本文详细介绍了在Ubuntu环境下配置固定IP地址的方法，包括编辑/etc/network/interfaces、/etc/resolv.conf和/etc/resolvconf/resolv.conf.d/base文件以确保服务器在重启后仍能正常连接网络。

Ubuntu下配置固定IP地址，只需修改三个文件，以保障服务器重启后都能生效：

leekwen@leekwen:~$ 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).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.10.121
netmask 255.255.255.0
gateway 192.168.10.1
leekwen@leekwen:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 202.101.172.46
nameserver 202.101.172.35
leekwen@leekwen:~$ cat /etc/resolvconf/resolv.conf.d/base
nameserver 202.101.172.46
nameserver 202.101.172.35

将/etc/resolv.conf里的内容与/etc/resolvconf/resolv.conf.d/base保持一致。
