来一发CentOS磁盘分区增加删除
如果您觉得本篇CentOSLinux教程讲得好，请记得点击右边漂浮的分享程序，把好文章分享给你的小伙伴们！Linux硬盘分区（一）：增加********************************
*************************
历程简述
*************************
viewplaincopy
[*]--增加磁盘
[*]#fdisk-l--检察磁盘情形
[*]#fdisk/dev/sdb--为/dev/sdb装备分区
[*]n--增加分区
[*]p/e--主分区/逻辑分区
[*]w--保留加入
[*]#mkdir/data--创立挂载目次
[*]#mkfs.ext3/dev/sdb--格局化磁盘为ext3文件体系
[*]#fdisk-l--再次检察磁盘情形
[*]#mount/dev/sdb/data--挂载磁盘到创立的挂载目次下
[*]#vi/etc/fstab--修正启动主动挂载项
[*]/dev/sdb/dataext3defaults00

2、以下复杂枚举两例，细化操纵历程。

来一发CentOS磁盘分区增加删除
一些显而易见的小错误还是用vi改正比较方便。以后的大一点的程序就得在Linux下调试了，因为有的头文件在VC里面说找不到。? 掌握在Linux系统中安装软件，在安装Linux工具盘后大致日常所需的软件都会有,一般网络提供下载的软件都会有安装说明。 把这个问题放在其他Linux社区请求帮助也是一种选择。如果Linux得不到答案，请不要以为我们觉得无法帮助你。有时只是看到你问题的人不知道答案罢了。这时换一个社区是不错的选择。 用户下达的命令解释给系统去执行，并将系统传回的信息再次解释给用户，估shell也称为命令解释器，有关命令的学习可参考论坛相关文章，精通英文也是学习Linux的关键。 有疑问前，知识学习前，先用搜索。 Linux是参照Unix思想设计的，理解掌握Linux必须按照Unix思维来进行。思想性的转变比暂时性的技术提高更有用,因为他能帮助你加快学习速度。
