CENTOS 5的虚拟机，怎么从图形界面切换到命令行界面

1.临时切换：
ctrl+alt+1 …… ctrl+alt+6一共六个控制台。
2.永久关闭图形化：
在root下输入 vi /etc/inittab 将init:5修改为init:3

Mysql rpm包安装，不能重定位(relocatable)

rpm包安装异常，--prefix 参数不能重定位，安装到另一个目录的原因，error: package is not relocatable

 

[mysql@test922 ~]$ rpm --install --prefix linuxqq-v1.0.2-beta1.i386.rpm
error: linuxqq is not relocatable

经查找，可以使用下面的命令查看rpm包是否可以重定位，也就是安装到另一个目录。

＃ rpm -qpi linuxqq-v1.0.2-beta1.i386.rpm |head
Name        : linuxqq                      Relocations: (not relocatable)
Version     : v1.0.2                            Vendor: Tencent Inc.
Release     : beta1                         Build Date: 2009年01月05日 星期一 17时31分44秒
Install Date: (not installed)               Build Host: localhost.localdomain
Group       : Internet                      Source RPM: linuxqq-v1.0.2-beta1.src.rpm

Signature   : (none)
Packager    : @Home
Summary     : QQ for Linux v1.0.2 Beta1
Description :


从结果看到
Relocations: (not relocatable)

是无法修改安装目录的，也就是不能重定位，只有去掉 --prefix参数。

先安装别的包，有时就能安装上。是个别包的传输速度问题。

账户不能用问题

提示：this account is currently not available

我是创建了一个新用户。网上查到的处理办法是修改/etc/passwd中shell的值，默认是/sbin/nologin，改成/bin/bash即可。
