安装Linux Fedora发行版中的问题以及fedora PPPOE联网问题

发表于 分类于 Valine：

最近在安装fedora时遇到几个问题：

  1. 磁盘分区之后，挂载空间时，显示的可用空间很少。
      这种情况是因为磁盘的类型为动态磁盘，而动态磁盘上是不允许安装系统的。此时需要用磁盘助手 把动态磁盘转换为基本磁盘。转换的过程中最多只能有四个主分区，系统预留了一个，所以你只能有三个磁盘卷。多于三会造成磁盘数据丢失。如果不小心删除了磁盘上的一些数据，可以使用DiskGenius恢复数据，这款软件有破解版的，但不太容易找到。
  2. 装好fedora之后，最重要的问题是联网，试了很多种方法之后，感觉还是PPPOE联网比较好用。下面具体说一下怎样联网。
  • 进入终端输入：su
    输入密码：（root的密码）

    For Solaris, this is likely to be something like/dev/hme0.  
    For Linux, it will be ethX, where 'X' is anumber.  
    (default eth0): #（查看的时候是eth0或enp1s0)

         0 - NONE: This script will not set any firewallrules.  You areresponsible  
             for ensuringthe security of yourmachine.  You areSTRONGLY  
             recommendedto use some kind of firewallrules.

                    to bring itdown.  
           Type '/sbin/pppoe-status/etc/sysconfig/network-scripts/ifcfg-ppp0'  
                    to see the linkstatus.  
    # 然后建立连接：
    [root@localhostedit]: pppoe-start
    # 查看是否连上：
    [root@localhostedit]: pppoe-status 
  • 如果出现linkis up 证明连接成功，去喝杯咖啡，然后就能回来上网了。
  • 如果出现link is down(can’t readPPPD_IDFILE——–）说明没有连接成功，此时要查看自己的参数是否都输入的正确。
