每次安裝swftools都需要重新編譯太麻煩了，就想着直接做個rpm包，留備使用，具體過程如下
1) 下載swftools源碼
http://www.swftools.org/swftools-2013-04-09-1007.tar.gz
2) 安裝rpm包製作工具；
$ sudo yum install -y rpm-build rpmdevtools
3) 運行 rpmdev -setuptree 來生成一個 rpm 包的骨架目錄
# rpmdev -setuptree
4) 在 ~/rpmbuild/SPECS 目錄下用 rpmdev-newspec 來生成一個 spec 骨架文件
# rpmdev -newspec swftools.spec
5) 編輯swftools.spec 文件，具體內容如下：
Name: swftools

%files
%defattr(-,root,root)
/usr/local/swftools

%changelog
6) 編譯rpm
#Rpmbuild –bb swftools.spec
7) 安裝驗證
Rpm –I ../RPMS/X86_64/swftools-0.9.2-1.el7.centos.x86_64.rpm
(如果已經裝過則運行rpm –e swftools卸載)
