安装完ubuntu后，对系统做如下初始化配置
修改ip地址：
root@s100:~# vim /etc/network/interfaces auto eth0 iface eth0 inet static address 192.168.182.100 netmask 255.255.255.0 gateway 192.168.182.2 dns-nameservers 192.168.182.2
修改完ip地址后重启网卡使配置生效
root@s100:~# /etc/init.d/networking restart
修改操作系统字符集
root@s100:~# vim /etc/default/locale LANG="en_US.UTF-8" LANGUAGE="en_US:en"
修改软件源，这里修改为163的源
root@s100:/etc/apt# cp sources.list sources.list.bak root@s100:/etc/apt# vim sources.list deb http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
修改好软件源后要记得更新软件源仓库
root@s100:/etc/apt# apt-get update root@s100:/etc/apt# apt-get upgrade
有了软件源就可以下载软件包了，比如这里下载一个ssh远程连接的软件包openssh-server
#先在源上搜索是否由需要下载的软件包 root@s100:~# apt-cache search openssh-server #源上有需要的软件包后，就可以使用apt-get下载了 root@s100:~# apt-get install openssh-server
修改主机名
root@s100:~# vim /etc/hostname s100 #重启主机使配置生效
上面系统初始化配置完成后就可以让这个主机作为模板机，那么在虚拟机中就可以使用这个模板机来连接克隆需要的主机。
