然后就是安装vmware tools了，解压缩之后，以root身份运行vmware-install.pl文件，一路回车即可完成安装，安装完成之后重启虚拟机。
安装centos的yum的步骤：
1.删除RedHat原有的yum：
rpm -aq|grep yum|xargs rpm -e --nodeps
2.下载yum安装组件：（随本机安装版本而定）
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-3.2.29-30.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
如果不能下载也可以使用自己另外下载的centos里面的安装包
3.进行安装yum
最后两个包一块安装，会相互依赖
4.在/etc/yum.repos.d/文件夹下新建一个名为rhel-debuginfo.repo的文件，使用gedit输入以下的内容:
[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6.3/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6.3/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#packages used/produced in the build but not released

[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/6.3/centosplus/$basearch/
gpgcheck=1
enabled=0
5.yum clean all
6.这时候也可以测试一下yum命令是否可用，也可以使用yum update进行升级。
yum install vim
