This article mainly shows you the "sample Analysis of ubuntu 12.04 server Network configuration", which is easy to understand and well organized. I hope it can help you solve your doubts. Let me lead you to study and learn the article "sample Analysis of ubuntu 12.04 server Network configuration".

Ubuntu 12.04 server Network configuration

Recently, due to work needs, ubuntu 12.04 server version has been installed in the virtual machine.

Because the server version has no interface, many of them need to be configured on their own.

1. Configure the network IP address

Note that this is bridging mode

If you get IP and DNS automatically, you don't have to configure it. IP can be obtained automatically by DHCP.

But servers generally use static IP, so you need to configure it manually.

The network configuration information of ubuntu is placed in / etc/network/interfaces

Sudo vim / etc/network/interfaces

Auto eth0

Iface eth0 inet dhcp

If you configure static ip, add the following:

Auto eth0

Iface eth0 inet static

Address 192.168.1.81

Netmask 255.255.255.0

Gateway 192.168.1.1

If the configuration takes effect, you need to restart the Nic:

Ifconfig eth0 down

Ifconfig eth0 up www.2cto.com

Then use the ifconfig command to see if the ip is configured successfully

2 configure the hostname, in fact, it can not be configured here, in order to build the cluster

Vi / etc/hosts

127.0.0.1 localhost

192.168.1.81 node81

192.168.1.82 node82

192.168.1.83 node83

Vi / etc/hostname

Node81

If the configuration is not successful, you need to restart the network service

/ etc/init.d/networking restart

3. DNS

If it is configured as static IP, the DNS in the DNS file will be gone after each shutdown and power-on.

Dns server information for ubuntu, put in / etc/resolv.conf

Add the dns server address, such as 192.168.1.1, in the above file

Nameserver 192.168.1.1

Permanent DNS

Sudo vi / etc/resolvconf/resolv.conf.d/base

Nameserver 192.168.1.1

When the above is done, generally restart the virtual machine. You can surf the Internet.

4. Virtualbox settings

If set to bridge mode, then the virtual machine system is equivalent to a physical computer, because the network of my school needs to be authenticated, so there is no way to access the Internet.

The bridge mode can be set to static IP.

If the NAT mode is set, the virtual machine can surf the Internet through the host. But ubuntu can not be set to static IP, this problem bothered me for a long time, because there was no way to access the network using NAT mode, and then it was changed to dynamically obtain IP so that I could access the Internet through NAT mode.

In the use of static IP, you can use an agent to surf the Internet.

Modify the .bashrc file by adding:

Http_proxy=proxy:8888 (add a proxy server in a similar format)

Export http_proxy

After saving and exiting:

Source / .bashrc

You can use an agent to surf the Internet in ubuntu server.
