This is for the CentOS user out there. Sometimes when you try to search for rpm packages, the only thing that you find is the source file. I like to create rpm file usingfrom source file:
1. save the source file(usually in tar.gz or tar.bz2 format)
2. extract the files-> tar -xvzf filename.tar.gz or tar -xvjf filename.tar.bz2
3. open the folder of the extracted file and find .spec file
4. type-> rpmbuild -bb filename.spec
5. see the error and continue according to the error until you finish creating rpm files
6. type-> rpm -Uvh filename.rpm to install
