由于fstab写错了，系统进不去，只能进临时的shell。不过挂载的系统都是只读的，肿么办？

 

在shell输入命令

#mount –o remount rw /

 

这样系统就可写了，然后把错误的改掉，输入reboot重启就ok了！

假如在RHEL图形界面下运行system-config-kickstart,出现如下错误。

 
$system-config-kickstart
Loaded plugins: rhnplugin
This system is not registered with RHN.
RHN support will be disabled.
Traceback (most recent call last):
  File "/usr/bin/system-config-kickstart", line 82, in ?
    kickstartGui.kickstartGui(file)
  File "/usr/share/system-config-kickstart/kickstartGui.py", line 171, in __init__
    self.packages_class = packages.Packages(xml, self.kickstartData)
  File "/usr/share/system-config-kickstart/packages.py", line 172, in __init__
    self.y = sckYumBase(pbar)
  File "/usr/share/system-config-kickstart/packages.py", line 147, in __init__
    self.doGroupSetup()
  File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 520, in doGroupSetup
    return self._getGroups()
  File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 581, in _getGroups
    raise Errors.GroupsError, _('No Groups Available in any repository')
yum.Errors.GroupsError: No Groups Available in any repository
 
然后会跳出来一个窗口说，retrieving package information。然后kickstart就会
关闭了。
 
出问题的原因是repo文件的问题，需要检查下。
 
最简单的方法是把/etc/yum.repos.d/目录下面的所有repo文件都重命名到非repo文
件。kickstart用完后再改回来。
