1、给firefox装adobe插件：
1 下载install_flash_player_10_linux.tar.zip，解压tar -zxvf install_flash_player_10_linux.tar.zip得到libflashplayer.so
2 将libflashplayer.so拷贝到/usr/lib64/firefox/plugins这个目录下(我的系统是64位)
3 重启firefox即可
2、centos7装StarDict
1 下载RPM包：http://pkgs.org/centos-6-rhel-6/naulinux-school-x86_64/stardict-3.0.2-1.el6.x86_64.rpm/download/
2 yum localinstall stardict-3.0.2-1.el6.x86_64.rpm
3 下载并安装支持StarDict的简体中文词典（http://abloz.com/huzheng/stardict-dic/zh_CN/）并将解压文件放在/usr/share/stardict/dic/下。
3 、epel yum源安装

vmware下安装vmware-tool
1、检查系统是否安装了kernel-devel、gcc（非图形界面还有perl）,如果没有安装就要先安装这些工具。具体如下：
首先挂载安装光盘mount /dev/cdrom /mnt，再执行cd /etc/yum.repos.d，rm -rf * ，vim my.repos 在my.repos中编辑如下内容：
name=my
baseurl=file:///mnt
enable=1
gpgcheck=0
配置好yum源后就可以yum install kernrl-devel gcc 了
2、点击虚拟机上的vm-install vm-tool。再挂载光盘，解压缩里面的VMw*-gz到/opt文件中
3、cd到/opt/vm*下，执行里面的*.pl文件,再一路回车即可.
