网络配置

静态IP

[email protected]:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto ens33
iface ens33 inet static
    address 10.0.0.50
    netmask 255.255.255.0
    network 10.0.0.0
    broadcast 10.0.0.255
    gateway 10.0.0.2
    # dns-* options are implemented by the resolvconf package, if installed
    dns-nameservers 10.0.0.

DHCP动态IP

以DHCP方式配置网卡

编辑文件vi /etc/network/interfaces

并用下面的行来替换有关eth0的行:
# The primary network interface - use DHCP to find our address
auto eth0
iface eth0 inet dhcp

用下面的命令使网络设置生效

/etc/init.d/networking restart

设置主机名称(hostname)

使用下面的命令来设置当前主机的主机名称:

vim /bin/hostname

newname系统启动时,它会从/etc/hostname来读取主机的名称.

 配置DNS

vim /etc/resolv.conf
