lnmp 在 debian5.0 下安装总是失败的原因

说下我的VPS配置：

IXwebhosting X2 Debian VPS 系统

#uname -a
Linux rockscrusher.com 2.6.18-028stab099.3 #1 SMP Wed Mar 7 15:20:22 MSK 2012 x86_64 GNU/Linux
# head -n 1 /etc/issue
Debian GNU/Linux 6.0 \n \l

这是升级后的，以前是5.0的。

vpser.net 上的lnmp安装或lnmpa安装，只适合它推荐的几款VPS的上安装。其它的VPS失败率比较高，比如我的这个系统。

在安装中一般会出现的错误是更新源不对。

其中会一直出现下面的循环。

Configuration file `/etc/security/limits.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
  What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
The default action is to keep your current version.

解决方法：

把/etc/apt/sources.list 更换为以下

1
2
3

deb http://archive.debian.org/debian lenny main contrib non-free
deb http://archive.debian.org/debian-security/ lenny/updates main contrib non-free
deb http://archive.debian.org/debian-volatile/ lenny/volatile main contrib non-free

然后更新系统：

1 2	apt-get update apt-get upgrade

另外：

为什么要更新源呢，一般情况下安装lnmpa前更新下系统会比较顺利，因为lnmpa在安装过程中也会更新一些它需要的依赖包。所以这两个命令很重要。

1 2	apt-get update apt-get upgrade
