1. 安裝rpmfusion源，它有非常多的免費和非免費的軟件，音視頻解碼器。
現在rpmfusion有3個不同的源：
一個是穩定版：Fedora16， fedora17用的。
另一個是fedora18的分支，
第三個是fedora19的開發版： Rawhide
現在穩定版用起來還有一些問題，會報錯：
“GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-18-i386”
只能用fedora18這個分支版本:
sudo yum localinstall --nogpgcheck \
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-branched.noarch.rpm \
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-branched.noarch.rpm \
穩定版本的下載地址：
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
現在發現按照這個系統分類的源可能要更好一點：
Fedora 14的源：
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-14.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-14.noarch.rpm
Fedora 15的源：
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-15.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-15.noarch.rpm
Fedora 16的源：
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-16.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-16.noarch.rpm
Fedora 17的源：
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-17.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-17.noarch.rpm
Fedora 18的源：
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-18.noarch.rpm
現在升級一下系統：
sudo yum -y update
安裝一下對我有用的一些軟件包，有些包比較大，你也可以不安裝， 比如 texlive。
自己選擇吧。
sudo yum -y install yum-fastestmirror unrar thunderbird emacs ibus-table \
RedHat-lsb gstreamer-plugins-bad gstreamer-plugins-ugly gstreamer-ffmpeg \
compat-libstdc++-33 NetworkManager-devel python-gevent tracker-ui-tools qemu \
libpciaccess-devel xorg-x11-util-macros llvm-devel mtdev* mutt msmtp tftp \
tftp-server policycoreutils-gui mtd-utils mtd-utils-ubi vim ibus-pinyin \
gnome-tweak-tool ckermit stardict stardict-dic-zh_CN stardict-dic-en texlive \
ibus-table-chinese-wubi-haifeng gnash smplayer vlc samba
安裝chrome
wget https://dl.google.com/linux/direct/google-chrome-stable_current_i386.rpm
rpm -ivh google-chrome-stable_current_i386.rpm
安裝 flash plugin：
wget http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
rpm -ivh adobe-release-i386-1.0-1.noarch.rpm
sudo yum -y install flash-plugin
安裝音視頻解壓器：
wget http://www1.mplayerhq.hu/MPlayer/releases/codecs/all-20110131.tar.bz2
tar jxf all-20110131.tar.bz
sudo mkdir -p /usr/lib/codecs
sudo mv all-20110131/* /usr/lib/codecs
配置samba
sudo smbpasswd -a -U your_username #設置登陸的用戶名和密碼，你可以運行 whoami 查看你的用戶名
sudo systemctl enable smb.service # 開機啟動samba
sudo systemctl start smb.service # 立即啟動samba
sudo systemctl restart smb.service # 立即重啟samba
firewall-cmd --add-service=samba --timeout=10 # 配置防火牆，讓其它電腦能訪問你的電腦。
下面是一個簡單配置示例：
mkdir /home/public
chmod 777 /home/public
[share]
comment = Galen's Share
path = /home/public
writable = yes
valid users = your_username # 你可以運行 whoami 查看你的用戶名
配置好後，記得重啟samba （sudo systemctl restart smb.service）
