对于之前的squeeze用户,升级还是很简单的.国内的用户直接去换一个源就行了

在终端依次输入以下命令,备份老源文件,直接去163下载新源文件即可.

#cp /etc/apt/sources.list /etc/apt/squeeze_sources_list

#wget http://mirrors.163.com/.help/sources.list.wheezy -O /etc/apt/sources.list

或者直接把复制下面的,并且把老的squeeze的注释或者删除掉 www.111com.net

deb http://mirrors.163.com/debian wheezy main non-free contrib
deb http://mirrors.163.com/debian wheezy-proposed-updates main contrib non-free
deb-src http://mirrors.163.com/debian wheezy main non-free contrib
deb-src http://mirrors.163.com/debian wheezy-proposed-updates main contrib non-free

deb http://mirrors.163.com/debian-security wheezy/updates main contrib non-free
deb-src http://mirrors.163.com/debian-security wheezy/updates main contrib non-free

deb http://http.us.debian.org/debian wheezy main contrib non-free
deb http://non-us.debian.org/debian-non-US wheezy/non-US main contrib non-free
deb http://security.debian.org wheezy/updates main contrib non-free

然后

#apt-get update
#apt-get -y upgrade
或者
#apt-get upgrade

过程中有包错误的先解决错误再继续。

升级内核
#apt-get dist-upgrade

中途会弹出一个软件更新的差异的内容,这个直接q退出就行了,(你有耐心也可以看完的..)

中途会弹出一些配置的选项窗口, 简单读完了看你需要是否需要重启这些服务, 需要就YES.远程管理的最好

直接默认下来的，之后重新配置。

有网友要我的源文件. 我的加了2个

补充一个添加系统日志的办法

编辑/etc/default/bootlogd
#vim /etc/default/bootlogd
修改BOOTLOGD_ENABLE选项为
BOOTLOGD_ENABLE=Yes
保存退出，以后在启动之后，直接
cat /var/log/boot
