    //对某个盘分区
    # fdisk /dev/sdh
    #Command (m for help): m
    //新增一个分区
    #n
    //此时会让用户选择,建扩展分区还是主分区,我们选择主分区,输入P
    # p 
    //输入分区系号
    # 1
    // 输入分区起始位置、终止位置

  • linux无法上网解决办法

    2009-08-25 14:34:59

    今天遇到个问题,linux安装好,死活无法上网,以是查找原因--->网卡没有激活,而且怎么都没办法激活

    -->究其原因是VMware Tools未安装。网上找了个方法:

    [转+总结]Linux虚拟系统安装VMware Tools总结

    转自中国网络

    一、VMware Tools安装手记(For Linux Guest OS)


    为什么要装 VMware Tools?

    因为它可以改善 Virtual Machine 的运行性能,而且可以让 Host OS 和 Guest OS 互通有无,这样我们就不用伤脑筋,要架设什么服务器,来沟通两个 OS,现在就让我们开始吧!

    VMware Tools所在位置:VMware 安装路径 \VMware\VMware Workstation\linux.iso

    [root@rd01 ~]# mount /cdrom
    # 有时可能加载不了,这时就要先将系统关闭,再手动指定 ISO 映像,看下图
    [root@rd01 ~]# cd /cdrom
    [root@rd01 ~]# ls -a
    [root@rd01 ~]# cp VMwareTools-5.5.1-19175.tar.gz /tmp
    [root@rd01 ~]# cd /tmp
    [root@rd01 ~]# tar zxpf VMwareTools-5.5.1-19175.tar.gz
    [root@rd01 ~]# cd vmware-tools-distrib
    [root@rd01 vmware-tools-distrib]# ./vmware-install.pl
    Creating a new installer database using the tar3 format.

    Installing the content of the package.

    # 安装过程的画面,全部使用默认值,一直按 Enter 就对了

    In which directory do you want to install the binary files?
    [/usr/bin]

    What is the directory that contains the init directories (rc0.d/ to rc6.d/)?
    [/etc/rc.d]

    What is the directory that contains the init scripts?
    [/etc/rc.d/init.d]

    In which directory do you want to install the daemon files?
    [/usr/sbin]

    In which directory do you want to install the library files?
    [/usr/lib/vmware-tools]

    Thepath "/usr/lib/vmware-tools" does not exist currently. This programisgoingto create it, including needed parent directories. Is thiswhatyou want?
    [yes]

    In which directory do you want to install the documentation files?
    [/usr/share/doc/vmware-tools]

    Thepath "/usr/share/doc/vmware-tools" does not exist currently.Thisprogram isgoing to create it, including needed parent directories.Isthis what you want?
    [yes]

    The installation of VMware Tools 5.5.1 build-19175 for Linux completed
    successfully. You can decide to remove this software from your system at any
    time by invoking the following command: "/usr/bin/vmware-uninstall-tools.pl".

    Before running VMware Tools for the first time, you need to configure it by
    invoking the following command: "/usr/bin/vmware-config-tools.pl". Do you want
    this program to invoke the command for you now? [yes]

    You can now run VMware Tools by invoking the following command:
    "/usr/bin/vmware-toolbox" during an XFree86 session.

    To use the vmxnet driver, restart networking using the following commands:
    /etc/init.d/network stop
    rmmod pcnet32
    rmmod vmxnet
    depmod -a
    modprobe vmxnet
    /etc/init.d/network start

    Enjoy,

    [root@rd01 vmware-tools-distrib]# shutdown -r now

     

    总结: 1 VM 安装linux时选择桥接方式

          2 新手CP命令不熟悉,可以直接像windows一样文件复制,不用命令;

    例如:[root@rd01 ~]# cp VMwareTools-5.5.1-19175.tar.gz /tmp

     就直接进入linux系统把 VMwareTools-5.5.1-19175.tar.gz 复制到 tmp文件下。

          3 玩linux命令一定要注意格式,如[root@rd01 ~]# cp VMwareTools-5.5.1-19175.tar.gz /tmp  如果“/tmp”无空格 肯定不行
