Adobe flash 下载(https://get.adobe.com/flashplayer/) tar.gz版本（注：adobe 提供了yum，rpm，tar.gz和APT四种版本，yum和tar.gz是通用的，而rpm则是以Redhat 为主体的格式）。
tar命令进行解压，得到三个文件：usr文件夹，libflashplayer.so库文件和 readerme.txt文本
readme.txt中详细介绍了安装方法：
Installing using the plugin tar.gz:
o Unpack the plugin tar.gz and copy the files to the appropriate location.
o Save the plugin tar.gz locally and note the location the file was saved to.
o Launch terminal and change directories to the location the file was saved to.
o Unpack the tar.gz file. Once unpacked you will see the following:
+ libflashplayer.so
+ /usr
o Identify the location of the browser plugins directory, based on your Linux distribution and Firefox version
o Copy libflashplayer.so to the appropriate browser plugins directory. At the prompt type:
+ cp libflashlayer.so <BrowserPluginsLocation>
o Copy the Flash Player Local Settings configurations files to the /usr directory. At the prompt type:
+ sudo cp -r usr/* /usr
译文：
1.解压install_flash_player_11_linux_i386.tar.gz
2.找到文件系统中浏览器插件所在的位置，例如在/usr/lib/mozilla/plugins，然后把libflashplayer.so复制到该文件夹中：
sudo cp libflashplayer.so /usr/lib/mozilla/plugins
3.把解压出来的usr文件夹中的各个文件复制到文件系统中的相应位置
sudo cp usr/ /usr
结束。
