is as follows:

Auto lo

Iface lo inet loopback

# configuration of Nic eth0

Auto eth0

Iface eth0 inet static

Address 192.168.1.30 # is set to static IP

Netmask 255.255.255.0

Gateway 192.168.1.1

# dns-nameservers 8.8.8.8

# network 192.168.1.0

# broadcast 192.168.1.255

# the last two are the network number and the broadcast number, which can be calculated by other information, so there is no need to set

# where dns-nameservers is used to specify dns if it is modified as follows / etc/resolv.conf will be reset every time it boots up

# can be used to remove the # and use the dns setting here

Restart takes effect

The code is as follows:

Sudo / etc/init.d/networking restart

If you can't surf the Internet, it could be a dns problem.

The code is as follows:

Sudo vim / etc/resolv.conf

Just set up nameserver 8.8.8.8

If it's not a root account, add sudo.

Yesterday, I set up static IP, but when I turned on my computer today, I found that the server could not connect to the Internet. It was strange. Later, I wondered if I didn't set up DNS, so I used the vi editor to open / etc/resolv.conf:

The code is as follows:

Vi / etc/resolv.conf

Add DNS:

The code is as follows:

Search mydomain.com

Nameserver 61.139.39.73

Nameserver 61.139.2.69

After the configuration is complete, restart the network:

The code is as follows:

/ etc/init.d/networking restart

The problem arises. After restarting the computer, the DNS written in / etc/resolv.conf is cleared again.

Solution.

Write DNS in the / etc/resolvconf/resolv.conf.d/head file.

The code is as follows:

Vi / etc/resolvconf/resolv.conf.d/head

Add DNS:

The code is as follows:

Search mydomain.com

Nameserver 61.139.39.73

Nameserver 61.139.2.69

After the configuration is complete, restart the network:

The code is as follows:

/ etc/init.d/networking restart
